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 PEKK prints best with a heated chamber and proper bed preparation. Pre-drying the material helps ensure consistent extrusion and strong layer adhesion, and printing one part at a time can improve results. Adjust settings as needed based on part geometry to achieve optimal performance.

Mosaic PEKK is engineered for extreme performance in demanding, safety-critical environments. Its combination of strength, stiffness, thermal stability, and chemical resistance, along with improved printability and durability, makes it ideal for aerospace, industrial, and advanced engineering applications.
Mosaic PEKK offers excellent thermal stability, maintaining structural integrity under continuous high-temperature loads. It is well suited for automotive under-hood components, aerospace brackets and housings, high-temperature tooling, and other demanding industrial applications.
Yes. Mosaic PEKK offers exceptional resistance to harsh chemicals, oils, and solvents. Its stability under corrosive conditions makes it well suited for environments such as oil and gas, chemical processing, industrial manufacturing, and fluid-handling applications. Parts retain their strength and dimensional stability even with prolonged chemical exposure.
While easier to print than PEEK, Mosaic PEKK still requires advanced hardware, including a high-temperature nozzle and a heated chamber, to ensure strong layer adhesion, dimensional accuracy, and high-quality surface finish.
