See the info about the new T66-BT2 machines on the bottom of this page The Perfactory machine: This is a brand new technology just released in summer of 2003 based on photo polymerization. A DLP chip ( Digital Light Processing) developed by Texas Instruments is used to project the bitmap layers to the surface. The CAD model is sliced up and every slice is reflected on the upper glass surface where the light sensitive resin will cure into a solid plastic.  After a few seconds of curing it will be peeled off and the upper table holding the piece will move up 0.025 mm in Z direction then comes the next layer ... and this is how the piece will be built. We can achieve a minimum of 0.015mm layer thickness with this machine. However most of the jewelry is being built at 0.020mm layers. It means that 1mm thickness will be built by 50 layers piled up.... this is the one third of a human hair's diameter. We think that's more than enough to create fine jewelry.
Visit Envisiontec's website for more details: http://www.envisiontec.com/ If you have a CAD file that you want to build you can E-mail it to us. All 3 of our Perfactory machines has the ERM pixel shifting technology to give us more platform size and finer pixel size on the x and Y axis. Now we can print at true 0.014 mm volumetric pixel (voxel) resolution.

T66 machines: www.solid-scape.com Quick Questions related to the info in this page: Q:Is the Envisiontec and the Invision HR are the same machine? A:No, not at all. This Perfactory machine is made by the Envisiontec Company in Germany. The Invision HR machine is made by the 3D Systems company in California. Q:How does your Perfactory machines resolution compares with the Invision HR? A:The Invision machine's resolution is given by the company in DPI ( dots per inch) 656 X 656 X 800 dpi x,y,z resolution. One inch is = 25.4 mm So 25.4 / 656 = 0.0387 mm size pixel or minimum achievable resolution. The Perfactory ERM resolution is 2560 X 2048 in X,Y and the platform is 51 X 41 mm in size. So this gives us : 51mm / 2548 = 0.0199 mm resolution which is Twice as fine as the Invision Hr is capable of printing. The Z dimension on the Perfactory is chosen on the software : 0.015 , 0.020, 0.025, etc There is also another resolution issue that deserves attention: The jet printing machine's parts have a "splatter" effect which also decreases resolution accuracy. Conclusion: If your part need to be fine, have it printed with a Perfactory ERM! We happened to have one, so we can help you. Q:Are the printed parts directly castable from Perfactory? A:YES we can print in a Green castable resin ( PIC100 ). Q:Can I get a silver prototype from you from My file? A:YES you can, however there is no need for the silver prototype master anymore, since you will get the perfectly clean and accurate resin and this is what we use to make a non shrink silicone mold for production. ( the old fashion way was to have a silver model and to make a regular rubber mold, where you had to calculate shrinkage to the final part) Q:Are the printed parts directly castable from the T66 ? A:YES you can cast it just like any other injected wax with the normal process. Q:How much do you charge to print my files with the new T66 ? A:This process will be charged by the hour. We will slice your file with the T66 software and it will tell us precisely how long will take to print your parts. |
