Open-Source SLS 3D Printer: Project OpenFuse

[@3DPrintingNerd]

FREAKING AMAZING

[@onewayfe4r]

Heyy

[@truelyscrumptious]

I'm so happy to stumble across this. My husband is a chocolatier and we got into 3D printing several years ago to design our own chocolate moulds. I've become fairly well versed in FDM and SLA so I guess SLS was an inevitable next-step. I always did enjoy doing sugar work.

[@handsofrhythm3415]

Nice work Luke. You are going to get the collaboration you are looking for and this project is going to grow. In 5 years I'm going be telling people that I was here, at this point: Luke Cunningham looking up from his laptop notes, realizing the potential of what and he was starting.......... and he was smiling. I am strapped in for the ride young man. I wish you all the best. Thank you.

This has a bright future. I reckon one day SLS printers will be as common as FFF.

[@MakingwithLuke]

Thanks, I think the future for this is bright as well. I personally don't see SLS being as common as FDM, but hopefully more common than they currently are.

[@howtoguy17]

I hope this blows up, because it blew my mind

[@BreakingTaps]

Very cool! I was playing around with sintering silicon carbide on my fiber laser, and starting to CAD out the design for a proper SLS system (feed/print pistons, recoater, etc). But one of my viewers mentioned your channel and this looks much better! Looking forward to hacking on this design, looks like you've done a great job. Out of curiosity, is the recoater a blade-style, or roller?

[@MakingwithLuke]

Hey I just saw you in the discord and thought to check youtube since I thought I had seen your channel before, turns out I was right haha. Yeah, that's awesome to hear. What have you found out about silicon carbide sintering? that is seriously cool. I think you may have already found this out, but I just changed the design to use a recoater blade instead of a roller, but the system is very modular in case I wan to switch in the future. Excited to have you in the group and to your some of your work in the future! Lastly, I've realized that I'm subbed to your channel on my main viewing account, you've done some really neat stuff.

[@luxnox9303]

Have you tried printing in powered sugar? If you put the sugar you have into a blender or food processor is easy to make large volumes of it.

[@MakingwithLuke]

I have, and I had issues with it because of its small size, but I'm making smaller granules doing what you mentioned. A set of sieves really help to classify the sizes as well

Great to hear that! If you want, I put a survey for those interested in purchase in the description. Castor Sugar has been discussed in the discord, and is better than granulated sugar, though grinding smaller sugar from granules seems to be better because of the smaller and more controlled grain size.

[@MakingwithLuke]

Ayyyy! Thanks man! I have yet to do some more tests with pla powder, as the last laser tube was too powerful and would vaporize material instead of sintering/melting it. I'll have to do some more tests really soon to make it work no that I have a less powerful laser. Yeah, this video felt like it took a few decades to make, so I'm glad you like it!

[@linkreincarnate9402]

@@MakingwithLuke You cant turn the power level on the laser down? Most laser cutters that I've seen have variable output power levels.

[@MakingwithLuke]

@@linkreincarnate9402 Yes, I did actually. The problem is that laser tubes have a minimum amount of power you can send for the tube to activate. Can't go from 0-100, more like 25-85 I was at the very bottom limit of what the tube could be fired at, and powder was still being vaporized. The 10w tube has a much lower power "floor", so I can drive it at lower power settings than the 40w tube.

Woah, i was about to say that you should contact 3D Printing Nerd, but as i see, he was already here.

[@multi-mason]

So where are you at on the fully assembled or kit based packages? I want one! Maybe this wouldn’t be too difficult: Metal powder (not specialized, but common industrial variety) mixed with a binder powder (maybe wax, or even sugar). The printed piece could then be fired in a furnace to burn off the binder material and fuse the metal powder. Prior to printing, the model would need to be scaled up in order to compensate for shrinkage from binder material loss and fusing of metal powder during firing. The required scaling could be predicted from an initial small test piece, for any given metal/binder mixture, while furnace temperatures and firing times would be based on the types of metal and binder used. A possible problem might be ash mixed into the finished metal piece. Actually, I suspect that may not really even be an issue… If it is though, then I’m sure it could be addressed with the right binder material and/or a pressurized furnace. Some metals would require very high temps for this to work. Some metals though, such as aluminum, would not have prohibitive furnace temp requirements. So buying or building a furnace for those lower temp metals would not be too expensive or difficult, and just aluminum would open up so much potential. While higher temp metals would probably require a fairly expensive pressure furnace, which would still probably leave the printer/furnace combo proved far less than pretty much any other metal 3D printer available.

