Expendable Shape Tools: Galvanic Molding and Vacuum Casting

This lecture covers the concept of expendable shape tools in replicative processes, focusing on galvanic molding and vacuum casting. Galvanic molding involves manufacturing metallic parts through electroplating of counter-parts, while vacuum casting produces plastic parts by casting resin in a silicone mold. The lecture explains the principles, processes, and examples of these techniques, highlighting the use of master models and lost patterns. It also discusses the combination of vacuum casting and investment casting, showcasing the economic and technological benefits of these additive manufacturing methods.
