The Study of improvement for Shape Accuracy in Stereolithography

광조형법에 있어서 조형정도향상을 위한 연구

In the stereolithography process, the accuracy of cured shape depends on laser power, scanning speed, scanning pattern, resin characteristics etc. When three-dimensional objects are built, higher laser power gives higher building efficiency. Normally we could control scanning speed and scanning pattern, which affect curing thickness and generate volume of curl in & after building. Oligomer, Monomer and Initiator are major components. Kinds and of them decide characteristic of resin. In this paper, we deak with major facts and their characteristics for precision shape building.