[@generalawareness101]

Basically we have a core XY K40 Laser with a scraper? I absolutely love it. I take it the hardest part would be that scraper that has to deposit another (EXTREMELY FINE) layer of material. Even on the old 100k usd powder machines I never understood how it never messed up a layer by not making sure the material was actually spread out.

[@DavidLee-od3bu]

This is really cool. Can't wait for you to release updates about this project. I would be interested in buying a kit if you were to produce them.

[@kerryai]

Nice work done here. Looking forward for your update.

[@kerryai]

BTW, it seems you were using granulated sugar. Have you think about using powder sugar? I guess the finer sugar gives you better dimensional accuracy of your prints. Since larger particles require longer time for heat conduction. This might impede fusion in between large particles and cause inaccuracy. Once again, I really like your work of proofing concept.

[@jameslibby5215]

would you get a better result with powder sugar? I'd be curious to see that. subbed.

[@justinjohnson9627]

He mentioned that it is possible to adjust the grain size of sugar in a blender. Having seen other people do that with salt, I think sugar might be more amenable to it. Then again, you could just buy powdered sugar... but that has cornstarch etc.

[@rvisani]

This is a super exciting project. I'm looking forward to see how it develops. There was a very similar SLS printer called the Candyfab which printed in sugar. If you haven't seen it, you may want to check it out for ideas. Thanks and good luck!

[@MakingwithLuke]

Thanks! I'm very excited it about it as well. I am aware of the candyfab, and have since been in touch with EMSL about the project. Candy fab is a classic reprap project the informed me of the viablility of sugar as an sls powder.

I'd be curious to see the results when using a much finer powdered sugar instead of the larger granules of regular white sugar. Would love a reasonably priced kit, but would want to make sure it actually produced quality prints first which you can't tell based on the regular sugar prints.

[@GrafTrahula]

What if you use printer toner as material? It's like 8 microns grain and made of PP and easy to melt even with diode laser

[@Dsk001]

This looks awesome. I would suggest powered sugar for future tests

[@MakingwithLuke]

Thanks for the suggestion. I've actually tried powdered sugar, and it seemed to be too fine actually. For some reason (I don't know the exact physics behind it) when powdered sugar is melted, it balls up instead of laying in a consistent pattern. A mixture of powdered sugar and granulated sugar worked quite well, however, and I have high hopes for the 50-100 micron powder I will be making to test soon. Small enough to give great resolution, but not to ball up

[@sylvainmartin73]

@@MakingwithLuke powdered sugar also contains corn starch to prevent caking. might try grinding the pure sugar with a coffee grinder or something like that. like the salt annealing with pla we're seeing lately kzbin.info/www/bejne/pIOve2evoayHfMU

[@MakingwithLuke]

@@sylvainmartin73 Great point! I knew powdered sugar had cornstarch as an ingredient, but may have underestimated it's role in the balling up. I assumed the size was the issue, as things like surface tension start to play a role with lower mass particles. I'm currently grinding and sieving my own sugar powder, and am working to make it much smaller. I think the results will be great

[@hectororestes2752]

Excelent! so next step is just using a stronger laser, making it airtight, fill it with inert gas and you have a metal printer? awesome. BTW have you tried using finer sugar? there is powder sugar readily availible at supermarkets at least in my country.

[@MakingwithLuke]

Ah, there's a lot more to a metal printer than that, but I like how you think. Thank you, and that's a good idea. in fact, I've already done some experiments with fine sugar and found that there is a nice sweet spot for proper powder printing. If its too small, like confectioners sugar, the melt pool turns into a ball before hardening. If the powder is too big, then resolution suffers.

[@hectororestes2752]

@@MakingwithLuke I wonder If the sugar print could work for lost casting with molten aluminum. It could work either by straight melting the sugar upon contact with the molten metal. Or, solidifying plaster around the sugar figure, and then disolving it with water, somehow not altering the plaster around it. Hmmm your work makes one wonder many posibilites for useful prints.

[@ericlotze7724]

On the note of simplicity this esentially a CO2 Laser Table, with a Powder Bed Setup Below. "Complex" but nothing more complex than one of those SUPER common K40 Laser Tables I would think.

[@ericlotze7724]

MAYBE getting the powder level, or grain size and all that, but these are moreso issues with the process (like designing FOR FDM or Injection Mold Design) rather than the machine itself.

