Publication number: 20200142384Abstract: Methods and systems are provided, which convert points in a cloud into a model for 3D printing in a computationally efficient manner and while maintaining and possibly adjusting shape, volume and color information. Methods include deriving, from the points, a crude watertight mesh with respect to the points, e.g., an alpha shape, determining, using normal vectors associated with the points, locations of the points with respect to the mesh (e.g., as being inside, outside or within the model) and using the derived mesh to define the model with respect to the determined locations of the points. Combining the computational geometry approach with the field approach is synergetic and results in better information content of the resulting model for 3D printing while consuming less computational resources.Type: ApplicationFiled: July 12, 2018Publication date: May 7, 2020Applicant: STRATASYS LTD.Inventor: Yoav BRESSLER

Patent number: 10427354Abstract: Some embodiments of the invention may be related to a system and method of printing a three-dimensional (3D) object and a support construction for the 3D object. The system may include a printing unit and a supply system for supplying a body material and a support material to the printing unit. The system may further include a controller be configured to: generate 3D cross sectional digital data comprising a set of horizontal slices, to manipulate the 3D digital data to create a set of shifted slices by performing vertical shifts between body regions and support regions of a same horizontal slice to create printing digital data and to control the printing unit to deposit, in layers, the body material and the support material based on the printing digital data, wherein in a single scan, droplets of the support material and droplets of the body material travel different distances.Type: GrantFiled: June 7, 2016Date of Patent: October 1, 2019Assignee: STRATASYS LTD.Inventors: Daniel Dikovsky, Eduardo Napadensky, Shai Hirsch, Evgeni Levin, Yoav Bressler

Patent number: 9550901Abstract: An inkjet printing method includes providing an inkjet composition, which includes a radiation curable monomer or oligomer, a photo-initiator, and an inhibitor present in an amount sufficient to prevent full curing of the radiation curable monomer or oligomer during an initial exposure to a curing energy. First drops of the inkjet composition are deposited onto a substrate. The curing energy is selected such that it is sufficient to substantially consume the inhibitor. The first drops are exposed to the curing energy, whereby the first drops retain substantially a same surface tension as a liquid drop of the inkjet composition. Second drops of the inkjet composition are deposited adjacent to the first drops. The first and second drops are exposed to the curing energy, whereby the first drops are at least partially cured and the second drops retain substantially the same surface tension as a liquid drop of the inkjet composition.Type: GrantFiled: May 28, 2014Date of Patent: January 24, 2017Assignee: Hewlett-Packard Industrial Printing LTD.Inventors: Alex Trubnikov, Lior Lifshitz, Yoav Bressler, Eytan Cohen, Danny Seidner
