Hey all!

I have a few small changes to the White Strong & Flexible material. We've been working on learning how to print bigger parts more effectively after welcome The Beast (our EOS P760 Printer) to the Shapeways family.

These changes should only affect less than 1% of the WSF parts.

There are a few proposed changes:
1) Maximum bounding box: 66x35x55 cm (3 cm off of each dimension). We've found that parts extending to the edge of the printer tends to get warped, so to make sure the parts turn out dandy, we are shaving 3 cm off of the larger pieces.

2) Wall thickness for bigger parts: we will no longer be distinguishing between outer and inner walls. I think this just confused people and didn't really help that much anyway. The walls for big parts (parts with any dimension exceeding 11.7cm or 4.6in) should be thicker as the part gets bigger. There's a handy calculator to help you figure out what the minimum wall is for your model.

3) WSF Minimum Bounding Box: there are a few really really small parts that we've cost in the dusting sieves. We are currently working on a minimum bounding box for WSF parts. It will be something like 2.5x.2.5x2.5mm or something where the bounding box dimensions add up to 7.5mm.

We will have more info on the bounding box, and hope to kick these changes live starting next Monday.

Thanks,
Nancy
