Shapeways allows you to upload your 3D models and earn passive income. This is a great alternative to printing models your own 3D printer and selling them.
Your models cannot be downloaded by customers on shapeways which secures your intellectual property. Instead a customer orders your product through the Shapeways platform. The company then prints and delivers the product to the customer while you earn a percentage of the sales.
