MattFlex 40D

Matte flexibility

MattFlex 40D is another proposal from Fiberlogy in the area of flexible 3D printing materials (e.g. TPU- or TPE-like filaments). Unlike the much-appreciated FiberFlex, this filament is distinguished by its matte finish, but like FiberFlex, it is easy to print and allows efficient printing at speeds of up to 60 mm/s without compromising print quality.

The matte finish allows you to achieve an attractive model appearance, especially 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 numerous 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 make this filament a versatile material for 3D printing.

How to print?

The following parameters are only suggested print settings for this material. To ensure the best print quality, it is necessary to choose the appropriate settings for a specific printer and printing conditions.


Nozzle Temperature 210-230°C
Bed Temperature 50-70°C
Closed chamber not required
Fan 50-75%
Flowrate 105-110%
Printing Speed < 60 mm/s
Surface glass, masking tape
Retraction (direct) 1-2 mm
Retraction Speed 10-30 mm/s
Drying conditions 60°C / 4h
Notes To remove the print easier, it is recommended to heat the bed to 110°C