[@ericlotze7724]

And if you wanted to make it even MORE simple you could use some lower precision/speed gantry like the Ender 3, or even the OSEs "Open Source Universal Axis": wiki.opensourceecology.org/wiki/Universal_CNC_Axis

[@ericlotze7724]

Also perhaps some sort of method for "bottomless laser tables" like "Full Spectrum Laser" does (but maybe just bring an angle grinder to a K40 ;) ) so all that is needed are those powder pistons?

[@uthzx]

Great results so far!! I'll be following for sure! Id love to adapt a powder box to my fiber laser

[@MakingwithLuke]

Thanks, I'm glad you're interested! I would recommend against using polymers with a fiber laser, however. The wavelength is in the near/shortwave infrared spectrum, which will simply be reflected off the powders. It is particularly dangerous as well, because it is invisible to our blink reflex, and will directly damage the retina, not being stopped by the cornea or acrylic. The high power is also concerning. I would strongly recommend building a machine with a lower power co2 tube, which is what this machine uses. The wavelength is absorbed by plastics very well, and is less dangerous than a fiber laser.

[@uthzx]

Oh i know, I plan to use metal powder & specific polymers under an inert atmosphere. I run & have built a handful of large co2 machines & also have a fiber so im very familiar with the wavelength requirements for specific materials. Good looking out though 👌 I wanted to used the fiber since its the only galvo machine that I have on hand, it works quite well on some polymers & not at all on others. The co2 machine's I run are classic XY Cartesian style so quite slow comparatively.

[@MakingwithLuke]

@@uthzx Awesome to hear your knowledge on this! I thought better to over explain than be sorry I didn't :). What is the wattage of your fiber laser? I assume it is the 1064-1080nm type? Have you joined the discord? I'd love to have you getting your thoughts out there.

[@SidekickElements]

Did you ever get around to making a toolchanger for the SKGO? Could be cool to make a toolchanger for this printer too. Maybe change to a liquid jet tool (inkjet or other). Although, I guess you could just incorporate that directly into the main print head since both tools should be non contact.

[@drewcraycer3002]

Nice video amazing work. Plus you kinda look like micheal reeves with the hair and glasses but I’m probably wrong

[@MAYERMAKES]

very big R& D effort, congrats! I like to know more about how you determined to use a Co2 laser, which is a great choice but is there a big difference to diode lasers? maybe in what materials work for this system.

[@tunckuyel]

i wonder that it can print with sugar and can carbonize sugar. so can it print carbon parts?

[@Triad3DStudio]

Really cool! Do you think by adding "the perfect" ratio of powdered sugar to "the perfect" ratio of the course sugar you're using now could result in a smoother finished part?

[@MakingwithLuke]

Yes, and actually the pros use what is called a bimodal particle distribution, or a mix of two different particle sizes, but they do it for different reasons. I have personally tried mixing granules and powdered sugar and had great results very early on, so I will be pursuing it further in the future. It helps with a number of powder physics issues besides smoothing as well.

[@urjnlegend]

@@MakingwithLuke you need different shaped granules, for the geometry to "fit" together. Different sizes is also good don't get me wrong. Also, a vibrator instead of a particle "patter" to arrange the "molecules" into their optimum resting state

[@marcelh2341]

Where did you buy the 10w co2 tube? Only find attractive offers down to about 40w.

[@MakingwithLuke]

I found the 10w tube on ebay, but Cederb (in discord) found that the same vendor sells them slightly cheaper on aliexpress. They are more expensive than 40w tubes, but 40w tubes are too powerful from what I've found. I've designed the machine to accept anything up to the 40w length, so if I can get one to work in the future it would be an easy swap.

[@marcelh2341]

Have you considered another laser type? CO2 lasers have a very bad beam shape. You need rather expensive optical stuff to shape the beam for fine and good quality prints. Sinterit Lisa (pro) uses a 808nm 5W IR-Laser. You can shape the beam with an amorphous prism pair. Only downside is, you can only print dark materials otherwise you will encounter absorption issue's . Also consider a heater chamber an heated powder bed. When you heat the material a few degrees below the glass transition temperature you can print faster and don't need a lot of laser power. You will need good temperature control.

[@MakingwithLuke]

I have considered the near IR lasers like the one used in the Sinterit and Sintratec machines, though I think only being able to print dark materials quite limiting. The optics to control the C02 beam are not terribly expensive, and I've found no issues with the beam quality of the lasers I've used. I am keeping the design open in case I (or others) want to use a diode type laser in the future. I think the low cost and upkeep of a diode laser is very attractive. I have also designed the next version to include silicone chamber heaters and ceramic IR heaters , so I can heat the materials to near melting temperature and sinter like the existing printers on the market do.

