Techniques for producing a flat film surface in additive fabrication and related systems and methods
Patent number: 11878467Abstract: Techniques for producing a flat film surface in additive fabrication are provided. According to some aspects, a movable stage may be arranged beneath a container having a base that includes a flexible film. The movable stage may include a segmented member in which a number of segments are aligned along a common axis. The segmented member may maintain contact with the flexible film as the movable stage moves beneath the container, with the segmented member producing a flat surface of the flexible film, at least within a region above the movable stage. According to some embodiments, multiple segmented members may be provided within the movable stage, such as in parallel with one another.Type: GrantFiled: May 31, 2019Date of Patent: January 23, 2024Assignee: Formlabs, Inc.Inventors: Shane Wighton, Maxim Lobovsky, Robert Joachim, Jack Moldave, Adam Damiano, Christian Reed, Dmitri Megretski, Benjamin FrantzDale -

Publication number: 20230078198Abstract: Techniques for force sensing in additive fabrication are provided. According to some aspects, an additive fabrication device may include a force sensor configured to measure a force applied to a build platform during fabrication. A length of time taken for a layer of material to separate from a surface other than the build platform to which it is adhered may be determined based on measurements from the force sensor. Subsequent additive fabrication operations, such as subsequent motion of the build platform, may be adapted based on the determined length of time.Type: ApplicationFiled: July 18, 2022Publication date: March 16, 2023Applicant: Formlabs, Inc.Inventors: Maxim Lobovsky, Shane Wighton, Dmitri Megretski, Adam Damiano

Publication number: 20220362998Abstract: According to some aspects, an additive fabrication apparatus is provided configured to form layers of material on a build platform, each layer of material being formed so as to contact a supporting liquid or a film disposed within a container, in addition to the build platform, a liquid photopolymer, and/or a previously formed layer of a material. The additive fabrication apparatus may comprise a container and a leveling element, wherein the leveling element is configured to move across a liquid-liquid interface to promote or create a flat interface between the two liquids. According to some aspects, the additive fabrication comprises a film disposed between two liquids, wherein the film maintains or provides a flat surface at the interface of the two liquids.Type: ApplicationFiled: March 31, 2022Publication date: November 17, 2022Applicant: Formlabs, Inc.Inventors: Adam Damiano, Dmitri Megretski, Shane Wighton, Maxim Lobovsky

Patent number: 11167491Abstract: Multi-film containers for use in additive fabrication devices are provided. According to some aspects, a container may include multiple films that are at least partially detached from one another. In some embodiments, the multiple films may include films formed from different materials. As one example, an upper film may be formed so as to be relatively impermeable to substances within a source material of an additive fabrication device, whereas a lower film may be formed so as to provide desirable mechanical properties. In some cases, the multiple films may be commonly tensioned while being unattached to one another.Type: GrantFiled: May 31, 2019Date of Patent: November 9, 2021Assignee: Formlabs, Inc.Inventors: Benjamin FrantzDale, Konstantinos Oikonomopoulos, Shane Wighton, Dmitri Megretski, Adam Damiano, James Loomis, Christian Reed

Patent number: 9515832Abstract: The techniques and systems described herein present various implementations of a model for authenticating processes for execution and specifying and enforcing permission restrictions on system resources for processes and users. In some implementations, a binary file for an application, program, or process may be augmented to include a digital signature encrypted with a key such that an operating system may subsequently authenticate the digital signature. Once the binary file has been authenticated, the operating system may create a process and tag the process with metadata indicating the type of permissions that are allowed for the process. The metadata may correspond to a particular access level for specifying resource permissions.Type: GrantFiled: June 24, 2013Date of Patent: December 6, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Vishal Agarwal, Sunil P.
