(a) Schematic diagram of DLP system. (b) Layer slip error due to poor build plate adhesion of the first layer. (c) Incomplete fabrication due to recoating error. (d) Shape distortion of the structure due to insufficient polymerization. (e) Over-curing due to excessive polymerization. (f) Chemical structure of isosorbide dimethacrylate (ISDM), the primary material of photocurable resin. (g) Chemical structure of poly(tetrameghylene ether) glycol-polyurethane acrylate (PTMG-PUA) as an additive material to improve the properties of phtocurable resins.
