Pro3Dure GR-20 MJF: hemocompatible certified 3D printing resin


Pro3dure Gr-11 is a biocompatible 3D printing resin for the generative production of customized impression trays. Due to its high reactivity, build styles with up to 300μm z-height can be achieved in order to be efficient in the laboratory. The material is available in clear transparent color.


Pro3dure´s GR-20 MJF is a biocompatible and hemocompatible 3D printing resin for the generative fabrication of oral and maxillofacial surgery devices.

GR-20 MJF hemocompatible 3D printing resin parts can be sterilized using plasma, gamma rays, ethylene oxide or an autoclave. Moreover, the material is resilient against disinfectants. As the first of its kind it offers a broad range of applications in every operation room

How to use

  • GR-20 MJF  bottles should be well shaked before use (fig 1).

  • Make sure that GR-20 MJF material is temperature adjusted up to 23 °C to 30 °C.

  • Carefully pour GR-20 MJF into the vat of the image projection unit (fig 2).

  • Bubbles can be removed with a cleaned spatula or by a recoater routine.

  • If it is possible, always store a bottle GR-20 MJF in your production unit in order to avoid temperature differences during refilling.

  • For the build parameter adjustment please refer to the machine data sheet.

  • After the build process is finished a direct post treatment is recommended.

  • If this cannot be guaranteed leave the produced objects in the liquid GR-20 MJF resin.

  • After cleaning of the parts with isopropanole ≥ 97 % (approx. 3-5 min. in an ultrasonic bath) the objects are postcured in an adequate light curing unit in a protective gas atmosphere.

  • The dental objects generated out of the generative resin GR-20 MJF can be coated and repaired as usual.

  • Impurity due to operation mistakes cannot be excluded. With respect to the low viscosity of the resin it is possible to filtrate the GR-20 MJF. It is recommended to filtrate and stir up the resin on a regular base (fig 3).

  • To avoid bubbles let GR-20 MJF rest for 1 hour before usage.


  • To avoid detrimental effects on material quality do not expose the liquid material to irradiation under any circumstances.

  • Deviations from the described manufacturing process may lead to different mechanical and optical properties of the GR-20 MJF material.

  • Ensure personal protective gear during processing.

  • Caution: Polymerised resins are chemically resistant -avoid stains on clothing.

  • Avoid any contact with skin and eyes. In case of accidental contact, rinse with adequate running water, consulting a doctor if necessary.

  • The lot number and the best before date are indicated on each GR-20 MJF packaging. In case of claims please always indicate the lot number of the product. Do not use the product after expiry of the best before date.
