About
​
Photopolymer resins are baked in UV or LCD light of a particular wavelength and the light inhibits the curing process.
For best ready-to-use prints with high tolerance parts, it is the first process to be preferred, but unlike FDM the physical properties are not pin-pointed instead they are termed as ABS-like and more of plastic-like resins.
The most common resins are
​
-
Tough resin
