Abstract

An article of manufacture includes a three-dimensional (3D) printed object for chemical reaction control. The 3D printed object includes a chemical reactant to be released to control a chemical reaction according to a chemical reactant release profile. The chemical reactant release profile is determined based on a shape of the 3D printed object.

First claim

What is claimed is:

1. A process of forming a three-dimensional (3D) printed object for chemical reaction control, the process comprising:
determining, by a processor, for a chemical reaction to be performed according to a specific set of reaction parameters, a chemical reactant release profile for one or more chemical reactants to be released to control the chemical reaction, wherein the chemical reactant release profile indicates a concentration level of each of the one or more chemical reactants;
determining a shape of a three-dimensional (3D) object to release the one or more chemical reactants according to the chemical reactant release profile, wherein the shape of the 3D object includes one or more arms, each of the one or more arms being at least one of the one or more chemical reactants;
generating chemical reactant 3D printing instructions corresponding to the shape of the 3D object; and
utilizing a 3D printer to form a 3D printed object according to the chemical reactant 3D printing instructions, the 3D printed object including the one or more chemical reactants to be released to control the chemical reaction according to the chemical reactant release profile.

2. The process of claim 1 , wherein the chemical reaction includes a cross-coupling polymerization reaction, a substitution nucleophilic (SN2) reaction, a Grignard reaction, a living anionic polymerization reaction, a living cationic polymerization reaction, a living ring-opening metathesis polymerization reaction, a living free radical polymerization reaction, or a living chain-growth polycondensation reaction.

3. The process of claim 1 , further comprising utilizing the 3D printer to encapsulate the 3D printed object in an encapsulating material.

4. A computer-implemented method comprising:
determining, by a processor, for a chemical reaction to be performed according to a specific set of reaction parameters, a chemical reactant release profile for one or more chemical reactants to be released to control the chemical reaction, wherein the chemical reactant release profile indicates a concentration level of each of the one or more chemical reactants;
determining a shape of a three-dimensional (3D) object to release the one or more chemical reactants according to the chemical reactant release profile, wherein the shape of the 3D object includes one or more arms, each of the one or more arms being at least one of the one or more chemical reactants;
generating chemical reactant 3D printing instructions corresponding to the shape of the 3D object, the chemical reactant 3D printing instructions to be utilized to form a 3D printed object that includes the one or more chemical reactants to be released to control the chemical reaction according to the chemical reactant release profile; and
utilizing a 3D printer to form the 3D printed object according to the chemical reactant 3D printing instructions, wherein the 3D printer includes a 6-axis 3D printer.

5. The computer-implemented method of claim 4 , further comprising storing the chemical reactant 3D printing instructions at a computer-readable storage device of a first entity, the stored chemical reactant 3D printing instructions to be utilized by a second entity to form the 3D printed object using a 3D printer.

6. The computer-implemented method of claim 5 , wherein the first entity performs the chemical reaction according to the specific set of reaction parameters, and wherein the stored chemical reactant 3D printing instructions are utilized by the second entity to reproduce the chemical reaction according to the specific set of reaction parameters.

7. The computer-implemented method of claim 5 , wherein the chemical reactant 3D printing instructions are stored at the computer-readable storage device in an object (.obj) file format.
