LSH 19.09.17

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 directed energy deposition (DED).

With that said, in this report, we look at the common post-processing steps for DED 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 directed energy deposition 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 standard and regulations as they pertain to post-processing in general.
