How to use

Preparation:

• GR-17 temporary bottles should be well shaken before use (Fig.1).

• Make sure that GR-17 temporary temperature is within 23 °C to 30 °C. If possible, always store a bottle GR-17 temporary in your production unit in order to avoid temperature differences during refilling.

• Impurities due to operational mistakes cannot be excluded. With respect to the low viscosity of the resin it is possible to filtrate GR-17 temporary and stir it on a regular base (Fig.3). To avoid bubbles let GR-17 temporary rest for 1 hour before usage.

Manufacturing process:

1. Prepare data (CAD & build preparation).
2. Choose process parameters (build style, etc.).
3. Transfer prepared data to 3D printing device.
4. Prepare 3D printing – shake bottle.
5. Fill resin tank of 3D printing device (Fig.2). Bubbles can be removed with a clean spatula or by a recoater routine.
6. Build the parts.
7. Clean parts (with IPA ≥ 97 % or equivalent cleaning agent)
   approx. 10 min. in an ultrasonic bath or equivalent
   device – precleaning recommended.
8. Dry parts, until there are no residues of IPA or equivalent
   cleaning agent.
9. Post curing (2 x 5 min. / wall thickness > 2.5 mm: 2 x 10 min.):
   inert atmosphere recommended (use adequate light
   curing device).
10. Finish parts. The dental objects created with GR-17 temporary can be coated and repaired as usual.

Important

• 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-17 temporary material.

• Ensure personal protective gear during processing.

• Caution: Polymerized 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-17 temporary 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.
