Special Issue Information

Dear Colleagues,

The use of additive manufacturing technologies has opened the way to new design routes with all classes of materials.

They are particularly promising in the biomaterials field, where they allow producing highly personalized regenerative medicine components: for instance, customized 3D scaffolds may be combined with stem cells for tissue engineering or bone replacement, or for the regeneration of complex organs with an intricate 3D microarchitecture.

For each of these applications, specific structural and functional properties are requested: how can materials be combined to answer to these specific requests?

This Special Issue aims to address the current state of the art of additive manufacturing of multimaterial components. What are the open challenges at the scientific and technological level? Will multimaterials 3D printing be able to open the way to a new generation of highly personalized regenerative medicine? What are the main issues to be solved before industrialization takes place?

It is my pleasure to invite all colleagues to submit manuscripts (full papers, reviews, or short notes) in open access to this Special Issue. I also encourage the dissemination of this invitation to any colleagues who might be interested.

Dr. Lisa Biasetto
Guest Editor

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.

This paper investigates the spreadability of the spherical CoCrWMo powder for laser- powder bed fusion (PBF-LB) by using image processing algorithms coded in MATLAB. Besides, it also aims to examine the spreadability dependence with the other characteristics such as powder size distribution, apparent density, angle of repose. Powder blends in four different particle size distributions are prepared, characterized, and spreadability tests are performed with the PBF-LB. The results demonstrate that an increase in fine particle ratio by volume (below 10 µm) enhances the agglomeration and decreases the flowability, causing poor spreadability. These irregularities on the spread layers are quantified with simple illumination invariant analysis. A clear relation between powder spreadability and 3D printed structures properties in terms of residual porosity could not be defined since structural defects in 3D printed parts also depends on other processing parameters such as spatter formation or powder size over layer height ratio.
