The entanglements between social creativity, legal instruments and global policies become particularly clear in emerging technological fields where such relations are being established or improvised. In this paper, an analysis of such entanglements is delivered, focusing on 3D bioprinting. This technique amounts to the use of robotic, computer-controlled devices called bioprinters, with which bioactive structures are manufactured, with potential medical applications. Bioprinting has triggered manifold relations and processes here grasped with the concept of experimental space. It is claimed that the experimental space has several dimensions, three of which are analysed here. [---]
