I like that dude, he seems like really a nice guy. I wish them great success with their glass printing journey

[@nickbirbilis9193]

Legend comment 🫶 🙏🏾

[@ZappyOh]

This should be done with steel-wire as filament ... Carbon steel melts around 1500C.

[@TheSpooniest]

There's a viscosity problem there, not necessarily all that different from glass (which they discuss in the video) but I'm not sure it's been cracked yet. You don't want to print materials completely molten, because they won't hold their shape. It's the opposite temperature problem from casting (where you want materials to be as liquid as possible, so that they'll flow into details in the mold), but you're working with narrower ranges. I'm not sure this has been completely solved for metals just yet, though a machine like this could be a good starting point.

[@roderik1990]

Also the problem that crystalline solids (like steel) have much more sharp transitions between their solid and molten states, unlike the smooth transition from solid to viscous/rubbery that occurs in materials with a glass transition.

[@galfisk]

The big advantage to metal is that it's electrically conductive, so arc welding techniques can produce a nice controlled puddle of molten metal, without needing to heat up an entire nozzle.

[@MapleGlassPrinting]

Great thoughts! Indeed, exploring metals seems to be an avenue worth exploring, the viscosity softening in glass vs melting point of metals is a difference that needs addressing but we like to say anythings possible!

[@BelviGER]

​@roderik1990 same reason there is basically no bottle pet filament despite it being a great material for finished prints You need to have the cooling perfectly on point so it doesn't crystlize in the print but also doesn't freeze your nozzle

[@soundsofglasswork6283]

This is definitely cool as a glassblower, but I think this is limited in how it's very art restricted, and I have zero idea how that would work with striking colors (What makes pipes have those crazy color transitioning and holographic colors) This isn't replacing lampworkers or glassblowers it's just another option in the toolkit for another niche application, which we have dozens of. It's what I love about glassblowing.

[@soundsofglasswork6283]

Also, there is a 3-D printer that does make solid industrial parts for glass by 3-D printing a part and chemically turning the product into glass. Bunch of cool stuff.

[@MapleGlassPrinting]

@@soundsofglasswork6283 Great points! There are limitations to all technologies, however, what we love about this technology is that you don't need years of glass blowing experience to get involved with glass production, just a dream and access 😊

[@beilkster]

Just curious, could glass blowers reheat a 3d printed glass piece and then work it the way they want? Would it change the possible shapes and designs available?

[@AaronHendu]

Think about scale...tiny bits incorporating some type of function, whether it be mechanical or whatever...that could never be blown manually. Like valving, etc. Could use those smaller printed glass parts into larger manually crafted pieces. So much potential, imo.

[@tsuobachi]

I think it's worth mentioning that the main purpose according to Maple Glass is to use recycled glass. If we can upcycle plastic and glass via 3d printing instead of sending it to landfills, it's only a good thing for society. There will now be a financial motivation to take all of that waste and do something with it.

[@Dacraun]

Retrospectively, yeah why COULDN'T we 3d print glass? But having the idea and executing it is amazing. I'm impressed.

[@GIRGHGH]

It started out mostly with hobbyists, and hobbyists can't get a 1000 degree printer that needs custom parts that easily. It's mainly a price thing

This is such an incredible printing machine even as a working concept, but I'd LOVE to see more in-depth coverage on that hot end and how they get it to survive in its operating environment. The website was rather spartan on details. If it proves to be a solid solution, glass is just the beginning of high temp materials that could be run through this.

[@3DPrintingNerd]

My goal is to find my way to Australia and see first hand how it's made, and dive deep on the details!

[@MapleGlassPrinting]

Indeed glass is the beginning of what can go through this machine! Happy to share more details on the design in time, it is a special part of our machine 😉 There should be some older videos on our KZbin channel "Glass 3D Printing Introduction" would have some small clips showing the heated block, if you'd like to check it out.

[@WaterspoutsOfTheDeep]

I was expecting this to be glass power in a binder that would be 3D printed then put in a furnace to melt together. Didn't expect it to actually be melting and forming the glass in the machine, pretty cool.

[@jeremiahembs5343]

Very cool. I'm sure the glass could be polished or sand blasted and re-dipped in liquid glass for different finishes.

[@MapleGlassPrinting]

Absolutely, post processing is a big options, especially in glass as the part can be reworked in heaps of different ways

[@vedritmathias9193]

Ok, that was cool

[@dustin860]

Curious, is there a reason there's not a torch heating the previous layer before the extruder deposits more material? That'd likely result in smoother, more precise prints.

