SLA – stereolithography

Procedure description

Hardening of a liquid photopolymer using a UV laser
Synthesis reaction transforms monomers into polymers
Layer-by-layer structure with support structure
Construction space: 145 x 145 x 175 mm, up to 1,800 mm on request

Technical data

Advantages

High component accuracy
High surface quality
Details can be depicted from 500 µm
Short production time
Wide range of polymers with different properties available

Disadvantages

Support structures required for production reasons
Generally more expensive than selective laser sintering
