Final Project Presentation

Animated characters are solid modeled assemblies that can be 3D printed to show
motion of the character through mechanical means.
• Disney started working on animated characters in 2010
• Motion path software that created by disney
• Characters usually driven by motors or hand cranks
Motivation: Gain insight into the emerging fields of rapid prototyping, solidworks
animation, and parameterization of parts
Objective: Create an animated hamster using solidworks that captures its motion while
running, to be rapid prototyped by 3D printing.
Introduction
• Simple enough to use RP
• Single axle controls the movement of entire system
• Handle strong enough to carry wheel
• Rotation of wheel and motion of hamster happen simultaneously
• contact ratio of the gears be at least 1.4
Requirements
Design Strategy
• Design for
• 3 design concepts produced.
• 1 chosen due to simplicity and semester timeline/resources.
• Hamster was assumed to be designed later (subassembly).
• There are too many variables to effectively define with intent.
• Dynamic relationships not ideal to derive in this application.
• Other animated characters were reviewed.
• Spur gears were chosen to transfer power due to their simplicity,
effectiveness, and printability.
Technical Approach
Major Challenges
• Minimum global clearance ≥ 0.02
• Spur gear contact ratio ≥ 1.4
• This prevented a satisfactory global clearance.
• Hamster wheel was not ideal to print given the time.
• Takes too long to print.
• Quick and effective correction was to buy a hamster wheel.

Hamster 2.35 in3 $8.18
Handle 2.7 in3 $9.40
Total 24.6 in3 $85.75
• No existing model to compare with
• Reduce gears inside hamster from 6 to 3
• Reduce number of teeth of the middle and last gear inside bracket
• Aesthetically pleasing for hamster
Design Improvement
Prototype
• This project is a success
• Meeting all requirement
• Technical approaches to solve major challenges
• Providing recommendation for future work and study
Justifications
• Top-Down assembly method very useful
• Drives heavily dependant geometries i.e. links between gears and feet
• 3 gears instead of 6 for the hamster subassembly
• This was later discovered as a possible solutions that could perhaps
result to a “better” design regarding simplicity.
• Gear contact ratio affects minimum global clearance
• Not as important however 1.4 was desired
• Printing disassembled parts increases the probability of a successful print
• Full disassembly not necessary
• Must always consider all possible configurations and methods in order to
adapt to project requirements and anomalies.
Lessons Learned
Working on this project gave us experience into developing fields of engineering
that will help us grow in our career.
• The part costs $85.75 to print
• Simulation was used to find min handle size of ½ inch
• Insight into animated characters motion paths
Future Works
• Create fully 3D printed model
• Update tolerances to make model able to print as one piece
• Update hamster model to look aesthetically pleasing
