Curing Characteristics of the Photopolymer Used in the Solid Laser-Diode Plotter RP System

摘要: Most stereolithography (SL) processes employ ultraviolet (UV) or diode pumped solid state lasers to cure the associated photopolymer build a 3D part. A UV laser is more expensive in initial cost and maintenance than semiconductor laser. used laser-diode plotter (SLP) rapid prototyping system specific (DF2000). The DF2000 formulated from based resin, hardening agent, powder. wavelength of SLP 680 nm range red colour light. In this work, curing effect visible spectrums generated by lamp on was investigated, using differential scanning photo calorimetry (DSPC). DSPC result indicates that degree blue light better when also seems showing shorter wavelength, photopolymer. Hence, (405 nm) even higher-power lamp, instead laser, can be employed increase system, quantitative processing parameters mechanical property test specimen studied Taguchi method. results show fabricated part proportional indicate pitch most sensitive parameter affecting and, hence, property. Therefore, characteristics could as an index Also, employment rather further improve fabrication speed
