What is a key advantage of additive manufacturing in various industries?

Limited design flexibility

The key advantage of additive manufacturing is to limited design flexibility because Additive manufacturing technology enables OEMs to produce fewer components within a single produce, reducing the inventory significantly. 3D printing allows you to manufacture products without tooling and to consolidate assemblies into single parts.

Additive manufacturing has proven to be a powerful technology, revolutionizing production processes and business models across numerous industries. As the advantages of additive manufacturing have become more tangible, its applications have skyrocketed over the last few years. While 3D printing won't completely replace traditional manufacturing in the future, the technology's true strength comes into play when it is integrated with those conventional methods. After all, a simple error or delay on a production line can lead to big losses in both time and money. Integrating innovative technologies with additional benefits could be a worthy solution for any production line. This is all a part of responding to manufacturing industry change. According to Jabil's latest 3D Printing Trends survey of over 300 decision-makers, additive manufacturing has positively impacted every stage of the product lifecycle. Most importantly, participants report that prototyping and design have been the most positively impacted by 3D printing applications, followed by production tooling and production.
