Abstract

Described herein are systems, methods, and apparatus that allow a user to convert various styles of three dimensional graphic representations of molecular models to computer aided design format to enable printing of a physical model using three dimensional printing equipment such as rapid prototyping equipment, additive manufacturing equipment, and/or three dimensional printers.

Claims

1. A system for converting graphic representations of three dimensional molecular models into computer-aided design format, the system comprising:

a processor; and

a memory having a set of instructions stored thereon, wherein the instructions, when executed, cause the processor to;

receive, within a chemical structure rendering application, a request identifying a three dimensional model of a chemical and/or biological structure wherein the request is one of a file save request and a print request,

associate the request with conversion to a computer-aided design format,

access the three dimensional model,

identify a surface region of a graphic representation of the three dimensional model,

convert the surface region into a polygon mesh representation, and

validate the polygon mesh representation, wherein validating the polygon mesh representation comprises analyzing the polygon mesh representation to identify any inner vertices and/or mesh openings that fail to represent a single watertight wrapped surface of the polygon mesh representation of the three dimensional model.

2. The system of claim 1, wherein the instructions cause the processor to, after converting the surface region into the polygon mesh representation:

remove one or more of the inner vertices identified by the processor.

3. The system of claim 1, wherein the instructions cause the processor to adjust the polygon mesh representation to close one or more openings.

4. The system of claim 1, wherein the instructions cause the processor to identify one or more unprintable features of the graphic representation.

5. The system of claim 4, wherein the instructions cause the processor to identify a type of three dimensional printing equipment, wherein identifying the one or more unprintable features comprises identifying, based upon printer capabilities associated with the type of the three dimensional printing equipment, at least one of the one or more unprintable features.

6. The system of claim 4, wherein the instructions cause the processor to, after identifying the one or more unprintable features, cause presentation of a prompt within a user interface of the application, prompting modification of one or more feature settings of the three dimensional model to convert the graphic representation to a printable graphic representation having printable features.

7. The system of claim 6, wherein the instructions cause the processor to:

receive an acknowledgement of authorization; and

automatically adjust the one or more feature settings.

8. The system of claim 1, wherein the instructions cause the processor to verify the graphic representation comprises a self-supporting structure.

9. The system of claim 1, wherein the polygon mesh representation comprises a triangular mesh.

10. The system of claim 1, wherein the instructions cause the processor to, after converting the surface region into the polygon mesh representation, save the polygon mesh representation as a computer aided design file.

11. The system of claim 10, wherein the computer aided design file is in STL file format.

12. The system of claim 1, wherein the instructions cause the processor to, after converting the surface region into the polygon mesh representation, issue print instructions comprising the polygon mesh representation to a three dimensional printing equipment.

13. The system of claim 12, wherein the three dimensional printing equipment is one of rapid prototyping equipment, additive manufacturing equipment, and a three dimensional printer.

14. The system of claim 1, wherein the three dimensional model is one of a ribbon protein model, a space filling model, a cartoon model, and a ball and stick model.

15. The system of claim 1, wherein the chemical structure rendering application is one of an electronic notebook application and a chemistry modeling application.

16. The system of claim 1, wherein the three dimensional model comprises one or more of an XML file and a PDB file.

17. The system of claim 1, wherein the three dimensional model comprises a .c3xml file.

18. A method comprising:

receiving, by a processor of a computing device, within a chemical structure rendering application, a request identifying a three dimensional model of a chemical and/or biological structure, wherein the request is one of a file save request and a print request;

associating, by the processor, the request with conversion to a computer-aided design format;

accessing, by the processor, the three dimensional model;

identifying, by the processor, a surface region of a graphic representation of the three dimensional model;

converting, by the processor, the surface region into a polygon mesh representation; and

validating, by the processor, the polygon mesh representation, wherein validating the polygon mesh representation comprises analyzing the polygon mesh representation to identify any inner vertices and/or mesh openings that fail to represent a single watertight wrapped surface of the polygon mesh representation of the three dimensional model.

19. The method of claim 18, further comprising printing, by a three dimensional printer, the three dimensional model using the polygon mesh representation.

20. A non-transitory computer readable medium having instructions stored thereon, wherein the instructions, when executed by a processor, cause the processor to:

receive, within a chemical structure rendering application, a request identifying a three dimensional model of a chemical and/or biological structure, wherein the request is one of a file save request and a print request;

associate the request with conversion to a computer-aided design format;

access the three dimensional model;

identify a surface region of a graphic representation of the three dimensional model;

convert the surface region into a polygon mesh representation; and

validate the polygon mesh representation, wherein validating the polygon mesh representation comprises analyzing the polygon mesh representation to identify any inner vertices and/or mesh openings that fail to represent a single watertight wrapped surface of the polygon mesh representation of the three dimensional model.

21. The computer readable medium of claim 20, wherein the instructions, when executed by the processor, cause the processor to print, by a three dimensional printer, the three dimensional model using the polygon mesh representation.

22. A system for converting graphic representations of three dimensional molecular models into computer-aided design format, the system comprising:

a processor; and

a memory having a set of instructions stored thereon, wherein the instructions, when executed, cause the processor to;

receive, within a chemical structure rendering application, a request identifying a three dimensional model of a chemical and/or biological structure, wherein the request is one of a file save request and a print request,

associate the request with conversion to a computer-aided design format,

access the three dimensional model,

identify a surface region of a graphic representation of the three dimensional model,

convert the surface region into a polygon mesh representation,

identify one or more unprintable features of the graphic representation, and

cause presentation of a prompt within a user interface of the application, prompting modification of one or more feature settings of the three dimensional model to convert the graphic representation to a printable graphic representation having printable features.
