Human: MaplePrint Mini RepRap 3D Printer Original Developer: Ryan Adams Date: 02/26/2015 Release: 0.1 Contact: @MiniMadRyan Overview The MaplePrint Mini is my first RepRap designed printer. Primarily, the main goal was to develop a printer that replaces traditional rods or laser cut frames with entirely 3D printed parts without losing rigidity or strength. Secondarily, I aimed to create a printer with a footprint larger than 200x200x200mm, thus making it printable on most 3D printers with a 200mm build volume. The overall print volume is slightly less than 100x100x80mm. With some creative engineering and swapping the extruder to a Bowden setup, you can squeeze even more out of it or modify the frame to be even larger and print bigger. Build Notes This is the initial release of the files and source materials for this printer. At this point, there isn't a complete build guide available, but I will provide one in future revisions. For now, you can try using the provided CAD drawings as a starting point. Electronics Notes The printer uses a standard RAMPS 1.4 install with Eric Zalms Marlin firmware: https://github.com/ErikZalm/Marlin I have included a quick and dirty config.h to get you up and running. Power wise, I used a cheap 12v laptop style brick to bring things to life. Parts list This is by no means a complete list of every part you will need, but it's a good starting point. For this project, most parts were sourced through www.FolgerTech.com and www.printrbot.com. Screws came from Fastenal and local suppliers. I will revise this list in future revisions.
