RepRap Buyers' Guide
Entries on this page are in no way an endorsement of quality of goods or service. Below is simply a list of suppliers. Do your research by Googling <company_name RepRap forum> before you buy. This will usually find other reprappers' experience with a given company on our forums.
RepRap is open-source hardware, 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 RepRap parts or complete kits.
To remain fair, all vendors that sell here are up for review. Please note that, because this is the internet, it is very easy to fake accounts. Please pay more attention to reviews of people that have 50-1000 posts in our forums than people that have only 1 post, regardless of whether it's negative or positive. We have had some problems with vendors creating accounts and trashing other vendors, or posting good reviews for themselves.
If you get bad service, say so on the forums and help other reprappers. Also say if you get good service (it is human nature to complain more than to praise; so do this to keep an objective balance). Some vendors have links to reviews on the RepRap forum. If you wrote a review, mention it on the discussion page.
There are several subforums in the RepRap Marketplace and Job Shop, where people who have sets of RepRap parts for sale can advertise the fact and others can post requests to buy. Caveat emptor - while we try to keep complete rogues and con artists off this forum, it is open to the entire planet. Don't send money unless you're confident that you know what you're doing!
Also take a look at fellow RepRap developers selling printed parts on the wiki.
Project specific parts
Many project description pages in this wiki have a "Get it!", "How to get it" or similar section. So, if you're looking for something genuine, watch out there.
Also, projects usually come with a parts list / bill of materials (BOM). Many of these lists include links to vendors (such as hardware stores).
Stepper motor vendors can be found on the stepper motor page.
Filament suppliers can be found on the Printing Material Suppliers page.
All these vendors have an assortment of kits and/or parts specific to RepRaps. The list is non-exhaustive and contains both, good and bad quality RepRap-oriented vendors.
