Special Issue Information
Dear Colleagues,
The use of binder material to facilitate shaping when metal powders are used is usual in most powder manufacturing techniques: powder injection molding, powder hot-embossing, binder jetting, and material extrusion (such as FFF and FDM). Usually, these techniques require different process steps: selection and characterization of materials, optimization and production of mixtures, shaping, debinding, and sintering. These process steps are related, and the variables of each one interact and influence the properties of the final parts. The success of the replication of final parts depends on the characteristics of the powder and binder. The binder has an essential role in the homogeneity of the mixture, shaping process, and the interaction with powders during debinding. Simulation of the behavior of the materials is interesting to optimize the processing conditions and provide competitiveness. For industrial application, both the binder materials and the removal processes of these binders must be environmentally friendly. Moreover, post-processing (HIP, heat treatments, finishing, etc.) are relevant to enhance properties and to achieve requirements. The development of metal components produced by these techniques should be productive and competitive with others, whether for large series production or small batches. Topics addressed in this Special Issue may include, but are not limited to the following:
Powder and binder specified for PIM or Additive manufacturing using binder assisted method;
Molding/shaping powder-binder;
Debinding and Sintering;
Post-processing;
Numerical analysis of materials behavior to optimize processing conditions;
Industrial applications.

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. Metals 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 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.
