Interview with Paul Hollowaty of Speed 3D, 3D Printing at Mach 3, Printing glasses for Dyslexic children, and $100 million

Welcome to 3d from nothing powered by metal mix. The show where you learn all about 3d printing and additive technology. I’m your host, Tom Gendich.  Metal mite is a full service machine shop that specializes in five and six axis. CNC, machining, CNC, grinding while your EDM and 3d printing. We have a 50 plus year.

History in this corporation started by my father, Michael gender. The third I took over as CEO in 2009, and I’m continuing the manufacturing legacy today as a third generation owner. In these programs you’ll learn. What kinds of printers are out there? What kinds of materials you can print on, who are using these printers?

What kinds of things you should be looking at printing as well as hearing from experts in the field, through interviews that we’ll be conducting as always, you can go to our website, 3d from You’ll find some free giveaways, learn all about what we’re doing. See the links to different things we comment about and learn more about where our name comes from, which was my father, who always said someday we’ll make parts out of nothing.

And that’s what we’re doing today with 3d printing and additive technology.

We’re so excited today to have Paul Holowaty with us. Paul was born in a manufacturing business,

similar to me, he’s the third generation to come on the scene, making parts. Through a vast number of changes. Paul made the switch to start selling both software. And additive manufacturing machines at one point, even becoming the number one salesman for Stratasys in the world.

Today Paul is bringing us some amazing new technology that makes manufacturing easier, faster, and more cost effective. We’re excited to hear how 3d printing can be done at Mach three. Paul welcome to our show.

Thanks, Tom. Glad to be here. Thanks for inviting me.  I’d like to talk to you today about our technology, which is pretty amazing. The name of the company is speed. 3d. Started by our two co-founders Steve Camilleri , Byron Kennedy. And they  had a prior company building electric motors. -Byron Kennedy and Steven Camilleri have worked together for 15 years, first meeting as members of the Charles Darwin University World Solar Car Challenge team. They raced the ‘Desert Rose’ together between 1987 and 2005. After many successful years racing against industry giants such as General Motors and Honda, in 2000 the Desert Rose was awarded the world speed record for solar cars, averaging 107kmph.

In 2002 they formed ‘In Motion Technology’ (IMT) to commercialize the axial flux motor technology developed for the Desert Rose. This motor technology is now utilized around the world and is arguably one of the most successful commercials spinoffs from solar car racing. With the proceeds of a successful sale of IMT the pair formed SPEE3D.

They had difficulty finding castings.

with a proper lead time and cost effectively. They looked at metal 3d printing at the time and it just, it wasn’t fast enough, and it wasn’t cost effective. In us, they looked Around a different technology. Our technology called cold spray additive manufacturing. Was very interesting to them and

At the time it was just being used for repair and coding. What they did is developed a very sophisticated software that allowed them to take a repair technology and turn it into an additive manufacturing technology. And that’s what we have today. So just to back up a little bit on that, on this show, we’ve talked about a couple of the processes, like selective laser centering. I mentioned before the EOS machine that I was introduced to 20 years ago and then, and metal might ourselves. We bought a 3d systems machine.

Three years ago. And so we’re familiar with how you center that metal with the laser beam. I said, I dumb it down for my, for myself basically, but I say laser beam into kitty litter and we make these parts. So you’re saying that this technology is not using any, you’re not using any lasers. You’re not centering metal in a hot format.

Correct. So we’re building parts in a solid state. And the way the technology works. It’s a very cost-effective. It’s a way of. Printing metal, 3d printing parts. We’re using compressed air as opposed to a nerve gas. And what we’re doing is we’re heating up the compressed air. Inserting the metal powder particles and then running it through a converging and diverging rocket nozzle.

It accelerates the air up to a thousand. Meters per second. The powder particles then hit a substrate. And stick to that substrate. So we’re converting thermal energy to kinetic energy. And it’s producing parts, large parts in a really fast, in the most cost, cost effective manner. So let’s put that into a into layman’s terms. So a thousand meters per second, is that about Mach three? Is that what we’re looking at? That’s close to Mach three, which is three times the speed of sound. Correct.

You’re heating it up and propelling it through this rocket tube. At my, at three times the speed of sound. And then it hits a substrate, which is essentially a plate. And it, are we still calling it fusing? It’s. Is this like cold fusion. You’re fusing it to a plate at that point. Yeah. It it’s plastic defamation.

