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.
