  • Publication number: 20250073996
    Abstract: A 3D printer configured to print a 3D part includes an ejector having a nozzle that is configured to eject drops of a build material. The 3D printer also includes a build plate positioned below the nozzle. The drops land and solidify on the build plate to form at least a portion of the 3D part. The 3D printer also includes a first heater positioned under or within the build plate. The first heater is configured to heat the build plate and the 3D part thereon. The 3D printer also includes a second heater positioned laterally-offset from the build plate. The second heater is configured to heat a volume of air between the nozzle and an upper surface of the 3D part. The 3D printer also includes an enclosure. The nozzle, the build plate, the first heater, and the second heater are positioned at least partially within the enclosure.

  • Patent number: 12043752
    Abstract: The present teachings include a flow coating solution, a fuser member and an image forming apparatus. The fuser member includes a substrate and flow coating solution applied onto the substrate. The outer layer includes a flow coating solution including a fluoroelastomer, a nucleophilic crosslinking agent and a non-functional polydimethylsiloxane having the formula: wherein n is from 100 to 20,000. The flow coating solution includes an effective solvent selected from the group consisting of N-methyl 2-pyrrolidone, dimethyl formamide, and dimethyl sulfoxide.

  • Patent number: 9606484
    Abstract: An improved fuser includes a heater which provides uniformity at the surface of a fuser roll that contacts an imaged sheet. The heater is configured to include a common tap at the center of a single heating trace. This allows for the benefits of a single trace configuration well while simultaneously providing a dedicated common line that does not have to be switched around.

  • Publication number: 20120051807
    Abstract: An improved fuser includes a heater which provides uniformity at the surface of a fuser roll that contacts an imaged sheet. The heater is configured to include a single resistive element shaped to heat multiple sheet sizes with independently controllable conductive traces connected to outer segments of the resistive element and adapted to supply electricity to separate sections of the resistive element in accordance with the size of sheet being fed through the fuser center registered and without the need for cold spot compensation.

  • Patent number: 8121528
    Abstract: Apparatuses useful for printing and methods of treating marking material on media are provided. An exemplary embodiment of the apparatuses useful for printing includes a roll including a first outer surface; a continuous belt including an inner surface and a second outer surface forming a nip by contact with the first outer surface, the belt being driven to rotate by rotation of the roll; a heater disposed inside of the belt and comprising a first heating surface contacting the inner surface of the belt at the nip; and a heating fin in thermal contact with the heater, the heating fin including a second heating surface extending circumferentially in contact with a pre-nip portion of the inner surface of the belt. Thermal energy is conducted from the heater to the heating fin. The second heating surface pre-heats the pre-nip portion of the belt before the pre-nip portion is rotated to the nip, and the first heating surface of the heater heats the pre-heated, pre-nip portion at the nip.

  • Patent number: 7587162
    Abstract: An improved fuser includes a heater that enhances uniform heating by altering the localized resistance which alters the localized power output of a resistive trace at the point of contact with a conductor trace in order to provide extra heating and thereby compensate for heat loss at the resistive trace/conductor trace junction.
