Another day, another rejected customer order, and this time for the excuse that makes the least sense for scale models: Printability issue: Detail Too Fine This model has detail that is too fine to be visible after printing. ... Please consider: 1. Extruding the detail further from the model's primary surface 2. Removing any detail that is unnecessary. 3. Ordering the model in a material with finer resolution 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 create it to your specification. I design scale model airplanes for sale on Shapeways. Though most of my models are in the 1:144 to 1:288 scale, I do have some that range as high as 1:72 and as small as 1:600. I also offer models in three materials: Versatile, Professional, and Modeling plastics, and each of those materials have different parameters. Imagine I model a cover plate with six nut-heads visible¹, emulating the same feature on the real-life plane. Those nut heads do not protrude far enough from the surface to be considered "wires" -- instead they are classified as surface details. When I resize a model to smaller and smaller sizes, I realize I may need to thicken walls or increase wire diameters to meet material minimums, but I do not try to remove detail. Going back to those nut heads, I would have to realize that they work at 1:72 and 1:144, but at 1:285 they slipped below the minimum size limit and need to be removed. Oh, wait, perhaps at 1:144 they meet the limit for one material but not for another, so I have to have one model for one material and a different model for another. Easy enough for six nut heads, but there might be hundreds of details on the plane that need to be examined for each material and each scale and removed or retained depending on the scale and material. That would be quite impractical. Instead, if I leave the nut heads there all the way down to 1:600, no one is ever going to complain if they are not visible in a print at such a small scale. The printer software doesn't care; the customer doesn't care; I don't care. For every model, in every material and at every scale, the actual output of the printer is only an approximate copy of the original digital model, and everyone knows that. I don't know if there are cases where "Detail Too Fine" is something you really need to enforce for someone somewhere. But for the entire class of scale models, I doubt there is a designer or customer anywhere that would say, "thank god you didn't try to print that because I couldn't see the nut heads at that resolution". Instead, it pops up now and then as a lame excuse not to print a model. My recommendation to Shapeways is to either eliminate of that criteria or let designers mark their designs with "please don't enforce 'Detail Too Fine'". ¹ I use this example because it's easy to visualize.
