Human CNS is a very vital component of body and any damage or injury to it can cause serious lethal and fatal consequences. So there is thus need to regenerate this system incase of injury and is currently the most challenging task due to difficult system and restricted regenerative capacity. 3D bioprinting has outgrowth as an advanced field in field of neural tissue engineering. Which has enabled researchers to develop novel 3D scaffolds with complicated architecture in an effort to alleviate challenges defining neural tissue engineering. Amongst all the possible treatment of neuro-regenerative treatment available, 3D scaffolds had gained immense potential due to the advantage of being highly alterable, promoting complete similarity to the native biological architecture. This high architectural similarity between printed constructs and in vivo structures is known to promote a greater capacity for repair of damaged nerve tissues. This article consists of advancements in several 3D bioprinting approaches in accordance with the emergence of 4D printing, which adds a dimension of transformation over time to traditional 3D printing.
