Advances in Additive Manufacturing: Materials, Processes, and Applications

Dear Colleagues,

Additive manufacturing (AM), also known as 3D printing, has undergone rapid advancements in recent years, revolutionizing industries such as aerospace, healthcare, energy, and automotives. These advancements span across material development, process innovation, and novel applications, enabling AM to move beyond prototyping into full-scale manufacturing.

The continuous evolution of AM has led to the development of novel materials, enhanced processing techniques, and improved quality control measures. Furthermore, emerging technologies such as AI-driven material development and process optimization, hybrid manufacturing, and in situ monitoring are transforming the AM landscape, pushing the boundaries of design complexity, mechanical performance, and functional integration.

In this Special Issue, we invite state-of-the-art reviews and original research contributions that explore recent advances in AM materials, processes, and applications. Topics of interest include, but are not limited to, the following:

• Innovative materials for additive manufacturing (metals, polymers, ceramics, composites, and functionally graded materials);
• New and hybrid AM processes for enhanced performance, efficiency, and scalability;
• New applications of AM in the aerospace, biomedical, energy, electronics, and emerging industries;
• Advanced characterization techniques for AM processes and AM-fabricated materials and structures;
• Intelligent process optimization and adaptive control strategies (artificial intelligence, machine learning, in situ monitoring, close-loop control, and digital twins);
• Sustainability and recyclability in AM materials and processes;
• Advanced simulations for mechanistic study in AM (finite element modeling, computational fluid dynamics, density functional theory, and the calculation of phase diagrams).

This Special Issue aims to provide a comprehensive perspective on the latest developments in AM, promoting discussions that bridge material science, engineering, and industrial applications.

We look forward to your valuable 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 250 words) can be sent to the Editorial Office for assessment.

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.
