Lithoz Unveils Three New Ceramic Materials and CeraFab S320 at Ceramitec 2026

Lithoz is heading to ceramitec 2026 in Munich with a full production-scale push: three upgraded ceramic slurries and a live demonstration of its large-format CeraFab System S320, all aimed squarely at industrial serial manufacturing rather than the prototyping use cases that have historically dominated ceramic additive manufacturing conversations.

The Vienna-based LCM specialist announced the lineup on March 9, with the show running March 24–26. The three materials span the company's existing LithaLox and LithaCon families, but the upgrades are substantive enough to matter on the shop floor.

The revised LithaLox alumina formulation pushes solid loading to 55 vol%, a figure that directly reduces shrinkage variation during sintering and produces a smaller, more uniform shrinkage ratio. Printable wall thicknesses now reach up to 12 mm. Lithoz frames this as combining the mechanical properties of high-purity aluminum oxide with the processing ease of more versatile ceramic variants, which in practice means fewer headaches when integrating it into existing industrial workflows.

The second material, a new LithaCon zirconia variant, gets qualitative but meaningful improvements: better fracture toughness, improved cleanability, and a significantly increased Weibull modulus. That last point is the one to watch for production engineers. A higher Weibull modulus means tighter statistical reliability across a batch of brittle ceramic parts, which is the kind of consistency that actually moves the needle on yield rates. Lithoz specifically flags this formulation as suited for threaded geometries like endosseous dental screws, where dimensional precision under load is non-negotiable.

The third material is where the numbers get serious. LithaCon ATZ, an alumina-toughened zirconia designated as medical-grade, supports wall thicknesses up to 17 mm and a measured bending strength of 993 MPa. Lithoz ties production of this material to its ISO 13485-certified quality management system, positioning it for dental implants, surgical tools, and broader MedTech components. ATZ combines the hardness and wear resistance of alumina with the toughness of zirconia, and at 993 MPa, the bending strength figure puts it in genuinely competitive territory for load-bearing implant applications.

The CeraFab System S320 will also be running at the Lithoz booth. Per the company's earlier technical release from March 2025, when the S320 was introduced to the US market at RAPID+TCT, the printer delivers a five-fold increase in build platform capacity compared to the S65 model, prints at 60 μm resolution, and includes Digital Surface Enhancement software for improved surface precision. Those specs, combined with the expanded platform, make it the throughput argument Lithoz needs to back up the serial-production positioning.

The parts on display at ceramitec will make the cross-industry pitch concrete. Visitors can expect to see 46 ceramic casting cores for single-crystal turbine blades used in next-generation aircraft engines, 132 zirconia dental implants, aluminum nitride cooling plates, otoplastics for hearing devices, and a 15-inch ALD gas distribution ring for the semiconductor industry. That last part already has a documented production story: Alumina Systems printed 20 individual segments for a 15-inch diameter alumina gas distribution ring designed by Plasway on a single S320 build platform. According to Lithoz and collaborator Dr.-Ing. Holger Wampers, Managing Director of Alumina Systems, "working on this atomic layer deposition ring together with Lithoz, we could create new generations of ring structures to enable higher geometric stability and accuracy." Lithoz claims the ceramic version achieved an uptime increase from 1 to 9 months compared to conventionally manufactured metal rings, though that figure comes directly from company press materials and has not been independently verified.

Lithoz describes this entire ceramitec push as a "manifesto for serial production in ceramic 3D printing," backed by what it calls a global Ceramic 3D Factory network of LCM contract manufacturers and research institutes. The strategy is to give OEMs a ready-made adoption path, not just a printer and a slurry. Whether the materials data and that network hold up under the scrutiny of actual qualification processes is the question the MedTech and aerospace sectors will be asking well after the Munich show closes.
