Excited about building DIY SLS printer? See how it prints!

[@fluxcapacitor]

With today's surprise acquisition of Micronics by Formlabs and the cancellation of their cheap "Micron" SLS 3D printer, you're now the only one left in town. Congratulations, SLS4all.

[@SLS4All]

I was working on this video last few days, published it and after receiving your comment, which was the first one, I was really surprised what happened meanwhile...

[@fluxcapacitor]

What a synchronicity

[@Suprm_Lord_E]

Seriously? That's the worst tech news i had today. Let's hope this guy don't sells out too, we need affordable open source SLS to be a thing

[@fluxcapacitor]

@@Suprm_Lord_E I was just congratulating Tomas and pointing out that simple factual situation. I never said the Micronics acquisition was a good thing for customers and the industry.

[@igorchak48]

I feel like SLS will be getting more popular once it becomes more user friendly. We need a like a Bambu Lab type of an SLS printer!

[@LOBrien_]

Talk about perfect timing to release this video. Glad to see SLS printing for consumers is not entirely dead! Best of luck!

[@juliusklaas]

I am so glad someone as capable as you is pushing open source SLS instead of selling out.

[@jp.girardi]

I get the feeling you weren't upset about the existence of Micronics since the goal was to make SLS accessible to everyone. I even hoped you could collaborate because you and those guys had great ideas to lower the cost of an SLS. It's sad to see they're no longer in the game. Although I really love this project, I hope some of their ideas can inspire us to further reduce the price of SLS printers to below $3k in the future. Way to go, my guy!

I encourage everyone to support this project to counter the greedy policy of well established companies that kill each one budget SLS competition (first WeMatter, followed by Sintratec and now Micronics)

[@TheElectronicDilettante]

I thought I heard in a video that this may be the release candidate that you share with the world. First off, if you open source the HW and SW for all of us DIYers, I just want to say ,Thank you! That’s an amazing gift to the planet. I’ve just recently gotten into 3d printing to help fill the days as I quickly approach my 50th birthday. From the moment I removed my first printed part, I was absolutely hooked. I looked into resin printing but it’s not for me. Then I came across SLS Printing… hooked again. I’ve vowed to be printing with some form of SLS printer as I count down the 23 months til my half century mark. I look forward to seeing how your project progresses. If and when you release it to the masses, I’ll be one of the first to start building one. If you decide to sell it, I’ll be one of the first to buy it. You came up with an elegant, functional design. It looks good, the prints I’ve seen you produce are jaw dropping. All around, it’s truly quality work. Thanks for the videos. I just caught the fact that you’ve released it already. Thank you!!!

[@SLS4All]

What to say than just THANK YOU for your kind message. Since my half century mark is also approaching quicker than I would like to I fully understand your feelings.

[@MrOgMonster]

Amazing! $7000 is an amazing price point for the technology - unfortunately still too high for me though, hopefully this continues to develop and reduce in costs over time, I would love one of these!

[@GlennDeBacker]

I remember my first (open source) FDM printer that was 2000 euros with a build plate of 12x15x15cm. If i see how it evolved and what is available for a fraction of that price or even in the same ballpark like Vorons... I'm sure projects like these will reduce the price and make it more accessible. I've seen it numerous times with CO2 lasers, FDM printers, resin printers, 3D scanners,...

[@martinfinne7259]

At least for hobby use the prize for print media also needs to come down quite a bit

It's not something that I can afford and to be honest I'm to busy with 3D ceramic printing anyways, but this is certainly something that we need to hopefully kickstart another 3D printing path like we have seen with FDM and Resin printing!

Really nice UI. With the demise of micronics, this becomes more interesting. I could see that using a RPI 5 in place of the 4 could be advantageous in arranging parts quicker.

[@SLS4All]

Thanks! We started with the RPI 4 in our first prototype years ago. Then we moved to the RockPi 4B because during corona RPI was impossible to buy. But we faced significant problems with the long term stability. Therefore we moved to RPI 5 as soon as at was possible to source it easily. So, it is in there already.

Micronics just became a sellout, and this video pop out on my recommendation list. What a day, my question is that, is it possible to have it made with a large build volume? if so which parts that needs to be modified to accommodate the large build volume?

[@SLS4All]

Yes, it is possible. In the Z-axis it would be relatively easy to redesign it to have printer with a deeper chamber at the end. XY axes which means galvo controlled axes will be a bit tricky if you think about more than say 15-20mm in each axes direction. It will mostly be about the mechanical parts and maybe about some of the heating elements.

[@brianhutchinson7863]

No discouraging from me and it already looks great. Been aware of you're work for a little while. I know it could be a ways off but what is involved in being capable of metal? Im not talking about sintering the metal directly with the laser but using a metal powder with binder. The binder is sintered with the low power laser then parts removed from cake and finished in a sintering furnace. I think you should look into finding suppliers of such metal/binder combo powders and start experimenting with those. A sintering furnace should be easy to engineer in comparison to the Inova.

[@SLS4All]

Thanks for yor support. You are right. Cold metal fusion, how this is called, should be possbile with the Inova. I know the company making materials so I plan to contact them once I have some spare time.

[@brianhutchinson7863]

@@SLS4All That's great. Calculating shrinkage percentage of caused by the sintering furnace on the parts for various metals should be easy. There would definitely be challenges. I see lots of value in you're equipment with polymers especially for composite materials as it is. Metal is really kinda the "holy grail" though you know. It's really what most people want I think. Anyway was happy to have sparked the conversation and while I don't think I can afford the SLS at least for a while I wish you continued success and good luck.

[@QuebecoisSti]

It looks pretty promising ! Thanks for having it Open Source/DIY, we don't see that everywhere. In hurry to see more complex prints (eg. High details figurines), those were quite easy one... Furthermore, comparison of parts strength vs FDM prints could be nice to see if SLS is worth it. Total printing cost per gram or volume can be calculated I assumed ?

[@SLS4All]

Thanks! If you are interested in prints with more details check this gallery: sls4all.com/test-prints-gallery/#bwg20/590 Mechanical tests are planned, I will post the results. As for the costs - yes it can be calculated. Powder which I use is about 100USD/Kg.

[@Orlaz92]

Wow the software seems very good

[@TimoBirnschein]

This thing is amazing! I hope what's published remains published regardless of what the future holds for this wonderful project! What's killing me is the post processing of these parts. PA12 is a crazy strong material that speaks for itself once you have in in your hands but the process is even more involved and much more messy than even SLA which most people already don't want to do. Seems like the next step is to develop and auto-cleaner as well as a proper powder recycler. Then, while we're at it, we need to develop a part recycler. I don't see why that wouldn't be possible. Just grind down the parts back to powder of the same grain size. I'm sure there is a way to so that reliably similar to the original industrial process as well. Keep up the amazing work!

[@SLS4All]

Thanks! Post processing can be annoying but not if you have the right tools and accessories. I don't think it will be easily possible to have fully automated post processing on the small SLS machines, but maybe I am wrong.
