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 the first side of the print head engages the at least one member and causes a frictional engagement therebetween.

Abstract: A hold and release platen system for use in extrusion-based additive manufacturing system includes a platen, a vacuum source and a pressurized air source. The platen has a surface including a plurality of holes therethrough. The vacuum source is configured to provide a vacuum through the plurality of holes, and the pressurized air source is configured to eject pressurized fluid through the plurality of holes. A method includes positioning a sheet substrate on the platen surface; pulling a vacuum through one or more holes in the platen surface to secure the sheet substrate; printing a part on the sheet substrate by moving a print head along a tool path and extruding material in the path; and ejecting pressurized air through the one or more holes to create an air bearing beneath the substrate thereby facilitating removal of the sheet substrate and the printed part from the platen.

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 carrying a first retaining mechanism and a second support member carrying a second retailing mechanism. The first and second retaining mechanisms are both configured to receive and retain the print head or the additional equipment wherein both the removable print head and the removable additional equipment have substantially a same interface with the head carriage. Non-limiting examples of addition equipment includes a blower configured to discharge a stream of heating or cooling gas, a light, a sensor, a laser, a contact chiller, a roller, a cutting instrument, a bead shaping instrument, a dispenser, a bead blaster, a camera and/or a vacuum.
