Hi! My name's William and this is my first time on instructable.com

My first project is this Lego Mindstorms 3D printer. I've already built a prototype before this version, but the results were well...mediocre. This is the 2.0 version. It's more precise, more efficient and the printed objects are better than in the previous version, although far from perfection.

Step 1: Step 1: Building the X and Y Axis

You'll need:

- 2 large (16x32) lego plates

- About 30 Lego gear racks (4x1)

- Long and thin Lego bricks

I think that the image explains pretty well how to build the X and Y axis so I hope you won't need any further information for this step.

<p>Hi,</p><p>We're looking to hire someone who owns a LEGO 3D printer for an event. We would pay for services, travel and accommodation. This would be between October 15-18.</p><p>If you would be interested, please get in touch at anna.rust@socialbakers.com.</p><p>Thank you!</p><p>Anna</p>
Hi there! Thank you for your interest. Unfortunately I don't live in America so I don't think I'll be able to participate at your event. But again thanks a lot for your interest!
Hi, <br><br>We aren't based in America, the company is European and the event is in Greece. We would cover your travel expenses and the fees for using your printer.<br>If this is something you would be interested in, please in touch at anna.rust@socialbakers.com, so I can forward you on to my manager.<br>Thank you,<br><br>Anna
<p>Hey, I found this: <a href="https://www.instructables.com/id/Precision-Hot-Glue-Pen/" rel="nofollow">https://www.instructables.com/id/Precision-Hot-Glu...</a></p><p>The part where they modify the handle to make it a pen shape doesn't seem helpful for this, but do you think that you could modify the tip the way they did to make your 3D printer more accurate?</p>
<p>How did you make the glue come out?</p>
<p>With the extruder. The motor-powered wheel pushes the glue-stick into the gun, which fuses the stick and lets it come out in a liquid form. </p>
<p>Yeah, I tried that but its not working. Can you give me some tips on how to get the glue out?</p>
<p>Ah! I see waht you're saying. I had that problem too. The problem might be that your glue stick fits too tightly between the two wheels; in this case the motor-powered wheel spins and spins without pushing the glue down. </p><p>I went through several extruder designs until I found one that works (In the picture). If that still doesn't help, you should consider using another glue stick (since they come in many shapes) or maybe even another glue gun. </p><p>I hope my advice was helpful.</p>
<p>Pretty much exactly what I made 2 years ago https://www.instructables.com/id/DIY-Glow-3D-Printer/</p>
<p>Indeed, and I must admit your version was more practcal than mine, although the construction seems a bit complicated.</p><p>I hope that that it's ok for you you that I published my version. Also, since I'm new to &quot;instructables&quot;, I couldn't possibly know that another person built another Lego printer before me.</p>
The song is by Deorro, 5 Hours right?
<p>there should be a heated pad to take the object off. Amazing project though</p>
I recommend lowering the extrusion rate in corners and fixing the jitter it has when it starts on the back edge (it wiggles too much) <br><br>Awesome idea hope you keep perfecting it
<p>True, I hope to make a better version within the next two months. Thanks for your support :)</p>
awesome! would love to see some demonstrations. also why not use the ev3 brain as counterweight? I find mindstorm brains to be very heavy with all the batteries.
<p>That would be very clever. Haven't thought of it. Thank you very much!</p>
<p>dont surrender this concept has future </p>
<p>This is really cool! You could buy a real extruder for a little cash and then have a completely real 3D Printer! Nice work, though.</p>
I wonder if one could mod the hot glue gun to extrude in a more uniform and continuous way.<br>Maybe if there were a very thin strand of hot glue instead of a stick, or have a molten reservoir to pour from. <br>Super way to use what you've got to create something awesome!
<p>Nice! This is simple way to introduce kids into the 3D world :-)</p>
