he field of laser applications continues its seemingly inexorable growth. As people learn what lasers can do, an increasing range of applications is explored. In
addition, with power available in an increasing range of wavelengths and pulse widths, more and more applications become economically viable. At LIA we held our fiſth Lasers for

event gathered these individuals – over half of whom attending for the first time – who are involved in manufacturing complex, lightweight, parts from metal and various other structural materials. From 3D printing and cladding to rapid manufacturing and sintering, presentations covered a plethora of revolutionary additive manufacturing (AM) methods that continued the workshop’s tradition of building enthusiasm in the industry. Te event, which was held at the Embassy
T
Suites in Orlando, FL from 2-3 March, featured numerous speakers from key companies involved in the industry. Presenters hailed from firms including Keystone Synergistic Enterprises, Fabrisonic, Rolls Royce and General Electric, as well as universities from around the world that are making important advances in additive manufacturing. LAM general chair Paul Denney of Lincoln
Electric led the 2016 workshop, along with co-chairs Ingomar Kelbassa from Siemens and

Show time for laser tech By Peter Baker, Executive Director, Laser Institute of America
Manufacturing Event (LME) on 26-27 April, where we surveyed the range of applications and presented them to new users. Ten, on 16-20 October in San Diego, we will hold our 35th ICALEO. Here, pioneering work on the technology will be presented, giving some insight into new technologies and applications. San Diego in October? Sounds good to me.

LAM 2016: an in-depth look at additive manufacturing’s challenges and successes By Betsy Marone
Jim Sears from GE Global Research Center. Together, they designed the programme to look not only at how people are using AM in industry today, but also at the situations in which lasers offer the best solution when compared to other technologies. ‘New this year was a session dedicated to
technologies (electron beam, arc welding and ultrasonic) that compete against lasers for additive manufacturing,’ said Denney. ‘We also had presentations from end users that addressed when and why they select a technology for AM. Tese two sessions were designed to make those involved with laser additive understand the competition, and to help people selecting additive processing to choose lasers if it makes sense for their needs.’ Te first day of the workshop began with a
project [AM material sales] to reach $1 billion by 2025, materials issues still remain a concern

session on alternative technologies, which featured a keynote presentation by Professor Sudarsanam Suresh Babu from the University of Tennessee at Knoxville. His presentation focused
on recent advances in metal additive manufacturing, as well as the role in-situ process monitoring, computational monitoring and advanced characterisation play in the field. Professor Babu’s discussion of AM’s benefits, compared to traditional manufacturing methods, gave way to an overview of the additive manufacturing process – from geometrical conformity and topography optimisation to size-specific properties and beyond. Raymond Walker from Keystone
Synergistic Enterprises – a company that has been involved in AM for more than 20 years and is currently focused on cost-reduction and the use of additive manufacturing to make larger scale products – discussed the large-scale robotic pulsed-arc the company is developing. Te robotic arc prototype Walker presented to the
crowd has several benefits that make it a promising alternative technology. Not only is it stable and uniform, but it has in-process sensors for process verification and can calculate the melt pool for monitoring, record events away
