Special Issue Information
Dear Colleagues,
State-of-the-art metal additive manufacturing (AM), or 3D printing, allows for the fabrication of complex, near-net-shape geometries and the realization of more efficient and lightweight designs, more sustainable part manufacturing, rapid prototyping, and reduced machining costs. Despite the many advantages of AM methods, metal parts produced by AM generally do not achieve the same structural integrity and mechanical properties of wrought parts due to the development of high residual stresses and, possibly, the formation of detrimental phases and defects. In addition to optimizing the AM process conditions, post-processing operations, including thermal and thermomechanical treatments, are often employed to relieve the residual stresses, refine the microstructure, and improve the quality and properties of metallic parts produced by AM.
This Special Issue aims to provide a forum for researchers and practitioners from academia and industry to publish their experimental and theoretical results on post-processing for additive manufacturing and to contribute to the quality improvements and rapid application of additively manufactured parts. It is our pleasure to invite you to submit your contributions with a special focus on:
- Cold working and annealing;
- Heat treatment;
- Thermomechanical treatment (including warm/hot deformation and hot isostatic pressing);
- Laser post-processing;
- Hybrid post-processing routes combining additive and subtractive operations;
- Porosity and microstructure evolution (grain size and texture) during post-processing;
- Variations in mechanical and functional properties after post-processing;
- Sustainability issues in post-processing.
We look forward to receiving your contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
