Glossary of acronyms
- FFF
- Fused filament fabrication, a process that squeezes a molten filament.
- FDM
- Fused deposition modeling, a trademarked term for FFF.
- DMLS / SLM
- Direct metal laser sintering, a process that fuses metal powder by sintering.
- SLM
- Selective laser melting, a process that fuses metal powder by melting.
- ABS
- Acrylonitrile butadiene styrene, a common thermoplastic with relatively high heat resistance.
- ABSplus is a stronger, proprietary blend of ABS by Stratasys.
- PLA
- Polylactic acid, a bio-plastic. Easier to print, stiffer, and more brittle than other plastics.
- PLA is a term for any blend that enhances some characteristic.
- PETG
- Polyethylene terephthalate (glycol-modified), a plastic made by changing the chemicals used to synthesize the more common PET. Easier to print than ABS, and moderately better heat resistance than PLA.
- Often used in consumer-level printers when creators desire better heat resistance than PLA or need more flexibility.
- ECM
- Electrochemical machining, a process that uses electricity to chemically machine metal. Commonly used in 3D printed firearms to create DIY barrels with rifling, greatly increasing accuracy.
FCG
- Fire control group, the trigger mechanism of a firearm. Commonly used to refer to the AR-15 fire control group.
