For the additive manufacturing of plastic parts, numerous different production technologies are available. Due to insufficient
material properties or surface quality and precision, additively manufactured plastic parts have not made it from the position
as design models and prototypes to the industrial production of technical or medical parts as well as products of everyday
life. On one hand, good thermo-mechanical material properties like those of technical thermoplast (e.g. PP or ABS) are necessary
as components for industrial applications. On the other hand, geometrical properties, such as low surface roughness like injection
molded parts are crucial.
For producing parts with excellent surface quality, stereolithography processes (SLA) perform by far the best. However, the
big disadvantage of these technologies are the traditional material systems. Classical photopolymers are brittle and have
a low heat distortion temperature. Hence, they are subjected only to a limited extent for technical applications.
Cubicures newly developed photopolymers are exceedingly tough and have a high dimensional stability under heat. Those
properties can be obtained through highly viscous and sticky raw materials, which cannot be processed in commercial SLA machine
until now. Out of this, Cubicure developed its own additive manufacturing process, Hot Lithography, for the processing of
those poorly flowable material systems.
