Obstacles to the Adoption of Additive Manufacturing

Renishaw was a user of additive manufacturing before it became an OEM supplying additive manufacturing technology—specifically, laser melting systems for producing metal parts. For a metrology company to diversify into additive manufacturing machinery in this way indicates the long-term promise the company sees for this method of manufacturing.

In the short term, however, there are challenges. Renishaw’s Robin Weston, marketing manager for additive manufacturing products, recently detailed the challenges in a presentation given at the company’s Miskin site, where laser melting machines are produced.

He says the list below comprises the major obstacles that are slowing additive manufacturing’s adoption. In other words, the adoption of additive manufacturing is poised to accelerate, as each of these challenges is confronted and overcome:

 

Adoption of AM—the challenges today

1. Component redesigns are crucial to the business case for an AM system, because the full value is realized only by parts designed to take advantage of AM.

2. Not enough people are trained yet in designing for AM.

3. Software needs more development. Tools for design for AM are not yet common in CAD packages.

4. AM can bring significant change to distribution and business models based on conventional manufacturing. This could be an unwelcome disruption.

5. AM technologies remain too expensive and too slow. The machine marketplace is still immature.

6. International standards and practices for performance measurement and monitoring must be developed. This will require collaboration and partnerships between competitors, including both users and manufacturers of AM systems.
