One kinematic couple couples the bed to the support truss and a second kinematic couple couples the support truss to a frame of the printer. Both kinematic couples ensure that a common geometric center along each kinematic couple is maintained despite thermal expansion of the printer bed and the support truss occurring at different rates. The kinematic coupling system mitigates deformations to 3D-printed items from the effects of thermal expansion.Type: ApplicationFiled: February 21, 2024Publication date: August 29, 2024Inventors: Ron Tozier, Kyra Rubinstein, Ryan Binter

Publication number: 20240286353Abstract: According to some aspects, an additive fabrication device and a build platform suitable for use within an additive fabrication device are provided. The build platform may include a build surface on which material may be formed by the additive fabrication device when the build platform is installed within the additive fabrication device. According to some embodiments, the build platform may include a flexible build layer and at least one removal mechanism configured to be actuated to apply a force to the flexible build layer. Such actuation may cause the flexible build layer to deform, thereby enabling separation of material adhered to the build surface from the build platform. According to some embodiments, the build platform may comprise a restorative mechanism that acts to return the flexible build layer to a flat state so that subsequent additive fabrication may form material on a flat build surface.Type: ApplicationFiled: March 4, 2024Publication date: August 29, 2024Applicant: Formlabs, Inc.Inventors: Craig Broady, Gurshan Deol, Gagandeep Singh

Publication number: 20240286355Abstract: Techniques for improved efficiency of sintering in additive fabrication are described. According to some aspects, mechanisms for depositing and leveling source material are combined with a mechanism for heating the material. In some embodiments, one or more heating elements may be arranged to lead and/or follow a material deposition mechanism such that heat may be applied to the build region in concert with deposition of material. As a result of this technique, the heating and depositing steps may be performed closer together in time and/or heat may be applied more directly to the material than in conventional systems. As a result, greater control over material temperature may be achieved, thereby avoiding excess temperature exposure and subsequent undesirable changes to the material.Type: ApplicationFiled: March 6, 2024Publication date: August 29, 2024Applicant: Formlabs, IncInventors: Eduardo Torrealba, Steven Thomas, Christopher Auld

Publication number: 20240286356Abstract: 3D printers perform additive manufacturing by depositing heated material (commonly plastic) onto a surface from a printer nozzle. During a 3D print, nozzles may “ooze” excess material, leading to deformities in 3D prints. Disclosed is an anti-ooze mechanism that covers up 3D printer nozzles when they are not being used. A servo moves a nozzle shield in front of and away from a nozzle while a 3D print is happening so that no ooze drips onto a 3D print or otherwise escapes from a printer nozzle onto the printer bed. Moreover, the servo can move the nozzle shield quickly to minimize the amount of time that a nozzle spends uncovered, and the nozzle shield is also capable of “scraping off” excess material from the nozzle head.Type: ApplicationFiled: February 21, 2024Publication date: August 29, 2024Inventors: Ron Tozier, Kyra Rubinstein, Ryan Binter

Publication number: 20240286357Abstract: Methods and systems for manufacturing a part with a random decorative pattern are described. In some embodiments, a part may be manufactured by obtaining a three-dimensional model of the part, generating a random decorative patter using a random pattern generator, and then modifying the three-dimensional model based on the random decorative pattern. A build plan may be then generated for use by a manufacturing system to manufacturing the part using any appropriate type of manufacturing process.Type: ApplicationFiled: May 12, 2023Publication date: August 29, 2024Applicant: ASSA ABLOY Residential Group, Inc.Inventors: Ping Hsien Tsai, William Carl Zhang

Publication number: 20240286358Abstract: A system for three-dimensional printing comprises: a three-dimensional printing apparatus for printing an object using a building material supplied from a container, and a computer. The computer is configured to receive working hours of personnel operating the apparatus, to calculate, based on three-dimensional printing data describing the object, a supply period during which the container is expected to be emptied, and to transmit to the apparatus a signal to initiate the printing at a delayed time selected to ensure that an end time of the supply period is within the working hours.Type: ApplicationFiled: June 15, 2022Publication date: August 29, 2024Applicant: Stratasys Ltd.Inventors: Shmuel RUBIN, Kiril LAIN, Dan MORDECHAY, Barak GLASSMAN, Eliyahu TSUBERY

Publication number: 20240286359Abstract: A system and method is provided to construct a structure using three dimensional printing of extrudable building material to a wall surface of a structure. According to one embodiment, a printing assembly is moveably disposed above the surface, and extrudable building material is applied from a nozzle onto the surface. One or more profilometers measure at periodic intervals along a geometric cross-section of a bead of extrudable building material. One or more controllers compare the measured cross-section to a predetermined, target cross section and one or more controllers periodically change, for example, the rate of application and/or the viscosity of the extrudable building material applied along the longitudinal axis. The nozzle direction can change, and the profilometers can be rotated about the nozzle along different longitudinal axes, or directions, depending on the wall locations being formed.Type: ApplicationFiled: January 27, 2024Publication date: August 29, 2024Applicant: ICON Technology, IncInventors: Walelign Messele Nikshi, Brannon Veal
