SLA - stereolitography

Stereolithography, SLA, is used when you need surface and dimensional accuracy and richness of detail. SLA is also optimal for design models and master pattrern for casting moulds. Prototypes can be tailored using different materials in order to achieve the desired transparency, flexibility or rigidity. In the case of design models, the parts are finished and coated so that they are as close to the final product as possible. We can also add different surface structures, graphics, prints or colours. SLA is just one of our rapid prototyping / additive manufacturing / 3D printing options.

SLA - technical data

The machine consists of a vat which is filled with a liquid epoxy resin. A building platform lowers down gradually into the vat. A UV laser hardens the material layer by layer according to the information in the sliced CAD file. Once the process is complete, the parts are removed from the platform, cleaned and then cured in an UV oven. Finally, agreed post treatment is done on the parts, e.g. finishing, blasting and painting.

Tolerance: min ± 0.1 mm plus ± 0.15% of dimensions. Smaller tolerances upon agreement.
The minimum X/Y axis wall thickness is 0.25 mm. The minimum Z axis wall thickness is 0.4 mm.
There is a risk of increased tolerances in the case of cutted and bonded parts.
