Novel Applications of Additive Manufacturing Technology for Functional Materials and Composite Materials

Dear Colleagues,

Additive Manufacturing (AM) has revolutionized production by enabling complex 3D structures using advanced materials—including polymers, metals, ceramics, and composites—while promoting sustainability through resource efficiency and reduced environmental impact. Its main applications range from medical devices and customized implants to functional composites for the aerospace and automotive industries, as well as specialized military equipment on demand. In the automotive and aerospace sectors, AM technology drives sustainability by reducing component weight, saving natural resources, minimizing raw material waste, and optimizing logistics costs. At the same time, it allows for the creation of complex geometries with innovative materials, such as high-entropy alloys and shape-memory polymers. The rise of AM has also paved the way for the manufacturing of advanced ceramics, such as Silicon Carbide and Silicon Nitride, and fiber-reinforced composites. In the pharmaceutical industry, AM has enabled the reinvention of pharmaceutical forms, facilitating the creation of polypills, chewable tablets, and gastro-floating devices. In tissue engineering and bioengineering, the use of hydrogels and biocompatible polymers makes it possible to create cell- and tissue-laden scaffolds for regenerative medicine. In the area of prosthetics, AM technology has enabled metallic implants with intricate geometries via laser fusion or electron beam, serving the orthopedic, dental, neurological, and cardiac fields. Furthermore, actuators printed with hydrogels or liquid crystal elastomers can mimic biological movements by reacting to electric fields, light, or pH variations. In the defense and construction fields, AM has replaced traditional techniques with 3D printing rapidly manufactured weapons and structures, as well as customized high-performance protective equipment such as helmets and footwear. Finally, advanced AM design allows for the conception of highly complex structures, such as cellular networks and metamaterials with programmed physical properties.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences 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 2400 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.
