Abstract:
Solidification process and phenomenon of solidification shrinkage
lagging polymerization are studied in SL, time-effect conception is put
forward and the effect of shrinkage time-effect on parts’ curl
distortion and several embodiment are studied. By manufacturing parts,
the theory put forward is validated. Improving manufacture process based
on time-effect is used to minish the curl distortion of parts, the
result shows the curl distortion is improves greatly.
Key words:
Rapid
prototyping Photocurable resin Time-effect Curl
distortion
