Special Issue Information

Dear Colleagues,

When it comes down to a material with desired properties in tissue engineering, hydrogels exceedingly outperform other candidates in the field by providing higher biological compatibility, cell desired water content, and facile tunability towards more biologically desired niches for cell proliferation and differentiation. Despite the great advances in the hydrogels’ physical and chemical properties, one big hurdle for their clinical translation is the inferiority/absence of proficient manufacturing processes. This process should be able to transform an optimized hydrogel to the final biological construct with high resolution of cells and biomaterials and perfectly matched architecture mimicking the native one. In this respect, 3D/4D bioprinting is known as a manufacturing process with great potential. Bioprinting is an additive manufacturing process through which functional living constructs with desired architectural complexity are produced by the precise deposition of hydrogels, living cells, and biological factors. This Special Issue, entitled 3D and 4D Printing of Hydrogels for Tissue Engineering, covers advances and novel methodologies in 3D/4D bioprinting of bioactive hydrogels for tissue engineering application. Notably, this issue also covers pure theoretical modeling whose results advances the respected field.

We cordially invite you to submit your original research article or review paper to this Special Issue by the 15 October 2022.

Hydrogel has become a commonly used material for 3D and 4D printing due to its favorable biocompatibility and low cost. Additive manufacturing, also known as 3D printing, was originally referred to as rapid prototyping manufacturing. Variable-feature rapid prototyping technology, also known as 4D printing, is a combination of materials, mathematics, and additives. This study constitutes a literature review to address hydrogel-based additive manufacturing technologies, introducing the characteristics of commonly used 3D printing hydrogel methods, such as direct ink writing, fused deposition modeling, and stereolithography. With this review, we also investigated the stimulus types, as well as the advantages and disadvantages of various stimulus-responsive hydrogels in smart hydrogels; non-responsive hydrogels; and various applications of additive manufacturing hydrogels, such as neural catheter preparation and drug delivery. The opportunities, challenges, and future prospects of hydrogel additive manufacturing technologies are discussed. Full article
