Challenges
Electric motors are expensive and difficult to manufacture, and not universally available. Most thermoplastics operate at low melting points not suitable for intense or prolonged motor operation.
Approaches
3D print an electric motor using recycled plastics selected specially for high durability and heat resistance, 3D printers, and vitamins. Design with investment casting, and direct metal printing in mind.
Stepper Motors
Dual-shaft NEMA-17 Stepper motor
Servo Motors
- AMT102-V inexpensive shaft mounted rotary encoder with adapters for various motor and shaft types
- Mechaduino servo controller
