Abstract: A housing includes a base layer, a primer layer formed on the base layer, an ink jet coating layer formed on the primer layer, and a protection layer formed on the ink jet coating layer. A method for manufacturing the housing is also provided.

Abstract: A method for printing a label on a keypad, including the steps of providing a substrate plate, spraying ink on the substrate plate to form a label layer, solidifying the label layer, spraying ink around the label layer to form a primer layer, and solidifying the primer layer.

Abstract: An inkjet printer includes an inkjet cartridge, an inkjet head, a controller, a viscosity adjustment device and a viscometer. The inkjet cartridge is filled with ink. The inkjet head is connected to the inkjet cartridge. The catcher plate is opposite to the inkjet head, and connected to the cartridge. The viscometer is configured for determining a viscosity of ink in the inkjet cartridge. The viscosity adjustment device is configured for adjusting viscosity of ink in the inkjet cartridge. The controller is electrically connected to the inkjet head, the viscometer, and the viscosity adjustment device, respectively.

Abstract: A three-dimensional continuous printing method on a workpiece positioned on a rotation mechanism is described. The rotation mechanism rotates the print area of the surface of the workpiece to face the inkjet head of the printer. The inkjet head of the printer prints on the print area of the surface of the workpiece. A selection of additional print areas is offered. If the selection is requested, the rotation mechanism rotates the workpiece such that the desired print area faces the inkjet head of the printer, and selection of the other print area of the workpiece for print is confirmed. If not, the printing process is completed.

Abstract: A method for printing on a curved surface includes determining if a surface of a workpiece is curved, cutting an image to be printed into at least two printing areas if the surface is curved, and printing the printing area of the image on each surface of the workpiece. If the surfaces of the workpiece are not curved, the printing system directly prints the image on the workpiece. The printing system includes a rotating mechanism and a printer including an inkjet head having a plurality of nozzles. The workpiece is positioned on the rotating mechanism. The rotating mechanism rotates each surface of the workpiece to face the inkjet head and the inkjet head prints each printing area on it.

Abstract: A bio-degenerable bone cement is made of a mixture of poly (propylene fumarate) (PPF) and a diphasic material of tetra-calcium phosphate (TTCP)/dicalcium phosphate anhydrous (DCPA). The bone cement produced by a manufacturing method is injectable, bio-degenerable and non-penetrable to radioactive rays and features the advantages of a compressive strength close to the strength of bones, a low polymerization temperature, and a high biological compatibility.
