SLA 3D printers use light-reactive thermoset materials called “resin.” When SLA resins are exposed to certain wavelengths of light, short molecular chains join together, polymerizing monomers and oligomers into solidified rigid or flexible geometries.
What material is resin printing?
Plastic 3D Printing Processes – Stereolithography (SLA) 3D printers use a laser to cure thermosetting liquid resins into hardened plastic in a process called photopolymerization. Selective laser sintering (SLS) 3D printers use a high-powered laser to fuse small particles of thermoplastic powder.
What type of plastic is 3D printing resin?
ABS. ABS filament is the most commonly used 3D printing plastics. It is used in the bodywork of cars, appliances, and mobile phone cases. It is a thermoplastic which contains a base of elastomers based on polybutadiene, making it more flexible, and resistant to shocks.
Is 3D printed resin plastic?
Like SLA, DLP 3D printers use liquid plastic resin, but instead of a UV-laser beam, the resin is melted with arc lamps. This light source causes the impressive printing speeds because the amount of light allows the resin to quickly harden.
What is resin filament?
Filament printers are also referred to as FDM (Fused Deposition Modeling) or less commonly FFF (Fused Filament Fabrication) machines. These terms are interchangeable. Resin printers form parts from liquid resin which cures, or solidifies, when it is exposed to UV light.
What polymer is SLA resin?
The liquid materials used for SLA printing are commonly referred to as “resins” and are thermoset polymers.
