1. Product description

pro3dure´s generative resin GR-19 OA is a resin for for 3D-printing systems
(SLA, DLP) with irradiation sources ( ≤ 405 nm) for orthodontic appliances.
The formulation of GR-19 OA is optimized for the requirements of a robust
production guaranteeing constant high quality. The GR-19 OA is successful­ly tested for biocompatibility, certainly meets all mechanical and application
demands. The material can be used for build processes with layer thicknesses
from 25 up to 100 μm. It is recommended to use the pro3dure medical curing
device CD-1 or CD-2 for post curing.

2. Processing

GR-19 OA bottles should be well shaked before use (fig 1).
Make sure that GR-19 OA material is temperature adjusted up to 23 °C to 30 °C.
Carefully pour GR-19 OA 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-19 OA 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-19 OA 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
(e.g. pro3dure´s CD-1 or CD-2 for a period of 3-4 min.) in a protective
gas atmosphere.

The dental objects generated out of the generative resin GR-19 OA
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-19 OA. It is
recommended to filtrate and stir up the resin on a regular base (fig 3).
To avoid bubbles let GR-19 OA rest for 1 hour before usage.

Contains: Alkoxilated bisphenole-A-dimethacrylate, initiators, dyes
and stabilisers.

3. 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-19 OA 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-19 OA

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.

Safety advice

pro3dure medical GmbH is not liable for any damages caused by improper
