Application of Three-dimensional Printing (1) Rapid Prototyping
The earliest use of 3D printing was to use digital design objects as prototypes before producing new prototypes.
The advantages are evident in the following processes:
When design exists digitally in computers
After evaluation, an entity prototype that can be processed and manipulated is created according to the design.
Compare the printed prototype with the components of the existing system to ensure a match.
Creating an appreciable and touchable evaluation object for peaple can speed up the new design. Printed versions of 3D can be copied and compared much faster than individual instances of each design - which saves a lot of time and efforts and cost.
Normally, prototypes do not require the material strength of the final object design, so plastic or resin designs can be used to test objects before investing in the cost and materials required for metal replication.
Jewellers and other designers can test their designs with wax or biodegradable plastics, and then make final models from gold, silver or other valuable materials after customers approve their suitability and functionality.
3D printing is more widely used in aerospace and medical fields. Three-dimensional printing engines and three-dimensional printing of human organs are becoming reality.
