120 mm. Printed layers heights of 50 to 200 µm enable a balance between fine features and print time. LCM technology combined with LithaCore 450 material can yield incredibly impressive results and has been effectively utilized in the production of most recent casting core designs which can no longer be produced by conventional injection molding. 3D printing of cores is not just for prototyping, but also
viable for production. The productivity of the CeraFab S230 printer was studied for a core design with a volume of 10x32 mm in the build plane, and 90 mm tall. Production times as low as six minutes per core and 233 cores produced in 24 hours were achievable while still maintaining the desired level of product quality. Besides allowing the development of the most recent core
and shell designs, ceramic 3D printing delivers significantly faster time-to-market, as well as a shorter product life cycle. This process also bypasses the costly and laborious fabrication of molds required for injection molding, which would be a great benefit to the customer. Lithoz is headquartered in Vienna Austria, where the
CeraFab LCM printers and materials are produced, since the company’s founding in 2011.
In 2017, the US subsidiary,
Lithoz America, was formed in Troy, New York. Lithoz America conducts application development, CeraFab user support, and materials production for custom core materials. Lithoz America has been an affiliate member of ICI since 2017.
