Articles including a coupling to engage a tool, kits, additive manufacturing methods of making same, and methods of computing models of the articles

A method of making an additive manufactured article, the method comprising:

• a) obtaining a photopolymerizable material;
• b) selectively curing the photopolymerizable material to form an additive manufactured article comprising a first portion and a second portion integral to the first portion, wherein the second portion comprises a coupling configured to engage a tool, and wherein the second portion comprises a frangible section at a connection point to the first portion.

A kit comprising:

• a) an additive manufactured article comprising a first portion and a second portion integral to the first portion, wherein the second portion comprises a coupling configured to engage a tool, and wherein the second portion comprises a frangible section at a connection point to the first portion;
• and
• b) a tool configured to attach to the coupling.

A non-transitory machine readable medium comprising data representing a three-dimensional model of an article, when accessed by one or more processors interfacing with a 3D printer, causes the 3D printer to create an additive manufactured article comprising a first portion and a second portion integral to the first portion, wherein the second portion comprises a coupling configured to engage a tool, and wherein the second portion comprises a frangible section at a connection point to the first portion.

A method comprising:

• a) receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article;
• and
• b) generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object, the article comprising a first portion and a second portion integral to the first portion, wherein the second portion comprises a coupling configured to engage a tool, and wherein the second portion comprises a frangible section at a connection point to the first portion.

A system comprising:

• a) a display that displays a 3D model of an article;
• and
• one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of the article, the article comprising a first portion and a second portion integral to the first portion, wherein the second portion comprises a coupling configured to engage a tool, and wherein the second portion comprises a frangible section at a connection point to the first portion.
