The RepRap II: Mendel is open source hardware and so there is not a single place to buy it but rather many options. This competition is encouraged so that prices become lower over time. Below is a list of places to find Mendel parts and/or kits.

For a spreadsheet containing the complete Mendel parts list together with listings of suppliers, see this page.

Note: it is not necessary to purchase a kit, many RepStraps are available either to buy or to build that can be easily assembled with tools you may already own.

Listings on this page are in no way an endorsement of quality goods or service! Below is simply a list of suppliers; If you would like feedback on a particular buyer, head to the forums.


There are many words and abbreviations that reprapers uses that you will be unfamiliar with, so we have created a glossary to help make things clearer.

For Sale Forum

We run a For Sale/Wanted Forum where people who have sets of RepRap parts for sale can advertise the fact and others can post requests to buy. Caveat emptor - we try to keep complete rogues and con artists off this forum, but it is open to the entire planet. Don't send money unless you're confident that you know what you're doing.
