additive manufacturing The classes aren’t for engineering students. “Our targets


are operators and engineers who want to build parts,” he said. “We’re aiming not only for a training program but also certifying people for specifi c applications.” UL also is involved with a 3D printing education project in


Singapore. In November, the company announced a partnership with Georgia Institute of Technology and Emory University for a two-year study of the effect of 3D printing on indoor air quality. UL sees additive manufacturing at a key point—and is moving to become a player by helping companies establish production processes and safety standards for 3D printing. In 2015, Krampitz said, fi rms were developing business cases for using 3D printing and were identifying the prod- ucts suitable for AM and which processes to use. This year, companies are “building up the details to sup- port [3D] production of the parts,” he said. “We’ve seen this wave of development of going to market in 2018, late 2017.” UL is helping companies develop their practices for using 3D printing.


“These industry standards are going to take time,” he said. Companies interested in using 3D printing are “not waiting for the standards. They’re now developing internal requirements.” Much of the 3D printing development to date has occurred in aerospace and medical. Aerospace heavily


uses expensive materials, such as titanium, that are diffi cult to machine and where much of the material is wasted when cutting it away. Additive manufacturing could be a way to produce new designs that are more effi cient to manufacture. Medical devices are small and often require elaborate shapes.


“The challenge is that [3D printing] development has been driven by one or two industries,” Krampitz said. UL sees another wave as more materials are certifi ed for 3D printing, including new metals and ceramics.


‘Neutral Party’


UL is trying to position itself as an entity that can help a client implement 3D printing while satisfying regulators, insur- ance companies and others that additive-produced parts meet (or exceed) the quality of traditionally produced components. “We’re a neutral party,” Krampitz said. “People know us


for rigorous testing and analysis.” UL’s 3D printing work covers safety, training and advisory services for part and facility conformance to regulations, industry standards and technical requirements plus equip- ment and material compliance to regulations. There are about 10 employees in UL’s additive manufacturing practice and is still hiring.


Additive manufacturing training takes place at a training facility managed by UL and the University of Louisville. 120 — Aerospace & Defense Manufacturing 2016
