No offense but somehow you got your figures wrong. The Revpoint Miraco price, straight from the manufacturer website, starts from $1,299.00, while the EinScan-SE v2 price begins from $1199 (again, straight from manufacturer’s website). Both scanners are priced way higher than the “within $800” limit you stated, and we’re discussing here of basic/standard versions, as for the premium versions pricing goes way higher.
I just bought the Creality Scan Feret Pro. It will produce STL files that can be read by Bambu Studio or most any slicer. The reason I bought it was that it can scan black items as well as color. No need to spray dark items with white powder. It’s handheld and has “shake” compensation. When used with a newer Android phone, it’s completely portable. It also comes with a Wifi module that can connect directly to a PC with Creality Scan software. Or, if close enough, scan to a PC with an included USB 3.0+ cable.
The surfaces it has problems with is clear, reflective (mirror, chrome, etc.) and small or thin edges.
I think that’s subject to opinion. I have multiple units from resin to filament and the Bambu lab x1c is far superior to the other in print speed and quality. They are all great in their own right but Bambu labs you can add an sd card which can serve the same purpose, but convenience is you will have built in monitoring systems and ability to send prints from anywhere to it. If you add the AMS or multiple AMS systems the ability to print up to 16 colors is awesome, minus the color change Poop as they call it. all subjective and based on opinions and convenience and what and how you plan to use them in your lesson planning
