Austrian ceramic 3D printing specialist Lithoz and American multinational specialty supplies firm Corning have been working collectively to increase the capabilities of their respective applied sciences.
Lithoz’s proprietary Lithography-based Ceramic Manufacturing (LCM) method was just lately used to 3D print Corning glass ceramic supplies for the primary time. The profitable experiment has now yielded a brand new potential materials for Lithoz’s ceramic 3D printing vary, in flip opening up new functions for a tricky, biocompatible, superconductor.
Corning glass ceramics
Combining the perfect properties of their base parts, glass ceramics are straightforward to manufacture, but additionally have superior mechanical toughness to the precursor glass, excessive resistance to radiation and chemical harm, piezoelectricity and electro-optic results. Originating within the 1950s, glass ceramics are commercially used to make housings for radar antennas, dental implants, electrical cooktops, and different thermal kitchenware.
Corning is an inventor of glass ceramic supplies, presently providing them via three completely different manufacturers:
– Machinable MACOR®,
– RF clear PYROCERAM® Glass Code 9606, that additionally possesses excessive power and thermal conductivity with a low dialectric fixed and,
– Corning Glass Ceramic with a low coefficient of thermal growth (CTE) for higher thermal shock resistance.

Lithography-based Ceramic Manufacturing
Lithoz LCM 3D printing expertise was developed at Vienna College of Know-how (TU Wien) in 2006. It really works utilizing a photocurable materials dispersed with ceramic particles. Following layer-by-layer polymerization, the inexperienced components are faraway from the 3D printer, submit processed to then sintered to type strong ceramic components.
This similar course of was adopted by the companions to supply 3D printed components in Corning glass ceramic. A slurry comprised of Corning’s powder was combined with Lithoz resin. It was 3D printed, sintered after which annealed. “The end result,” stories the corporate, “was the achievement of complicated, excessive decision glass ceramic items assembly Corning’s property specs,” which features a fired density of two.69 – 2.7 g/cm³, biaxial flexure power of 152 – 172 MPa, and thermal conductivity (at 25°C) of 2.25 W/m·Ok.
LCM expertise is at present obtainable from Lithoz via 4 industrial machines, together with the newly launched CeraFab System S65. A spread of methods, and materials portfolio, might be exhibited at Formnext 2019, corridor 11.1, stand D32.