Okay. So it’s hitting the substrate and just sticking and the deposition efficiencies 90 plus percent. The rest of them. Powder particles get sucked up into a dust extractor. It’s a very clean process. So yeah. To go back. One other term you use is very quickly. So to put a little bit of time around very quickly, I happened to catch a video before you and I talked and we made a hammer, a common use hammer. Somebody has around the house.

Your machine made it in six minutes, six minutes on a trade show floor. In front of a bunch of people on the floor. And so these people didn’t have to wear the respirators and the ventilators and the new Keeler suit that we have to wear when we unload our. Yeah. Our SLS machine. So when you say it’s very clean, it’s environmentally friendly. No, there’s no carcinogens in the air, correct? Similar to a sandblaster.

Somebody is opening the sandblast door. It would be similar to a sandblaster in that. The only time you really have to wear a respirator. Is when you’re loading powder. Okay. The. As I mentioned the deposition efficiencies 90 plus percent. So the rest gets sucked up into a dust extractor. And when you open the door to pull your part off the end of the robot,

It the chamber is clean. So if I paid just for rough numbers, if I paid a hundred dollars for some cubic volume of the powder $90 of that is going to be into my part. And the other 10% goes into a dust collector. Correct? Wow. That’s amazing. That’s an amazing. A rate. So now you’re making this part in six minutes, which is definitely Lightspeed in our terms.

Are these usable parts or is this some. Blob on an end of a plate that we then have to do subtractive manufacturing to machine it. Yeah, it’s it, we really view ourselves as a competitor to casting. Okay. So there, there is some machining, but the whole post-processing is very simple. When the part comes off the machine.

We lay the substrate on a workbench and we hit it with a hammer and punch to the form, the sheet metal substrate. The park pops off, we throw it into a furnace to heat, treat it, and then it goes up on the CNC. Not typically. The machining time is pretty equivalent to the print time. So it’s a very fast process. And we’re building parts with densities of 99.5%.

Wow. So no voids.  I know a lot of times in our world of machining castings, we have to send them out for x-rays and we have to do all sorts of CT scans. And voids and porosity are huge issue, but you guys are 99.9. Yeah. You’re blasting metal powder particles against each other.

Wow. And then the density rate off the machine is 99.5%. Wow. That’s amazing now. Another thing you mentioned, I want to go back to is You knocked it with a hammer to get it off the substrate. And our SLS machine, we have to put it in a wire EDM. Yeah. And it’s a slow process. Cut it off.

How is it that your part can just come off with a hammer? While we’re building on a sheet metal substrate. You just have to deformed that substrate enough to where the part pops right off. So we’re we’re just hitting with a hammer and a punch. So what you’re avoiding is wired EME.

The part off the build plate. You’re avoiding. Recycling powder. There’s no supports to remove. It, it really simplified. The whole metal additive manufacturing process. And without that speed, you don’t get the economics. So it’s, we’re building. Large parts really fast and really affordable.

Yeah. So w we’ll break down the economics in a minute, because I, as I talked about in in the first show, My first exposure to an EOS machine was over a million dollar machine. It, the largest thing it could print at the time was around 10 by 12 cube. That was the one that was the largest one available.

And we, they were limited to three materials. And so I, we’ll talk about your product here in a minute, but I want to also focus. You just said that there’s no support structure. Every bit of printing that we’ve done involves support structure. And that’s one of the reasons metal might is a good fit for 3d printing because we also have all the subtractive machines, the five and six access.

So how can you get away with printing apart with no support structure? What how’s it hanging out there? We still have common design rules, guidelines that we follow. We can do 45 degree overhangs. But we’re working with the six axis robots. So we have many degrees of freedom as a result.

So we can avoid a lot of that supports. Ultimately we can. Print supports. And they would just be machined out later with the CNC. Wow. But we, we usually don’t, we don’t need to, you don’t have to machine it. The video you were just showing me and and we can send people here to the website to check it out.

I believe it’s. S P E number three D So they can check out the videos here, but the video you’re showing me as a boat propeller. It looks like it’s made out of an aluminum and the it’s coming through the rocket tube and it’s literally making it with no support structure. This is exactly what a casting would look like.

If somebody had a mold. And You’re saying that this product will be a usable product. Somebody can take this just like they would right out of a cat about mold with aluminum casting. Absolutely. And the whole idea with, for the people who can’t see the video, we’ve got a rocket nozzle inside of the chamber.

