Special Issue Information
Dear Colleagues,
Additive manufacturing technology, also known as 3D printing technology, is different from traditional processing methods. By printing the material layer by layer in a certain way, the parts and cavities that cannot be formed by traditional processing methods can be obtained. The parts formed by additive manufacturing can be comparable with the parts produced by traditional process in some mechanical properties, so they are widely used in aerospace, biomedical and other fields, and gradually show their great advantages in mold, gear, automobile manufacturing and other industrial fields.
Although additive manufacturing technology has many advantages, it also has some disadvantages due to its processing principle and forming mode. For example, there are defects such as "powder adhesion" and "spheroidization effect" on the surface of parts after forming, which will lead to the increase of surface roughness. Therefore, many scholars have carried out a large number of experimental studies. At present, the common solutions include optimization of 3D printing manufacturing parameters, heat treatment of formed parts, hot isostatic pressing treatment and other methods to improve the surface quality of the workpiece and refine the internal structure. On the other hand, the workpiece surface roughness can be reduced by machining, thus reducing the stress concentration and improving the fatigue life of parts.
There are many other additive manufacturing finishing techniques and applications. The field is rapidly expanding into new areas of discovery.
It is my pleasure to invite you to contribute to this special issue. Full papers, newsletters and reviews are welcome.

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. Materials is an international peer-reviewed open access semimonthly 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 2600 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.
