There is no other method compares to 3D printing rapid prototyping when it comes to getting prototypes fast and at a low cost . If you need a preliminary sample to test for form, fit or simply aesthetics, 3D printing rapid prototyping is the best option. The complex geometries enabled by the 3D printing process let you create intricate parts to accurately gauge manufacturability and other considerations before making the decision to move to more functional testing. https://e-make.co/slasls-3d-printing/
