Welcome to

RepRap is humanity's first general-purpose self-replicating manufacturing machine.

RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...

RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too. is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. Our community portal and New Development pages have more information on how to get involved. Use the links below and on the left to explore the site contents. You'll find some content translated into other languages.

RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. It has become the most widely-used 3D printer among the global members of the Maker Community.

RepRap state-of-the-art when this page was last updated (June 2016) is well represented by the RepRap Snappy, RepRap Dollo and the RepRap Generation 7 Electronics. By state-of-the-art we mean the best self-replicators. These may not be the most technically advanced 3D printers, but - arguably - any self-replicator is, by that very fact, more advanced than anything that is not.

A family using one RepRap to print only 20 domestic products per year (about 0.02% of the products available) can expect to save between $300 and $2000:

"...the unavoidable conclusion from this study is that the RepRap is an economically attractive investment for the average US household already."
