Sinterit Flexa Bright prints white on a small SLS 3D printer

In selective laser sintering (SLS) technology, printing white has usually been associated with big, industrial machines. Sinterit, the first manufacturer of desktop SLS 3D printers, has addressed the situation by creating Flexa Bright the first TPU material that prints as close to white as possible, while also preserving the material’s properties.

Flexa Bright is a functional rubber that can be printed with two levels of hardness, depending on the application, and can be used when a more aesthetic outcome is essential.

Sinterit co-founder Konrad Glowacki enthused: “We love our grey and black powders, which were a kind of benchtop SLS status quo for so many years now. But with this white material we are opening our products for a whole new range of applications, especially in medical, dental, or the fashion industry.”

Flexa Bright properties and uses

A rubber-like product, Flexa Bright has outstanding elongation with a break-point of about 317[%], and a tensile strength of 10[MPa], according to PN-ISO 37:2007. With an average hardness value of 79 in Shore type A scale by PN-EN ISO 868:2005, it is classified as a medium hard material. The water absorption of Flexa Bright is about 3%, according to PN-EN ISO 62:2008.

Printed on the Sinterit Lisa systems Flexa Bright is suitable for prototyping fabrics, clothes, or for creating items needed in healthcare, especially pre-surgery models and guides, and training printouts. It also can be used in architecture and prototyping.

The company exhibiting at Formnext in Frankfurt, Germany (from November 13-16th, booth G41, Hall 3.1) and will be demonstrating its SLS additive manufacturing system. To schedule a meeting with Sinterit's team or get a free ticket for Formnext, visit
