Rapid production: Survey says e-manufacturing is ready for the mass market
Mass production in the Western world is on the brink of a silent revolution and e-manufacturing is an important part of that change. These are some of the conclusions of a survey conducted by EOS at recent trade shows in Germany.
EOS , the world-leading manufacturer of laser-sintering systems, interviewed industry experts at the K 2007 show in Duesseldorf and Euromold 2007 in Frankfurt. Respondents were asked to focus on the following core questions:
EOS says the answers confirm that industrial production is facing a paradigm shift: e-manufacturing with laser-sintering is a key technology that will strongly compete with conventional technologies, such as casting, in the future.
E-manufacturing delivers end products, functional parts and tools directly from CAD data—that’s where the‘e’ in e-manufacturing derives from. A laser heats and melts powdered plastics or metals layer by layer, until the build is complete and a final product can be taken out of the system. Whether it is jewelry, clothes, lamps, chairs, or functional parts for industry that are being manufactured, e-manufacturing enables the creation of products with highly complex and filigreed structures and forms that are unthinkable geometries for conventional series production.
Is e-manufacturing ready for the mass market?
Seventy percent of the interviewees answered “yes” to this question, while 33 percent believe that individualized production with laser-sintering is already market-ready, while 37 percent predict the establishment of the technology in the market within the next three years. The rest anticipate establishment of e-manufacturing within five years, with only
Phrase of the future: Mass customization
What actually drives e-manufacturing? The key answer is the trend towards individualized series production—also called mass customization. Both industry and end consumers increasingly request individually manufactured products, creating a potential demand for mass customization of those products. And this is exactly where e-manufacturing comes into play:
Twenty-eight percent of those interviewed said the trend towards individualized series production is the most important factor for the success of the technology.
Nearly a quarter of the interviewees saw greater cost savings compared to conventional technologies. Twenty-two percent judged that e-manufacturing will overtake traditional technologies due to “shorter product life cycles.”
Significantly fewer interviewees counted factors such as “automated, unmanned production” (15 percent) and “decentralized production” (11 percent) as primary success factors.
Challenges, barriers, obstacles
As with every innovative technology, e-manufacturing with laser-sintering is not completely immune to competition from other methods; conventional technologies still offer some advantages, according to survey participants.
Twenty-nine percent of the interviewees called the limited choice of materials the greatest barrier to implementation of e-manufacturing technology.
Approximately a quarter of the respondents judged the “lack of know-how in the industry” as a hindrance.
Another quarter believes a lack of awareness about the technology is the main obstacle.
The rest cited “lack of innovative power across companies” (12 percent) and “outdated production structures” (11 percent).
The majority of the interviewees thus felt that the difficulty is not so much the emerging technology itself, but rather a lack of knowledge and openness in the industry.
Will current production methods die?
Finally the interviewees were asked for their predictions about production methods 20 years in the future.
A clear majority (63 percent) forecast the establishment of individualized mass production in the Western world.
Twenty one percent believes end customers will have their own mini-factories and produce their own products with Rapid Manufacturing.
Dr. Hans J. Langer, founder and CEO of EOS, feels that the results of the survey confirm his evaluation of the market: “We have been observing the trend towards mass customization for a few years already,” he says. “The number of consumer goods applications is increasing significantly, and manufacturers are seeing clear advantages with e-manufacturing, especially when it comes to freedom of design.
“EOS is currently working intensively on the development of new materials,” he adds. “We are fully aware that material choice is going to be a significant driver for our business in the future.”
