Abstract: A support fixture is provided for forming a three dimensional article of manufacture onto a lower build surface thereof. The formation of the three dimensional article occurs in a resin vessel containing photocurable resin. The resin vessel includes a transparent sheet that forms a lower bound for the resin. The support fixture includes an interface fixture and a replaceable support. The interface fixture includes an upper portion having alignment and gripping features, a lower portion surrounding a central opening and including a plurality of attachment features, and a side wall coupling the upper and lower portions. The replaceable support includes a planar portion having a lower surface (providing the lower build surface) for attachment of the three dimensional article of manufacture and a peripheral support portion including complementary attachment features engaging the attachment features when the peripheral support portion is mounted to the lower portion of the interface fixture.
