Patent number: 11850797Abstract: A liquefier tube for an additive manufacturing system, the liquefier tube including a body provided with a feed channel including a feeding portion having a first diameter, an outlet portion having a second diameter, the first diameter being larger than the second diameter, a transitional portion interconnecting the feeding portion and the outlet portion. The transitional portion has a monotonically decreasing third diameter from the feeding portion to the outlet portion and the third diameter as function of a longitudinal position of the feed channel in the transitional portion between the feeding portion and the outlet portion and at a transition between the transitional portion and the outlet portion is differentiable. Methods of manufacturing the liquefier tube.Type: GrantFiled: October 2, 2019Date of Patent: December 26, 2023Assignee: BOND HIGH PERFORMANCE 3D TECHNOLOGY B.V.Inventors: Adrianus Bruggeman, Marald Speelman, Klaas Groen, Martijn Johannes Wolbers, Koendert Hendrik Kuit, Antonie Everhard Ekkelenkamp

Patent number: 11207832Abstract: A printhead assembly having connection for connecting to a positioning system of an AM system, a feedstock liquefying unit having a nozzle for depositing liquefied AM feedstock onto at least one of a build plate and an object to be created. The feedstock liquefying unit has a supply opening and a supply channel from the supply opening to the nozzle. The printhead assembly has heat exchanging elements attached to the printhead assembly, arranged to establish a releasable clamping connection with the feedstock liquefying unit to accommodate the feedstock liquefying unit in the printhead assembly. The heat exchanging elements are actuatable to an open state, and a closed state. A system for additive manufacturing, including a build plate, a positioning system associated with at least one of the printhead assembly and the build plate, a feedstock liquefying unit storage, a controller arranged for controlling the positioning system for replacing the feedstock liquefying unit.Type: GrantFiled: December 20, 2018Date of Patent: December 28, 2021Assignee: BOND HIGH PERFORMANCE 3D TECHNOLOGY B.V.Inventors: Thomas Jonathan Bruggeman, Adrianus Bruggeman, Kevin Hendrik Jozef Voss, Marald Speelman, Klaas Groen, Johannes Hermannus Timmer Arends, Martijn Johannes Wolbers, Koendert Hendrik Kuit

Patent number: 11046012Abstract: A method for generating a signal indicative for nozzle maintenance, including feeding modeling material through a feed channel of a printhead to a nozzle of the printhead in a three-dimensional modeling system, determining a parameter indicative of a fluid resistance of modeling material within the nozzle. Determining the parameter includes determining a flowrate of the modeling material within the feed channel, determining a pressure exerted on the modeling material within the feed channel and determining a pressure exerted on the modeling material outside the feed channel, determining a pressure difference between the pressure exerted on the modeling material within the feed channel and the pressure exerted on the modeling material outside the feed channel, and calculating the parameter from the determined flow rate and the determined pressure difference.Type: GrantFiled: April 16, 2018Date of Patent: June 29, 2021Assignee: BOND HIGH PERFORMANCE 3D TECHNOLOGY B.V.Inventors: Thomas Jonathan Bruggeman, Adrianus Bruggeman, Martijn Johannes Wolbers, Kevin Hendrik Jozef Voss, Bouwe Kuiper, Koendert Hendrik Kuit, Marald Speelman
