Abstract: Methods and apparatuses (400) suitable for use in 3D-printing of gels from a solution (470) comprising a polymerizable material dispersed in a solvent are described. Such methods and apparatuses (100) include features (493) to control the relative saturation of the solvent in a gas phase region around the gel during the 3D-printing process.
