Lithoz unveils laser-induced slip 3D printing for large ceramic parts


Lithoz GmbH has finally unveiled details of its new CeraMax Vario V900 3D printer ahead of its debut at ceramitec later this month.

Based on the ceramic 3D printing expert’s new Laser-Induced Slipcasting (LIS) technology, the machine has been designed for the production of large parts (in a build area of ​​up to 250 x 250 x 290 mm) with thick walls and full densities using both oxide and non-oxide ceramics, including dark ceramics such as the highly sought-after silicon carbide, a notoriously difficult material to process with additive manufacturing.

Lithoz, which celebrated its 10th anniversary last year, explains that LIS works with water-based industrial suspensions with a very low organic binder content and that the machine has the capacity to apply up to 1000 μm. of mud per layer in less than a minute. With a water-based slurry solution, the process can completely absorb the light from the laser beam, opening up opportunities for new materials, and through a simplified debinding process, parts with greater wall thicknesses, this which, according to Lithoz, was previously not possible with current ceramic 3D printing solutions, can now be achieved. Additionally, green parts printed with the CeraMax Vario V900 can be machined without any restrictions, meaning they can be easily reintroduced into the traditional ceramic workflow.

Hardware-aware, the accompanying CeraMax Vario software offers database-supported storage and management of all process data, and can be upgraded to enable better parameter control and real-time process monitoring via remote video transmission.

While the Austrian 3D printing company says its flagship lithography-based ceramic manufacturing technology will remain the gold standard process for ultra-precise ceramic parts with thin features, it describes the CeraMax Vario V900 and LIS as a “new era” and an “ideal technological entry”. dot’ for newcomers to ceramic 3D printing.

The company will present examples of components manufactured using the new system at ceramitec from June 21 to 24.
