Study on shrinkage properties of photopolymer resin for laser rapid-prototyping;

In the process of repaid prototyping,control of solidified depth of photopolymer resin is a vital factor for affecting the accuracy of the shape and dimension of parts.

A novel type of photocurable resin was sythesis through Michael addition of acrylate containing polybasic double bond such as TMPTA with polybasic aliphatic amine such as ethylenediamine and triethylenetetraamine,which was characterizaled by 1HNMR,FT-IR,GPC and UV-curable experment.

The influence of polymer filler on the shrinkage of photocurable resin used for stereolithography is studied by measuring the viscosity、the specific gravity、the photocuring speed、the linear shrinkage,and the volume shrinkage of the resin containing polymer filler.

Telled about the technological process of the Stereo Lithography Apparatus,and introduced the photocurable resin that is the materials specialloy use in the SLA.

This paper introduces a method for real time measurements of the shrinkage of the photopolymer.
