Dear all,
I have to mention, that the first material will change into a orange, translucent methacrylate with following preliminary material properties (the homepage will be updated before the Euromold in December 2002):
Biegefestigkeit / Bending strength: 65 MPa
Biegemodul / Bending module: 1840 MPa
Biegedehnung / Elongation at break: 9 %
Viskosität / Viscosity (not polymerized): 400 cps (mPas)
Materialeigenschaften nach / Material properties afer postcuring:
DIN EN ISO 178
20 min nachbelichtet unter / postcured under UV+Halogen Licht/light
Kind regards

Tim, al lot of information on their web site,
http://www.envisiontec.de/21hdesca.htm . They are using a methacrylate
right now, I've pasted in some of the info from their web site:
Mechanical Properties (preliminary) - Resinsystem Perfactory®
Group: Acrylat
Color: red-brown (not transparent)
Viskosity: 400 mPas (20°C); (not polymerized)
Three-point Bending test - polymerized Resin
Parameter:
Bending modul: Secant modul from 0,05 - 0,4 mm elongation
Test speed: 1 mm/min
Test part geomety: 2´2´25 mm
Support width: 15 mm
Light source: High-pressure mercury vapor lamp
Results:
Perfactory®
Light oven
(5 min post exposure) (20 min exposure)
Bending strength: 90 - 100 MPa 70 - 80 MPa
Bending Module: 1800 - 2000 MPa 1500 - 1600 MPa
Elongation at break: 6 - 9 % 10 - 13 %
Shore Hardness DIN 53505
Shore D: 80 - 85 75- 80
