The aim of Cubicure is the additive manufacturing of polymer components with outstanding impact strength and heat deflection temperatures while at the same time, having the highest possible surface quality. During theoretical considerations about suitable chemical compounds for those photopolymer systems, it was evident that the resulting substances will have a very high viscosity at room temperature and thus cannot be processed in previously available SLA systems. From this, Cubicure started developing a special 3D-printing concept which is applicable for processing highly viscous chemicals.Since the viscosity of many fluids is highly temperature dependent, the concept of a heated 3D-printing process was implemented. The laser exposure process known from SLA systems has been combined with a special, newly developed and also heatable coating system.The multiple patented technical solution to this process challenge was published as Hot Lithography.The core of the technology is a specially developed and patented heating and coating mechanism which can process resins and pastes of the highest viscosity with maximum precision at working temperatures of up to 120°C.For material exposure, high-precision laser scanner systems are used. Available light wavelengths are 375 nm in the UV range and 405 nm in the visible blue range.Hot Lithography enables the use of high-molecular-weight chemical systems for precision 3D-printing, thereby creating components of unsuspected material quality.
Plastic components for industrial use require good thermo-mechanical material properties like those of engineering thermoplastics such as Polypropylene (PP) or acrylonitrile-butadiene-styrene ...
