The prostheses defined handmade are made entirely by hand, both in the sculpture phase (the creation of the base, which will affect the appearance and final consistency of the prosthesis), and in the assembly phase (handmade prostheses cannot be composed of a single piece for the level of realism they must satisfy), both in the painting phase (application of color, this phase gives the prosthesis the realism that the FTM seeks). The sculpture phase is fundamental for providing the prosthesis its shape, while the painting phase is fundamental for moving from a prosthesis with the appearance of a toy to a realistic prosthesis.

Handmade and handpainted prostheses are handcrafted, highly personalized products. In these cases, two perfectly identical prostheses cannot exist, because each one is made to measure for the customer who requested it.
