As additive manufacturing of metal parts continues to transform from prototyping to production, we’ve seen materials expand, systems improve, and automation advance. But, until recently, we haven’t seen an increased focus on post-processing, especially as it pertains to binder jet (BJ) technologies. But, with the recent resurgence of binder jet, due to its potential as a high-volume production method, understanding of the post-processing stage of the workflow is critical.

In this report, we look at the common post-processing steps for binder jet parts, what they can achieve, and the challenges observed. We will discuss the relative cost considerations to keep in mind as well as costs that often go unaccounted for in the workflow. We will also discuss many of the OEMs and service providers that are active in this space. And, often forgotten, we will discuss some of the critical considerations in the design stage that can greatly influence the post-processing stage in the overall workflow. We finish with a discussion on the future trends, to include end-to-end solutions and automation, data optimization, software solutions, and the current state of standards and regulations as they pertain to post-processing in general.
