What Is Rapid Prototyping?

Rapid prototyping is a process that allows you to quickly create physical or digital versions of your product to test it out and get feedback from users. By creating a prototype, you can check for design flaws early on, which will help you save time and money in the long run.

Benefits of Rapid Prototyping

There are numerous benefits of rapid prototyping, such as: 

Quicker development cycles

Rapid prototypes can help reduce the amount of time it takes to develop a product. This can lead to shorter development times and faster time to market for products. Also in CNC milling prototype development, the software is used to generate the shapes and forms of the product being developed.

Improved usability testing

By creating prototypes, developers can gain valuable feedback from users sooner than if they were to wait until the product was completed. This feedback can help developers identify design flaws and usability issues, which can be addressed before the product is released. 

Increased creativity

Rapid prototyping allows for more creative solutions as it gives developers the opportunity to explore different ideas without committing to a single solution. 

People may hardly distinguish between rapid prototyping and additive manufacturing. Additive manufacturing (AM), or 3D printing, is a rapid manufacturing process that combines computer-aided design, material processing, and molding technology to produce solid objects out of special metal materials, non-metal materials, and medical biomaterials using extrusion, sintering, fusion, light curing, spraying, and other ways to stack layer by layer.

Four Facts About Rapid Prototyping And Additive Manufacturing

1. Rapid prototyping and additive manufacturing are not the same. Additive manufacturing is one of the rapid prototyping manufacturing methods. 

Additive manufacturing is based on digital model files through software and a numerical control system. Rapid prototyping or manufacturing covers lots of manufacturing methods, including CNC machining, vacuum casting, reaction injection molding, rapid tooling, etc.

2. Additive manufacturing excels in producing complex-structured parts.

In contrast to the traditional processing methods of removing, cutting, and assembling raw materials, it is a "bottom-up" method of manufacturing by accumulating materials from scratch. It makes it possible to manufacture complex structural parts that were not possible in the past due to the constraints of traditional rapid prototyping manufacturing methods.


3. Additive manufacturing avoids material waste.

As it prints components layer by layer, additive manufacturing never wastes raw materials like subtractive manufacturing such as CNC machining. It is a must for CNC machining to cut raw materials, resulting in a certain amount of waste.

4. One of the new trends in additive manufacturing is the combination of additive manufacturing with CNC machining within one machine.

Recent publications have described a metal 3-D printer integrated with a CNC machine. It uses multiple laser high-power lasers that melt metal directly onto the object, resulting in a fully-welded part. The machine can use wire, metal powder, or both simultaneously without changing the nozzle. It can print a range of metals, including stainless steel, Inconel, and titanium. The process is cost-effective and can manufacture big-sized complex 3D components, for example, the five-bladed naval propeller. It can also modify existing parts and even repair metal parts that have been cracked or damaged. 

In the past two decades, AM technology has been developing very rapidly. It will be applied more and more in rapid industrial manufacturing. 

How to Get Started With Rapid Prototyping

If you want to get started with rapid prototyping, there are several tools and techniques that you can use: 

Types of prototyping

There are several types of prototyping that developers can use to increase their productivity. Low-fidelity prototypes allow for quick and easy testing, while high-fidelity prototypes provide a more accurate representation of the final product. 

User testing

No matter which type of prototype is used, user testing should be an integral part of the process. User feedback is invaluable when it comes to creating a successful product, and rapid prototyping provides an efficient way to get such feedback quickly. 

Iterative design

Rapid prototyping encourages an iterative approach to design. This allows developers to continuously refine their ideas until they reach perfection. 


Additive manufacturing is just one method of rapid prototyping. Prototype creators usually offer the most appropriate manufacturing methods based on specific prototyping needs.
