Post-Processing of AM and 3D-Printed Parts

The special report provides a broad range of methods and techniques for finishing parts made by additive manufacturing (AM), also referred to as 3D printing.

The report includes six tables and 81 images and illustrations. It was created by a team of experts at Wohlers Associates—the same group that produced Wohlers Report 2022, the undisputed, industry-leading report on AM for 27 years.

ISBN 978-0-9913332-8-8

Organizations involved with AM have vast amounts of post-processing knowledge and experience, yet little systematic documentation is available. This has led to countless companies “reinventing the wheel” and spending time and money unnecessarily to complete jobs. This report has detailed information on methods of post-processing for most types of AM parts. The 43-page publication is available in digital form.

The special report, titled Post-Processing of AM and 3D-Printed Parts, provides a broad range of methods and techniques for finishing parts made by additive manufacturing (AM), also referred to as 3D printing. Most parts made by AM require some form of post-processing.
