Description
pro3dure´s GR-10 guide is a CERTIFIED biocompatible 3D printing resin, which has been developed for the production of surgical guides and splints. La in combination with exceptional clarity and highest UV-stability allows you to insert the drill sleeves effortlessly and offers you optimal control during surgery. GR-10 occlusal splints fulfil ll the highest demands on aesthetics and define the standard for 3D printed splints in terms of breaking stability.
pro3dure´s generative resin GR-10 guide is a resin for the generative production of dental objects based on image projection systems. The formulation
of GR-10 guide is optimized for the requirements of a robust production guaranteeing constant high quality. The GR-10 guide is successfully tested and certified 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.
COMPATIBLE WITH DLP/LCD/SLA 3D PRINTERS

How to use
-
GR-10 guide bottles should be well shaked before use (fig 1).
-
Make sure that GR-10 guide material is temperature adjusted up to 23 °C to 30 °C.
-
Carefully pour GR-10 guide 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-10 guide 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-10 guide 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-10 guide 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-10 guide.
-
It is recommended to filtrate and stir up the resin on a regular base (fig 3). To avoid bubbles let GR-10 guide 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-10 guide 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-10 guide
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.
