Webinar: Going Big in Metal 3D Printing: Insights from Experts


This webinar will help attendees understand how large parts are built using metal 3D printing, how to design for the process and the additional considerations required for post print processing and quality requirements. Whether the attendee is new to additive manufacturing or evaluating metal 3D printing technology for their production project, this presentation will help identify when the technology provides the most value and what to consider when manufacturing large additive metal parts.

Attendees will learn:

  • What industries and applications can benefit most from metal 3D printing
  • How to design large metal parts for the metal 3D printing process
  • What to consider when evaluating metal 3D printing for a production project


  • Joe Cretella, Application Engineer, Protolabs
  • René de Cauze de Nazelle, Senior Product Manager, GE Additive


Joe Cretella is an application engineer with seven years of experience in rapid prototyping and additive manufacturing. His focus is on stereolithography, selective laser sintering, MultiJet Fusion, and direct metal laser sintering technologies and provides guidance to engineers on designing for manufacturability. Joe regularly consults with product development professionals from a range of industries including medical, consumer products, aerospace and automotive. He graduated from East Carolina University with a degree in Industrial and Systems Engineering and is currently working for Protolabs, a rapid manufacturing company specializing in custom prototypes and low-volume production parts.

With more than three years of experience in several engineering roles in additive manufacturing, René du Cauze de Nazelle is currently the senior product manager for GE Additive’s X Line direct metal laser melting (DMLM) machine. Before working in additive manufacturing, René worked in a variety of engineering roles at GE’s Global Research Center in Munich, supporting various industries, including oil & gas and aviation. René holds a master’s degree in Space & Aeronautical Engineering from Imperial College London.
