Full-automatic microelectronic printer comprising a printing platform, a control component, a feeding component, a camera component, a machine vision device, an ink droplet observation device, and a CAD/CAM system. The printing platform comprises a four-axis linkage system, a printing worktable, a base, a protective housing, an automatic ink cartridge turning device, and an automatic cleaning device; the feeding component comprises a switching control device, an ink cartridge, and an auxiliary processing component; the control component comprises a core control integrated circuit board, a plurality of drive control circuit boards, and a control module interface. The feeding component switches the ink cartridges and the auxiliary processing components to the printing platform in response to the control component which drives the ink cartridges and auxiliary processing components to print, and the protective housing removes fine particles and gas odors. CAD/CAM system assists in designing, generating, and sending instruction to the control component, printing platform, and feeding component to operate and realize full-automatic multi-layer printing.

Disclosed is a 3-D printing apparatus. The apparatus includes an ink output module including an ink supply unit having an ink for forming an electrode portion, electrolyte or packaging portion received therein and an ink discharge unit coupled to the ink supply unit; a driving unit having the ink output module mounted thereon to move the ink output module in an X, Y, Z axis direction with respect to a substrate where a supercapacitor or secondary battery will be formed; a dispenser connected to the ink supply unit to supply gas having controlled pressure to the ink supply unit through a gas supply tube and to supply the ink within the ink supply unit through the ink discharge unit; and a controller controlling the output of the ink by transmitting a control command for fabricating the supercapacitor or the secondary battery to the dispenser and the driving unit.

Systems and methods for forming an object using additive manufacturing. One method includes receiving a digital model of the object, predicting a shrinking characteristic or receiving a predicted shrinking characteristic of the object that will occur during thermal processing of the object, once formed, and generating, based on the shrinking characteristic of the object, instructions for forming a raft on which the object will be formed. The instructions for forming the raft are configured to form a raft having a shrinking characteristic that reflects the shrinking characteristic of the object.

A three-dimensional printing system includes a print bed and a shelf insertion mechanism for inserting a shelf of one or a plurality of auxiliary shelves into a print volume between the print bed and a printer head. A printer assembly is configured to deposit layers of material within the print volume to form one or more objects on a support platform, the support platform including the print bed or an auxiliary shelf that is inserted into the print volume by the shelf insertion mechanism. A controller is configured to control the shelf insertion mechanism to insert an auxiliary shelf between the print bed and a printer head of the system after formation of the objects on that support platform by the printer assembly is complete.
