Abstract Scope |
Laser Foil Printing (LFP) is a laser-based metal Additive Manufacturing (AM) method recently developed at Missouri University of Science and Technology. This study investigates and compares two different methods of automating fabrication of parts for the LFP process. Specifically, the edge elevation issue due to laser cutting is investigated. Edge elevation occurs after the foil cutting operation, which is an essential step of the LFP process. Previously, mechanical polishing was done onto the fabricated layer to remove the elevated edges. However, as mechanical polishing is very time-consuming, the current study focuses on two other methods to get rid of the elevated edges. One of them uses laser polishing to remove the elevated edges. Another method is changing the order of the fabrication steps between pattern welding and cutting in the LFP process. Comparisons are made to observe the differences in part quality, properties, and building time between these two methods. |
