Three-Point Leveling Platform for Stereolithography Apparatus

      This disclosure describes a design using three-point mounting
for supporting and leveling the platform for the StereoLithography
Apparatus.

      The StereoLithography Apparatus combines chemistry, laser
physics and computer control to convert a 3D computer model into a
prototype plastic part.  One key factor in building good parts is the
level alignment of the platform with respect to the surface of the
resin in the vat.

      The disclosed design consists of a triangular aluminum plate
(1) with posts (2) and coiled springs (3) at each corner.  The
platform is connected to the elevator at two posts (4).  The
perforated platform is placed over the posts, with the holes in the
platform aligning with three posts.  The springs provide support for
the platform.  Screw caps (6) at each corner can be used to
tighten/loosen the platform as required.  The platform will have two
degrees of freedom - rotation around the x or y axes (7).  The
operator can quickly and accurately level the platform relative to
the resin surface.  Also, the platform is easy to install/remove.
