FibreTuff hand Vosfox

Vosfox Medical printed a hand model using FibreTuff material. The hand model consists of 27 bones that were assembled together. The bones of this anatomical hand model were successfully printed with the Ultimaker 2+ 3D printer. After finding the proper nozzle temperature for smaller bone models, homogeneously coloured bones were printed. Thanks to the cortical bonelike drilling properties of 3D printed FibreTuff I, the separate bones could be connected by drilling small holes that fit iron wires, resulting in this full-scale anatomical hand bone model.


Fibre Tuff is a composite material that has bone-like properties. It is possible to drill the material and set screws, with excellent screw retention. The material has a tensile strength similar to nylon (PA 11 or 12). This makes the material ideal for model printing.

The material is biocompatible. It has passed the USP Class VI testing. This includes

  1. Acute systemic toxicity test; a systemic injection test using different types of extracts. Measures toxicity and irritation
  2. Intracutaneous injection test with different extracts. Measures toxicity and local irritation in subdermal tissue
  3. Implementation of a test strip for several days. Measures infection and irritation in muscular tissue.

FibreTuff models can be autoclaved, so the models can be used in the OR. The biocompatibility of the material and the possibility of sterilization make the material useful for surgical guides printing. With a non-toxic barium coating, the bone can be made bone-like radiopacity, making the material suitable as phantom material

Fibretuff models, surgical guides as well as the material (SLS powder, filament (1,75 and 2,80 mm) can be purchased from Vosfox Medical. Vosfox Medical has nearly ISO13485 certification and can produce in an ISO Class 7 Cleanroom.
