Lego 3D Printer 3.0

Hi there!

A few months ago I've built the 2nd version of my Lego 3D Printer, and today I'm going to show how to build the 3rd version.

Step 1: Watch the Demonstration Video (optional)

Step 2: What You'll Need (for the X and Y Axis)

Step 3:

Step 4:

Step 5:

Step 6:

Step 7:

Step 8:

Don't forget the Lego doors for equilibrium

Step 9: What You'll Need (for the Z Axis)

Step 10:

Step 11:

Step 12: What You'll Need (for the Extruder)

Step 13: Don't Forget the Gluegun AND the Paper Clip

Step 14: The Extruder Should Look Something Like This

Step 15:

Step 16:

Bend the paper clip in a way that it partially stuffs the hole of the gluegun nozzle. This will allow for a more controlled extrusion process.

Step 17: Voilà

Step 18: Tipp

Use elastic bands to strap the paper (on which you'll print) to the moving platform

Step 19: The Result of My Test Print

Step 20: The Mindstorms Code I Used for My Test Print
