Table 1 Generalized standard terms for 3D printing technologies. For each standard term, one or more commercial and other terms are listed, along with a description of the technology type, and the associated identifier in the RadLex terminology. Please refer to the ISO/ASTM standard for a complete description of each generalized term [15]

Binder Jetting

• ProJet Color Jet Printing (CJP)

Liquid agents are selectively dropped onto powder media. Subsequent infiltration or heating may be required.

RID50562

Directed Energy Deposition

• Laser Engineered Net Shape (LENS)

• Electron Beam Additive Manufacture (EBAM)

Focused application of energy and material selectively melted and fused on a build platform or part.

RID50563

Material Extrusion

• Fused Deposition Modeling (FDM)

• Fused Filament Fabrication (FFF)

Material is dispensed, often through a heated nozzle, onto a build platform.

RID50564

Material Jetting

• Nano particle Jetting (NPJ)

• Drop-On-Demand (DOD)

• PolyJet

• ProJet Multijet Printing (MJP)

A print head dispenses droplets of media, usually a photopolymer, onto a build platform where each layer is solidified or cured.

RID50565

Powder Bed Fusion

• Selective Laser Sintering (SLS)

• Selective Laser Melting (SLM)

• Direct Metal Printing (DMP)

• Direct Metal Laser Sintering (DMLS)

• Electron Beam Melting (EBM)

• Multi Jet Fusion (MJF)

Powder media is deposited on a build platform and subsequently bonded together through a heating process.

RID50566

Sheet Lamination

• Laminated Object Manufacturing (LOM)

Discrete layers of material are fused or glued together to form an object.

RID50567

Vat Photopolymerization

• Stereolithography apparatus (SLA)

• Direct Light Processing (DLP)

• Continuous liquid interface production (CLIP)

Liquid photopolymer is selectively exposed to a light source facilitating layer-by-layer curing.

RID50568
