Special Issue Information

Dear Colleagues,

The 4D printing technology enables printed objects to achieve predefined deformation and functional changes when subjected to external stimuli (e.g., temperature, humidity, light or electric field, etc.) through smart materials.

This technology not only possesses the advantages of 3D printing for the flexible manufacturing of complex structures but also gives printed objects the ability to respond dynamically, bringing innovative solutions to various fields.

Given the growing importance of 4D printing, this Special Issue aims to report the latest advances at the forefront of this promising technology. It welcomes not only original research articles that advance the knowledge of 4D printing but also encourages review articles that aim to present the state-of-the-art literature.

Possible topics include the following:

  • 4D printing;
  • Innovative application;
  • Soft robot;
  • 3D printing;
  • Multi-material 3D printing;
  • Shape Memory Polymers;
  • Shape Memory Alloys;
  • Hydrogel;
  • 4D printing of mechanical metamaterials.

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. Machines 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 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.

Conventional energy-absorbing components have limited adjustability under complex working conditions. To overcome this limitation, we designed a bio-inspired sinusoidal metamaterial (BSM) inspired by the efficient energy-absorbing structure of the mantis shrimp jaw foot and 4D printed it based on shape-memory polymer (SMP). The effects of single-cell structural parameters and gradient design on its force–displacement curves and energy-absorbing properties were explored. Based on the shape memory effect of SMP, the BSM can obtain arbitrary temporary shapes under the combined effect of temperature and force, realizing locally controllable compression deformation and programmable mechanical properties of the BSM structure. This research has a broad application prospect in the field of energy absorption and energy management and provides new ideas for the design of smart structural materials. Full article
