Abstract
Polymer powder bed additive manufacturing is the most prolific industrial additive manufacturing technology, thanks to Laser Sintering and High Speed Sintering (HSS) technologies. Recent advancements have included adding additional laser systems (with significant costs) and the use of HSS technologies to increase machine throughput. However, polymer powder bed AM technologies are still very limited on processable materials and quality control. Ascend Manufacturing is leveraging high power digital micromirror devices (DMD) to overcome these obstacles and provide a commercial next-generation additive manufacturing solution. This presentation will introduce Ascend Manufacturing's novel Large Area Projection Sintering technology and discuss the additional advantages of area-based processing.
