  1. Both wheels (image shows the front) use the same shock absorber. Like the Peugeot (but smaller).
  2. Created a F1 car from the Peugeot 24H Le Mans Hybrid Hypercar [42156]. There aren't many gears in this box. But I've managed to include steering, a simple 2 speed gearbox, 6 cylinder engine, front and back suspension, drs. Instructions are available on Rebricable.
  3. 42158, NASA Mars Rover Perseverance Image from the LEGO site. ""
  4. A picture of the first improvement. Replaced the X-axis: The old X-axis will be reused to alter the Z- or Y-axis. Building instructions are on http://www.instructables.com/id/LEGO-3d-Printer/
  5. You can make a wanted list at Bricklink.com. An other way is to buy the education set and sell the unwanted items.
  6. The new X-axis (redesign) with the Z-axis coupling realy improved the print quality. Next step is giving the printer a technical look. The Z-axis can be replaced by a more technic tower, using new technic connectors. The green base plates can be replaced by the old technic bricks.
  7. Added some pictures with details of the mechanics. I'm currently redesigning the entire X-axis to the 'new' Lego technic. Most yellow technic parts are over 30 years old. I'm trying to use as less non-lego parts as possible. I replaced the loom bands on the right by springs. Replacing the stepper motors by Lego motors is to expensive at the moment. There are 5 steppers and 3 endstops. This means at least 2 ev3 sets.
  8. Update september 2015: I have build a new extruder for this printer. It's now capable of printing chocolate. ------------------------------ Although it's not a 100% lego build. I think it's worth mentioning in this forum. This fully-functional 3D printer is capable of printing 3D objects, including Lego bricks. The printed PLA bricks look like the first lego bricks from the early '70s. Switching to ABS will be a next step. The LEGO printer is based on the Prusa I3 rework printer. LEGO and Nema 17 stepper motors are a perfect match. A default LEGO brick of 4 by 2 studs is 32 x 16 x 9.6 mm. Nema stepper motors have m3 holes at a distance of 31 mm. Attaching the Nema 17 stepper with LEGO technic, using a felt damper/isolator and m3 x 15 bolts, gives a solid base. It's not a 100% LEGO printer. I don't have any LEGO Mindstorms products. Another reason is that LEGO motors are servo motors and 3d printers use stepper motors. Last reason is the software used to control the printer. I'm using Marlin for the Atmega 2560 and Pronterface on my laptop to control the printer. The base of the printer is 34 x 64 studs (19.2 x 51.2 cm) and is about 44 blocks high (42 cm). Y carrier belt: Attaching linear bearings. Z-azis motor and smooth rod: It took some time to calibrate the printer. But everything is working like it should. A picture of my latest print: The advantage of using LEGO is the possibility to alter the printer after building. More pictures, a video of this printer in action and building instructions are on: http://www.instructa...EGO-3d-Printer/.
