Tigard High School will be creating 3D Printed RC boats that avoid obstacles in water starting in Spring 2018. You will soon find several different thingiverse designs from us.
You can create your own too! This design is the example boat for students to use as a baseline for their creations.
You will need to 3D print the Front and back of the boat and glue it together. The best glue for the job is epoxy.
Instructions and detail of project is available with the handout given.
Have fun and drive your boat around in the water! (Video updates will be loaded soon).
Choose a low infill so the print isn't to heavy. It will not float well if it is heavy.
Overview and Background
Create an Moving 3D Print
Design and create an RC boat that will be put on Thingiverse for THS. You will be on a team of two creating boat. Several obstacles will lay in your way, including navigating the waters! The boats you will design and product will be available on Thingiverse for people to download and tip the THS program.
Lesson Plan and Activity
Teach students about the foundation of boats and buoyancy. Then it is time to design a boat!
DAY 1-3: Students will start in teams of two designing a boat. The first 2-3 class periods will be designing the boat. Students work in Fusion 360 or Inventor (any CAD program works)
DAY 4: Students will 3D print designs. Once the propeller is finished students can secure it to the motor and make a shroud while the boat finishes.
DAY 5: Students glue boat together with epoxy. In mean time, students can plug in and test RC components outside of boat.
DAY 6: Built boat and test. Bring in a kiddy pool or long tub.
DAY 7: Fix boat as needed.
DAY 8: Field test at a swimming pool or other location.
DAY 9: Fix boat as needed.
- DAY 10: Competition to collect given objects at stations.
- Problem Solving
- critical thinking
- 3d printing
- weight distribution
- team work
- Need a location for the boats to move around. A pool, lake, fountain.
- Need several 3D printers because these prints will run overnight.
Need to have epoxy and hot glue gun handy.
- Several items that would need to go onto an Google classroom includes:
Fusion 360 designed motor, servo, battery. They have real world weight to them so that when the students use these items to design. They can calculate if their boat will sink or swim before 3D printing. Also, the pdf & drawing of the propeller will need to go into the assignment.
