# Layer By Layer

Layer By Layer is an online marketplace for the buying, selling, and sharing of printable 3D designs. We're going to make it possible to get the things you need and want by printing them yourself, from your own home. We want to allow anyone, technologist or amateur, to be able to use a personal 3D printer - so we decided to create an easy way for people to find and print great products.
