Abstract: Systems and methods of additively manufacturing leak resistant objects are disclosed. Provided herein are methods of forming objects having walls and/or surfaces that are resistant to leaks. Objects disclosed are formed from or manufactured from compositions, including metals, polymers, and combinations thereof. Objects provided herein are made from methods of forming individual shells, forming of series shells, and layer-by-layer forming of objects. Further disclosed are methods of interconnecting shells, layers, and processes for transitioning therebetween the shells and layers.

Abstract: Systems, apparatus and methods of additively manufacturing objects are disclosed. Specifically, provided herein are methods of heating objects having a particle-based support at least partially surrounding the object during portions of stages of the heating. Additionally, systems, apparatus, and methods for removing the particle-based support during heating, such that the object can continue heating to form a final part. Systems, apparatus, and methods for distributing the particle-based support to shore the objects through heating are disclosed. Systems, apparatus, and methods for removing the particle-based support are also disclosed herein.

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.
