Ahhh, cool, thanks. The 2nd one is more interesting.

Asking because someone mentioned in a video on lost PLA casting, than sugar burns out cleanly at high temperatures.

So, the idea of mixing extremely fine sugar with (say) aluminium or titanium powder, then seeing how well they bind together when lasered (sintering like).
The caramelization process seems like it would keep things bound together pretty well initially.

Then from there, putting the resulting object into a furnace for burning out the sugar, to complete the sintering process.

Might be time for to invest in a cheapo laser diode after all, and do some experimentation. :D

This was done with Mach3 & J-Tech's PicConvert DAC for modulating a M140 2W 445nm laser diode on Poplar. The PicEngrave Pro 5 settings were A.000 Min & A-.0255 Max, 70IPM, 25% Feed Rate Change and .006 Pixel Resolution at a 45D angle using the Ellipse feature.

The size is 4.75" X 5.75" with 600,229 lines of gcode and it took 1:36:46 in time to engrave.

Laser engraved on 12"X12"X.125" piece of Birch Ply with our 6W Shapeoko 2 using Larry's MultiMode grbl 1.0c that can be downloaded from here..

https://discuss.inventables.com/t/xcarv ... -fix/28943

The 1,237,164 lines of gcode was generated with PicEngrave Pro 5 and streamed with PicSender. After the engraving was finished, I used the Manual Move menu in PicSender to cut it out with the laser.
