How to print with Ultimaker TPU 95A

Ultimaker TPU 95A (thermoplastic polyurethane) is a semi-flexible material that can be used in a wide variety of engineering applications where performance is more important than aesthetic qualities. Although most flexible filaments are usually difficult to print, Ultimaker TPU 95A is optimized for easier and faster printing without negatively affecting layer bonding.

Note: The information provided here applies to Ultimaker TPU 95A, similar quality cannot be guaranteed with third-party filaments.


Ultimaker TPU 95A is supported on the Ultimaker S5, Ultimaker 3, and Ultimaker 2+. On these printers, it is compatible with the print core / nozzle sizes as shown in the below overview. You will need an AA print core to print TPU 95A on the Ultimaker S5 and Ultimaker 3.

Note: Ultimaker TPU 95A is not supported on the Ultimaker 2 Go, Ultimaker 2 (Extended), Ultimaker Original+, and Ultimaker Original

Because TPU 95A is prone to oozing, we don’t officially support printing TPU 95A in combination with other materials. However, on the Ultimaker S5 and Ultimaker 3, TPU 95A can be printed experimentally in combination with PVA, Breakaway, ABS, Nylon, PC, or another color of TPU 95A. Be aware that dual-extrusion combinations with TPU 95A may result and stringing and blobs on the surface of the print.

Recommended settings and configuration

Note: Always use the latest version of Ultimaker Cura and make sure that your 3D printer is updated with the latest firmware version to include the correct material profile for Ultimaker TPU 95A.


For printing TPU 95A a nozzle temperature of 220 - 235 °C is recommended. Furthermore, the TPU 95A profiles are optimized to print on a cold build plate on the Ultimaker S5 and Ultimaker 3, and on a build plate of 70 °C on the Ultimaker 2+.

Note:  The correct temperatures are automatically used based on the printer, nozzle size, and profile you select in Ultimaker Cura.


In most instances, extra adhesion is not necessary for a successful print, but we always advise applying a thin layer of glue (included in the accessory box of your Ultimaker) to the glass plate for the best adhesion.

Note: Do not use the adhesion sheets for Ultimaker TPU 95A. The adhesion is so strong that the sheet will tear after the removal of the first 3D print.

Glue application build plate adhesion method

A brim is the default build plate adhesion type in the Ultimaker TPU 95A print profiles in Ultimaker Cura. A brim consists of extra lines printed around the perimeter of the initial layers of your model. This ensures reliable adhesion to the build plate.

After printing, it’s very easy to remove the print from the build plate after cooldown.

Print environment

Ultimaker TPU 95A is not prone to warping or delamination, and prints reliably without additional accessories. However, you can try the front enclosure included in the Advanced 3D Printing Kit (for the Ultimaker 2+ or Ultimaker 3) to obtain more consistent and reliable results.

Furthermore, TPU 95A requires a relative humidity of below 50% when printed.

Health and safety

Ultimaker TPU 95A is safe to print when using the recommended temperature settings listed above. To ensure a comfortable and healthy working environment, we recommend 3D printing in a well-ventilated area.
