Dear Johnn,

Z axis is 230mm!!. Arranging the rings in a correct fashion on the platform will ensures the claims.
Please note that the geometry of the ring does play an important role in ascertaining the no. of rings that can be placed on the platform.

  Dear Anuj,

  I have questions on your following claims :

  1. What is the exposure times you can set up on Envisiontec machine ?

  2. How you can fit 12-14 rings in the XY envelope of 41 x 33 mm of 32 micron resolution ? & how you can fit 25-28 rings in XY envelope of 77 x 61 mm in 60 micron resolution ?

  Look forward to your reply soon. I will appreciate reply from Envisiontec, Germany explaining these claims.

    Dear John,

    Perfactory speed is as follows -

    1) With 0.025 mm layer thickness, build speed is 8-10mm / hr (depending on the exposure time you set your machine at), thus for 33mm height of ring, it would take 3.5 - 4 hrs. In 32 micron platform built, about 12-14 rings can be made and in 60 micron built platform, about 25-28 rings can be made at a time. (also depends on the geometry of the ring)

    2) with 0.050 mm layer thickness, built speed is approx. 15mm / hr and can take from 2.5-2.75hrs to built the 33mm ring. . No. of rings made on individual platform would be same as above.

    Thanking you.

        Dear List,

        Can some users of Perfactory system for Jewellery applications can update me on the following data -

        1. Build speed in mm/hr with 0.025 mm layer thickness, with 32 & 60 microm pixel size. How many rings possible with height of 33 mm, per platform built in these resolutions.

        2, Same data as above but now with 0,050 layers

        Look for feedbacks.