[@nickbirbilis9193]

Great q! I don't believe its needed as the process is in a heated chamber and the thermal conditions can be well controlled (unlike with a torch).

[@dustin860]

@@nickbirbilis9193 I get where you're head is at there. My thinking is, if the kiln is heated to the extent that the previous layer is hot enough to be fully welded to the new layer, the previous would likely puddle and flatten out. With a little hydrogen torch with a precision valve, that could be avoided. Heck, they could also add a paddle to smooth out the weld while its hot. Super cool technology!

[@BenKiefer]

I want to say, as someone who is just interested in 3d printing but has no experience, I really appreciate you showing definitions on the screen for the common terms being used.

[@ScientificGlassblowing]

Very exciting technology!

[@MapleGlassPrinting]

Thank you!

[@michaelveneziano118]

Very cool! But i have one question: why fdm instead of the powder kind of 3d prints? Is it because the laser would have been deflected and/or the accuracy would be lower?

[@aryoncoolindustries6615]

[@rogueyun9613]

I wonder what the next evolution of this will be. This is exciting.

[@sportsmad3278]

Sounds like the best tech in this invention is that heater the output is insane

[@anon_y_mousse]

This is pretty cool. Does their printer do the annealing too? What's the longest bridge they can do? Are the prints waterproof? How easy is it to smooth the prints and hopefully not melt them into a puddle of glass? And finally, if you smooth a print, will it be more optically clear?

[@MapleGlassPrinting]

Thank you! The printer anneals the part during production, the longest bridge we have done is around 40mm, however, we haven't pushed bridging limits yet (more to come!). The glass we use is waterproof. We have smoothed parts by teaming up with glass artists / blowers, with some skill its possible! Yes it will be more optically clear.

[@anon_y_mousse]

@@MapleGlassPrinting That's a great bridge length. Even though I'd likely never need one that long, I would be quite interested in how far you can push it.

[@StevenIngram]

These guys are headed towards making lava printers. LOL Prints molten rock. :D

[@MapleGlassPrinting]

Love that idea!! haha

[@StevenIngram]

​@@MapleGlassPrintingWell, if you go down that road - I'm sure its something the space industry would definitely want. Imagine would it would mean for building habitations on the moon or mars if you could just scoop up rock and print it. ;)

[@MapleGlassPrinting]

[@ObGoRat]

@@StevenIngram Everything which does not include lifting ginormous loads into space for building material is a potentially good idea :) Maybe it would be possible to compress moon dust and encase it into building blocks made of additively manufactured glass/mineral shells.

[@tiki-ed5573]

Incredible! Can you smooth the print? Mayne with a blow torch or more kiln time?

[@MapleGlassPrinting]

Thank you! Absolutely we can smooth the prints! Using blow torch is the easiest way however you have to ensure geometry doesn't change too much. You can also use moulds and fill the gap with glass powder and remelt (however this takes time and effort). A goal of ours is to print crystal clear parts straight in the print step.

[@rjds1800]

Working out the glass point of glass.

[@AmaroqStarwind]

They should probably run some of the glass through a mass spectrometer. If they're recycling any glass which happens to have heavy metals in it, it'd be a good idea for them to know beforehand so that they can take appropriate precautions. Radioactive glass is also a thing.

[@quakxy_dukx]

The thing I find most interesting is that their goal seems to be to make glass 3D printing available to the average consumer

[@FranklyPeetoons]

Well, a glass baby yoda certainly wouldn't melt on my dashboard in the summer. but if I have a wreck the glass baby yoda might shatter and shower me with jagged fragments. Every new tech brings new hazards, i suppose

[@MapleGlassPrinting]

Absolutely, safety is key!

[@phizicks]

that's pretty sick, and of course he's an aussie.

[@emmettpickerel5016]

Fantastic! I wonder... do the printed parts need to be slowly cooled as you would with blown glass? If not... then that very much speeds up the process!

[@MapleGlassPrinting]

Great question! We cool the parts very fast compared to traditional manufacturing. This is because we anneal the part while its printing, so once printing finishes the entire part is already at annealing temperature (~500 degrees C for the glass we use). In other processes the entire part is typically at working temperature (say ~1100 C for glass blowing). Typically, within an hour or two we can remove the part from the print chamber.

[@TECsta76]

In retrospect this process should benefit greatly alongside an oven curing process...

[@MapleGlassPrinting]

You mean post heat treating the glass? Indeed, that is a possibility. Our parts, at this stage, are used straight out of the print chamber after they have cooled.

