Oranj Reprap Prusa i3 3D Printer by Chad Wick [Work in Progress last updated Dec20,2019] ***This printer is almost complete. Please build the small version until firmware is made for the larger sizes or you know how to edit firmwares yourself. Contact me if needed.*** Unique Features: -Print from 20cm up to 50cm cubed print volume depending on which build you choose to make. -Upgrade to a larger printer anytime, as most parts are still usable after an upgrade. -Multi-material up to three colors with two bowden and one direct drive extruder -Fast(est?) 3D printer self-replication print times Tests done so far: -Direct drive and Bowden Extruders have been tested to make Benchys and work to a good level of print quality. -Very tall objects that max out Z height print successfully. -A basic version of Marlin firmware with auto bed level enabled works with the smallest 22x22cm bed printer design. What's left for me to do? -3D printed frame; test integrity of each printer size, make alterations if needed -Type up parts list -Make build instructions as text/images. Also make video build instructions. -Control boards and PSU enclosure need to be designed in CAD. May need a few designs made for different boards and PSU sizes. -Firmware for printer sizes larger than 20cm bed and to enable multi-color printing for boards that support three extruders Files in these folders correspond to the printer size you want to build: 22cm bed printer: "Oranj Printer Core Parts" + 22cm parts folder 30-40cm printer: "Oranj Printer Core Parts" + 30-50cm Shared Parts + 30-40cm parts folder 50cm printer: "Oranj Printer Core Parts" + 30-50cm Shared Parts + 50cm parts folder Fun facts: -This printer was designed in Maya because it's all I know how to use. -The name "Oranj 3D Printer" is mostly random. Searching on Google will lead to this Thingiverse design more easily because of the misspelling with a J. -Brief History; This printer started as a discontinued Prusa i3 clone from AliExpress with aluminum 2020 extrusion frame and acrylic parts. It was a poor design, so I remade all parts into better printable designs. tags: oranj 3D printer, reprap, prusa, filament, orange, open source, marlin Additional Information: -220mm bed carriage can be entirely printed on a Prusa MK2 or better at its utmost print area of 216.5 in Y by 220mm. Other sizes are modular and must be assembled. -If using metal extrusion lengths: -220x220x260: (20cm x4) OR (40cm x2) for Y axis... (23cm x2) for X axis... (23cm x4) OR (46cm x2) for Z axis. -420x420x460 & 320x320x460: (30cm x4) OR (60cm x2) for Y axis... (43cm x2) for X axis... (33cm x4) OR (66cm x2) for Z axis. -520x520x560: (35cm x4) OR (70cm x2) for Y axis... (53cm x2) for X axis... (38cm x4) OR (76cm x2) for Z axis. -MAX: 30cm extrusion prints can be made on a 20x25cm bed like Prusa MK2/MK3 on a diagonal. -MAX: metal heated bed is 30cm, for 40cm volume use 30x30cm heated pad on glass and 40cm heated pad for 50x50cm glass. -3D prints on corners will hold the glass plate to carriage. Aluminum sheet pieces taped under the glass bed will trigger probe for mesh bed leveling. -Holes distances and true bed sizes: -20cm bed: 220x220mm wide, 210mm space between center of holes -30cm bed: 327mm wide, 320.4mm space between center of holes -40cm bed: N/A (can't find, use glass and silicone heat pad) -50cm bed: N/A (can't find, use glass and silicone heat pad)
