I’m exploring 3D scanning for capturing real-world objects and converting them into printable models. I’m curious about which scanning methods work best for small to medium-sized parts, especially when fine details matter.
How accurate are entry-level scanners compared to professional setups, and what’s the usual workflow to clean up scans for rapid prototyping? Any tips on reducing noise, holes, or distortion in scanned models would be greatly appreciated.
Blue line laser scanning is best for high detail on small to medium size parts, that would be the Raptor scanner from Creality which is around $900 or € on sale. Depends on what you consider an entry level scanner and a prefessional setup, you can also pay tens of thousands for professional 3D scanners, but the entry level scanners that Creality sells, the Ferret and the Otter Lite, don’t support laser line scanning and especially the Ferret doesn’t capture very fine detail.
Most of the post processing you can do with the Creality Scan application, it supports smoothing, filling holes (but better try to scan things from several angles and merge it so that there are no bigger holes to fill) and you can clean it up in the point cloud. Cleaning the model up later is usually harder and more work intense.
