A method of making a three-dimensional object from a volume of photohardenable material contained in a photohardenable material container, the photohardenable material container having a bottom defined by a photohardening inhibitor delivery device, the photohardening inhibitor delivery device comprising a photohardening inhibitor reservoir comprising an inlet channel in fluid communication with a continuous chamber, the continuous chamber having an open top and a plurality of supports; and a flexible film that is permeable to the photohardening inhibitor and attached to the photohardening inhibitor reservoir, the flexible film having a first side that faces the continuous chamber, and a second side that faces away from the continuous chamber, wherein the flexible film encloses the open top of the continuous chamber, and each support is attached to the film such that the photohardenable material is in contact with the flexible film at a film/material interface, the method comprising: supplying the photohardening inhibitor through the continuous chamber and to the flexible film such that the photohardening inhibitor permeates the flexible film; immersing a previously formed exposed object surface into the volume of photohardenable material such that the previously formed exposed object surface is spaced apart from the flexible film; supplying solidification energy in a pattern corresponding to a cross-section of the three-dimensional object through the flexible film to form a currently formed exposed object surface that is spaced apart from the flexible film, wherein during the step of supplying solidification energy, the photohardening inhibitor prevents the photohardenable material from solidifying within a zone of non-solidification that includes the film/material interface, wherein the photohardening inhibitor reservoir is formed from a polydimethylsiloxane (PDMS), and/or each support has a height and a cross-sectional area perpendicular to the height, the continuous chamber has a height parallel to the support height and an area parallel to the support cross-sectional area, and the supports occupy from about one to about 50 percent of the continuous chamber area. supplying the photohardening inhibitor through the continuous chamber and to the flexible film such that the photohardening inhibitor permeates the flexible film; immersing a previously formed exposed object surface into the volume of photohardenable material such that the previously formed exposed object surface is spaced apart from the flexible film; supplying solidification energy in a pattern corresponding to a cross-section of the three-dimensional object through the flexible film to form a currently formed exposed object surface that is spaced apart from the flexible film, wherein during the step of supplying solidification energy, the photohardening inhibitor prevents the photohardenable material from solidifying within a zone of non-solidification that includes the film/material interface, wherein the photohardening inhibitor reservoir is formed from a polydimethylsiloxane (PDMS), and/or each support has a height and a cross-sectional area perpendicular to the height, the continuous chamber has a height parallel to the support height and an area parallel to the support cross-sectional area, and the supports occupy from about one to about 50 percent of the continuous chamber area.
