3D printing, also known as additive manufacturing (AM), is defined as the process of building blocks layer-upon-layer, unlike subtractive technologies. Some advantages of 3D printing over traditional methods are the opportunity to manufacture complex architecture and produce less waste as well as to reduce the production time.

In bioprinting, different materials can be used: metals, ceramics or polymers. Depending on the target, it is more suitable to use one type of material or other. For example, in case of soft materials, the best choice by far for biomedical applications is the use of polymers and specially gel-based materials which can be resins, silicones or hydrogels.

The aim of the present special issue is to advance in the state-of-the-art of biofabrication field and materials that can be used for biomedical applications.
