Abstract
Compositions for reactive additive manufacturing using recycled components obtained from previously manufactured articles produced by additive manufacturing, as well as methods of making and using the compositions. The compositions may include a first reactive component and a second reactive component, the first and second reactive components reactive with each other, together with particles comprising a recycled, cured thermoset component, the particles present in an amount greater than 2 wt. % based on total weight of the composition, and a filler present in an amount from 1 to 10 wt. % based on a total weight of the composition.
Claims20
A composition for reactive additive manufacturing, comprising:
- a first reactive component;
- a second reactive component, the first and second reactive components reactive with each other;
- particles comprising a cured thermoset component, the particles present in an amount greater than 2 wt. % based on a total weight of the composition;
- and
- a filler present in an amount of from 1 to 10 wt. % based on the total weight of the composition.
A method of forming an object with a reactive additive manufacturing composition, comprising:
- combining a first reactive component, a second reactive component, and particles comprising a reaction product of a cured thermo-set component, the cured thermoset component particles present in an amount of at least 2 wt. % based on a total weight of the composition;
- mixing the first reactive component, second reactive component, and the cured thermoset component particles;
- and
- sequentially depositing the composition in a plurality of layers to form a three-dimensional object.
