This process was born mainly to create prototypes before making the expensive molds used for plastic injection equipments for production in mass.
An injection mold can cost thousands of dollars. Companies spent millions because sometimes they had to repeat the mold 2, 3 and up to 4 times to obtain what they wished, a simple design error could cost a lot of time and money.
With this technology we can correct errors, touch, modify and see how it will be our final product whichever times we want before making the final mold, having a significant saving in time and money.
Actually there are many technologies of 3D printing. Actually we use FDM ( fused deposition material ).
FDM is also used to produce parts in series & end-user parts. It depends on the final cost of a mold and the number of parts needed. The resistance to the impact can varies from one material to another. In many cases ABS works fine.