[@marcelh2341]

@@MakingwithLuke when can we expect the next part of the series? Another point: Maybe it's better to encapsulate the optics part away from the build chamber otherwise it's super common that all the optics and mirrors will contaminate with powder and the laser will fuse it to the mirrors. Only question is which glass can be used as a separator between the build and optics chamber.

[@marcelh2341]

Oh, and you don't need an extra motor for the roller. Just use the existing belt for driving the powder distributer.

[@MakingwithLuke]

@@marcelh2341 Not sure, but I plan to make a public release around the end of March. I have thought about separating the build chamber with glass, but the ZnSe window needed is very expensive. With a near IR or visible light diode laser, normal window glass transmits large amount of light, which is a pro for using that type of laser.

[@MakingwithLuke]

@@marcelh2341 Yep, I know, but I wanted the roller to be controllable, so I could move it clockwise and counterclockwise in order to compact the powder if necessary. I have since eliminated the roller assembly in favor of the simplicity of a wiper blade.

[@hfcandrew]

I make custom made foot orthotics. I was looking at purchasing a farm of sinterit and sintratec models, but the build volume was so small. Just didn't make sense. I need to nest about 18 pairs in at once, so I need about 30x30x30cm. So I looked at the ProdWays Promaker P1000X, but they quoted me $300K and a material powder cost of about $50 a pair, which was pushing my peak budget. Give all the advances occurring in SLS right now, including young scrappy kids like yourself, I'm considering just sitting back 2 years and see what happens next. Any reason why you are not testing prints in powdered plastic polymers?

[@MakingwithLuke]

That's very interesting. This printer will remain at 100x100x100(ish)mm for its next revision, but I intend to eventually design a larger one as I learn more about the process. I expect that in 2 years, SLS will be significantly more advanced for the budget user than it is now. I will be doing tests with polymers soon, but am busy building a new machine that is capable of polymers.

[@KiR_3d]

Hi, Luke! I like your project! Especially the approach (sugar!) and the attention to safety! Luke, what do you think about the conception of pre-heating a material? You know the benefits, I'm sure. Heating chambers aren't easy probably but as I've seen it in Sintertac (?) SLS printer, I must ask this. :) P.S. oh, yeah... I've listened to the "UV lights" part. But then what's about a full heated chamber? BTW, do you make thermal simulations for your project?

[@MakingwithLuke]

Hi! Thanks for the comment. I am currently working on the V1 version, which will be released to the public at the end of the month. It has a fully heated chamber using silicone heaters on the bottoms and sides of the chamber walls and IR heaters to heat the top layer of powder. The heated chamber is an absolute must for sintering anything besides sugar and maybe a few other materials, so I'm excited to see how it works.

Haha thanks! Glad to hear you liked it. I think I could get it to work with some types of wax, but have yet to test this. Its one of those materials I've been excited to try once I get V1 up and running.

Maybe you should show your brother next time!! I bet he is very decent!!

Why not try powder sugar?

[@will7671]

Amazing man, have you tried powered sugar?

[@MakingwithLuke]

Thanks! I have, and had issues with it, but am experimenting with making much smaller granules to print with.

[@tuskiomisham]

Have you tried powdered sugar?

[@jorge_mora_3625]

glass sugar? can this improove the resolution, because it is a most fine grain size ?

[@MakingwithLuke]

I can't say I'm familiar with glass sugar, but I have tried varying sizes of sugar, with varying results. Powdered sugar doesn't print properly yet, and large granules limit resolution. The powders in the middle of that work quite well, however.

[@MaxC_1]

I was wondering, did you abandon the 40$ 3D printer project that you talked about working and improving upon and posting the build videos? I personally wanted to make it and the lack of info about it is kinda annoying so any updates on it ever?

[@MakingwithLuke]

Yes, I have abandoned the project and moved on to a few other things since then, currently OpenFuse, as you can see. I will not be returning to that project. I would recommend checking out these two links for instructions on very similar builds. www.instructables.com/Curiosity-120-eWaste-Educational-3D-Printer/ www.instructables.com/eWaste-60-3DPrinter/ . If I may ask, what is your motivation for building the printer?

