What is a RepRap?
Prusa Mendel Iteration 2 Complete Kit
These are the latest parts and vitamins for the Prusa Mendel. The Prusa Mendel is the most common RepRap printer and it's the best printer for new reprappers. This kit includes everything you need to build a working RepRap and with NWRepRap's free support, you will get it working. The Prusa 2 has an effective print area of 180mm x 180mm x 130mm (7" x 7" x 5"). It can achieve a print height of 0.1mm to 0.3mm and it's accuracy is between 0.01mm and 0.02mm. See below for a complete list of what's included and what you'll need to build your first RepRap.

The nuts and bolts in this kit are metric. By supporting metric components, we encourage manufacturers to migrate to metric which is superior to SAE measurements.

The plastic parts in this kit are printed with a density of 70% which is higher than the standard 40% minimum density for RepRap parts. We believe it's important to have higher density parts for a more rigid machine. This helps produce higher quality printed parts.

We provide a 90 day warranty on everything and we don't ask questions. If a part or component breaks or if you break it on accident, let us know and we'll ship a replacement as quickly as we can at no charge.

Support is free as well and we like to think we're good at it. If you have any questions, call or email us between Monday and Friday (8am to 5pm PST) and we'll be here to prove it to you. You can also take a look at our support page where you might find what you need. Go here for our support page.

All the software for this kit is free and open source. We've created a page with download links to make it easy. Go here for the software.

We have very thorough assembly videos which will guide you through the entire assembly process. Go here for our assembly videos.
