Flexible 3D printing materials have numerous applications across a wide range of sectors, from customer goods and clothing/footwear to medical and automotive uses. The PolyFlex TPU95 filament from the Polymaker portfolio of high quality flexible materials is specifically engineered to work on most desktop FFF 3D printers.

With a Shore hardness of 95A, this thermoplastic polyurethane (TPU) can stretch more than 3 times its original length and withstand loads of up to 400 %. Parts 3D printed with the PolyFlex TPU95 have a soft rubbery feel and perform excellently in applications where high flexibility and durability are required.

Flexible materials are known to be problematic at the time of extrusion but with the PolyFlex filaments this is not the case. Polymaker's aim with these materials was to make 3D printing with flexible filaments easy and accessible for everyone. PolyFlex TPU95 is easy and undemanding to print (the use of a direct drive printer is highly recommended) and adheres well to a variety of surfaces without the need for a heated bed.

The additive manufacturing possibilities with the PolyFlex TPU95 filament are countless, for example in the 3D printing of wearables, fabrics, footwear. The color variety of the PolyFlex TPU95 filament will ensure that the needs of any project are met to create high quality parts. This filament is perfect for those who need to manufacture both on a small and a large scale with desktop 3D printers.

The PolyFlex TPU95 filament is delivered in a vacuum sealed bag with desiccant. Once opened, the filament should be stored properly to prevent it from absorbing moisture from the air. The best way to store filaments in a tightly sealed bag with desiccant, in a vacuum sealed container or in an intelligent filament container. During printing, the filament can be placed in PolyBox. If the PolyFlex TPU95 filament absorbs humidity, it should be dried before printing at 65 ºC for 8 hours in a filament dryer.

The manufacturer recommends printing PolyFlex TPU95 filament at 210-230 ºC on a bed heated to 25-60 ºC. It is recommended to print at a speed of 20-40 mm/s with the layer fan on. The best build surface for this filament is a glass surface with glue, Blue Tape or BuildTak. The recommended suppport material for PolyFlex TPU95 is PolyDissolve S1 or PolySupport.

It is highly recommended to wear standard safety equipment during the printing and post-processing of parts 3D printed with the PolyFlex TPU95 filament - safety goggles, gloves, breathing equipment and protective garments, according to needs.
