Penn State’s CIMP-3D recently demonstrated its capabilities for large format multi-laser powder bed fusion by fabricating three large aluminum components representative of fittings on industrial-scale piping systems. Working alongside 3D Systems, the entire production process was executed from start-to-finish, including: design-for-AM, fabrication, post-processing, and inspection.
For this demonstration, two 90-degree elbows and one globe valve body were manufactured. The parts were designed in SolidWorks and then exported to 3DXpert, where they were oriented to reduce supports and other fabrication risks. The parts were then additively manufactured in DMP Factory 500, which employ three lasers working simultaneously across the build plate to manufacture parts quickly and accurately within a build volume of 50 x 50 x 50 cm3 . The machine is vacuum sealed for a controlled print environment, ensuring high quality material. Once the parts were printed, excess powder was removed and recycled. Electrical discharge machining (EDM) was used to remove the parts from the build plate. Once removed from the build plate, the supports were manually removed, and post build inspection was conducted using ARL Penn State’s high power digital radiography. A video that covers this process can be found here:
This demonstration underscores the commitment at CIMP-3D to further advance its already world-class capabilities within metal based additive manufacturing to support US industry and the Department of Defense. The research institute is well equipped to undertake projects in large format multi-laser powder bed fusion. Its dedicated team of researchers bring a wealth of experience and expertise, allowing continuous improvements and innovations.
