Advantage of the procedure
- at present the most accurate rapid prototyping progress
- manufacturing of component parts with high complexness
- manufacturing of cavities possible
Examples of use
- complex component parts usable as samples of design or as samples for construction check-up
- Primal model for following procedures vacuum casting
Stereolithographic (STL) is a Rapid-Prototyping-Procedure that enables the contact-free manufacturing of models within a few hours.
Stereolithographic procedure converts 3D-data immediately into primal models. Stereolithographhic process is based upon in-layers-hardening of a liquid polymer caused by UV-laser light. The part emerges upon a construction pillar directly under the surface of a polymer bath. At first the laser beam marks the outline of the part and hatches its cross-section afterwards.
After producing the first layer, featuring depending on demand 0,05 or 0,10 up to 0,15 mm layer thickness the part is being lowered by layer thickness into the fluid again. The surface is being rehumidified. Having finished construction activity the part is being taken from the stereolithographic facility. The construction pillar and residue of liquid polymer are being removed. Sterolithographic is the edelst and most widely-used Rapid-Prototyping procedure.
