Recreus Filaflex Foamy Denim, 1,75 mm / 600 g

Filaflex Foamy from Recreus is a flexible material that combines TPU with dynamic foam technology. A special foaming agent is distributed throughout the filament and activates on contact with high temperatures. The result: a foamy texture for lightweight and flexible printed parts with a smooth surface texture, low density and low weight.

With specific printing parameters to achieve certain material properties

The flexible material has an initial Shore hardness of 78A, but can also achieve a lower hardness of 51A by adjusting certain parameters (temperature, flow rate, speed). While the filament expands at a low flow rate, foams more and achieves a lower Shore hardness, a higher flow rate produces less elastic printed parts with a higher Shore hardness but without a foamy texture.

This not only allows specific material properties to be generated, but also maximises productivity, as between 30 % and 40 % more can be printed with the same amount of material - depending on the set flow rate.

The colour tone of the printed part can also be adjusted when setting printing parameters. While lower temperatures produce more intense colours, higher temperatures activate the foaming agent, which brings out brighter colours.

Possible applications:

• Printing of shoes (both whole and parts and components such as insoles and soles),
• Production of bicycle handles, bicycle seats or other devices,
• Production of flexible objects and parts for the automotive industry (bumpers, seals, tyres, grippers),
• Manufacture of knee pads and elbow pads,
• Production of protective elements or parts for sound absorption.
