Stereolithography (SLA) is suitable for visualization models where there are high demands on surface finish and detail. SLA is a resin-based process where liquid is hardened by one or more light beams into the desired shape. The quality of the surfaces is already very high immediately after printing, but can be further improved to achieve transparent or high-gloss results for chromating and varnishing of various kinds. The materials for SLA are thermoplastics, which means that they are relatively brittle and sensitive to UV light and moisture. Other methods for 3D printing that we work with include: SLS Printing.

SLA (Stereolithography) is one of the most popular 3D printing techniques used to create complex and precise objects. In SLA printing, a UV laser is used to harden a photosensitive resin in a layer-by-layer process. When the resin has hardened, they are joined into a 3D object.
SLA printing is one of the most used techniques in 3D printing, and offers opportunities to create complex and precise objects with high speed and reliability. With a wide palette of finishing and a fast process, SLA printing is a powerful tool for prototyping and making models during the product development process.
