Hign effiience of get a sample--3D printed model
The 3D printed model can be generated using a computer aided design software package or a 3D scanner. The process of manually collecting the geometric data needed to make a 3D image is similar to the sculpture art. By 3D scanning, electronic data about the shape, appearance, and the like of a real object can be generated and analyzed. Based on the data obtained from the 3D scan, a three-dimensional computer model of the scanned object can be generated.
Regardless of which 3D modeling software is used, the resulting 3D model (usually .skp, .dae, .3ds, or other formats) needs to be converted to a format that can be read by printers such as .STL or .OBJ.
Now many our customer get the outer shape product via 3D print.
It will be fast way to get the thing the customer need. It will short the order time.
And it's cost is lower than make a formal one
More and more project will choose this way.
