I want to make one of them SLA 3d printer kind of stuff but i dont know anything that solidifies after getting hit by some sort of beam or particle, also i know exotic matter and neutron might work but i think the neutron would wiggle around too much. does anyone know any materials for that?
Pste can be hardened under pressure,bizr can he heated to make it solid,Mwax can be cooled there are various ways u just need to find the right one.
