STEREO-LITHOGRAPHY (= SLA OR STL) is a form of additive manufacturing technology that creates parts in a layer by layer step using a process by which light causes chains of molecules to link together. The creation of highly complex geometrics – even with undercuts – is no problem, even though this is not possible with conventional production.
Scope for SLA
Design models and functional models with enhanced requirements regarding surface quality at low to medium mechanical stress and no thermal requirements (< 45°C)
Pieces of artwork
Master pattern for follow-up processes (vacuum casting, RIM)
On leaving the machine the components have a good, fairly smooth surface.
By appropriate finishing the components become very smooth and the transparent material becomes clear (after applying clear coat).
Post processing like lacquering or coating is particularly opportune.
Materials
Acrylic- und epoxy resin-based materials, in part with ceramic fillers, with variable mechanical and thermal properties in different shades:
clear, white and grey.
