Curtain measurement in Rapid Prototyping

Abstract [en]

This report is a study of different measurement techniques for measuring thickness and uniformity of a thin film produced by Rapid Prototyping machines (Next Day) in the company Materialise. Knowing the uniformity and thickness of the curtains used in Next Day machines in Materialise is important, due to the direct relation between curtain uniformity and accuracy of the produced parts. Non-uniform curtains results in non uniform parts. The goal of this thesis was to find a method to measure the uniformity of the curtain produced by Next Day machines and if possible measure the thickness of the curtain. In this report it was found that the confocal measuring method is the best method to measure both curtain uniformity and curtain thickness compared to other tested methods. Another important result found, was that it is possible to change the uniformity and thickness of the curtains by adjusting the dies which produces the curtains. Making a mechanical setup was also a part of the goal of this thesis. A setup was constructed for confocal measuring method.
