The Terminology Challenge

Rapid prototyping has served well as an umbrella term for a long time. In recent years, the application of additive technology has expanded beyond prototyping. Many companies are using it for visualization—not as prototypes—and for custom products and series production. It becomes awkward, even misleading, to say that you’re using rapid prototyping (RP) for the direct manufacture of products. What’s more, it is confusing to those who are new to the technology and industry.

Rapid prototyping is an important application of additive fabrication technology, but it is only one of many applications. A growing number of people are using additive fabrication as an umbrella term to encompass stereolithography, laser sintering, fused deposition modeling, 3DP from Z Corp., PolyJet from Objet Geometries, and other additive processes. I’ve been using additive fabrication because it more accurately describes the process. I’m not thrilled about the eight syllables, but I like it better than the alternatives.

Whichever umbrella term one chooses to use over the next few years, I believe it will be temporary. Long term, I believe 3D printing will prevail as the generic term of choice. It’s simple, descriptive, and easy to say. What’s more, 70% of all additive systems sold last year were categorized as a 3D printer. In the future, more than nine out of 10 additive systems sold annually will be a 3D printer.

In the short term, 3D printer will continue to mean what it means today to most people close to the technology: A relatively inexpensive, easy-to-use, and office friendly additive process that fabricates concept models and prototype parts. In the meantime, additive fabrication works well as an umbrella term to describe the wide range of processes that fabricate objects layer by layer.

The Future of Additive Fabrication

One of the most asked questions related to additive fabrication technology revolves around its future. People across many industries frequently ask about the potential of additive machines and materials and their expanding breadth of applications. A growing number of users of the technology for rapid prototyping anticipate the day when they and others will use additive processes for custom parts and short run production. Already, dozens of organizations have tried it and many have experienced success, even though rapid manufacturing is in its very early phase of development. RM presents a wide range of opportunities and challenges.

 

The future of additive fabrication will be the topic of discussion at an upcoming international conference at EuroMold 2006 in Frankfurt, Germany. Carefully selected speakers from several industries, including aerospace, automotive, and medical, will present their views and opinions in the one-day event titled Future Industrial Applications of Additive Fabrication. Through examples of what’s been tried, coupled with years of experience and insight, the speakers will explain how and why the future of product design and manufacturing will be impacted by this very powerful technology.

 

If you are planning to attend EuroMold, plan to attend this Friday, December 1 conference. You can register on-site, but it’s better to do it in advance. Go to the EuroMold website to see the conference program and pre-register. Also, plan to stay for the annual party and reception that follows directly after the conference. Everyone in attendance will have the opportunity to win valuable gifts and prizes.

 

I hope to see you in Frankfurt in less than three weeks.
