Medical 3D Printing & Bioprinting
Aether 1 bioprinter is one of the 3D Bio-Printers that is capable of printing two bones connected by a tendon using six materials that include synthetic bone, conductive ink, stem cells and graphene oxide. When usual bio-printers may cost upto 200,000$, the Aether 1 Bio-printer costs only 9000$ and they will be rolled out soon after some donations to researchers and universities.
