The 11 Types Fit Into Larger Families
The main 3D printing technologies are best understood as families rather than isolated machines. Industry references commonly group additive manufacturing into categories such as material extrusion, vat photopolymerization, powder bed fusion, material jetting, binder jetting, directed energy deposition, and sheet lamination.
The 11 Types Fit Into Larger Families
The main 3D printing technologies are best understood as families rather than isolated machines. Industry references commonly group additive manufacturing into categories such as material extrusion, vat photopolymerization, powder bed fusion, material jetting, binder jetting, directed energy deposition, and sheet lamination.
A beginner does not need to master every process at once. Start with what each process uses as material, how it forms a layer, what it is good at, and what limits it has.
1. FDM or FFF
FDM, also called FFF in open terminology, extrudes melted thermoplastic filament through a nozzle. It is the most common desktop process and works well for hobby prints, fixtures, prototypes, organizers, brackets, and larger objects.
Its main limits are visible layer lines, bed adhesion, support marks, and strength differences by orientation.
2. SLA and 3. MSLA/DLP Resin Printing
SLA and related resin processes cure liquid photopolymer with light. Modern desktop resin printers often use masked LCD exposure or DLP projection rather than a laser, but the core idea is still curing resin layer by layer.
Resin printing is excellent for miniatures, dental models, jewelry masters, and fine detail. It also requires gloves, ventilation, washing, curing, and careful resin waste handling.
4. SLS and 5. MJF
SLS uses a laser to fuse polymer powder, while MJF uses agents and heat to fuse selected powder areas. Both can make functional nylon parts without conventional supports, making them strong choices for batches, complex shapes, and durable prototypes.
The tradeoffs include powder handling, cooldown, surface texture, and post-processing.
6. Metal Powder Bed Fusion and 7. Directed Energy Deposition
Metal laser powder bed fusion builds dense metal parts from powder using a laser or electron beam. Directed energy deposition feeds powder or wire into an energy source, often for repair, large features, or near-net metal builds.
These are industrial processes requiring serious safety, materials, and quality control. They are not casual desktop workflows.
8. Binder Jetting, 9. Material Jetting, 10. Sheet Lamination, 11. Bioprinting
Binder jetting deposits a binding agent into powder and may require post-processing. Material jetting deposits droplets of build material. Sheet lamination bonds sheets together. Bioprinting adapts additive principles to biological research and medical development contexts.
These technologies serve different applications, from sand molds and full-color models to research materials and specialized manufacturing.
