| Abstract Scope |
Large area projection sintering (LAPS) is a powder bed fusion (PBF) process that is currently being developed. LAPS fuses layers of polymer similar to laser sintering (LS), but utilizes a projected grayscale image from a modified projector to fuse the layers. Initial research has shown that mechanical properties from samples oriented in the build plane are superior to LS samples produced from the same material. However, it is necessary to examine the properties produced orthogonal to the build plane as well. This study compares the properties (strength, elongation at break, and density) of samples oriented in the build plane and orthogonal to the build plane. Printing orthogonal tensile bars requires a smaller sintering area and more layers—increasing sensitivity to edge effects. The potential effects of these requirements are discussed. To better understand the sources of disparity between samples, the temperature history was recorded and analyzed as well. |