[@MaxC_1]

@@MakingwithLuke ah interesting. Yeah I figured that out going through your stuff. As of now I want to use the cheaper printer as a base model and sort of like prototyping to gain experience and build my final printer (prusa style) which is the reason I'm planning to build the smaller one. And also maybe print some parts for the full build. One question about your model, what was the final build volume? Also, I'm planning to use a SKR V1.4 instead of RAMPS because it will be a part for the full build eventually so are there any parts of the build which a board like SKR 1.4 makes easier/harder? Also did your design have any issues with moving the hotend? because with these weak motors it does concern me but looks like your design works great. Thanks in advance for any help!

[@MakingwithLuke]

@@MaxC_1 Sounds pretty neat. The build volume was a little under 40x40x40mm. I would go with the SKR board since it is simply better than the ramps board at nearly the same price. Really no reason to use a ramps board in 2021. This printer could move all axis without skipping steps, but the motors are inherently vey slow, and some kind of counterweight may help the z axis more more efficiently,

Have you tried sand as a material to make glass parts?

[@WeeIrishLaddie1]

[@litheodragon1827]

Recycling prints with this is probably gonna be very easy. Just powderize failed prints or simple pieces that already served their purpose and are no longer needed!

[@MakingwithLuke]

I think so! It's easier than making good filament out of recycled materials, at least. It would make sense for more expensive powders, too. Just mix the recycled powder in with virgin powder, and you should be golden

[@markilleen4027]

could it be upgraded to do metal

[@MakingwithLuke]

Even though polymer SLS and DMLS/SLM look very similar theoretically, they have some huge differences in practice. I don't see metal being usable in this machine, but I wouldn't say it's impossible.

[@markilleen4027]

@@MakingwithLuke yeah i don't think the laser would have the speed probably need a galvo head rather then the stepper motors and belts

[@jon9947]

Like all of your work I have seen this is amazing, a new level of amazing even! CNCKitchen done that salt video not too long ago, not sure if salt would work with this or if you have seen the video. He was looking for a cheaper finer salt, and someone in the comments mentioned a possible candidate, might be something to check out.

[@MakingwithLuke]

I appreciate that, Jon! I saw Stefan's video about using salt to anneal prints which is really cool. I don't know if salt is a viable powder either, but the great thing about this printer is that I can at least try!

[@jon9947]

@@MakingwithLuke This is the comment I was talking about: "The salt you want is called "pickling salt". It's much finer than table salt, has no anti-clumping agents, and is available in bulk at low prices."

[@rvisani]

@@MakingwithLuke No to salt! You will release chlorine gas when you heat it up with a laser. Very dangerous for you and your electronics.

[@MakingwithLuke]

@@rvisani Thanks for the insight! I'll definitely do more research into the necessary safety precautions before testing unknown materials like this.

[@MattKasdorf]

Amazing work! What of laser diodes? 🇨🇦

[@MakingwithLuke]

Thanks! I think diode lasers are interesting for this project, and may find a way to implement them into a future version, but for now this uses a 10600 nm co2 tube. A co2 laser is much more versatile with it's materials, since you can use any color material with it.

[@jorge_mora_3625]

can you print ABS powder ??

[@MakingwithLuke]

Its possible that I will be able to soon, but it is not on my priorities list, Nylon, PLA, PCL, sugar, and waxes will come first, then I will test other plastics. ABS is also concerning because of its fumes and high tendency to warp.

[@jorge_mora_3625]

Also an amazing idea Is to inyect acetone over ABS powder layer over layer.

[@th3engineer]

It would be awesome to see this machine working with grounded sugar.

[@MrRclemens]

Hi, first time I'm seeing this project. The website is down :( Is the project still going?

[@ChickenScratch]

But where is the project now?

[@oaiwjebdlla]

Is there a crowdfunding campaign for your project?

[@MakingwithLuke]

No, this will not be crowdfunded. I am strongly considering selling the machine as a kit or assembled machine, but only after I have finished the stable version. There is also a place to donate to the project for those interested in the description.

[@oaiwjebdlla]

@@MakingwithLuke okay, thank you!

[@souljiah2302]

Amazing man! Your the pioneer...

[@davidperry4013]

I like to see metal be used as a print material on this printer

[@marcelh2341]

The powder is really expensive. I don't think it's usefull for our purpose. Also, after the print you have to cook the print in an oven with really high temperatures. Secondly, you need a gas thight build chamber filled with inert gas otherwise the metal powder would just burn when the laser hits the powder. Lastly you need a high power laser, which isn't available to us and/or unaffordable.
