Abstract: A three-dimensional printer includes an inkjet head and a nozzle plate. The inkjet head includes a top wall and two sidewalls connecting with the top wall. The top wall of the inkjet head includes a top nozzle. Each sidewall includes a side nozzle. The nozzle plate is positioned on an inner surface of the inkjet head. The nozzle plate includes a top area and two opposite side areas connecting with the top area. The top area of the nozzle plate includes a plurality of holes corresponding to the top nozzle of the inkjet head. Each side area of the nozzle plate includes a plurality of holes corresponding to the side nozzle of the inkjet head.

Abstract: An inkjet printing apparatus includes an inkjet print-head, an ink inlet conduit, a vacuum device, and a cleaning assembly. The inkjet print-head defines a number of nozzles. The ink inlet conduit is connected to the inkjet print-head and communicates with the nozzles. The cleaning assembly includes a cleaning member defining a cleaning groove. The vacuum device is connected to the inkjet print-head to impel cleaner received in the cleaning groove to flow through the nozzles along a direction reverse of a direction the ink is jetted.

Abstract: A three-dimensional printing device includes a top bracket, a side bracket, and a pivoting member. The top bracket includes a pair of sidewalls cooperatively defining a receiving space to receive an inkjet head. The side bracket includes a pair of sidewalls cooperatively defining a receiving space to receive the top bracket. The pivoting member includes a pair of sidewalls cooperatively defining a receiving space to receive an inkjet head. The pivoting member is rotatably mounted in the receiving space of the side bracket.

Abstract: An ink-jet device for jetting ink on an outer surface of a workpiece, includes an ink jet head including a nozzle, a fixing platform to fix the workpiece, a pair of light sources for emitting light to heat ink from the nozzle, and one or more reflection assemblies positioned on opposite sides of the fixing platform and below the ink jet head. The light sources are positioned in the corresponding reflection assembly. Each of the reflection assembly reflects light to be transmitted parallel to the nozzle, for heating and drying the ink on the outer surface of the workpiece.

Abstract: An inkjet head includes a main body, a film, a piezoelectric atomizer, a cover and a nozzle plate. The main body includes a cavity receiving a fluid with an opening connecting the cavity. The cover is fastened to a top end of the main body. The film is interposed between the cover and the main body. The nozzle plate includes a plurality of nozzles. The nozzle plate is disposed on a bottom end of the main body. The piezoelectric atomizer is interposed between the cover and the film. The piezoelectric atomizer introduces pressure variations in a static pressure to atomize the fluid.
