1, Price—CMM is more expensive than 3D laser scanner;
2, Accuracy—CMM can ensure higher accuracy than that of 3D laser scanner;
3, Portability—CMM hardly can move from one position to another, while portable 3D laser scanner is lightweight design and you can take it anywhere;
4, Working principle—CMM is touch-type measurement which is very old technology, for some soft material, it cannot measure at all; while portable 3D laser scanner is non-contact measurement, literally it can scan anything you like.
