MattFlex 40D

Matte flexible filament for 3D printing

MattFlex 40D is our another proposition from Fiberlogy in the area of flexible 3D printing materials like TPU filaments. This matte flexible filament is distinguished by its unique non-gloss finish. However, printing with MattFlex 40D is still just as easy as with FiberFlex 40D. Moreover, it is also possible to achieve higher printing speeds, up to 60mm/s without compromising 3D print quality. The matte finish of this flexible filament allows you to achieve an attractive finish, where a lower gloss is expected. MattFlex 40D makes it easy to hide layers, giving your print a perfect surface without any need for further processing.

Great looks and ease of printing are not all that MattFlex has to offer. This rubber-like filament is ideal for many applications, both domestic and industrial. High impact strength, elasticity (up to 6 times) and compressive resistance (up to 50%), as well as resistance to chemicals and low temperatures. All this makes this matte, flexible filament a versatile 3D printing material.

The matte finish of 3D printing is not the most important to you? Check out our offre of non-matte flexible filament. Our offer includes 3d printing materials from the FiberFlex family with various hardnesses on the Shore scale. Try out Fiberlogy FiberFlex 40D and Fiberlogy FiberFlex 30D.
