I am totally new to scanners. Got a POP3 at Amazon at discounted price ( USD 479 ) intending to use it for reverse engineering. The first thing I did after receiving it yesterday is to check the long-distance accuracy. Two pieces of ply woods were clamped onto the table and seperated accurately by 570mm. The seperation was governed by 123 blocks and guage blocks. The error should be within 0.07 mm. Some features were put in the middle to help tracking. The scanning process went extremely well. Just one single pass from left to right and it was done. The accuracy of the model was checked in Fusion 360 and it turned out that the error was 0.32 mm。 Should be good enough for my hobby purpose.
