CUSTOMER REQUIREMENTS & PRODUCT SELECTION

• Kids from ages 5 to 10
• We chose a car because it’s a universally appealing toy, and we made it “built it

yourself" so kids are able to change out the body style and see the inner workings of a car

• Other ideas we had:

– “Angry Birds” real life simulation game – Brain teaser puzzle – Solar powered car

CONCEPTUAL DESIGN

• Several choices and different routes we could take building the car:

– 3D print the wheels vs. buy wheels – Solar power vs. propeller – 3D print body vs. build out of wood

• We chose to 3D print the body and laser cut the wheels to give us more

accuracy when designing

• We also chose to use a propeller to eliminate some of the electrical work that

comes with using a solar panel

ACTUAL DESIGN

• 3D printed body of car

– T

• p picture is dragster design

– Bottom picture is base – Bottom and top connected with pegs in holes

• Propeller attached to motor set out of

hole in the back of the base and then to 9 volt battery

• Axels attached with hot glue
• Laser cut wheels

MARKETING VIDEO

CUSTOMER FEEDBACK AND RESULTS

• Prototype showed to two boys, ages 6 and 8

– Interested about the idea that you could change the body style – Wanted multiple cars to be sturdy enough to be rough with – Brought up the idea of adding on “fast packs” which would essentially be more powerful motors to make the cars go faster

COST AND TIME ESTIMATE

• Prototyping costs: $13.79

– Axels: $1.55 – Propeller: $0.44 – Motor: $1.93 – 3D printing cost: $3.20 – Battery terminal: $0.44 – Velcro: $1.24 – Toggle Switch: $4.99 – Batteries not included

• Cost per 1000 units: $8,990

– Buying in bulk, decrease price by 35%

• Retail price: $29.99
• Design time: 19.25 hours

– Data from Project Notebook

CONCLUSION

• The biggest obstacle we had to overcome was the time constraint of 3D

printing

– Our design is simple but because we tried to print 4 wheels and the body it was difficult to build quickly while waiting for the parts to finish

• We stand by the quality of our product and believe it will be successful in the

market because of the versatility and simplicity of the design

• If we were to redesign the product, we would make the entire car wooden and

not 3D print the body
