Abstract: A method for evaluating curing in an ink composition comprises depositing an ink composition on the surface of an object via a direct-to-object inkjet printing system to form a film thereon, the ink composition comprising a photoinitiator capable of initiating a free radical polymerization process in the ink composition upon the absorption of light to cure the deposited film; exposing, in-situ, the deposited film to light generated by a first source of light under conditions which initiate the free radical polymerization process to cure the deposited film; exposing, in-situ, the cured film to light generated by a second source of light under conditions which induce light absorption by unreacted photoinitiator in the cured film; measuring the absorbance of the cured film; and determining a degree of cure in the cured film from the measured absorbance and predetermined calibration data.

Abstract: A surface treatment system includes a holder configured to secure an object within the holder and a surface treatment device that is configured to treat a surface of the object within the holder with two types of surface treatments. The device is capable of producing a plasma or a flame at its nozzle for surface treatment. By controlling the materials supplied to the device and the way in which is operated, either a flame or plasma is produced. Thus, the surface treatment system is capable of treating a wide range of materials for printing by a direct-to-object printer.

Abstract: A print system and a method for confirming complete curing of a marking material are disclosed. For example, the print system includes a plurality of printheads arranged in a two-dimensional array, a curing light source, a curing confirmation system, a movable member to hold an object and a controller to control movement of the movable member to move the object past the array of printheads, to operate the plurality of printheads to eject the marking material onto the object as the object passes the two-dimensional array of printheads, to operate the curing light source to cure the marking material and to operate the curing confirmation system to confirm that the curing of the marking material is complete.

Abstract: A method for forming an ink jet printhead comprises processing an epoxy adhesive such that negative effects from physical contact with particular inks are reduced or eliminated. Conventional adhesives processed using conventional techniques are known to gain weight and squeeze out when exposed to certain inks such as ultraviolet inks, solid inks, and aqueous inks. An embodiment of the present teachings can include processing of a particular adhesive such that the resulting epoxy adhesive is suitable for printhead applications.

Abstract: A printer is configured with a surface treatment system having a holder configured to secure an object within the holder and a plurality of surface treatment devices. Each surface treatment device is configured to treat a surface of the object within the holder differently than each of the other surface treatment devices in the plurality of surface treatment devices. Thus, the printer is capable of treating a wide range of materials for printing by the direct-to-object printer.

Abstract: A support material for use in additive manufacturing includes greater than about 30 weight percent up to about 70 weight percent of a C12 to C18 fatty alcohol ethoxylate, about 30 weight percent to about 70 weight percent of a C16 to C22 fatty alcohol, and a tackifier, a transition temperature measured as the temperature immediately before phase change, based on viscosity measurement, is less than about 65° C. A system for additive manufacturing includes such a support material and a build material, the ratio of C12 to C18 fatty alcohol ethoxylate to C16 to C22 fatty alcohol is selected for property matching of the support material to the build material. A method of additive manufacturing includes providing such a system and printing via an inkjet printer the support material and the build material to provide a precursor to a three-dimensional printed article.
