Key Takeaways:

  1. Prototyping in manufacturing involves creating a working model (or prototype) of a product before it goes into mass production.
  2. Common prototyping techniques include C.N.C. machining, 3D printing, and injection molding.
  3. The right manufacturing process for your prototype will depend on the accuracy requirements and materials involved.

There is a range of manufacturing processes used for prototyping, making it difficult to decide which one to use. In this blog post, New Product Consulting will take a closer look at the most popular types of prototyping manufacturing processes and see how they can be used to create prototypes for your business. We’ll also take a satirical look at some of the less popular methods and see how they could potentially be improved. So, without further ado, let’s take a look at some of the most popular types of manufacturing processes for prototyping!

What Is Prototyping In Manufacturing?

Prototyping in manufacturing involves developing a working model (or prototype) of a product before it is mass-produced. This allows businesses to test the product to see if it meets stakeholder requirements and make necessary changes before committing to full-scale production.

Types of Prototyping Processes

There are many different types of prototyping processes, each with its advantages and disadvantages. The most popular methods are listed below:

1. Basic Manufacturing

Basic manufacturing is the simplest and most common type of prototyping. It involves developing a prototype using the same methods used to mass-produce the product. This is generally done by hand or with basic machinery.

Advantages:

  • Simple and easy to do
  • Inexpensive
  • Can be done quickly

Disadvantages:

  • Limited to simple products
  • May not be accurate
  • Changes are difficult to make

2. Additive Manufacturing

Additive manufacturing, A.K.A. 3D printing, is a process in which a three-dimensional object is developed by adding layers of material one at a time. This is accomplished using a Computer-Aided Design (CAD) file or 3D scan.

Advantages:

  • Can be used to develop complex shapes
  • Inexpensive
  • Changes can be made easily

Disadvantages:

  • Slow process
  • Limited to small objects
  • Materials are not always durable

3. Subtractive Manufacturing

Subtractive manufacturing is the outright opposite of additive manufacturing. It involves removing material from a block of raw material to create a prototype. This can be done with machining, milling, or lathing.

Advantages:

  • Can be used to develop large objects
  • Accuracy

Disadvantages:

  • Slow process
  • Can be expensive
  • A lot of waste material is left behind

4. Molding and Casting

Molding and casting is a manufacturing process used to develop prototypes from metals, plastics, or other materials. A mold is created using a CAD file or 3D scan. Then, the prototype is created by pouring liquid material into the mold. After the prototype hardens, it is removed from the mold.

Advantages:

  • Can be used to create complex shapes
  • Inexpensive

Disadvantages:

  • Changes cannot be made easily
  • Materials are not always durable
  • Time-consuming

5. Rapid Prototyping

Rapid prototyping is a manufacturing process that is used to develop prototypes from 3D CAD files. The prototype is built by layering thin sheets of material, one on top of the other. This process can be utilized to develop prototypes from plastics, metals, or other materials.

Advantages:

  • Can be used to create complex shapes
  • Inexpensive
  • Quick turnaround time

Disadvantages:

  • Changes cannot be made easily
  • Materials are not always strong
  • Limited to small objects

Various Types of Product Prototypes

Now that we’ve gone over how to develop prototypes let’s talk about the different types of product prototypes.

1. Proof of Concept Prototype

A proof-of-concept prototype is a prototype that is created to test a certain concept or theory. This prototype is usually developed early in the product development process before making a more detailed prototype.

2. Functional Prototype

This is used to test a product’s functionality. This prototype is usually developed after a proof-of-concept prototype has been made. This prototype will be more detailed and closer to the final product.

3. Aesthetics Prototype

This is used to test a product’s appearance. This prototype is usually developed after a functional prototype has been made. This prototype will be close to the final product in terms of appearance.

4. User Interface Prototype

This is designed to test a product’s user interface. This prototype is usually developed after a functional prototype has been made. This prototype will be close to the final product’s user interface.

5. Manufacturing Prototype

A manufacturing prototype is designed to test a product’s manufacturing process. This prototype is usually created after a functional prototype has been made. This prototype will be close to the final product in the manufacturing process.

The Importance of Product Prototyping:

In a world of uncertainty, product prototyping has been a game changer for businesses. By developing prototypes, businesses have reduced the risk of investing in a product that will not be successful. Prototyping also allows businesses to test their products before they go to market. This allows them to ensure that their product is ready for mass production.

C.N.C. machining vs. 3D printing: Which is right for your prototype manufacturing process?

3D printing has become the go-to technology for prototyping. It is fast, efficient, and relatively inexpensive. However, there are some drawbacks to using 3D printing for prototyping. One of the biggest drawbacks is that 3D printed prototypes can be less accurate than C.N.C. machined prototypes.

C.N.C. machining is a more traditional manufacturing process that has been around for decades. Unlike 3D printing, C.N.C. machining develops prototypes from solid blocks of material. This gives C.N.C. machined prototypes a higher level of accuracy. Another advantage of C.N.C. machining is that it can be used to develop prototypes from a wider range of materials, including metals and plastics.

So, which technology is right for your prototype manufacturing process? It depends on your prototype’s accuracy requirements and the materials you need to use. If you need a very accurate prototype made from metal or plastic, C.N.C. machining is probably your best bet. If accuracy is not essential, but you need a prototype developed quickly and cheaply, 3D printing might be a better option.
