Abstract
The invention relates to apparatus and methods for producing three-dimensional objects and auxiliary systems used in conjunction with the aforementioned apparatus and methods. The apparatus and methods involve 3D printing and servicing of the equipment used in the associated 3D printer.
Claims13
A method of creating a test pattern with a plurality of printheads of a three-dimensional printer, the method comprising:
- defining an area on a build surface for receiving the test pattern;
- selecting a reference printhead capable of printing with a high contrast;
- printing a reference line with the reference printhead;
- and
- printing a test line proximate to the reference line with at least one of the remaining printheads.
2 more elements
A test pattern for aligning a plurality of printheads in a three-dimensional printer, the test pattern comprising:
- a plurality of substantially evenly spaced solid reference lines;
- and
- a plurality of test lines disposed in an alternating pattern with the plurality of reference lines, wherein each of the test lines comprises at least one bar of a non-reference color.
