Course Overview

Additive manufacturing (AM) and 3D printing (3DP) technologies have become widespread in all segments of research, development and manufacturing. It is essential that research, development and engineering professionals are aware of and familiar with the tools and techniques that are available to them to execute their tasks in the current competitive environment. The University of Akron, and its affiliated organizations, are in a position to educate and demonstrate already established and emerging technologies in a comprehensive curriculum of lectures and hands-on laboratory experiences.

As part of this 2 day course, a wide range of AM and 3DP content will be covered including:

  • History of 3D printing technology
  • Current market
  • Introduction to 3D printing concepts
  • Focus on methods
  • Focus on materials
  • 3D CAD modeling
  • Printer operation
  • Maintenance of printer platforms
  • Advances in printer capabilities
  • Alternative print methods
  • Part enhancement by secondary finishing
  • Economics of 3D printing
  • Pace of innovation and emerging technologies

Interactive live demonstrations include:

  • Definition and 3D CAD design of a complex part using Solidworks®
  • FDM and Polyjet® part manufacture
  • Substrate removal methods

Instructor Biography:

JOESUMERAK-2Joseph E. Sumerak received BSE (1973) and MSE (2001) degrees in Polymer Science from the Case Western Reserve University Department of Macromolecular Science. Sumerak has enjoyed a forty year career in composite materials design and manufacturing and has founded and operated several successful business ventures. Rapid prototyping methods were employed frequently in the execution of tooling and process development tasks in this field. In 2011 Sumerak started 4D Parts Direct, a 3D printing service provider, to expand upon this interest with a broad customer and market focus.