Fixtured at the bottom of the chamber, we’ve got a six axis robot. That’s holding the substrate, holding the part. And the whole idea with that. Is four. Automation. And we, our process is based on single piece flow. So we’re. Instead of batching parts and waiting for that batch to be done, then going on to the next stage, single piece flow is used a lot with Toyota productive.

Production systems. And so we’ll build apart, drop it off, build apart, drop it off, and it’ll keep going down the line. And what they found is that’s much more of a production of productive way to build parts. So at this point, you foresee this robotic arm dropping off the part. It just may grabbing another substrate and just starting the next part, correct. A human doesn’t have to load and unload this. Correct.

And so we’re talking 24 seven. It can run. As long as there’s electricity, it’s going. Yeah. And the important thing to understand with speed 3d is we’re building metal parts in minutes, as opposed to days or weeks. Taking this from concept to literally to the field. You have an engineer designing apart and any draws it up in CAD makes a model.

He can literally send this to the machine and we’re not waiting for. Mold makers or pattern makers or anything where we’re printing. At Mach three, making this part and. Within an hour, he could have it on a desk to show somebody. Yeah, Def definitely within an hour and a lot of cases within minutes.

We can run. We have flexible production. From one to 10,000 parts. It’s The great thing about it, really. And the key to our whole process is with the software. We have a very sophisticated software package that converts the STL file to the toolpath. And it allows you to simulate the part.

And do your trial and error. In the software prior to sending it to the machine. So when you do print the part, there’s no errors. So speed 3d. And I don’t know if we talked about this has been around for how long, how many years. Four years, four years now. They’ve put this whole package together.

And we’ll get into the cost of the entire package, but the intellectual property that they’re giving you is the Six axis robot and the, so did they write this software? Do they own it? Yep. Okay. So you’re not having to buy licenses from anybody or pay upgrades. So when you buy this complete package from speed 3d, you’re getting everything you need for this engineer to make this part in minutes.

That’s correct. As far as hardware goes, you’ve got a printer. An air compressor. In a dust extractor. I always equate it to a CNC. We expect the life out of these machines to be 10 plus years. We’re not going to come out with a new model every 18 months. With new optics or whatever, because we don’t use optics.

As new materials are developed. The software will be updated and you’ll be able to use those new materials. That’s incredible. Yeah. Now, So this is we’re on the topic of economics. Let’s get into this a little bit. I know you have some studies here. But typically what it costs to make a pattern and to create a casting.

And we’re focusing for the time of this conversation on the aluminum. Like you’re showing me the aluminum propeller blade here. W what does it cost to make something out of traditional casting and then, and where are we looking at with the speed 3d? Typically with die-casting you’re at about $10 per kilogram.

With sand casting, your 50 to a hundred dollars a kilogram we’re at. A hundred to $150 per kilogram. Okay. So in some cases matching the cost of a sand cast and other cases slightly more expensive, but now what’s our biggest saving. If there’s the cost value time, you can’t you can’t by the time 12, 12 to 14 weeks is what I’m told for an expedited pattern. Yup. And.

A pattern. Casting overseas. Overseas. And again, because of the environmental risks, that’s why a lot of castings are done overseas and your process is completely green. It’s completely green and we’ll be able to provide a better. Casting. With higher densities and you’d get, at best, you’re going to get 90% dense with a typical sand casting. We’re at 99.5%.

And now , since we’re at this part, talking about economics, these machines, like I said, the EOS machine is over a million dollars for a 10 by 12 volume. What would we be looking at to, to get one of these. You have a couple of models you showed me, right? We have two machines, the Lightspeed, which is approximately 13 inches in diameter. Maximum part size 13 inches in diameter by 12 inches tall.

Which is 350 millimeters by 300 millimeters tall. A maximum part weight, which is based on the robot, which is four kilograms or 8.8 pounds. But our big machine is the warp speed. That’s a thousand millimeters in diameter by 700 millimeters tall. So what does that in inches? 39 inches in diameter by 27 inches tall.

Wow. The maximum part size of 40 kilograms or 88 pounds. Wow. So we can build some really large parts. I just saw an image on the screen there of an engine block. Yeah. An engine block that would fit inside and you’re printing that. And under an hour, you’re putting that. No, that’s a longer, that’s 23 hours, 23 hours, three hours, but still that’s a complete.

I, and I don’t know a lot about patterns and casting, but I know that’s multiple slides and Gates and in a very complicated part to make that’s right. So if I wanted to prototype this new engine though, within a day, and You know what. We’ve actually we started this project part of the pandemic, so we simulated it.

