Well, the part is fundamentally not designed for FDM printing, because it has no natural flat area.
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. It all starts with making a virtual design of the object you want to create. This virtual design is made in a CAD (Computer Aided Design) file using a 3D modeling program (for the creation of a totally new object) or with the use of a 3D scanner (to copy an existing object). A 3D scanner makes a 3D digital copy of an object. A few months ago, I got the services from "Iannone 3D" who provides best FDM 3D Printing Services (ABS, Nylon, PC, Ultem, etc.) in the New Jersey area.
