5 Questions
Explain the process of Vat photopolymerization in additive manufacturing.
Liquid photopolymer in a vat is selectively cured by light-activated polymerization.
What are the 7 categories defined by the ASTM standard for additive manufacturing processes?
- Material extrusion, 2. Vat photopolymerization, 3. Powder bed fusion, 4. Material jetting, 5. Binder jetting, 6. Directed energy deposition, 7. Sheet lamination.
How does material extrusion work in additive manufacturing?
A material is selectively dispensed through a nozzle or orifice.
Define powder bed fusion in the context of additive manufacturing.
Thermal energy selectively fuses regions of a powder bed.
What is the process of directed energy deposition in additive manufacturing?
Focused thermal energy is used to fuse materials by melting as the material is being deposited.
