Array really automates 3D printing by making it a hands off procedure, I can send a print from my computer at home and not have to come into the office at 9pm – the parts are just sitting there ready for me the next day.
Connor Reddington, Avid (a Lubrizol Company)
Students at all levels of education should have access to an Array. It is essential if we’re encouraging STEM education, design engineering thinking, prototyping, iteration – students should have a reliable 3D printer to make parts in the volumes they need.
Cody Soska, Technical Specialist at IDeATe
The ability to develop and produce custom plastic parts at scale, on our factory floor, is great for our business and new client acquisition.

Everything You Need to Know
Mosaic PEEK prints best with a heated chamber and proper bed preparation. Pre-drying the material helps ensure consistent extrusion and layer adhesion, and printing one part at a time can improve results. Post-print heat treatment can further enhance mechanical performance and dimensional stability.
Mosaic PEEK is an engineering-grade polymer designed for extreme mechanical, thermal, and chemical demands. Its combination of strength, stiffness, and toughness makes it suitable for replacing metal components in aerospace, medical, automotive, and industrial applications where reliability is critical.

Yes. Mosaic PEEK offers exceptional resistance to chemicals, oils, solvents, and aggressive industrial fluids. It remains dimensionally stable and mechanically reliable even in harsh chemical environments, making it well-suited for pumps, seals, fluid-handling components, and chemically exposed fixtures.
Yes. PEEK is one of the most demanding materials in FFF 3D printing and requires tightly controlled conditions. Printing Mosaic PEEK reliably requires a heated chamber, and stable thermal management to achieve proper layer bonding, dimensional accuracy, and mechanical strength. It is recommended for advanced users working with high-temperature systems.
