America Makes Announces Awardees of Directed Project Opportunity on Advancing Additive Manufacturing Post-Processing Techniques
Goal is to Improve Process Control for Qualifying Complex Parts and Reduce Costs
Youngstown, Ohio — December 18, 2018. America Makes is proud to announce the awardees of a Directed Project Opportunity on advancing additive manufacturing (AM) post-processing techniques (AAPT), funded by the Air Force Research Laboratory (AFRL), Materials and Manufacturing Directorate, Manufacturing and Industrial Base Technology Division. Driven by the National Center for Defense Manufacturing and Machining (NCDMM), America Makes and AFRL awarded $1.6M to fund two awards with at least $800K in matching funds from the awarded project teams for total funding worth roughly $2.4M.
The focus of the AAPT Directed Project is of particular interest to AFRL. In order to expand the use of Selective Laser Melting (SLM) for critical parts, a better understanding of the available techniques is needed to achieve qualified parts and certified processes. The current lack of a consensus of best practices for material handling and post-processing leads to high variability and massive qualification challenges, invariably leading to higher costs to adopt and employ AM technologies. Through the AAPT Directed Project, AFRL specifically seeks to address two main issues. First, quantify the mechanical performance debit of using as built SLM surfaces to fabricate high-temperature nickel super alloy canonical features, such as thin walls and narrow flow channels. Second, quantify the effectiveness of Hot Isostatic Pressing (HIP) when producing high-temperature nickel super alloy canonical features, such as thin walls and narrow flow channels.
Subject to the finalization of all contractual details and requirements, the selected America Makes AAPT Directed Project Opportunity Awardees are:
Awardee #1: Arizona State University
Led by Arizona State University, in conjunction with Quintus Technologies; Phoenix Heat Treating, Inc.; and Phoenix Analysis & Design Technologies, Inc., this project team seeks to gain a better understanding of how mechanical properties, such as stiffness, strength and fatigue life for as-built structures (without machining), change as a function of size in metal AM. Additionally, the project team seeks to explore and pursue the fundamental reasons for how these findings change with respect to post-processing steps, such as HIP. In doing so, the project team anticipates being able to identify the relationships among process, specimen size, and post-processing to enable improved certification of AM processes and materials.
Awardee #2: ASTM International Additive Manufacturing Center of Excellence (AM CoE)
Led by the ASTM AM CoE, a collaborative, which includes ASTM International, Auburn University, EWI, the National Aeronautics and Space Administration (NASA), Wichita State University – National Institute for Aviation Research (NIAR), in conjunction with Quintus Technologies, Carpenter Technologies Corporation, Aerojet Rocketdyne, Rolls Royce Corporation, Honeywell Aerospace, GE Aviation, and Raytheon, the project team seeks to determine the mechanical performance debit of using as-built AM components, understand how this changes with application of HIP, test the values by burst testing thin wall components with narrow flow channels, and publish standards around these results in order to close industry known gaps.
“America Makes and AFRL are pleased to announce Arizona State University and ASTM International AM CoE as the AAPT Directed Project Opportunity awardees,” said Rob Gorham, America Makes Executive Director. “These project teams have outlined interesting approaches to better understanding mechanical and material properties during heat treatments. As a result, we anticipate the projects will yield important gains in process control, certified processes, and the qualification of materials and parts, which will all be instrumental in reducing post-processing costs—one of the biggest barriers to the wider adoption of AM technologies. On behalf of all of us at America Makes and AFRL, we extend our congratulations to Arizona State University and the ASTM International AM CoE and their respective teams.”
The anticipated start date of the projects is January 2019.
