Special Issue Information

Dear Colleague,

It is well known that hydrogels are typical soft materials consisting of a hydrophilic three-dimensional polymer network and a large amount of water, and have been widely used in flexible electronics, soft robotics, drug delivery and biomedical applications. Hydrogels can usually only be fabricated into two-dimensional or simple three-dimensional structures by the template method in conventional manufacturing processes, which severely limits their application prospects. Recently, 3D printing technology has gained much attention because of its ability to quickly convert digital designs into complex structures on demand. The customized 3D manufacturing of hydrogels can be thoroughly explored in combination with 3D printing technology, which is expected to enable the application of hydrogels in a wider range of fields.

However, hydrogel precursors are often difficult to use directly for 3D printing. Most of the initial hydrogel precursors need to be adapted to 3D printing techniques. Therefore, it is important in the study of 3D-printed hydrogels to maintain their functionality as much as possible without losing printing performance and to print hydrogels with a higher water content.

This Special Issue focuses on the recent progress in 3D printing of hydrogels. Relevant topics include, but are not limited to, theoretical and experimental studies, mechanical properties, rheological properties, self-healing properties, electrical conductivity, biological properties, thermal properties, structural characterization, fabrication methods and 3D printing processes.

Manuscript Submission Information

Manuscripts should be submitted online at 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. Gels 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 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.
