Our Proprietary Technical Ceramics

SINTX began printing ceramics in 1998, but our offerings have grown significantly since that time. Beginning in 2016, SINTX became a leading supplier of ceramic resins in the 3D printing market. Our proprietary blends of alumina, silica, and zirconia are optimized for stereolithography 3D printing. This advanced additive manufacturing technique utilizes digital light projection (DLP) technology to cure our ceramic-filled resins into 3D printed objects directly from a digital file. In addition to supplying our own production-ready resins, we also develop custom ceramic resin formulas to satisfy your unique printing objectives. These resins are specifically engineered by our team of ceramic engineers to print efficiently with high resolution and sinter to high density.

Alumina

Alumina is a widely used technical ceramic because it is a lower-cost material with excellent mechanical properties. Our proprietary, high-density alumina is the result of years of R&D and is specifically tailored to applications demanding high hardness, corrosion resistance, thermal stability, and electrical insulation.

Silica

Silica is renowned for its exceptional thermal shock resistance and chemical resistance, making it ideal for printing cores and cored molds for precision investment casting. Our unique formulation has been successfully used to cast single crystal turbine blades among a host of other applications.

Zirconia

Zirconia is known for its mechanical strength, fracture toughness, wear resistance, and thermal shock resistance. Though commonly used in dentistry for fabricating oral prosthetics, zirconia is gaining recognition as a vital structural ceramic for the manufacture of technical components that can withstand high stress and extreme thermal conditions.

FLEX-SN PEEK For Biomedical 3D Printing

FLEX-SN PEEK is a novel composite of implantable grades of silicon nitride and PEEK now available as a filament for 3D printing using the fused filament fabrication (FFF) method. This material represents a significant leap forward by blending silicon nitride’s favorable biocompatibility, tissue integration, and resistance to bacterial biofilm formation with PEEK’s well-known versatility and bone-like mechanical properties. Recent research has demonstrated printed FLEX-SN PEEK’s ability to resist colonization by common orthopedic bacteria and to be printed into implantable devices that far exceed industry mechanical property requirements⁷⁴. Further, devices printed using this material may be printed in-clinic without the lead times and heavy equipment requirements traditionally associated with ceramic processing.

Streamline Development with Stereolithography 3D Printing

Faster to Market for Ceramics

In an era where speed to market is critical, stereolithography 3D printing (SLA) offers a competitive advantage in the product development lifecycle. This advanced technology streamlines the path from digital design to functional prototype, significantly reducing development time and costs compared to conventional ceramic manufacturing techniques. Stereolithography's capability to adjust designs with agility, without the need for extensive tooling, positions it as a preferred choice for ramp-up production or niche product commercialization, enabling quick functional testing of ceramic prototypes and early assessment of market acceptance.

Rapid Prototyping

With decades of experience with ceramic 3D printing, SINTX has established a reliable, cost-effective process for rapid prototyping and parallel design iterations which accelerates development and ensures consistency in every prototype, driving your innovations forward with unmatched efficiency.

Lower Cost

Ceramic 3D printing eliminates the need for expensive mold construction and tooling costs associated with typical ceramic manufacturing techniques. Multiple prototypes can be made simultaneously, reducing cost per design iteration, making even the most intricate designs economically feasible.

Reduced Time to Market

Through rapid prototyping and by eliminating the need for tooling and mold construction, additive manufacturing significantly reduces the development cycle of ceramic components. By expediting the development phase, we help you achieve a market-ready product faster, giving you a competitive edge.
