1. An additive manufacturing apparatus, comprising:
- a build enclosure having an upper platform defining a planar worksurface and an inner side wall extending downwardly from the upper platform, the inner side wall defining a build chamber;
an actuator in sealing engagement with the inner side wall;
a build platform releasably secured to the actuator; and
at least one lifting pin mounted to the build enclosure and positioned so as to separate the build platform and the actuator in response to movement of the actuator.

12. An additive manufacturing apparatus, comprising:
-
a build enclosure having an upper platform defining a planar worksurface and an inner side wall extending downwardly from the upper platform, the inner side wall defining a build chamber; an actuator in sealing engagement with the inner side wall; a build platform releasably secured to the actuator; and a platform lift carried by the actuator and configured to selectively separate the build platform and the actuator, thereby creating an opening between the build platform and the actuator, wherein the platform lift includes; a sliding sleeve moveable between upper and lower positions relative to the actuator; and at least one pin connected to the sliding sleeve and extending upwardly through an opening in the actuator. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
