In the CNC world, I think rugosity is a factor in how well parts wear. Highly polished low rugosity parts wear better because they tend to introduce less friction. High rugosity components are more prone to wear and tear because of the imperfections in their surface structure. As I understand it, this can often be a huge issue with involute gear teeth like those in the Roughcut. But I'm not sure microfractures are a major concern in the NIC 🤔

Unfortunately, the only controls on inexpensive 3D printers appear to be print bias and infill. However, there are some 3rd party smoothers that produce a gloss-like finish on 3D parts. I've played with some of these and they work pretty well. But the hardness and longevity of the finish is questionable. It looks absolutely awesome, but I don't have any hard data.

In any event, I want to see how Flat's gear turns out. He downplays the significance, but I think the success of failure will determine whether we 3D reprint, or continue salvaging gears from broken blasters.

No pressure Flat 😉
