I just can't undestand why my model isn't printable

    Dear Friends,
    I'm going to print my first 3d model but at the moment I can't because my file is not valid.
    I already checked it and:
    - it is manifold
    - it is closed
    - it observes dimensional restraints
    - normals are well positioned

    So what could it be the problem ??? :mad: :mad: :mad:

    It is a heart-shaped earring that I obtained by piping some non-filleted curves (its design is really geometric) in Rhinoceros...could it be the problem?

    Thanks in advance

    One common problem is that some programs export files with the wrong dimensions.. Too large/Too small for the printers.
    Can you share the file?

    Not enough information - what is the actual error message you receive from shapeways,
    and what file format is it that you try to upload ? (Also have you checked the file you exported
    with meshlab or netfabb, or are you relying on what you see in rhino ? )

    Sure. What kind of format do you like ?

    Cannot speak for stonysmith obviously, but STL would probably not be a bad choice. (Unless you intend a multicolor
    object, in which case I would opt for VRML2). (And if your problem is just that absolutely nothing happened after you
    uploaded your file, be aware that there have been at least intermittent server problems since yesterday.)

    Ok, the problem was due to a file type error. Shapeways did not accept my X3D, X3DB, X3DV and DAE files but it gets it if I save in STL.
    Someone that could explain me why?

    In the meanwhile, thanks to everybody that helped me !!
    Really gratefull !!! :) :) :)

    Did you try to upload a texture with the X3D variants (or was your model in rhino texured in any way that might make rhino try to include
    a texture file path on export, even if you had not intended it to) ? One of the basic differences between STL and said other formats is that
    STL contains only mesh coordinates - no colors, no textures or anything fancy.
    Then there is always the possibility of a bug in the exporting program, X3D is a rather eloquent, XML-based format, so a missing field or bracket can make importing fail. Impossible to tell without seeing the file that failed - if you are curious, you could try viewing your X3D with view3dscene or some other vrml/x3d viewer.

    No texture or something similar, I'm just print some prototypes in blank, white plastic.
