Extrusion Process in Additive Manufacturing

This lecture covers the extrusion process in additive manufacturing, focusing on Fused Deposition Modelling (FDM). The process involves building 3D parts from a molten thermoplastic wire extruded from a heated nozzle, with ABS being the most suitable material. The lecture explains the principles of consolidation, the equipment involved, mechanical properties of parts, companies specializing in FDM, and comparisons with similar processes like BPM™. Advantages of FDM include simple operation, gradient properties, and custom item fabrication, while limitations include material restrictions and anisotropy in part properties. The lecture also discusses the BPMTM process, companies like SOLIDSCAPE™M and 3DSYSTEMS™, and their applications in jewelry manufacturing.
