Appl. No.:

16/796122

Inventors:

- Brooklyn NY, US
Robert J. Steiner - Brooklyn NY, US
Aric Lynn Jennings - Brooklyn NY, US
William B. Buel - Sunnyvale CA, US
Anthony D. Moschella - Brooklyn NY, US

International Classification:

B29C 64/205
B33Y 50/02

B29C 48/92
B29C 64/209

Abstract:

A supply of build material such as a spool or cartridge is instrumented with a data tag that includes information about the build material. A three-dimensional printer, or a tag reader in communication therewith (directly or indirectly), can read the information from the tag for a determination as to how to use the build material during fabrication of a three-dimensional object.

Abstract:

A three-dimensional scanner uses a rotatable mounting structure to secure a laser line source in a manner that permits rotation of a projected laser line about an axis of the laser, along with movement of the laser through an arc in order to conveniently position and orient the resulting laser line. Where the laser scanner uses a turntable or the like, a progressive calibration scheme may be employed with a calibration fixture to calibrate a camera, a turntable, and a laser for coordinated use as a three-dimensional scanner. Finally, parameters for a scan may be automatically created to control, e.g., laser intensity and camera exposure based on characteristics of a scan subject such as surface characteristics or color gradient.
