Such techniques can affect the quality of adhesion between adjacent layers of material, creating parts prone to separation and peeling
Conversely, if the cure of the supplied material is too small, parts prone to deformation and other undesirable properties may form

Abstract

The invention discloses a system and method for the cure control of additive manufacturing, and the system for cure control of additive manufacturing comprise a build volume, a curing energy source, and a controller. The curing energy source is configured to actively deliver curing energy to discrete sections of a part as it is being additively manufactured. The controller is programmed to directdelivery of curing energy to impart desired cure properties to the discrete sections and / or according to predetermined cure profiles for the discrete sections. Methods of additively manufacturing a part comprise additively building a part from a feedstock material, and actively curing discrete sections of the part as it is being additively built to impart desired cure properties to the part and / ordesired cure profiles to the part.

Description

technical field [0001] The present disclosure relates to additive manufacturing. Background technique [0002] Current additive manufacturing techniques using curable feedstocks, such as photopolymers, typically provide complete curing of the material while depositing the material through a nozzle (eg, by directing a light source directly at the outlet of the nozzle). Such techniques can affect the quality of adhesion between adjacent layers of material, creating parts prone to separation and peeling. Conversely, if the curing of the provided material is too small, parts prone to deformation and other undesirable properties may form. Contents of the invention [0003] The disclosed system for curing control in additive manufacturing includes: a build volume within which a part is additively manufactured; a curing energy source positioned relative to the build volume and configured to be additively manufactured during while actively delivering curing energy to discrete se...
