ROSA-Flex 96A is a technical TPU filament. It can be used wherever elements resistant to chemical reagents and mechanical damage are needed. Printouts made of this material can be squeezed and stretched many times without damaging the original shape. The material is characterized by both excellent interlayer adhesion and adhesion to many work surfaces.

Application examples:

• gaskets, bumpers, anti-vibration dampers / feet, housings;
• orthoses;
  
• smartphone cases;
  
• components for drones;
  
• components for RC cars.
  

ROSA-Flex 96A is a thermoplastic polyurethane (TPU) for intermediate users of 3D printers. It’s perfect for people who want to start their adventure with printing flexible materials. ROSA-Flex 96A filament is hard enough to be printed even on printers with Bowden feeding. In addition, it does not require a closed chamber and will easily stick to many work surfaces (e.g. glass, smooth PEI, textured PEI).

After selecting the optimal printer settings, the prints show excellent adhesion and resistance to mechanical damage. They can be compressed and stretched many times without permanently disturbing their original shape. Moreover, dipping them in vinegar or engine oil does not cause any visible changes. The full chemical resistance table can be found here (“downloads” section).

This version of  ROSA-Flex 96A filament has a unique ability. It can glow in the dark! You can create parts that will provide protection and be visible in places depraved of light. Simply expose it to natural or artificial light and it will emit a phosphorescent, green glow in the dark.

Recommended printing parameters:

• extrusion temperature 210-250°C
  
• bed temperature: 50-70°C
  
• fan: 0-100% (depends on the geometry of the model)
• print speed: 15-50 mm/s (we recommend starting slowly and gradually trying to increase the speed)
• compatible bed surfaces: glass, smooth PEI, textured PEI.

Filament can be printed on printers with Direct and Bowden feeding. It does not require a closed chamber. The material has good adhesion to the above-mentioned working surfaces, but in case of problems, we recommend the use of adhesive agents.

Problems with extruding the filament? Try this:

• loosen the screw that adjusts the level of pressure of the knurl to the filament feed roller
  
• reduce the print speed
  
• install a PTFE tube (photo)
