Good question. There are several 3D scanners in that price range, but I'm curious as to the difference between photogrammetry with a phone, something like the $800 SOL 3D, and the $10k+ handheld options.
The ~$1k 3D scanners out there advertise an accuracy of something like "up to 0.1mm," which puts them in the ballpark of the resolution a basic Prusa's likely to be able to reproduce, but I'm really unclear on how true that is in practice.
- errantspark 6y agoThere's likely some actual Nyquist-Shannon ish corollary that will tell you how much higher your scanning res has to be than your printing res, but 2x is probably a safe bet. Not to mention "accuracy" tells an imprecise story. Does it mean that the best case scenario every point is at most 0.1mm from where it should be? That doesn't mean the same thing as "accurately resolves features larger than 0.1mm³".
