Process-Monitoring Software for AM

Wednesday, July 18, 2018

Renishaw introduces its InfiniAM Spectral, a new additive-manufacturing (AM) process-monitoring software part of a developing family of products that help users capture, evaluate, present and store process data from Renishaw laser powder-bed fusion technologies.

The software, to formally debut at IMTS 2018 this September in Chicago, IL, helps AM users gain a greater understanding of their processes and overcome the difficulties with AM in critical applications, process stability and part quality, according to company officials. The new software offers two measurement functions in the sensor modules. The first module, LaserView, uses a photosensitive diode to measure the intensity of the laser energy. The second module, MeltView, captures emissions from the melt pool in the near-infrared and infrared spectral ranges.

The modules stream data across a conventional computer network on a layer-by-layer basis, allowing manufacturers to analyze process-monitoring data in real-time. As the build progresses, the data are rendered live in 3D for viewing in InfiniAM Spectral. Engineers can compare the data from each sensor to identify any deviations, which may indicate the presence of anomalies that could lead to defects.

“The amount of process data generated during an AM build is immense, which means it can be difficult to make practical use of it without the correct interpretation tools,” explains Robin Weston, marketing manager at Renishaw’s Additive Manufacturing Products division. “InfiniAM Spectral will be beneficial to manufacturers because it allows them to easily translate the data. That will lead to more consistent AM outcomes.”

Metal Powder AM to Surpass $1.1 Billion by 2024

Wednesday, July 18, 2018

According to a new study by Global Market Insights, the market demand for aluminum alloys additively manufactured with metal powders should exceed 27 percent by 2024, to a total of $1.1 billion. More than 20 percent of aerospace engineering companies are using additive manufacturing (AM) technology to make tooling components. 

The industry is constantly putting effort into minimizing aircraft weight by using lightweight metals such as stainless steel, titanium, aluminum and copper. Stainless steel, aluminum, cobalt, nickel and titanium powders are the prominent raw materials used in metal powder AM.

Oerlikon and Lufthansa Technik Join to Accelerate AM

Tuesday, July 17, 2018

Oerlikon, a Swiss technology and engineering group, and Lufthansa Technik, a Hamburg, Germany-based provider of maintenance, repair and overhaul (MRO) services for civil aircraft, engines and components, recently signed a Memorandum of Understanding to establish robust and repeatable processes for additive manufacturing (AM) in the aircraft MRO industry.

The processes will be shared with relevant industry bodies to support defining standards for the qualification and approval of aircraft components.

World's First Family to Live in a 3D-Printed Home

Monday, July 16, 2018
A family in Nantes, France, has become the world's first family to move in to a 3D-printed home.

Their four-bedroom property is a prototype for bigger 3D-printed housing projects aimed at making housebuilding cheaper and faster.

"It's a big honor to be a part of this project,” says Nordine Ramdani. Nordine, Nouria, and their three children are the family who were chosen to live in the home. 

The four-bedroom house was made collaboratively by the city council, a housing association, and the University of Nantes. Frank Trichet, the council's tech and innovation lead, says the purpose of the project is to test the waters before trying to employ such technology for mainstream commercial housing projects and larger community buildings.

Pitt Receives Grant to Study 3D Printing

Monday, July 16, 2018

The University of Pittsburgh’s Swanson School of Engineering has been awarded $1 million to study and advance the design and manufacture of 3D-printed nuclear components. The award is part of the United States Department of Energy (DOE) Office of Nuclear Energy’s Nuclear Energy Enabling Technologies (NEET) program. 

The research will involve the development of dissolvable supports, as well as greater topology optimization (the way in which parts are interrelated or arranged) and improved microstructure design to fabricate nuclear components with minimal distortion and greater structural integrity at lower costs. 

The research will be directed by Albert To, associate professor of Mechanical Engineering and Materials Science (MEMS) at the Swanson School. Co-investigators include Wei Xiong, assistant professor of MEMS at Pitt, and Owen Hildreth, assistant professor of mechanical engineering at the Colorado School of Mines. Corporate collaborators in Pittsburgh include Curtiss-Wright, a mechanical contracting corporation and Jason Goldsmith at Kennametal Inc., a supplier of tooling and industrial materials.
