Introduction
Interpreting dimensioned drawings is an important engineering skill. Using drawings to create a computer model of a part or product is also important. Communicating information effectively allows a group of people to function as a design team.
In this project you will further develop your modeling skills and your ability to use a computer as an efficient communication tool. The skills that you learned earlier in this course will be systematically applied to model and fabricate a 3D object.
Concepts
- Researching the pros and cons of 3D printing
- Understanding that technical drawings convey information according to an established set of drawing practices which allow for detailed and universal interpretation of the drawing
- Advanced modeling features, as a way of creating three-dimensional solid models of complex parts and assemblies within CAD, using appropriate geometric and dimensional constraints
- Collaboration with fabricators
Procedure
- Research:
How long will it take to have your part printed? What will it cost? Where will it be coming from? What specifications will you need to share with them? Research the 3D printing process. Determine which facility/fabricator will best serve your needs -- specifically, the size and weight specifications that meet expected cost.
- Sketch:
What part would you like to see fabricated? What constraints will you need to work within? Create multiview sketches of your part in your engineering notebook.
- CAD:
How will you transform your 2D sketch into a 3D model? Model your sketches in Inventor.
- Fabricate:
Share your .STL files with a fabricator, and document your fabricated object.
Deliverables
- Research notes on the pros and cons of 3D printing
- Multiview sketches of your object
- Assembly file of your parts
- .STL file of your object
- Fabricated object made by someone else
Conclusion
Complete a reflection for the following topics as they relate to your own work. Provide facts and evidence to support your opinions.
- What do you think of when you see something that comes from a machine? How is it different when it’s made by a human?
- Are working drawings always necessary in order to communicate the design of a consumer product? Justify your answer.
- Animated assemblies are not typically included as part of the technical documentation of a design. How can 3D animated assembly models of an object or a proposed design be used in the design process? Beyond the design process?
