Abstract

The PerFactory® technique from Envisiontec is unique in its method of manufacturing parts in discrete voxels, compared to the technique of smooth laser contouring implemented in the traditional SLA process. This method of approximating the contours with “Voxels” (3 dimensional pixels) has a pronounced effect on surface finish of the finished part. This work investigates the effect of pixel size, and also build angle and build direction on surface finish of parts built on the Envisiontec RP machine. A high surface finish is important because, apart from offering surfaces of high quality, it also helps to reduce post-processing time and to increase accuracy.
