CERAMIC RESINS & FILAMENTS
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.
OUR PROPRIETARY TECHNICAL CERAMIC RESINS
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.
SILICON NITRIDE FILAMENT FOR BIOMEDICAL 3D PRINTING
FLEX-SN PEEK
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.
