@wjsteele @THEJATMN @johnoly99 @3DChameleon @benheck Also, couldn't quite get the fridge up on your car so I just left it there. You can Venmo me the money later!

[Luke Cunningham @MakingwithLuke]

@wjsteele @THEJATMN @johnoly99 @3DChameleon @benheck 🤣🤣 I have to admit I just brought a fridge to MRRF and hosed down the floor to say I couldn't print because of humidity. No SLS to see here

[Luke Cunningham @MakingwithLuke]

@MCHRISP1 I'll be there in person if it's open!

[Luke Cunningham @MakingwithLuke]

@wjsteele @3DChameleon I reeally like this, definitely reminds me of the first 3d chameleons you showcased. Also reminds me of Joshua Vasquez's hackaday article: https://t.co/uKF23owiQX

[Luke Cunningham @MakingwithLuke]

@3dmakerkid OpenFuse could definitely print this, though I'm not sure how well it would capture details right now. Once I get some new sieves in to make smaller powder and reassemble V0 (or V1 :D) I may just have to print this out!

When it comes to testing a new #3dprinter - a @Dizingof design is always a good challenge!

@MetSysAdv @E3DOnline @CNC_Kitchen @makersmuse @BillieRubenMake @toms3dp @joeltelling @RealSexyCyborg @EmporiumThought @josefprusa @mattyxb @foosel I appreciate that!!

[Luke Cunningham @MakingwithLuke]

@fbujold With cryogenically cooled plastics as well, but may need to build a ball mill to powderize the material instead of a blender

[Luke Cunningham @MakingwithLuke]

SLS progress! I've put in a new, more controllable laser tube, doing some ceramic heater testing, and sintering finer powder grains. It's coming along, and I'm excited to be moving closer to a public release! https://t.co/JiWQvWHijc #SLS #3dprinting #additive #projectopenfuse

[Luke Cunningham @MakingwithLuke]

@fbujold Since I'm just using standard sucrose sugar right now, I'm actually just putting fine granulated sugar through a <250 micron sieve to filter larger sizes out. I can then blend the larger particles in a food processor and refilter. I want to try a similar technique

[Luke Cunningham @MakingwithLuke]

https://t.co/hXywjo3Xi3 Video on the SLS printer is out! Go check it out to see the new info on it

[Luke Cunningham @MakingwithLuke]

@MetSysAdv That's a good idea, but you may consider using the standard E3D/ Jubilee tool plate design. It is proven to be the best design so far. Electromagnets are heavy and less consistent than the mechanism used in those printers.

[Luke Cunningham @MakingwithLuke]

@MetSysAdv What board do you plan on using? I'd recommend Duet most of the time, but if cost is the ultimate goal, I'd go with klipper.

[Luke Cunningham @MakingwithLuke]

@MetSysAdv Cool stuff! Send me some pictures/CAD models of the machine. I'd like to see where you're going with it. Toolchangers are pretty expensive right now, categorically, but there have been some really great strides to bring the price down. It would be great to have some more options!

[Luke Cunningham @MakingwithLuke]

@AutoArtMachine That could be an interesting approach for higher cost materials, though. Degradation would have to be accounted for somehow, but its doable.

[Luke Cunningham @MakingwithLuke]

Just finished the #VERRF stream! I'm here to announce OpenFuse SLS, a fully open source SLS 3d printer. I've been working on it for almost a year now and am happy to get it out there. Go to https://t.co/CmDH36Zuw0 to see updates and join the bidding community.

[Luke Cunningham @MakingwithLuke]

@AutoArtMachine The great thing is that sugar is so cheap that I can just buy more and grind it to the size I need for printing! I could make a system for dissolving and evaporating the solvent (water) to leave sugar, but it would likely be more trouble than its worth.

[Luke Cunningham @MakingwithLuke]

@AutoArtMachine The sugar models are surprisingly strong, actually. They obviously won't bear much weight, but they also don't crumble in your hands. I print them with 100% infill, so they are also quite dense.

[Luke Cunningham @MakingwithLuke]

@TheLightSpeedz There's a lot that could go wrong, though, so making sure every precaution is taken is a necessity for me. Fumes, fire, breathing powders, high power co2 laser, and high voltage aren't too good for you if not properly controlled!

[Luke Cunningham @MakingwithLuke]

@TheLightSpeedz It's actually very possible! As long as the correct settings are used, and the material isn't small enough to become airborne, it will be a very safe printer to use. Sugar is a great material for testing and staying safe

[Luke Cunningham @MakingwithLuke]

@3dmakerkid Sure is! Actually the first one I've ever had the patience to finish the print 🤣

[Luke Cunningham @MakingwithLuke]

@MetSysAdv I thought about making a drop in powder handling system for an existing machine, but I think it is better to just build it from scratch actually. Cost and complexity goes down, machine quality goes up