We just haven’t run it yet. That’s incredible though. Again, for you talking about an engine, like you think of anything inside that size. 40, what was it? 46 by 29 39 inches, 40 by 27 inches tall. So we’re talking about steering, arms, knuckles. Things that now, again, we talked about aluminum. Are there other materials you can print out of? Yup. Yup. They.

Speed 3d started with copper. We’re really working on the softer materials. So copper aluminum, 60, 61 aluminum bronze, and three 16. L stainless. That’s material that just finished up the beta testing and will be available. The interesting thing about that. Is stainless a little harder. So they developed a new rocket nozzle for that.

That rocket nozzle will now be used on all our materials. Oh, wow. Changing out material may a, it becomes even easier. To change out material you dump. The powder hopper blog at the line, put in your new powder and you’re ready to go. You can do it with. Under an hour. So our SLS machine that we have to allocate two days. Yeah.

And we have to wear the the radioactive suit and the ventilator. And because some of that powder can be carcinogenic. You can open the door, wipe this thing down it load in a new, yeah. It’s not an inert environment and you don’t have to worry about. Powder getting

You don’t have to worry about getting your power getting

Breathing it. We’re not working in an art environment. You don’t have to worry about your powder. You don’t have to have a completely clean powder chamber, but our powder chamber is clean anyway because the remaining the dust that doesn’t get stuck to the substrate gets sucked up into the dust extractor. You don’t have to wipe it down with alcohol.

So it’s a very simple process. It’s so simple. That And most importantly robust is that we’ve taken it out into the field. During an expeditionary trial. In very harsh environment. In Australia and. Australian army soldiers built parts. On the system. They brought us CNC.

And finished parts while in the field. What’s really important to understand. Is our machine doesn’t need a perfectly level surface. It can stand up to the harsh environments of just shipping it. And what they did during this two week expedition is they offloaded the machine nine separate times. Got it up and running within an hour.

Wow. You wouldn’t be able to do that with any other type of equipment. Because of the optics. So with our machine, we’re not using a NERC gas. We’re using compressed air. So you can, it. We do a lot of work with defense around the world as a result of this. Yeah. And you talk about the need, right? So for the military, but you got to get those trucks back up and running and get back on the road. So it’s all about getting them up and running and engaging them, getting them back to home base.

Now talk about it. I interrupted you a little bit. You were talking about the process. So you’ve got the material going through at Mach three, putting it on the six axis robot, making this product. And then you said something about going into a furnace. So what w you have to have this second. The second piece of equipment, you have to have a furnace there. How does that work?

You have to have a furnace. We’re not the benefit with our technologies. That we’re very repeatable because we’re not melting powder. So we don’t have the thermal stresses that you’d normally see in metal editor manufacturing. We do have some painting stress. Or complexual stress. So that’s why we heat treat it to increase the ductility of the part so that it can then be machine.

Gotcha. And earlier before we started. Recording you and I were talking and you said there’s even more materials in a beta. Phase right there. Yeah there, there is more materials. Our core materials are the copper. Aluminum and aluminum 60, 61 aluminum bronze and three 16 stainless. We’ve done brass.

81 50 copper tunc standing copper coated Chrome. We’ve got about 10 additional materials in R and D and we’re working, we’re doing a lot of work with universities right now, so we expect. The materials list to grow exponentially over the next six to 12 months. Yeah, that’d be amazing because you and I both come from a background working with the aerospace world with the titanium and the inconels and things they want. So I know that they’re going to be watching very closely

And now the space race is on with a couple of private space companies that we don’t have to name, but everyone knows who they are. And they’re wanting to make things out of these products. So it’ll be interesting to see how some of that. Can go in the lab and how some of that can get made.

But I think, in general, this concept of cold printing, compressed air while it’s not cold because you’re heating it up, but you’re taking. Compressed air shooting in a Mach three making parts in minutes. And then going right to the production line. In some cases, as you would normally machine a casting that comes out of a housing, you would normally be, would machine yours as well. In other cases, if it’s a finished as that the parts you were just showing me what this military.

Some of those look basically finished maybe a couple bores needed to be cleaned up, but nothing on the outside. Needed to be touched. So yeah the outer surface, when the perk comes off the machine, it looks like a casting and you’re only going to machine the areas, the mating surfaces the holes.

Only is surfaces that matter. Like I said the machining time is typically. It’s pretty equivalent to the print time and the print times really fast. So that’s amazing. And you did say the prices, right?

