Developers and users of industrial remote laser beam welding applications are often faced with different challenges under the conditions of series production. First, those applications are preferably conducted without any localized gas shielding, and therefore, specific interactions between the laser radiation and the welding fumes are very likely to occur, causing an impairment of the process stability, the reliability and the weld seam quality. Second, welding fume residuals are […]

Prima Power was an exhibitor at Laser Institute of America’s LME 2018, held March 28-29 at the Renaissance Schaumburg Convention Center, Schaumburg, IL. After show hours on March 28, Prima Power hosted an Open House at its showroom in nearby Arlington Heights, IL. A large group of visitors, composed of laser industry experts, suppliers, and prospective customers were able to get a close-up view of the Prima Power Laser Next 3D Laser.
Thanks to a deep and unique experience of over 35 years in this field and to a continuous dialogue with customers and partners operating in the […]
Dr. Kay Ball Releases Revision of Lasers – The Perioperative Challenge Through Laser Institute of America
ORLANDO, FL, March 21, 2018 — Published through the Laser Institute of America (LIA), renowned author Dr. Kay Ball has revised her book, Lasers – The Perioperative Challenge, to provide updated laser technology information to healthcare professionals. This is the fourth edition; the first was published in 1990, and Dr. Ball notes that much has evolved in the laser world since then.
“Dr. Ball’s book is an excellent read for medical personnel who are new to the use of lasers in medicine and wish to get a comprehensive understanding of lasers used in surgery and other areas outside of the OR. The […]
ORLANDO, FL (March 19, 2018) – The Laser Institute of America is excited to announce that the 2018 Lasers for Manufacturing Event® (LME®) will be held at the Schaumburg Convention Center in Schaumburg, Illinois March 28-29. This year will be the first time the event will be co-located with the Laser Additive Manufacturing (LAM®) Conference, which takes place March 27-28.
LME offers an opportunity for anyone interested in using lasers in manufacturing to learn more about commercial applications and interact with companies that offer laser manufacturing solutions.
The event will feature about 60 exhibitors, including Amplitude, Ekspla, Light Conversion, Lumentum, […]
Design Guidelines for Laser Metal Deposition of Lightweight Structures
By Ake Ewald and Josef Schlattmann
Weight critical applications, like parts in the aerospace industry, are driven by lightweight design. Titanium alloys have great potential in lightweight design of structural parts due to their excellent specific mechanical properties. Today, structural parts are manufactured in conventional milling processes. Titanium parts are characterized by poor milling behaviour as well as high material waste rates up to 95 % . The Laser Metal Deposition (LMD) is a layer-wise manufacturing process for the production of three-dimensional complex parts .
LMD builds parts based on a nozzle-fed powder, […]

The laser market is booming! While the U.S. economy in general is on a tear with the stock markets at record highs, the laser industry in particular is showing better financial numbers than the overall economy. The total laser market was up approximately 20% in 2017 relative to 2016, making it one of the best years in the history of the laser industry, and it appears that 2018 could show just as much growth.
The laser market is growing due to manufacturers discovering the use of lasers to improve their processes. Don’t be left behind […]

Laser Additive Manufacturing (LAM) is one of the most exciting potential growth areas for the laser industry. The market has been watched for a few years and every year there are gains in the revenue generated by this market segment, but so far the revenue curve has not started rising dramatically. This can be viewed as both good news and bad news. The “bad” news is that the market has not exploded…yet! According to Alan Nogee from Strategies Unlimited, the industry can be broken down as follows:
• Stereolithography – Reasonable growth but the industry depends […]
ORLANDO, FL (February 16, 2018) – The Laser Institute of America is pleased to announce that the 2018 Laser Additive Manufacturing (LAM®) conference will be held at the Schaumburg Convention Center in Schaumburg, IL, March 27–28. For the first time in its 10-year history, the conference will be co-located with the Lasers in Manufacturing Event® (LME®). LAM attendees will be granted free access to the LME exhibit, which takes place March 28–29.
The LAM conference is an excellent networking and educational opportunity for anyone interested in working in the additive manufacturing industry or discovering laser additive manufacturing solutions for their […]
Combination of Short and Ultrashort Pulse Laser Processing for Productive Large Scale Structuring of 3D Plastic Mould Steel
By: Andreas Brenner, Fraunhofer-Institute for Laser Technology and Fabian Kurzidim, Volkswagen AG
Increasing demand for surface functionality
Surface functionality is an increasing and crucial factor for the success and acceptance of a product. Through structured surfaces products can gain additional functions. In the automotive industry for example microstructures enable friction reduction in combustion engines or optimize lighting efficiency in LED lights. A glance into a vehicle’s interior is enough to see that detailed structures convey the feeling of exclusivity. For a long time, leather was the dominant look. Now the preference is for fine, more technical structures.
Able to offer virtually unlimited precision, lasers […]
The U.S. Department of Energy (DOE) is hosting an American Inventions Made Onshore (AIM Onshore) competition with the hope of encouraging more domestic manufacturing of energy technologies.
Business incubators, accelerators and universities selected to participate in the competition will partake in the Build4Scale manufacturing training program to educate energy technology entrepreneurs about manufacturing practices and to connect them to U.S.-based manufacturers.
Four organizations will be chosen to lead the training and will be awarded $150,000 each. After a year of training, the DOE will evaluate the organizations’ performance based on the revenue they generated from investors and the number of partnerships […]
