A Study on 3D Printing process for improving surface roughness based on Photo-curable polymer material
Abstract
Recently, 3D printing technology has been applied to various fields. In the manufacturing market of automobile and electronic products is in order to rapidly develop and launch new products. MID, embedded, etc., such conductive circuits pattern research on 3D printing sculpture surface making is actively under way. But, there is a problem that the surface of the sculpture made by 3D printing has a stepped shape and an area error due to a step formed between each layer and the layer, resulting in a rough surface of the sculpture. Therefore, it is necessary to study the surface roughness of the sculpture because the conductive circuit patterns on the surface of the sculptured material permeate between the layers and the layer can not be formed uniformly. In this paper, a 3D printing system based on photo-curable polymer material was developed and process studies were carried out to improve the surface roughness of photo-curable sculpture. The surface roughness of the photo-curable sculpture is determined by the area error, and the area error can be controlled by the pattern thickness. Experiments were conducted on the pattern thickness using the output pneumatic pressure and the printing speed as process variables controlling the pattern thickness. Photo-curable sculpture was made by selecting the process conditions according to the pattern thickness. The surface roughness of the photo-curable sculpture fabricated by the pattern thickness was measured using a 3D nano profiling system, and the change of the surface roughness of the photo-curable sculpture was confirmed according to the pattern thickness. In order to confirm the surface accuracy of the photo-curable sculpture, the sculpture was fabricated under the same process conditions by using FDM 3D printer which is widely known and compared with the surface roughness of the photo-curable sculpture. In addition, the surface precision photo-curable sculpture was confirmed by conducting conductive circuit pattern fabrication experiments on the surface of the photo-curable sculpture.
