    I'm having a problem and hope someone can help. The attached photo shows a 3D bust of my father-in-law. You can see what appears to be large gashes in the print. It is ABS, 230 degrees C, 110 degrees C heated bed. I use Simplify 3D software for slicing. The same thing happens when I try bronze fill PVA on a different model bust.

    I'd open the part up in netfabb and take a look.

    Run it through all of the repair tools in Simplify as well.

    If it were splitting horizontally (along layers) I'd say it was just ABS being ABS w/o a heated chamber. But assuming it actually prints that way from the start then it is likely a model error.

    P.S. This all is assuming that other models print that high without problems, otherwise it might simply be a mechanical binding of some sort.

    I run all of the models through Netfabb before printing. I even thickened the out layers to see if that helped, it didn't.

    Is it printing that way or is it splitting after printing?

    So, just to be clear, that picture is exactly how it printed.
    It didn't print correctly and then have the layers separate?

    If so then likely a model problem.
    You may be able to affect it by re-orienting the model print starting position, but I would expect one of the repair tools (in Netfab or Simplify) to at least complain if not repair.

    I believe it happened during the print. I printed it over night. I did bronze fill PVA with a different model but the same results.

    I have not had any issues with Bronzefill wanting to separate so if it happened with that as well then it almost has to be a model issue.
    It makes a big difference because if it printed correctly and then separated when cooling it is simply a filament issue (one that you get a lot with ABS). If it printed with the split/gap there then the model is not slicing correctly.

    You might ping simplify3d support people and provide them the model. They fixed one for me that was just refusing to print without layer skew. It was a model problem, but they still managed to get it fixed well enough for me to print it. Besides, you bought it so support was included in the price :)

    well that's strange.
    110C is more than you need.

    both models slice fine for me.
    I mean, there's plenty of problems with your print but you mean particularly the missing parts.
    side of the face and top of the head. Certainly looks like a slicing problem.
    What slicer are you using... regardless, try a different one.

    it slices fine in my simplify.
    I'm not going to print it... but strange.

    Yes Ben, it seems to look fine here as well. I would be willing to send you $5.00 to cover the cost of printing just to see how the print comes out on another Robo. If it prints fine, then it's my machine, if it does not, then it's the slicing.

    cheers,
    John

    My Robo is cold I can test print it for you (no charge--you get blue PLA).
    Downloaded the bust from thingiverse, imported into Simplify and got the warning amount MM/inches.
    Had it auto-convert and it is still a really small model.

    How large is this supposed to be?

    I click on the model and scale it to about 125 to 155. Size doesn't matter as I am most interested in the quality of the model.

    Cheers,
    John

    Printing now, needs about 30 minutes max.
    (scaled it by 125)