The Lightspeed, which is the three 50 millimeter in diameter by 300 millimeters tall. Is list price is 560,000. The warp speed, which is the big machine and thousand millimeters in diameter by 700 millimeters tall is 740,000 list price. Wow. So again,  very competitive compared to some of these SLS machines.

In our our 10 by 12 machine retail over 800,000. Yeah. I think it’s important to understand too, that it’s repeatable. It’s fast and it’s repeatable because we’re not molding powder. So we don’t have to worry about parts peeling off the support. The build plate.

B because we don’t have those thermal stresses. And we’re only using the material required to build the part. So if you’re building a large part, In any other metal process you’re loading up that chamber full of it could be up to a hundred thousand dollars worth of material, right? We’re using the material that’s required to both apart.

And plus in our FDM processes that we use a metal might be. There’s a bonding agent. There’s a filler agent that we have to put in a wash and get rid of. And then we go into syndrome. So you don’t have any of that. Your materials a hundred percent what the part needs to be. That’s pretty clean. That’s pretty amazing.

We were talking about replaceable parts on your machine. You do did talk about the rocket tube wearing out in time. Our SLS machine, we actually heard a story from another shop, similar to ours that somehow the laser went bad and it was between a hundred and $150,000 to get this laser replaced a rebuilt.

So there’s some concerns, right? On some of these expensive pieces of equipment about what’s going to wear out, what’s going to stop working. What’s the concerns on yours, or what do you expect to be worn out over the course of this 10 years? It typically with cold spray ad or cold spray.

The machine. When there’s only a handful of companies out there doing cold spray and in the world. And they’re using it for repair and coding, and they’re only running it for a short amount of time. Okay. So there, when I talked to those people, their big concern is how do you keep your nozzle from clogging?

We run we’re building parts. So our machines run longer than what they do. So our nozzles are designed to run without maintenance for a thousand hours. Oh, we usually get between a thousand. And 2000 hours. The nozzles are relatively inexpensive, $1,500 for a nozzle. Wow. And do you foresee anything else wearing out like that?

This robot. I know I talked to him. That’s pretty low maintenance. You might have some maintenance on a air compressor. You would change in changing over materials. You’d clean out your Your a dust extractor. It’s a wet dust extractor. But that’s pretty much it’s a very, it’s a very simple.

An easy to use operation. Don’t we’re not required. You’re not having PhDs run this machine. Wow. That’s good for guys like me because I’m not a PhD. Yeah. I wanted to be sensitive of time. We promised people to keep these shows around a half hour. As we’re wrapping up, we definitely want to give our listeners a chance to get ahold of you and get a look at these videos. So I’ll ask you to tell us that. Is there any other final things you want to tell us about this machine?

For one, I would be curious. Are these things available? I know we’re just working on them, but if I said right now, want one of these things. How long am I waiting to get one? You’re going to wait about 12 to 16 weeks. Okay. Our headquarters is in Melbourne, Australia, and that’s where the machines are built.

Okay. They’re available to we’ve got a couple of machines available to ship. Right now, actually. But typically 12 to 14 weeks. Okay. So as long as it takes to get across the pond, as they would, yeah. I think Australia is still the bond and might be a little bit.

Yeah, bigger pond. Excellent. So it’s not something where that are years off.  This is happening now. No. We’ve got several machine. Probably got 20 machines around the world right now. Okay. And we’ll double that this year, despite the pandemic. Wow. That’s incredible.

And so give our listeners a way to get ahold of you if they want it. Yeah. You can get ahold of me through LinkedIn. Paul hollow body. And, or if you want to go to our website speed, and that’s S P E three D one word. Dot com. And we’ve got a number really. Fascinating videos on YouTube on our YouTube channel.

Fantastic. Yeah, I’m excited. And when I heard when I heard about this printing at Mach three, I couldn’t help, but think about, this year we keep being promised the top gun, two movies coming out. And of course growing up in the eighties, I was a big top gun fan. Wanting to be a fighter pilot. To me, I think of this machine is the top gun of the 3d print world. Cause you’re traveling that fast. So yeah, that’s pretty exciting.

Thanks, Paul. I appreciate you joining us. And to this last part, I want you to stick in here with me. We always talk about current events is what we used to call them in school. So I still call them that today. I always look up a couple of stories of what’s going on in, in our additive manufacturing world.

And how are we using 3d printing? As you and I both know where we’re coming from, the manufacturing background. So we use it for tools and parts to make vehicles and to make things, but. We’ve talked in previous shows how people are using it to 3d print food and 3d print housing. So I found two articles here that I found quite interesting.

