Is a 3d printer nozzle patented?

Short answer: specific designs of a 3d printer nozzle have been patented many times, but "a 3d printer nozzle" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What our index shows
  • 4,143 US and WO patent publications since 2000 have a title matching “d print” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 240 best keyword matches we examined, 159 were published in 2020 or later, and the earliest was published in 2006.
  • Most frequent assignees in those matches: XYZPRINTING INC (10), SHENZHEN CREALITY 3D TECH CO LTD (9), BOSCH GMBH ROBERT (9), STRATASYS INC (6).
  • Most common patent classes (CPC subclasses): B33Y (222), B29C (205), B22F (36), B29K (31).

Counts come from keyword matching on titles and abstracts, so they are indicative, not a legal count. Some matches are different products that share a word.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a 3d printer nozzle been patented?” but “has my combination of features been described before?” Consumer electronics are among the most heavily patented areas; the specific circuit, mounting, or interaction is what distinguishes a design.
