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)

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

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

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)

The NerdyN (author)W1ll14m2016-03-21

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

W1ll14m (author)The NerdyN2016-03-21

Didn't know that, thanks

The NerdyN (author)2016-03-18

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

W1ll14m (author)The NerdyN2016-03-19

What are you talking about?

The NerdyN (author)W1ll14m2016-03-21

:) (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

In the anglophone world, there are millions of people called William. So one of these several million people commented my printer. So what?

ookkkkk...... that my friend, will take Forever

The tip is to far off the surface,way too much glue is being pushed out of the gun,and speed up the motion to reduce the thickness,you my want to mod the tip by using a fine ball point pen tip with the ball drilled out,insert this into glue gun tip use a bit of hi temp epoxy to hold the tip in the glue gun tip

this is a crazily experimental project! maybe benefitial to print in larger scale to compensate the lack of control and resolutions... total thumbs up!

If it wouldn't interrupted

ThomasK19 (author)ZacharyJ112015-11-16

lol - I had just the same idea. But I guess the resulting output would still be to thick to be really useable. However, an awesome build. Lego is marvelous.

ZacharyJ11 (author)mchau22015-11-16

Sorry. *If it wouldn't interrupt your your use of your hot glue gun, you could try making a cone of sheet metal just as large as the glue gun tip and snipping the very top of it off so you had a very precise nozzle and welding it to the glue gun.
