What is Technology Readiness Level (TRL)? Understanding Its Importance in Innovation

Definition

Technology Readiness Level (TRL) is a systematic metric used to assess the maturity of a particular technology. Developed by NASA, the TRL scale ranges from 1 to 9, with 1 indicating basic principles observed and reported, and 9 representing technology that has been proven through successful mission operations. This scale helps organizations understand the development stage of a technology, from initial concept to full deployment.

Explain Technology Readiness Level (TRL) like I’m 5

Imagine you have an idea for a new toy. At the beginning, you just think about it (that’s level 1). Then you draw it, make a small model, test it, and keep improving it. Finally, you make a bunch of them and sell them in stores (that’s level 9). The TRL is like a report card that shows how close your toy is to being ready for everyone to use.

Why does this matter?

TRL is crucial in additive manufacturing because it provides a clear framework for evaluating the development and readiness of new 3D printing technologies and materials. This helps companies and researchers understand how close a technology is to being commercially viable and ensures that investments are made wisely. For instance, knowing the TRL of a new photopolymer resin can help manufacturers decide whether it’s ready for production or still needs more testing.

Real Talk

While the TRL scale is a useful tool for gauging technology maturity, it’s not without its limitations. It can sometimes oversimplify the complexities involved in technology development. Just because a technology reaches TRL 9 doesn’t mean it’s free from issues or ready for all applications. Additionally, the scale doesn’t account for market readiness or regulatory hurdles, which can be significant barriers to commercial success. So, while TRL is a helpful guide, it’s not the whole story.
