Advantages of manufacturing cases on a 3D printer
There is no need to make a mold, as in the case of casting. This implies:
We have no restrictions on the size of the future cases. We are not tied to the size of the working area of the TPA.
Without the need to manufacture the mold there is no need to wait for its manufacture.
No mold - no extra spending on complex and long, and as a result, expensive process of its manufacture.
Complexity of shape
Split molds inherent limitation on the complexity of the form. No mold is required for 3D printing.
