Go to my shop
Wow 6 years since this thread was started and I find I am suffering from exactly the same problems described here !

I recently had 9 models rejected, mostly in steel.

These models awalls exceed the stated requirements as admitted by Shapeways support.
They are also similar to many other models I have been printing over the last year or so.

Obviously Shapeways has decided for reasons you explain in your post here
that I am pushing the boundaries or what is reliable to print.

I am ... disappointed and angry that I have been allowed to spend thousands of dollars
developing models that are probably not printable enough to sell in the shop.
Really ... its disgusting that design guidelines are exceeded, the automated test is passed, test prints are done successfully, no one says there is a problem - and then suddenly most models are being rejected in the main target material.

Not only that, to make it MUCH WORSE ...
despite repeated requests for indications as to how much more support for weak area is required
I am getting no assistance on this at all.
As far as I can see this means I must spend more money doing various amounts of thickening of the supports
and discover for myself by spending more money on ordering test prints - exactly what is and isnt going to be acceptable.
And do this for every model !
Makes me want to puke.

Support's only suggestion is to make all the wires 3mm that are currently 1.2mm and according to specs could be as thin as .1mm.
On a 35mm model this is totally ridiculous. AND if this is applied to all my models it will make about 40 of hem unprintable in steel.

If anyone on Shapeways staff actually reads this and would like to help -
I have followed your guidelines and been lead down your garden path.
I think that you owe it to me to at least work with me to make these models printable.
Im sure that is possible, and you have the knowledge and skills to do it.

Sacred Geometry is the study of the fundamental forms of space and time to reveal the secrets of the physical and spiritual worlds. It is a key to good Science, a secret of great Art, and a much needed common ground for the worlds multifarious religions.
