光敏树脂对快速原型件表面质量的影响

Effects of Photosensitive Resin on the Surface Quality of Prototype Object

为评价光敏树脂HSL 1的性能,比较了HSL 1和光敏树脂SL 7545的特性参数、力学性能和黏度,结果显示两种光敏树脂性能相近。研究了两种光敏树脂对快速原型件表面质量的影响,对快速原型件表面粗糙度值的研究表明:快速原型件的上水平表面质量最好,下水平表面质量最差,侧表面质量受倾斜角度影响;且快速原型件表面质量受到光敏树脂组分、透射深度、单层固化强度和黏度的影响。

To evaluate the property of photosensitive resin HSL1, we compared the characteristic parameters, mechanical properties and viscosities of HSL1 and SL7545, and found that the property of HSL1 is close to that of SL7545. Through studying the roughness of prototype Burface, we analyzed the influence of above two photosensitive resins to the surface quality of the prototypes. We found that top surface is of the best quality, while that of the under surface the worst, and the surface quality of side surfaces are influenced by the tilt angles, what＇s more, we founded that the surface quality of prototypes are also influenced by ingredients, penetration depth.cure strength of single layer and viscosity of photosensitive resins.
