Instead of starting with metal, plastic, or ceramic, a 3-D printer for organs and tissues uses bioink: a printable material that contains living cells.
普通的 3D 打印机使用金属、塑或陶瓷,而制作器官和组织的 3D 打印机使用“生物墨水”:一种含有活细胞的可打印。
If the current trend of Open Source 3D printable files continues, it will not be long before everyone prints their own large objects, like furniture and weapons.
