Filaflex 95 Foamy from Recreus is a cutting-edge flexible TPU filament that employs dynamic foaming technology to produce lightweight, elastic parts with a Shore hardness of 95 A. What’s more, Filaflex 95 Foamy enables 30-40% material savings by reducing part weight and density, maximizing efficiency and productivity, especially in high-volume manufacturing.

The parts 3D printed in one of the vibrant colors available exhibit a smooth, matte finish and a texture that is soft and pleasant to the touch, making it an excellent choice for applications that demand both functionality and aesthetic appeal.

Dynamic foaming technology

Just like the Filaflex Foamy and PLA LW filaments from Recreus, Filaflex 95 Foamy contains a foaming agent evenly distributed throughout the filament, activated at high temperatures.

This activation gives the printed material its distinctive foamy texture and appearance. Parts 3D printed with the Filaflex 95 Foamy filament are more rigid than those made with Filaflex Foamy, yet maintain a lightweight and low-density profile. This combination of properties makes Filaflex 95 Foamy an ideal choice for projects requiring flexibility and reduced weight.

Modifiable Shore hardness

Filaflex 95 Foamy has an initial Shore hardness of 95 A, perfect for applications needing both elasticity and fatigue resistance. Adjusting printing parameters can achieve different levels of hardness and elasticity.

The Shore hardness of the parts will vary depending on the printing parameters

For example, using an extrusion temperature of 240-250 ºC and a flow setting of 60-70 % results in a Shore hardness of approximately 70 A, with increased elasticity and a foamy texture. In contrast, higher flow values (90-100 %) will produce a higher hardness with less elasticity and no foamy texture. Thus, by tweaking temperature, flow, and speed, users can obtain various finishes within the same part.

Variable color

Another distinctive feature of Filaflex 95 Foamy is its ability to alter the color tone of printed parts through print settings. At lower extrusion temperatures, the printed part will exhibit a more intense color.

Applications

This versatile TPU filament is suitable for a wide range of applications, including prosthetics and orthopedic supports, where its variable hardness and soft touch are ideal for custom medical devices. It is also well-suited for footwear, such as insoles and soles, as well as ergonomic tools and bicycle grips, which benefit from its flexibility and adaptability. Furthermore, Filaflex 95 Foamy is used in automotive parts like bumpers and gaskets, and in protective components that cushion impacts or absorb sound, demonstrating its broad utility in various industries.

For optimal printing with Filaflex 95 Foamy, recommended settings include a printing temperature of 245-255ºC, a speed of 20-40 mm/s, and a layer height of 0.2 mm. Retraction speeds should range from 35-50 mm/s with a distance of 2.5-6 mm, and travel speeds of 160-200 mm/s. Flow rates between 60-100% will vary depending on the desired part properties. It is advised to refer to the product's technical datasheet for more detailed guidance, and general tips on printing with Filaflex filaments are available on the manufacturer's website.

To prevent moisture absorption, store Filaflex 95 Foamy in a dry, sealed plastic bag with a filament drying capsule or in an airtight container. Inline filament dryers are recommended during printing, and if needed, drying the filament at 40-45ºC for at least 5 hours before printing will ensure optimal print quality.
