Overview

More and more individualised and complex parts increase the challenge of spare part procurement and the risk of shortages. It is a huge problem to maintain expensive and important appliances. Cubicure’s Hot Lithography technology fulfils all the key user needs, while Hachtel is the first pure industrial user of Hot Lithography, for additive manufacturing of functional components.

Stockpiling large volumes of spare parts and injection moulds after the series production ended is costly. In some cases, not even technical drawings of these parts exist and to restart conventional production without moulds is far too expensive. With an essential part missing, the whole appliance must be replaced or is out of order until alternatives are found. That’s not only a financial disaster for the affected businesses, but also has negative impacts on customer satisfaction, if e.g. regarding the mobility sector, trains are cancelled or promised delivery times cannot be met. Additive manufacturing (AM) can solve these problems and produce small batches cost-efficient, with short lead times, and without moulds or other individualised manufacturing tools. But conventional 3D-printing technologies are limited in their technical and economic capabilities.
By using high molecular and therefore highly viscous, high-performance photopolymers, unmet material properties can be achieved. The patented printing technology ‘Hot Lithography’ is capable of processing such viscous resins and exploits the high precision and surface quality of lithographic methods. Hachtel provides customers a complete integrated procurement solution: the digitalisation of the original part, engineering and part optimisation, cost-efficient additive manufacturing of high-quality parts and the subsequent and widely underestimated part qualification. Hachtel and Cubicure cover the complete integrated process chain from the digitalisation of the original part, up to the qualified, optimised and functional spare part produced by the innovative 3D printing technology Hot Lithography.
