A Vienna-based startup turns 3D printing up to 120 °C

Precision, surface quality, and good material properties are essential in additive manufacturing. However, current processes sometimes falter in one of these areas. Vienna University of Technology and its spin-off Cubicure want to remedy this with its solution Hot Lithography.

Vienna University of Technology believes that it has to date been difficult to satisfy all the technical needs of industry at once. One example here is stereolithography (SLA), a process by which liquid resin is selectively solidified. The materials used are, however, brittle and unable to maintain their form well at high temperatures. Innovative resins from spin-off Cubicure aim to resolve such problems, whereby the solution lies in the processing temperature: In SLA, the areas to be solidified are processed using a special laser; this triggers a chemical reaction, which solidifies the resin in the right places. Cubicure enables this process to take place at temperatures of up to 120 °C, thereby also enabling the use of highly viscous special resins. Hence the name: Hot Lithography . As a result of this process, the resins are hard, heat-resistant up to 75 °C, and shock-resistant.

The company sees great potential for the use of this process in sectors such as car manufacturing, aerospace, the electrical and electronics industry, and mechanical engineering. Cubicure will be co-exhibiting the technology with the Austrian Chamber of Commerce at the Hannover Messe 2018, in Hall 5, Stand D18 . Other providers are also working to optimize 3D resins. In 2017, for instance, Hennef-based company DruckWege launched its own UV-sensitive synthetic resin on the market. This resin is tailored to DLP light sources and, according to the manufacturer's specifications, enables “ultra-fast” hardening processes of 5 to 6 seconds for layers of 150 μm.
