I'm at my whits end. What Shapeways is seeing wrong with my model has no place in what I designed. Where do they see this problem and why is it there? The jpeg came attached with the shapeways message. The octa3.scad is my code that I used to generate the STL I've uploaded to shapeways. The STL is big, 57Mega. The rendering of the 5th order fractal takes a long time. I'm writing to the list not really to ask for help, because having anyone wait for this to render overnight only to seek the needle in the haystack is too much to ask. But I am writing merely to express frustration with openscad/shapeways combination. I for one don't know how to go about finding what went wrong. Am I missing something? -------- Forwarded Message -------- Subject: Help us resolve issues with models in order 882138 Date: Thu, 29 Jan 2015 07:51:30 +0000 (UTC) From: Shapeways Team <service@shapeways.com> Reply-To: Shapeways Team <service@shapeways.com> To: adriang0@cox.net Help us resolve issues with models in order 882138 Shapeways <http://www.shapeways.com?etId=29208328&utm_source=automated-contact&utm_medium=email&utm_campaign=order-rejected-so&utm_content=0&ca=email&ct=order-rejected-so&cr=0> Hello adriang0, After taking a closer look, we are unable to manufacture one of the products in order 882138 <http://www.shapeways.com/checkout/receipt?orderId=882138etId=29208328&utm_source=automated-contact&utm_medium=email&utm_campaign=order-rejected-so&utm_content=2&ca=email&ct=order-rejected-so&cr=2> (placed on 01/29/2015). * You will not be charged for this product.

Our “Strong and Flexible” materials are printed with a process known as selective laser sintering. The product is a composition of hundreds of microscopic layers melted together by a laser and suspended in an unmelted fine powder. We remove the solid models from the loose powder by hand and use sandblasting and compressed air equipment to achieve a fully cleaned surface. When the product is encased in loose powder it is similar to as if it were encased in a snow bank. The loose powder can at times be tough or difficult to remove. To avoid breaking your product in this stage, it is important that models are sturdy enough to be lifted and support the weight of excess powder while it is being cleaned. In your model, the areas pictured are at risk of breaking as the structure is too thin to withstand the weight of the loose powder around them, or the pressure needed to clean your product. The design may be more successful if the broken areas are thickened. We encourage you to iterate on your design to ensure a quality print. Please consider: 1. Thickening the shown thin areas of your model, and giving it another once over for other potentially thin areas. 2. Using our Wall Thickness checker! When you upload a model you will see a 3D view of your model with potentially thin areas shown in yellow. 3. Ordering this model in a material with smaller minimum requirements 4. Reordering this model in the current material with "Print It Anyway" selected, in which case we will print this model trying our best to avoid damaging it. If breakages occur, we’ll ship your product “as is” and encourage you to iterate on your design for a more robust product. If you intend to order or sell this model in a dyed or polished material either now or in the future, please also consider that these areas must be strong enough to withstand our polishing procedure as well. This involves several hours in an industrial sized rotary vibrator under the weight of thousands of small ceramic pellets. Find additional information in the attached image.
