A 3D bioprinter could one day be used to print biological tissues on demand, for medical applications
3D printed tissues and organs are now closer - science news in brief

A group of UCLA researchers developed a device that can print biological tissues in three dimensions. The aim of this 3D bioprinter is to print artificial versions of real tissues to be used for surgeries and transplants. The printing is based on stereolithography (nice word, isn’t it?), a light-based process, and is controlled by a customized 3D printer. The researchers used hydrogels to create the scaffolding for the tissues. After creating several 3D structures, scientists implanted them in lab animals to check for biocompatibility. The implants were not rejected, giving hope that this method could one day be used to provide on-demand biological tissues.
