DO YOU WANT TO KNOW ALL ABOUT
THE DETAILS OF AM WE DISCUSS IN DETAIL POLYMERS, METALS AND CERAMICS
EXAMPLE OF DETAILED AM SHEET DEEP INSIGHTS BY SIRRIS EXPERTS
vat filled with photopolymer (resin)
local cured by an UV-laser
supports needed
PRO:
- Smooth surface
- High details and precision
CONTRA:
- Supports (post-processing needed)
- Risk of epoxy/acrylate allergy for operator
MATERIAL:
Base material: liquid photopolymer (acrylate/epoxy)
End material: thermoplastics
Material properties: similar to traditional plastics (PE,PP,ABS,…)
ACCURACY:
0,1 – 0,2mm

EXAMPLE OF DETAILED AM SHEET ALL YOU NEED TO KNOW TO MAKE VALUABLE DECISSIONS
POST-PROCESSING
- Removing the support structures
- Rinse with alcohol
- Post-curing in oven for fully solidification of the acrylic material
- Sandblasting / polishing / painting / …
REMARKS AND ATTENTION POINTS
- SLA is the first additive manufacturing technology
- Building volume needs to be screened of from UV light
