By stereolithography or laser sintering

ARNOLD uses two different methods to produce prototypes: Stereolithography (STL/SLA) in combination with subsequent vacuum casting and laser sintering.


Stereolithography (STL/SLA) and vacuum casting

Due to this process, it is possible to produce models and samples very quickly. This allows the optimum checking of dimensions, construction, Shore hardness and simple functions.

From the 3D data, we create a master model (STL model). It is produced step by step by the targeted pouring and curing of a liquid UV-sensitive resin. This master model in turn is used to create a silicone mould from which vacuum castings can be produced using various casting resins whose properties and degrees of hardness come close to those of the material used for series production. As a result, many functions can be tested in advance. The findings are ultimately used to improve products or manufacturing processes.

Laser Sintering (SLS)

Laser sintering is mainly used to produce functional prototypes that can withstand high loads without special surface requirements. In this process, the powdery starting materials are locally melted by a CO2 laser and the product is built up layer by layer.
