Curious if anyone can shed light on this for me. I was looking at a couple of nice 3d printed models. I keep seeing this white powder type substance on the base of the prints. It is obvious they printed in a color and painted, but not sure if this for the paint to stick, add texture, etc… What is this substance?
I’d guess that these are made on Zcorp-style powder printers, so the visible powder would be gypsum residue from the manufacturing process or wear from people touching it.
Or it was printed with a whitish filament and the extruder is having issue where it slips some and then grinds some filament when it should be extruding it?
Prints that look that nice, I don’t think they are having any extruder issues lol. Looks like SLS power to me.
Thomas seems right. This was a binder jetted print and there was a pocket of powder that wasn’t cleaned up. It may have broke loose during handling it shipping.
Ahh. That makes sense guys. I was looking at the layers and assumed this was a filament extruded part.
Good call! Thanks!
@St_John I looked at that video. I have seen some stuff about the Model T 3D printer before. It seems to me that the biggest feature of that printer is the enclosure. It prints PLA only, but at 80mm/s, so that is a decent speed in my opinion.
The smallest layer height on it is my default layer height. Theiy can go from 0.2 to 0.4mm layer height but the nozzle is 0.4mm, so that will not provide much squish using some of the slicers out there. It has wifi and only some supported systems, so it may be that it has its own custom slicer to get it the amount of squish that it needs it. It is hard to tell without getting more information on it.
Something seems curious about this. It seems to have spots in the video where they are selecting a color. It makes me wonder if it has ink cartridges for inking up white/natural PLA. If anyone can find details on that, please let me know. That would be another great feature that it has, if it has it.
