90% printed reprap
thingiverse
In this project, I'll focus on printing most non-printable RepRap parts. The structure will resemble a MendelMax (http://mendelmax.com/tikiwiki/tiki-index.php?page=MendelMax), and OpenRAIL linear bearing system (http://www.kickstarter.com/projects/openrail/openrail-open-source-linear-bearing-system) will be used. A single part, measuring 2x2x11cm, weighs 20g and requires 3 perimeters and 80% infill to complete in about an hour (75mm/s). With these settings, the total weight of plastic extrusion for a MendelMax is approximately 900g (around €17). To create a complete bar, you'll need three pieces (60g of PLA) and eight pins for joints. By referring to this spreadsheet (https://docs.google.com/spreadsheet/ccc?key=0Ao-fptzJAVfGdDdnd3htckhZUVdWUTdvRnJQUEJrMUE&hl=en_US#gid=0), I've created various types of extrusions, including four 105mm lengths resulting in a total length of 420mm.
