2025 Emerging Tech Webinar Series
February 5, 2025
1:00pm-2:00pm ET
Laser-powder directed energy deposition (LP-DED) reduces lead times and offers potential benefits for the gear industry, but more research is needed on the performance of DED-manufactured and repaired gears for widespread adoption.
The Gear Research Institute (at Penn State University) and EtxeTar have studied Dievar, a tool steel material, for gear manufacturing by LP-DED. We have analyzed Dievar’s processability, hardness, toughness and bending fatigue performance. We applied the gained knowledge to repair a gear tooth of a CNC machine broken during the assembly process.
Igor Ortiz (EtxeTar) is going to introduce the industrial case application and some of the studied properties of Dievar processes by LP-DED.
Dr. Aaron Isaacson is going to present the novel method developed at GRI for efficiently study the bending fatigue behavior of teeth manufactured with new processes and alloys. He is also going to present the results obtained with Dievar.
Presenters
Igor Ortiz
R&D Project Manager
EtxeTar
Igor Ortiz is a R&D Project Manager for special projects at EtxeTar, with over 15 years of expertise in product development, computer aided engineering (CAE), computer aided manufacturing (CAM) and production facilities. He holds an MSc in Industrial Engineering from Ecole CESI (France), an MBA from the University of Barcelona. He has completed an executive program in Mergers & Acquisitions from ESADE business school. Sponsored by his company, currently he is pursuing an international PhD at the Polytechnic University of Madrid and research stays at Penn State University. Igor focuses his research on the fatigue analysis of laser-powder DED manufactured gear teeth.
Igor is leading multiple programs at Penn State University’s Gear Research Institute (GRI), Center for Innovative Materials Processing through Direct Digital Deposition (CIMP-3D) and Millennium Science Complex. His experience includes automotive, turbomachinery, oil and gas and aerospace industries. Currently, he leads an advanced robot laser cell program for repairing and coating high-value parts, focusing on the automation of laser processes (laser-powder DED, hardening, peening) and developing workflows and processes for laser technology.
