3D printing marketplace

3D printing marketplace is a website where people who have 3D printers can sell their products. On the website, buyers can browse through the products made by different 3D Printer owners and purchase the items they want. The 3D Printer owners will then print and ship the product to the buyer. It is like an online store where people can buy things made by 3D printers instead of buying from a store.
