Proposed Scope: 1.1 This document describes bioinks and biomaterial inks used in biofabrication technology. 1.2 This guidance document provides ranges of material properties and compositions that promote survival of living cells contained bioinks. 1.3 The use of materials as inks to support bioink printing by providing mechanical support or as sacrificial materials to provide porosity is described. 1.3 Methods of 3D bioprinting that this standard may apply to include laser-assisted bioprinting, inkjet bioprinting/droplet bioprinting, and extrusion-based bioprinting. 1.4 The values are stated in SI units. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, is any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The field of biofabrication is a subset of additive manufacturing that is expanding rapidly. Within the field of biofabrication, bioprinting refers to the synthesis of living tissues using 3D printing techniques for applications within regenerative medicine and drug testing. As an emerging field there is a need for an umbrella document that can define terminology and important issues that may impact performance, reproducibility and quality control.
