Choosing a Fabrication Method (Prototyping vs Mass Production)

As we build our knowledge database, we want to share with you all that we know — from design and engineering tips, to manufacturing hardware — , in our mission to #HelpMakersMake. Learn More.

As technologies evolve, we see an increasing number of different ways to fabricate our products. From CNC machining to 3D printing, sheet metal fabrication to injection molding, we are spoilt for choice when it comes to the methods available to us. With so many options, how do we choose which is the best method to use?

The ideal method often depends on what the part is going to be used for. Is it for prototyping or mass production? Prototyping often involves low volume production and requires a short turnaround time as you iterate quickly. Mass production on the other hand often looks at lowering cost per piece with a high quality finish. Knowing this, let us take a look at what are the common fabrication methods available to us and see where they can be applied.

3D printing is one of the fastest evolving technologies. Becoming popular in the 2000s, it became one of the best methods for prototyping. While 3D printing uses both plastics and metals, plastics are often preferred due to their lower cost. There are a wide range of plastics to choose from depending on the application. Additive manufacturing takes little to no time to set up, making it cost efficient when producing low quantities. More often than not, your part will be ready in a day or two. It is great…
