I'm guessing that the wall thickness was too small. With the flange inset on the bottom, the thickness would have been less than 3 mm.



I'm planning a redesign as two parts. The first is the valve handle with a very small pilot hole in the bottom. The second is the pipe section with a hole all the way through. Can this be printed?

Welcome to Shapeways!

I'm guessing the model pictured is one of the stainless steel variations(?) How does the model file volume (can be checked with NetFabb) compare to the uploaded model volume on your Shapeways model page?

I'm thinking although the center appears hollow in your model image, sometimes when different parts (shells) of a model share common planes, Shapeways automatic checking software merges the parts differently to how you might expect and either removes parts altogether or fill in areas.

With your redesign its worth checking the wall thicknesses with NetFabb. If it's stainless you're designing for, check the Design Rules and Advanced Design Rules

Thanks Paul! Yes its a bronze variant of the stainless printing. I downloaded NetFabb and checked as you instructed but am not sure where to get the volume from the upload page. I only find exterior "cube" dimensions of the model which I believe will only give maximum volume. Regardless, I redesigned the part as two pieces. We'll see what happens next.

Thanks Treadshot A1, it was water tight but I had to do a lot of editing to make it so. Its my first model with sketch-up for 3d printing so I still have much to learn. Is there an easy way to automatically eliminate the interior faces before printing or is it simply a matter of cleaning up the drawing as you go? Is Sketch-up the right tool for building models for 3D printing?]]> Mach 2011-10-13T11:42:59-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=36578&th=6657#msg_36578
Still, i'm upgrading to other programs soon, can't wait. Wouldn't say i hate Sketchup, but there's a reason why many laugh at it: there's far, far better.

And there's no way to easily eliminate interior faces. You just have to be very careful when modeling. It's all about learning the program. I've spent 2 and a half years on it now, and only a few months ago can i say i really managed to get the hang of it. So, yeah, enjoy the next year or two of intense struggling. j/k

Here's an example of what is practically the limits of sketchup, at least in my experience: http://www.shapeways.com/forum/index.php?t=msg&th=5586&a mp;start=0&]]> TreadshotA1 2011-10-13T11:58:44-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=36579&th=6657#msg_36579
Dizingof uses Sketchup and some of the items he churns out are astounding, so yes used in the right way, Sketchup is good for 3D printing.
