Lego 3D Printer 3.0





Introduction: 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

    The metaphor of a 3D printer being a CNC glue gun has been floating around for ages.

    I think it's brilliant you made a 3D printer with an actual glue gun!

    Thank you for making the metaphor real.

    Mindstorms are too expensive to use in this way. I just checked price for a set $300.00+ per set. your printer with glue gun is very neat and I enjoyed your videos. If I am wrong on price I am sorry was just what I found on their web site.

    Do you have a parts list? Pictures reall don't help when trying to ID Lego parts

    and finally, don't use a hot glue gun, use a 3d pen

    The point of my 3D printer was to be made in the simplest way possible, using cheap material (although I admit the Mindstorms brick isn't very cheap)

    they only cost $20 or so you can actually 3d print objects with printer fillmient

    Didn't know that, thanks

    also, you might not want to make other accounts and comment yourself. (It doesn't look to good)

    What are you talking about?

    :) (i dunno the comment "This looks awesome. I never knew you could actually do something like this... keep going, because I think that if you use the mindstorms 3.0 with this one, it would look awesome!" -WilliamR79
