Method And System For Rendering Data For Addressable Dispensing

View page
US Patent:
20200346411, Nov 5, 2020
Filed:
Aug 27, 2018
Appl. No.:
16/642900
Inventors:
- Rehovot, IL
Ore SHTALRID - Yavne, IL
Yossi KOREN - Jerusalem, IL
Blake Zachary COURTER - Reading MA, US
Stephen DEMAI - Cambridge MA, US
Assignee:
Stratasys Ltd. - Rehovot
International Classification:
B29C 64/393
B33Y 10/00
B33Y 30/00
B29C 64/112
B33Y 50/02
Abstract:
A method of rendering data for addressable dispensing of material over a working surface, comprises: receiving input image data arranged grid-wise over a plurality of picture-elements; generating an initial map describing a distance field and having a plurality of map-elements each storing distance information corresponding to one picture-element; for each picture-element of at least a portion of the picture-elements: linearly scanning the map independently along a first axis and along a second axis, and updating a respective map-element based on values of map-elements visited during the scan. The distance field can include distances defined perpendicularly to the working surface.

US Patent:
20200035015, Jan 30, 2020
Filed:
Oct 6, 2019
Appl. No.:
16/594026
Inventors:
- Rehovot, IL
Stephen DEMAI - Cambridge MA, US
Assignee:
Stratasys Ltd. - Rehovot
International Classification:
G06T 15/08
B29C 64/393
B33Y 50/02
G06F 17/50
G06T 15/00
G06T 1/20
G06T 15/50
Abstract:
A system for generating slice data for additive manufacturing, comprises a graphics processing unit (GPU) that receives a digital model of an object in a three-dimensional build space defined over a plurality of slices, computes a three-dimensional signed distance field over voxels in the build space, assigns a building material to each voxel based on a respective distance field value, and generates slice data output pertaining to the building material assignments for each slice. The slice data output can be used for printing the object in layers corresponding to the slices. The distance field comprises one or more vector having a vertical component with respect to the slices.

US Patent:
20180240263, Aug 23, 2018
Filed:
Feb 24, 2017
Appl. No.:
15/517436
Inventors:
- Rehovot, IL
Stephen Demai - Cambridge MA, US
International Classification:
G06T 15/08
B29C 64/393
B33Y 50/02
G06T 15/50
G06T 15/00
G06T 1/20
G06F 17/50
Abstract:
A method includes selecting a voxel from a three-dimensional build space and for the selected voxel, determining a distance field value relative to a digital model of a 3D part in the three-dimensional build space. The distance field value is then used to select at least one material selection rule and a feature of the voxel is applied to the at least one material selection rule to identify a material designation for the voxel. The material designation indicates no material is to be placed at the voxel when the material selection rule identifies no material for the voxel and the material designation indicates at least one material is to be placed at the voxel when the at least one material selection rule identifies the at least one material for the voxel. The material designation for the voxel is then output for use in printing the 3D part using an additive manufacturing system.
