    Shrinkage problem of Vero material

    Hi all,

    I had a 3D printing company print a 3mm thick ring with around 430mm o.d. using the Vero material. Over the past two weeks the ambient temperature in our lab changed quite a lot (down by over 10 deg C) and I found the ring to have shrunken by 2-3mm in terms of arc length. Is this something I should expect for Vero? Is there any material that has a lower shrinkage rate?

    Thanks

    It's the same as Vero White but in black colour using Objet 260 Connex printer. You may refer to the link below for more information:

    ah right so it's a polyjet.
    Is there any kind of post print curing stage you've missed out ?

    Ah - you didn't print it.

    Can i suggest you ask the people who printed it. Their knowlege of this stuff is probably greater than anyone round here :-)
    That does sound like a lot of shrinkage to me. Just wondering if it's been drying out, rather than reacting to a small thermal change - hence the thought that it wasn't correctly post processed.
    But I am just guessing.
