Removable build plate with evenly heated build surface of 3D printer

A build platform for a three-dimensional (3D) printer that is configured to synthesize 3D objects by extruding layers of filament onto a build surface of a build plate, the build platform comprising:

• a base;
• a heating layer;
• at least one compressible biasing element arranged between the base and the heating layer;
• and
• a clamp;
• wherein the build platform is configured for receiving the build plate into a clamping position in which the clamp is configured to releasably clamp the build plate onto the build platform above the heating layer, causing the at least one compressible biasing element to compress and bias the heating layer upwards towards the clamped biasing build plate for even distribution of heat by the heating layer over a planar extension of the build surface.

A build plate including a build surface for a three-dimensional (3D) printer that is configured to synthesize 3D objects by extruding layers of filament onto the build surface of the build plate, the build plate comprising:

• a glass center build region;
• and
• a plastic build frame surrounding the center build region, wherein the build frame includes:
• a first groove in a front edge of the build plate, at or near a first front corner of the build plate;
• a second groove in the front edge of the build plate, at or near a second front corner of the build plate;
• a first protrusion at or near the first front corner, protruding laterally from a first side edge of the build plate in a first direction away from the grooves;
• and
• a second protrusion at or near the second front corner, protruding laterally from a second side edge of the build plate in a second direction away from the grooves.
