Details

The details don't list a minimum wall-thickness for anything other than Cream Robust. Is there a set thickness we must meet for each material, or is this arbitrary? If there is, can you add that to the specifications?

Well spotted, we haven't added that information to the page.

I will do so.

The wall thickness does depend on the material.

As a general rule the easiest thing to do is to keep all walls thicker than 2mm.

If you go below this you run the risk of your model being to delicate to print, clean or ship. There is also an increased chance of production errors if you use lower wall thicknesses.

Of course Cream Robust can have walls of 1.4mm and White, Strong & Flexible can have 1mm walls. Definitely do not go below this!

There is a tutorial on the subject here:

Hi,

Along with the minimum wall thickness, would it be possible, please, to add to the material option page the (now famous) "void" thickness, that is the minimum clearance for two moving objects not to be fused, depending on the material?
I lot of people seems to have done tests on that for you, so making the result easily available would avoid making again those kind of mistakes...
Thanks!


So many things to design, so little time...
