Study Notes
Additive Manufacturing Technologies
- Additive manufacturing (AM) processes create objects layer by layer, unlike traditional subtractive manufacturing methods that remove material
- AM technologies are diverse, using various materials, energy sources and processes
- Different classifications exist based on raw material type, process type or basic technology
- Key aspects include materials used in the process, whether liquid, powder or solid sheet, and the process itself
Classes of AM Technologies
- Vat photopolymerization (SLA, DLP, CLIP) uses a liquid photocurable resin, cured by UV light.
- Sheet lamination uses sheets of material, cut and bonded to create the object.
- Powder bed fusion (SLS, SLM, DMLS, EBM) uses a powder bed fused together by laser or electron beam.
- Material extrusion (FDM, FFF, Robocasting, Bioprinting, Contour crafting) extrudes a molten or semi-molten material into layers.
- Binder jetting (3DP, MJP) selectively deposits a liquid binder to bond powder materials.
- Direct energy deposition (LENS, EBAM, LMD) uses a focused thermal energy source to melt and deposit material.
- Material jetting (PolyJet) uses droplets of material selectively deposited.
Key Considerations
- Material properties and characteristics are crucial for AM
- AM is becoming more common and is a rapidly evolving technology
- Speed, cost, and scalability vary between AM processes.
- AM design often emphasizes functional and geometric complexity
- Waste reduction is commonly considered in AM design
- Post-processing steps are often necessary for enhanced part quality, properties, and aesthetics.
