A method of making a three-dimensional object, comprising the steps of: (a) providing a carrier and an optically transparent member having a build surface, said carrier and said build surface defining a build region therebetween, said optically transparent member carrying a polymerizable liquid ; (b) advancing said carrier and said optically transparent member away from one another to draw said polymerizable liquid into said build region; then (c) optionally, partially retracting said carrier and said optically transparent member back towards one another; and then (d) irradiating said build region with light to form a growing three-dimensional object from said polymerizable liquid ; and then (e) cyclically repeating steps (b) to (d) while maintaining a continuous liquid interface between said growing three-dimensional object and said optically transparent member until at least a portion of said three-dimensional object is formed, while during at least some of said cyclically repeatings: (i) monitoring a transient increase in tension between said carrier and said build surface through said growing three-dimensional object during said advancing step (b), and optionally monitoring a transient increase in compression between said carrier and said build surface through said growing three dimensional object during said partially retracting step (c); and then, when said transient increase in tension has substantially subsided, (ii) initiating said partially retracting step (c) when present, or initiating said irradiating step (d).
