Additive Manufacturing Group (AMG)

AMG

INTRODUCTION

Additive Manufacturing Group (AMG) focuses on developing additive manufacturing technologies to produce metal, polymer, and ceramic products with complex and precise geometries. The group harnesses the digital flexibility of these transformative technologies to deliver performance enhancements, fabrication simplifications, and supply chain resilience. This is achieved through the group’s deep end-to-end expertise in AM technologies ranging from design, simulation, feedstock development, AM processes, post-processing, quality assurance to applications. 

AMG strives to advance additive manufacturing technologies towards ubiquitous adoption as an integrated, smart, resilient, and sustainable manufacturing path. AMG welcomes industry partners and academia to collaborate with SIMTech in cutting-edge research and to develop new solutions through projects and joint labs. AMG also looks forward to opportunities to transfer technologies and conduct training for the manufacturing industry.
