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.
