Another common weakness in these designs is to use the extruded metal surface as the linear guide. Their primary weakness is that 3D printed parts aren't very rigid, so the precision, repeatability, and surface finish of parts created on these machines is limited. Given the ubiquity of 3D printers nowadays, these designs are extremely accessible, maybe moreso than wooden designs. Many of these designs don't require metalworking skills of any kind except to cut metal tubes to length. The Mostly Printed CNC and others like it make use of cheap extruded metal tube to serve as bones and 3D printed parts to serve as joints. You should use the most rigid material you are able to work with. The frame is the main body of your machine.
