Welcome to Roaddog Labs Ltd Documentation. These docs contain specs and information about the various Roaddog Labs Ltd kits and parts as well as build instructions and general information. Even though we've stopped selling kits and parts the docs are available so you can hack your own designs or build one of these.

Getting Started

To give you an idea on what building a DIY 3D printer is all about check out the general tips in our Getting Started Beginner Guide . It will walk you through some best practices of tools and work environment, how to manage expectations and tips for choosing a first build.

The names of the various DIY/Reprap style 3D printers can be very confusing particularly on a first build. What do those names mean? How are those printers different? We offer a new/first build comparison chart with our recommendations for new builders and and explain why we have chosen the suggestions we have.