[@CLIPsinester]

So i can print a new bong now? Nic3

[@kingarthurthe5th]

Could this print with some form of Zirconia glass (or precursor paste)? Also, would it be possible to print glass to then chemically strengthen it?(like gorilla glass) Also, would it be possible to make vacuum capable parts/chambers?

[@MapleGlassPrinting]

We love to say that anything is possible! I don't see why other materials such as paste's couldn't be printed (provided the temperature etc... is set correctly). Printing in a vacuum is interesting. We print inside of a furnace at the moment and I perhaps with a special furnaces they could be vacuum tight to introduce a vacuum atmosphere.

[@hellawacked]

From a glassblower that can only be made by a 3d printer object can be made without. It’s a technique called crocheting

[@MapleGlassPrinting]

[@3dPrintingMillennial]

I bet you could make a helluva good bullet proof vest with this

[@kamhaq]

Can we use glass powder that might keep the viscosity same? Or can use lesser to melt on place. Just a thought

[@MapleGlassPrinting]

We have produced filament from powders, cullet, billets etc... but our current machine requires filament at this stage 😀

[@Imaboss8ball]

I wonder if they could use glass thin like fiberoptic. That way they could use a roll pf glass fiber.

[@MapleGlassPrinting]

That would be great! I'm sure with some change in the extruder design we could get the nozzle to use a fiber (or flexible glass filament) as oppose to straight rods.

[@brydenquirk1176]

[@wreckingball8881]

[@napalmholocaust9093]

Cullet glass can be pretty dangerous. Glass factories have the pile shielded. It didn't go through equalization so it is full of pent-up stress. Some of it explodes just sitting there. My ex's dad had his lunch tote shredded by a chunk he was liberating from work. Cut his side too, but not seriously.

[@jamilandretorres]

Yo bongs are gonna get wild in ten years.

[@ObGoRat]

Very cool and sustainable. Depends on the energy source (renewable preferrably) and the efficiency of melting and remelting the glass after sorting, cleaning and so on, but this could find really creative applications.

[@MapleGlassPrinting]

Thank you! Indeed, the context in which the technology is used is very important! As a note, the cleaning process that we use for our glass waste from the glass blowing studio is a quick wipe with a cloth to remove dust 😃

[@ObGoRat]

@@MapleGlassPrinting Thank you for the added information, I appreciate it. I cannot estimate how large that grade of glass waste is as a ressource or whether this glass would otherwise already be used for other applications, but it looks promising :). I'm very surprised how easily you seem to achieve adequate cooling since I thought that glass which is cooled too fast could retain tensions which could make it shatter. But my knowledge about glass is on a grade school level at best and you seem have figured solutions out already. Would be cool to see your technology in the future for very specific applications for example - where one needs a complex part made out of a chemically resistent and inert material and at the same time could not be manufactured with molds or glass blowing.

[@MapleGlassPrinting]

​@@ObGoRatThank you for the great questions! Being able to anneal the glass while printing is the key. Further, as we 3D print the shape we can decide to use thinner walls making cooldown much faster. Stay tuned for more demonstrations on technical applications, its a matter of time!

[@ObGoRat]

@@MapleGlassPrinting Thank you for the insight. So I guess you could e.g. print a thin perimeter which cools down faster, print a parallel thin perimeter touching the first and anneal them both to have the advantages of both rapid cooling and thicker line widths?

[@MapleGlassPrinting]

@@ObGoRat Absolutely, and that is just the beginning! Unlocking new geometries means that we can do so many new cool things with glass!

[@frosandrockets]

[@gamedevai]

After seeing this clip and understanding the importance of heat control over the head nozzle, my idea is, if it was never tried before, is to make an all glass head extruder, seeing glass can dissipate heat faster for more control in addition use a hot laser hitting the filament through the transparent class extruder head. Since I dont have a 3D printer this idea is only theoretical. Do you think that this idea would have any benefits or could work cheers Perry

[@MapleGlassPrinting]

Wow! Indeed, the glass 3D printing community is getting bigger and some have tried and do print small scale glass parts with a glass fibre / laser method.

[@MapleGlassPrinting]

Great question! Glass, like other materials, will break at the weakest point. Because it is very brittle, however, the glass will break very cleanly meaning we can even use support material (as the introduced defect will provide a breaking point for the glass). The string of glass is usually a little flexible (or very flexible if very thin) so can typically be broken off by pressing a pencil against it. 😃

Moving forward, we are building a large scale version of our 3D printer, which could introduce glass as a structural material, as well as large scale facades etc...
