Ballistic Particle Manufacturing: Basics and Applications

This lecture covers the Ballistic Particle Manufacturing (BPM) process, where 3D parts are built using droplets of molten wax delivered by nozzles. The consolidation principle is liquid phase bonding, with details managed through nozzle control. BPM is also known as Multijet Manufacturing (MJM) and involves the use of different materials for construction and support. The lecture discusses the mechanical properties of parts produced, equipment specifications, and companies involved in BPM. Additionally, it explores the advantages and disadvantages of BPM compared to Fused Deposition Modeling (FDM). The lecture also introduces Laser Metal Wire Deposition (LMWD) as a metal version of FDM, where metallic wire is melted by a laser to build parts.
