Design For Manufacturing: Importance And Key Principles


– Do you know what the toughest part of the manufacturing process is?

– It is to launch a product with the best design.

No matter how good an idea is, it is only great if the manufacture can turn them into reality. This is where Design For Manufacturing (DFM) comes into play.

Unfortunately, some designers considered the manufacturing process minor. They only realize it’s important when they find errors in the real product.

No matter how big or small the product is, design and manufacturing go hand in hand. Thus, neglecting its importance means you are welcoming hefty losses and inferior products.

Today, we are here to discuss the importance of DFM and its key principles.

Why Is Design For Manufacturing Important?

The reason why DFM is important is less about its benefits and more about finding problems with the products. DFM allows the organization to pinpoint the areas where the products can go wrong.

The main aim of DFM is to find:

  • Inefficient Process: The process of creating a product is equally important to the product itself. This is because, without an effective process, you cannot create an excellent product. DFM helps the creators develop a blueprint that produces only high-quality products.
  • Fatal Design Flaws: Some of the fatal design flaws do not surface until the creator goes for multiple products at a time. A single product made with all the focus by an expert will always be good, but multiple products made with a process can have flaws. DFM ensures that those flaws are taken care of.

Design For Manufacturing is becoming an important industry as we move forward with industrialization. So, if you want to have a bright career, become a certified SOLIDWORKS professional in Singapore.

Key Principles Of DFM

It is vital that you understand the principles working behind the DFM. These principles follow the common concept and help the organization to connect the manufacturing issue and design decisions.

If the manufacturing process can match the pace with the design, it can help to make the manufacturing process more efficient. In fact, you will get the most out of the production.

Below are the key principles on which DFM works.

1. Manufacturing Process Choice

The production process plays an important role in determining the total cost structure of the product. Hence, which production process you choose to use is a detrimental principle to consider.

2. Design Choice For Manufacturing Reality

You must know that bad design choices will negatively affect the production line. For instance, if you are making any unnecessary changes to a particular manufacturing process, it will disrupt the whole manufacturing process.

Hence, it is important that you have a robust design for manufacturing and must equip designers with the right information to understand the relationship between design choices and production concerns.

3. Effective Component Selection

Yes, smart component selection is important. Without the right component, you might not be able to reach an effective manufacturing process.

In addition, the right design for manufacturing allows you to compare the off-the-shelf component with the custom parts. This comparison gives you an idea of which part is more efficient than the other.

4. Tolerance

Design for manufacturing tools should help the organization with more precise optimization. That means the tool needs to be specific with its approach to fulfill the functional requirements and cost targets.

5. Tooling

An advanced and adequate design for the manufacturing process should start with estimating the total project cost.

Now, this cost includes everything that is needed to complete the project. In addition, you might as well include the tools needed for different designs.


Design For Manufacturing is important if you want to get the best out of the production process. This article has talked about its importance and the key principles that help you understand what DFM is all about.
