Initially developed with traditional photopolymers , VAM was quickly adopted as a tool within the biofabrication community to produce 3D tissue constructs. Most photopolymers currently adopted for VAM require a high molecular weight as one of the key design criteria for VAM bioinks includes physical gelation prior to print initiation . The printing process requires that individual voxels do not reposition while curing, which is most easily done by using materials which will hold the forming part in position, i.e. solids or semi-solid gels. Thermogelling, where physical crosslinks are formed upon a change in temperature, has been used to achieve this capability in both hydrogel and hard resin formulations .
