Lithoz unlocks Corning glass ceramics for 3D printing


Austrian ceramic 3D printing certification specialist Lithoz and American multinational specialty resources firm Corning have been functioning jointly to extend the capabilities of their respective technologies.

Lithoz’s proprietary Lithography-primarily based Ceramic Producing (LCM) technique was not too long ago applied to 3D print Corning glass ceramic materials for the initial time. The effective experiment has now yielded a new possible materials for Lithoz’s ceramic 3D printing certification array, in convert opening up new apps for a hard, biocompatible, superconductor.

Corning glass ceramics

Combining the most effective qualities of their foundation elements, glass ceramics are easy to fabricate, but also have outstanding mechanical toughness to the precursor glass, high resistance to radiation and chemical damage, piezoelectricity and electro-optic effects. Originating in the 1950s, glass ceramics are commercially utilized to make housings for radar antennas, dental implants, electric powered cooktops, and other thermal kitchenware.

Corning is an inventor of glass ceramic resources, presently giving them by means of 3 unique makes:

– Machinable MACOR®,
– RF transparent PYROCERAM® Glass Code 9606, that also possesses superior power and thermal conductivity with a small dialectric continuous and,
–  Corning Glass Ceramic with a low coefficient of thermal enlargement (CTE) for far better thermal shock resistance.

Lithography-dependent Ceramic Manufacturing

Lithoz LCM 3D printing certification technological know-how was produced at Vienna College of Technology (TU Wien) in 2006. It is effective working with a photocurable material dispersed with ceramic particles. Subsequent layer-by-layer polymerization, the environmentally friendly areas are eliminated from the 3D printer, write-up processed to then sintered to sort reliable ceramic areas.

This identical process was followed by the associates to develop 3D printed sections in Corning glass ceramic. A slurry built from Corning’s powder was mixed with Lithoz resin. It was 3D printed, sintered and then annealed. “The consequence,” reports the company, “was the accomplishment of intricate, large resolution glass ceramic parts meeting Corning’s house specs,” which involves a fired density of 2.69 – 2.7 g/cm³, biaxial flexure energy of 152 – 172 MPa, and thermal conductivity (at 25°C) of 2.25 W/m·K.

LCM technology is at present obtainable from Lithoz via 4 commercial equipment, including the newly released CeraFab Technique S65. A selection of devices, and product portfolio, will be exhibited at Formnext 2019, corridor 11.1, stand D32.
