Claim 15:
16. A build platform for a stereolithographic printer, comprising:
a removable build plate having a build surface for building three-dimensionally (3D)-printed objects on the build platform and a first coupling surface;
a base assembly having a second coupling surface removably coupled to the first coupling surface; and
an alignment module adapted to magnetically move the first coupling surface along the second coupling surface such that the removable build plate automatically self-aligns along a boundary of the base assembly and magnetically couples to the base assembly, the alignment module comprising:
two or more first magnets disposed on the first coupling surface;
two or more second magnets disposed on the second coupling surface that correspond to but have opposite polarity to the two or more first magnets disposed on the first coupling surface; and
a raised edge coupled about a perimeter of the second coupling surface.
