Special Issue Information
Dear Colleagues,
The advent of three-dimensional (3D) printing brings about the possibilities of designing functional materials based on their structures as opposed to their chemistry. Specifically, these materials are designed with the introduction of architectured pores, and they are also porous and periodic in nature. A new class of material, known as lattice structure, manifests from this. Various types of lattice structures, with features based on struts, shells, plates, and their hybrids, exist. Owing to their unique porous and cellular structure, they often display properties not commonly found in traditional bulk materials, such as being lightweight, with an usually low/high specific stiffness and strength, deforming with a stress plateau region, having a high specific surface area, with unique flow properties, and with meta-mechanical behaviors. For instance, they are most commonly used as structural and protective materials for them to be lightweight and with an energy-absorbing behavior derived from the stress plateau. For their reduced stiffness and strength, they are also used as artificial bone implants whereby their bone-matching mechanical properties help to overcome the problem of stress shielding. Their high specific surface area, which allows maximized mass interactions, in turn allows them to be used as electrochemical electrodes, membranes, and filters. For their designable fluid flow properties, they are also attracting attention as acoustic metamaterials. With virtually unlimited possibilities in structural design, and (3D printable) material selections/combinations, it is apparent that there is a lot more that we can discover when it comes to the potentials of functional lattice structures.
This Special Issue welcomes all articles related to the 3D printing of lattice structures, including to but not limited to their design, materials processing, applications and performance, and mechanisms. This Special Issue also aims to help to advance the scientific and technical understandings of 3D-printed functional lattice structures.

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.
