@msjboy The point is I want to see an FDM printer using thermal plastic print at 20 microns, not a resin based printer. I print at 100microns because its easily achievable with FDM, even 50 micron is doable. The problem is the nozzle of and the feedrate control that is associated with 10-20 microns are so fine that some printers have a hard time. The time associated as well is the reason why industry companies dont bother touching that resolution with FDM.
Doing home 3D printers is not just about our sw hobby, its much much more. But for our hobby even the plastics are 100% reef safe. PLA is bio pellets, so it will degrade in our systems so thats a no go. ABS on the other hand is lego, it is also fully safe. and I use it in my system and have printed things for friends as well. That includes the ability to print grid wheels that ATB came out with not long ago.
