You can definitely make money with a 3D printer! If you're creative and have tons of ideas, why not try to sell the print files on eBay, Amazon, Etsy, or Shopify? From what I've seen there is some search there. The opportunities with a 3d printer are as limitless as your imagination. You can make dnd figures, fan figures, toys, kitchen tools, and more! You can even rent out your printer, or teach classes to beginners. There are so many things you can do despite just selling products!
