Claim 0:
1. An apparatus for making a stereolithographic object, the apparatus comprising:
a platform for making the stereolithographic object thereon and a material receiving surface, wherein in use a material for making the stereolithographic object is disposed therebetween;
a positioner operationally coupled to at least one of the platform and the material receiving surface, and operable to change a separation of the platform and the material receiving surface; and
a control system configured to:
create an apparatus deformation by moving the positioner in a first direction to a position associated with a desired separation of the platform and the material receiving surface then further moving the positioner in the first direction to increase the apparatus deformation; and
determine whether the apparatus deformation has relaxed such that the separation of the platform and material receiving surface is the desired separation, and if so determined, move the positioner to the position associated with the desired separation of the platform and the material receiving surface.
