About

Mattias Ottosson is a researcher specializing in robotized laser manufacturing, additive manufacturing automation, and process control systems for metal deposition technologies. His work has centered on advancing Robotized Laser Metal-wire Deposition (RLMwD), a cutting-edge technique for fabricating fully dense metal structures directly from CAD designs using fiber laser welding and wire filler material in a layered manufacturing approach. Ottosson's most significant contribution lies in developing feedback-based control systems to improve process stability and automation in laser metal-wire deposition. His 2009 paper, "Increased Stability in Laser Metal Wire Deposition through Feedback from Optical Measurements," has garnered 137 citations, demonstrating considerable influence in the field. This work addressed a critical challenge in additive manufacturing — maintaining consistent, reliable deposition quality — by integrating optical measurement feedback into the process control loop. His earlier research laid the foundational framework for full automation of free-form metal fabrication, moving the technology from experimental concept toward practical industrial application. Through a progression of studies from 2007 to 2009, Ottosson systematically tackled the automation and control design challenges inherent in RLMwD, contributing meaningfully to the broader field of metal additive manufacturing and robotized fabrication systems.
