Abstract
An 3D printer has a gantry configured to move in a plane substantially parallel to a build plane. The system includes a platen configured to support a part being built in a layer by layer process, wherein the platen is configured to move in a direction substantially normal to the build plane. The system includes a head carriage carried by the gantry wherein the head carriage includes a first support member supporting a retaining mechanism. The retaining mechanism includes at least one member extending from the support member and a camming member rotatably attached to the support member and movable about an axis of rotation. The camming member has arcuate camming surface with an increasing radial distance from the axis of rotation. The system includes at least one print head having a housing with a first side surface configured to engage the at least one member and a second side surface configured to engage the arcuate camming surface. The camming member is positionable between a first, non-engaging position where the at least one print head is removable from the support member and a second, engaging position wherein the camming member engages the second side of the print head and t…
