Hi to the group. I posted a 3D printing question on the Home Model Engine Machinists forum and the suggestion was made that I try it here. I want to start experimenting with lost PLA casting and have spent some time learning to use my new 3D printer. The general consensus on other forums is that PLA needs about 730C in a kiln to burn out completely ( as opposed to melting out ). Lately a new generation of 3D resin printers has arisen at a much lower price than their predecessors. Resin printers were formerly very expensive. They do a nicer print than PLA printers. I am curious what the burnout temperature would be for resin. Higher or lower than PLA? For the small engine parts I want to cast resin printing would make better models than PLA.
