Mosaic Flex (TPU) is a high-performance thermoplastic polyurethane designed for exceptional flexibility, toughness, and long-term durability. With its rubber-like elasticity, excellent abrasion resistance, and high chemical resilience, this filament is ideal for parts that must bend, compress, absorb impact, or perform reliably under repeated motion and wear.
What is Mosaic Flex?
Durable and easy to use. Explore Mosaic Flex’s material specifications and key properties below.
Mechanical Properties
Mosaic Flex offers high elasticity and toughness, with a 95A Shore hardness and a tensile modulus of 30.1 MPa. Its 347.8% elongation at break enables significant stretch without tearing, making it ideal for demanding, high-flex applications.
Thermal Properties
As a TPU-based elastomer, Mosaic Flex delivers stable mechanical performance across typical temperatures. While not suited for high heat, it maintains flexibility and integrity under normal ambient and light thermal loads.
Chemical Properties
Mosaic Flex is highly resistant to abrasion, oils, greases, and many industrial chemicals, making it ideal for components exposed to friction, repeated motion, or harsh environments. Its durability and wear resistance support long service life in demanding applications.

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 Flex typically prints best at slower speeds to help maintain consistent extrusion and reduce stringing. Proper bed preparation can improve first-layer adhesion, and adding stabilization or support features can help with tall or thin parts. While Mosaic Flex has low moisture sensitivity, proper drying and storage can help ensure reliable results.

No. While TPU can be more challenging than rigid materials, Mosaic Flex comes with pre-configured print profiles for Element and Array, so customers don’t need to manually tune settings. These profiles ensure reliable printing with consistent extrusion, smooth surfaces, and optimal part quality right out of the box.
Yes. Mosaic Flex is highly resistant to abrasion, oils, greases, and many industrial chemicals. This makes it excellent for high-wear applications such as seals, impact-absorbing components, and parts exposed to repeated friction or motion.
Mosaic Flex is ideal for gaskets, seals, ergonomic grips, vibration dampers, protective sleeves, shock-absorbing components, and any part requiring long-term elasticity and toughness. Its rubber-like behaviour and high durability make it suitable for both functional and industrial use.
