Hot lithography is a laser-based 3D printing process that uses a special heating and coating mechanism to additively manufacture precise plastic parts with good mechanical properties. The hot lithography technology allows highly viscous and highly molecular starting materials to be processed.
Patented hot coating technology
The resins are heated to 120° C to bring them to a workable state. A special hot layer technology allows the temperature to be regulated precisely and individually during the various process steps. This prevents overheating and thus uncontrolled polymerization of the material.
The 3D object is built up in layers 50-100 µm thick. A new layer is created by immersing the partially manufactured component in the liquid resin layer and a laser exposes and thus polymerizes the areas that are materialized. The combination of liquid raw material and high-precision laser polymerization enables unbeatable precision, resulting in uniquely smooth surfaces.
