1. 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;
a base assembly removably coupled to the removable build plate; and
an alignment module including an electromagnet housed inside the base assembly adapted to magnetically move the removable build plate along a surface of the base assembly such that the removable build plate automatically self-aligns along a perimetrical edge of the base assembly and magnetically couples to the base assembly.
