Abstract: Methods of printing using three dimensional printers are disclosed. The method includes feeding a printable material through a linear feed mechanism to a print head, detecting the printable material is jammed in the three-dimensional printer, and operating, in response to detecting that the printable material is jammed, the three-dimensional printer in a jam clearing mode. The jam clearing mode includes advancing a drive component of the linear feed mechanism, retracting the drive component of the linear feed mechanism, and repeating the advancing and retracting of the drive component of the linear feed mechanism. Three-dimensional printing systems are also disclosed. A three-dimensional printing system includes a print head, a linear feed mechanism operatively coupled to the print head, and a controller operatively coupled to the three-dimensional printing system.

Abstract: Method of manufacturing a metal matrix composite part and ceramic preform assembly for use in the method. The method includes forming a ceramic preform using 3D printing, sintering the ceramic preform to form a sintered preform, introducing a liquid metal into the sintered preform to form the metal matrix composite part. The ceramic preform may be part of a ceramic preform assembly includes at least one ceramic preform and an infiltrant reservoir connected to the ceramic preform. The method may also include forming the ceramic preform assembly using 3D printing.

Abstract: A 3D printing apparatus and method corrects for skew in the motion components of the apparatus without the use of an independent reference object. A calibration object having features therein or thereon is printed. A user rotates the calibration object by a certain angle after it is printed. The features in/on the calibration object are measured, and an amount of skew is determined based on the measurements. In addition, a 3D printing operation is compensated based on the effects of a coefficient of thermal expansion and/or moisture absorption on dimensional changes.

Abstract: A method of manufacturing a part formed of metal, a method of determining a ceramic support structure for the metal part, and an un-sintered metal part including the ceramic support. The method of manufacturing the part includes forming a metal part and forming a ceramic support by depositing a ceramic composite material in a pattern to form ceramic print layers. The ceramic support supports a supportable portion of the metal part. The method of determining the ceramic support structure for the metal part includes determining, (i) a composition of a ceramic filament used to produce the ceramic support or (ii) a geometry of an infill of the ceramic support such that the ceramic support has a strength sufficient to support the supportable portion prior to sintering and is deformable to allow the supportable portion to undergo geometric changes during sintering.

Abstract: A 3D printing apparatus and method includes a piezo actuator that reciprocates a tappet. The reciprocation of the tappet generates pressure within a chamber filled with molten print material. The generated pressure causes the molten print material to be extruded through a nozzle coupled to the chamber. The piezo actuator is controlled to switchably provide continuous extrusion of print material or extrusion of discrete droplets of print material.
