Abstract
Compositions or finishing solutions configured to remove unwanted material, such as uncured material or resin, from additively manufactured objects are disclosed herein, in one example, the finishing solution includes a first glycol ether and a second glycol ether and/or a high flash point hydrocarbon, wherein the finishing solution has a flash point of at least 93.3° C. In alternative examples, the finishing solution may also include a third glycol ether, a high flash point alcohol, and/or an acetate of a glycol ether.

A finishing solution configured to remove unwanted material from a surface of an object, the finishing solution comprising:
- a first glycol ether;
- and
- a second glycol ether and/or a high flash point hydrocarbon,
- wherein the finishing solution has a flash point of at least 93.3° C.

A method of removing unwanted material from a surface of an object, the method comprising:
- providing a finishing solution having a first glycol ether and a second glycol ether and/or a high flash point hydrocarbon, wherein the finishing solution has a flash point of at least 93.3° C.;
- submerging the object in the finishing solution;
- agitating the object while the object is submerged in the finishing solution;
- and
- removing the object from the finishing solution, wherein unwanted material has been removed from the surface of the object and remains within the finishing solution.

A partially-cured and cleaned object with unwanted material removed from a surface of the partially-cured and cleaned object, wherein the partially-cured and cleaned object is formed by a process of:
- providing a finishing solution having a first glycol ether and a second glycol ether and/or a high flash point hydrocarbon, wherein the finishing solution has a flash point of at least 93.3° C.;
- submerging, in the finishing solution, a partially-cured object having the unwanted material on the surface of the partially-cured object;
- agitating the partially-cured object while the partially-cured object is submerged in the finishing solution;
- and
- removing the partially-cured object from the finishing solution, wherein the unwanted material has been removed from the surface of the partially-cured object and remains within the finishing solution, therein forming the partially-cured and cleaned object,
- wherein the partially-cured object is a three-dimensional (3D) printed object, and
- wherein the unwanted material comprises uncured resin on the surface of the 3D printed object.
