1. A print head assembly for additive manufacturing, comprising:
- a print head configured to deposit a plurality of layers during the production of an additively manufactured article; and
a reinforcement head configured to form at least one reinforcement element on or within a working layer of said plurality of layers;
wherein;
said at least one reinforcement element comprises a reinforcement structure;
said reinforcement head comprises;
a housing comprising an opening; and
a biasing member;
the biasing member is movable between a retracted position and an extended position;
in the retracted position the biasing member is disposed within said housing; and
in the extended position at least a portion of the biasing member extends out of the opening and is at least partially inserted into the working layer to form said at least one reinforcement element.

Abstract
Reinforcement systems for additive manufacturing are disclosed. In some embodiments, the reinforcement systems include a print head assembly including a print head that is configured to form a plurality of layers of an additively manufactured article, and a reinforcement head. The reinforcement head may be configured to form at least one reinforcement element on or within a working layer of the plurality of layers formed by the print head. Additive manufacturing systems including such reinforcement systems and methods of additive manufacturing using those reinforcement systems are also disclosed.

15. A print head assembly for additive manufacturing, comprising:
-
a print head configured to deposit a plurality of layers during the production of an additively manufactured article; and a reinforcement head configured to form at least one reinforcement element on or within a working layer of said plurality of layers; wherein; said at least one reinforcement element comprises at least one discrete reinforcing article; said reinforcement head comprises; a housing comprising an opening; and an install member within the housing, the install member comprising an install surface proximate to said opening; the install member is movable between upper and lower positions within said housing; the install member is configured such that when it is moved from said upper position to said lower position, said install surface contacts said at least one discrete reinforcing article to drive the at least one discrete reinforcing article out of said opening, such that at least a portion of the at least one discrete reinforcing article is embedded into a surface of the working layer. - View Dependent Claims (16)
