Description
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 high elongation values of the GR-11 make the impression for the dentist and patient comfortable and safe.
COMPATIBLE WITH DLP/LCD/SLA 3D PRINTERS

How to use
-
GR-11 bottles should be well shaked before use (fig 1).
-
Make sure that GR-11 material is temperature adjusted up to 23 °C to 30 °C.
-
Carefully pour GR-11 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-11 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-11 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-11can 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-11. It is recommended to filtrate and stir up the resin on a regular base (fig 3).
-
To avoid bubbles let GR-11 rest for 1 hour before usage.
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-11 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.