Current Events:

AM Ventures has announced the launch of a €100 million fund to support 3D printing’s most promising start-ups. 

By joining forces with serial investors KGAL, AM Ventures’ majority shareholders and EOS owners the Langer family, are now able to offer the first-ever VC fund that’s dedicated to industrial 3D printing. KGAL’s input brings the total raised to 50% of AM Ventures’ target, and from spring 2022, the capital will be reinvested in start-ups that are developing their own hardware, software, materials or applications. 

“After six years of successfully investing in AM-based start-up companies, we decided to jointly take our business to the next level,” said the fund’s Founding Partner Dr. Hans Langer. “This step is a massive opportunity for all AM start-ups around the world, and will help to further accelerate the adoption of AM.”

The first one. Applies to you guys as being a fairly new, four year old. A startup company. But I’ve I’ve got a link here on the website. You guys can find it, but it’s a M ventures. Announces the launch of a hundred million dollar fund to support 3d printing to the most promising startups.

By joining forces with serial investors. K G a L a M ventures, majority shareholder, and E O S owner. The Langer family are now able. To offer the first ever VC fund dedicated to industrial 3d printing. So they talk about the Langer family is the EOS. Founder. The machine. I mentioned those first one I saw 20 years ago.

And they believe in additive manufacturing for the future and they believe it’s the way to go. So they’ve put together this quite large fund, a hundred million dollars to help any startup. Interested in doing it. And the quote here from Dr. Langer. The founder says after six years of successfully investing in am based startup companies, we decided to jointly take our businesses to the next level.

Says, founding partner, Dr. Hans Langer. This step is a massive opportunity for all am startups around the world and it’ll help further accelerate. The adoption of additive manufacturing. Yeah, it sounds like a similar to what speed 3d is a four year startup. And and maybe you’re maybe your founders want to call Mr. Langer here and see if they.

They want to invest. But that’s great to see that it’s happening. No, you and I are big proponents of 3d printing and we’re hoping more people. Can jump on the scene with it.

And then the last one I say this is now coming full circle. My father who was said to be dyslexic. Envisioned that 3d printing would be our future. And there’s a company now using additive manufacturing to make glasses for dyslexic children. Using an HP. M J F multi-jet fusion machine.

3d printed glasses are being made for dyslexic children. By as a startup company.

By, as a startup company developed by a French optician. Name. Oh, French name here. At toll loss. Up traditions, I dunno. I’m not French. So I can’t say that one again. The links on our website he’s deployed the HP. MJF 3d printing technology to produce the frames. For the Lexi lens smart glasses, which is designed to make reading easier for dyslexic children.

Glasses are electronic. They have acted. And tinted lenses, which filter out the mere images and causes the reading difficulties activated by pressing a button on a frame. The Lexi lens weighs just 35 grams printed entirely using the MJF by the French 3d print service Bureau that E R P R O. Before being assembled together with these lenses and other components. So that’s pretty interesting. I had dyslexic children.

HP MJF delivers 3D printed glasses to dyslexic children

Abeye, a start-up company developed by French opticians Atol les Opticiens, has deployed HP’s Multi Jet Fusion (MJF) 3D printing technology to produce the frames for its Lexilens smart glasses, which are designed to make reading easier for dyslexic children. 

The glasses are electronic and have acted and tinted lenses which filter out the mirror images that cause reading difficulties, activated by pressing a button on the frame. The Lexilens frame weighs just 35g and is printed entirely using MJF by French 3D printing service bureau Erpro before being assembled together with the lenses and other components.

“The manufacturing process for Lexilens 3D printed glasses is remarkable as it is the first printed multi-component product with such complex assembly,” said Emilio Juárez, EMEA Sales Director, HP 3D Multi Jet Fusion Business. “As there are no less than nine components, our partner Erpro’s expertise was extremely important in the context of developing multi-component products where assembly groups managed without comprising the quality of the final product.” 

It’s fascinating. Yeah, I think it’s fantastic. And we can find any of the markets that additive manufacturing is bringing and of course, with your product The one of the delays right now, we thought printing things in one to two days was amazing. Using our FDM processes, six minutes is certainly.

Certainly a lot faster to wait. Again, we appreciate you joining us today. Thanks, Tom. Anytime I’d love to Love to come back at some point. you are the first expert to talk about printing something at Lightspeed. Almost Lightspeed three times. Speed of sound. And we’ll definitely have you on for future shows. Thanks, Paul. Great. Thanks again.
