About this Research Topic
Additive manufacturing (AM) has found widespread use in various fields, such as aerospace, biomedical, mechanical equipment, etc. AM technology encompasses both 3D printing and 4D printing. 3D printing is now an established technology with both researchers and engineers, but 4D printing is rapidly growing. 4D printing means that a 3D-printed part can change its shape or properties with time when it is stimulated by external fields, such as thermal, light, or moisture; thus it is now attracting widespread attention around academia and industry. It has enormous application prospects such as in sensors, robots, etc. However, the variety of materials that can be 3D or 4D printed is still limited because many conventional shape memory (SM) materials could not be printed to form a SM part and still maintain its SM functionality. Thus, more research is needed to focus on the properties and structures of new printable materials.
This Research Topic welcomes contributions on novel 3D and 4D printable materials, particularly how their structure influences the properties of 3D/4D-printed parts. Theoretical studies and simulations of 3D/4D-printed materials are also encouraged. Some 3D and 4D printable materials of interest include:
• Shape memory materials
Keywords: additive manufacturing, 4d printing, 3d printing, shape memory materials
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
