AW: Resolution/Minimum feature size A NEW technology

Dear all,

I have to excuse myself that our homepage is not up to date. We have had some changes at Envisiontec GmbH (former Envision Technologies GmbH) working now under the direction of a strategic private investor (instead of venture capital).

Actually we are preparing our System PERFACTORY (presented at the Euomold Dec. 2002 in Frankfurt) for delivery in March 2003.

There will be two systems available:

The system is based on photopolymerisation NOT using a laser but DLP-Technology. Running costs are roughly 1500 Euro/year.

PERFACTORY Standard 59.900,00 Euro (list price)
Resolution SXGA 1280 x 1024
Build envelope XYZ 200 x 160 x 230 mm down to 120 x 96 x 230 mm
Pixel Size 160 µm 93 µm
Layer Thickness 50 - 100 µm
Building Speed constant ca. 10 mm/h with 100 µm layers

PERFACTORY Mini 49.900,00 Euro (list price)
Resolution SXGA 1280 x 1024
Build envelope XYZ 90 x 72 x 230 mm down to 55 x 44 x 230 mm
Pixel Size 70 µm 43 µm
Layer Thickness 25 - 50 µm
Building Speed constant ca. 20 mm/h with 50 µm layers

Technical Data may change due to further optimization.

The acrylic resin (200 Euro/Liter) can be used for investment casting, if dental casting methods are used (burn out temp. at 700 - 800 °C).

Market entrance in Europe will be March 2003 and in USA probably June/July 2003.

Please contact me directly if further information is required.

Kind Regards

All good points Sheba. I too have visited this sight and wondered about the
machines capabilities, price and availability. I would be interested in any
info anyone else might have.

Although, since the material doesn't appear to be castable it doesn't
answer this particular guy's question.

I've seen this site mentioned before, and it does leave me with a lot
of questions. Is this machine available in the US? Do any service
bureaus have it? What did the list price turn out to be? How does it
handle undercutting? How are the process and the parts different from

There is only one tiny picture of a part made by the machine - not
really enough to tell what it can do.
