How to use

  • GR-18.1 bottles should be well shaked before use (fig 1).

  • Make sure that GR-18.1 material is temperature adjusted up to 23 °C to 30 °C.

  • Carefully pour GR-18.1 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-18.1 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-18.1 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-18.1
    can be repaired with GR-18.1 resin.

  • Impurity due to operation mistakes cannot be excluded. With respect to the low viscosity of the resin it is possible to filtrate the GR-18.1 . It is recommended to filtrate and stir up the resin on a regular base (fig 3).

  • To avoid bubbles let GR-18.1 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-18.1 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 expiration date are indicated on each bottle of GR-18.1 . 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.
