Basics
This page covers the various methods of 3d printing
FDM
- Fused Deposition Molding or FDM
- AKA Fused Filament Fabrication or FFF
- Essentially a hot glue gun on a 3 axis cnc gantry
Lamination
- Automated Cutting and laminating of sheets
- Most common one uses printer paper, and can make full color models (More so artistic uses, or for education/concept demonstration
- Plywood version combining this and a CNC Router would be an intresting system
Vat Polymersation
- SLA Stereolithography, uses a laser in a similar manner to a CRT's electrom beam to scan polymerise the layers, relitively obsolite with the next tech
- CLIP (3D Printing Technology) / Screen Based Polymerisation same process as SLA but with a screen or projector, each frame is a layer, thus near invisible layerlines, great structural properties and precision
High Energy Deposition
Sintering/Melting Based
- SLS selective laser sintering, uses a laser to sinter powder together
- SLM selective laser melting Better structual qualities than SLS, and may require less post processing
- EBM electron beam melting Can use HIGH MELTING POINT METALS such as TITANIUM, main use cases are turbines, and medical devices
