Zusammenfassung:	Methods, systems, and/or apparatuses for making an object on a bottom-up stereolithography apparatus that includes a light source, a drive assembly, optionally a heater and/or cooler, and a controller. The light source, optional heater and/or cooler, and/or the drive assembly have at least one adjustable parameter that is adjustable by said controller. An example method comprises (a) installing a removable window cassette on said apparatus in a configuration through which said light source projects, said window cassette comprising an optically transparent member having a build surface on which an object can be produced, and with said optically transparent member having at least one thermal profile associated therewith; and then (b) modifying said at least one adjustable parameter by said controller based on said at least one thermal profile of said optically transparent member; and then (c) producing the object on said build surface from a light-polymerizable liquid by bottom-up stereolithography.
