3D & 4D Printing in Engineering Applications, 2nd Edition

Dear Colleagues,

Over the last 20 years, 3D printing has greatly evolved. This applies to both the development of new additive manufacturing technologies and the chemistry of the materials used, increasing the metrological accuracy of manufactured objects by improving the design of 3D printers and optimizing the mechanical and tribological properties of manufactured objects. Currently, the range of materials used incorporates plastics, ceramics, and metals, including materials with very advanced properties. Three-dimensional printing using new intelligent materials, often based on composites, innovative design, and technological solutions, has evolved into the new concept of 4D printing. This method takes into account another, fourth dimension—time. The shape or properties of a structure can be changed via the implementation of 4D printing. Four-dimensional printing is a kind of new manufacturing philosophy based on four-dimensional printing.

After the initial success of the Special Issue of Materials on “3D & 4D Printing in Engineering Applications”, we are delighted to introduce this second edition.

The SI will publish innovative scientific research, review articles, and communications related to modern technologies of additive manufacturing and its materials, taking into account innovative tools that also fit into the realities of industrial transformation towards Industry 4.0. The presented Special Issue aims at the publication of the results of both theoretical and experimental research, including research on the following areas:

• 3D/4D printing;
• Rapid prototyping
• Unconventional manufacturing;
• Metrology in 3D printing;
• Surface texture analysis;
• Quality of 3D/4D printed parts;
• Tribology in 3D printing;
• Mechanical properties investigation;
• Thin-walled models
• Cellular structures
• Composites materials;
• 3D/4D printing engineering applications;
• 3D printing in Industry 4.0 and 5.0;
• Robotics in 3D printing;
• Novel 3D printing systems;
• Review of progress in 3D/4D printing;
• Manufacturing problems;
• Machining of 3D printed elements;
• Process control;
• Simulation analysis.

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.
