Manufacturing prototypes with 3D printing
What is rapid prototyping?,
Rapid prototyping is the process of quickly making a non-final version of a product to test design ideas and get data that will help improve future iterations. The term is closely tied to additive manufacturing (3D printing) technology as it was originally used to describe the process of making a 3D model using computer aided design (CAD) data which would then be used to 3D print an object, or part on an object, for testing purposes.

Why 3D print your rapid prototypes?
As previously mentioned, 3D printing technology originally inspired the creation of rapid prototyping as a concept. While other manufacturing techniques such as injection molding and CNC machining can be used for rapid prototyping, 3D printing remains one of the most suited. The goal of any rapid prototyping exercise is to make a quick version of a product that can be used to perform experiments and test assumptions. That means you need to be able to make custom one-off designs and then modify those designs in successive iterations. You need to be able to produce those iterations as quickly as possible, and the more freedom you have in designing your prototypes, the better. And of course, to justify your experiments financially, all the above requirements need come at an affordable price. Let’s take a look at how well 3D printing matches those criteria:

Speed
When it comes to on-off or small-batch manufacturing, 3D printing is king. Lead times stay low because new custom molds don’t need to be made and you don’t need to wait for your order to be shipped. For medium-to-small objects, it’s possible to create a new 3D design during the day, let it print overnight, and retrieve your completed object from the printer the next morning.

Flexibility
The ability to make changes and iterate on a custom design is another area where 3D printing excels. To 3D print an object, you first need to create a digital 3D model of it. 3D models can be changed, replicated, and shared in any way you wish. If a series of experiments is unsuccessful; you can simply load up a previous version and try something else. 3D printing also gives you a lot of flexibility when it comes to the physical properties of your prototypes. Just some of the properties that can be varied depending on the material used are mechanical strength, rigidity, temperature resistance, chemical resistance, dimensional accuracy, and color..
