Some rapid prototyping processes may need secondary processes like curing, painting, or polishing to get the preferred results.  Also, it would be best to consider the required time and resources for the post-processing steps.

Rapid Prototyping 

Rapid prototyping is the process of quickly building a 3D object to visually, and functionally, evaluate a design.  There are several popular methods to choose from to rapidly prototype an object including vacuum casting, CNC machining and 3D printing to name a few. There are two categories within rapid prototyping: 

Low-fidelity prototypes: this is when the prototype has noticeable differentiations to the proposed final product.  

High-fidelity prototypes: this is when the prototype matches the proposed final product. 

Applications: 

Rapid prototyping processes are largely used by product designers and engineers. This is because it enables them to physically view how their product will appear or work in the early stages of design.  

Having a physical model is also beneficial for clients who are working with designers, as it allows them to comprehend each aspect of the product in context. As a result, clients are generally able to provide designers with more accurate feedback because they can see and touch it. This gives room for alterations and improvements to be made in the early stages.
