Intro: DIY Glow 3D PrinterIf you read my interests, you probably know that I love studying the 3D printer we have at school to see how it works. I spent about a month (as an engineering student Iknow how important research is) sketching designs and building prototypes. After that I finally found a design that fit my needs. This printer is based on the brain of amindstorm NXT because it is easy to program and my arduino chip is burnt out and I'm still trying to save up to buy a new one. This printer only prints as accurately asyou program it, but I will show you the best method of programming. The design includes x-axis and y-axis movement as well as z-axis movement used to pump downthe printing material.Time to make: about 4 hours if you have all of the pieces in front of youParts: Lego mindstorms kit and assorted lego box as well as a hot glue gun, tin foil, string, a printer, ink for the printer, a computer, and power to you house.What did you make: I used the above parts and about a months worth of research to develop my design for a 3d printer that prints out a glowing material as accuratelyas you can program it. Not nearly as good as an industrial one, but a great project nonetheless.How did you make it: I worked alone and used the 3D printer in my school as reference to how to build one. I had about 50 different design sketches before I started toprototype and then I had 3 prototypes.Where did you make it: I created this in part at school (sketches) but mostly at home. I spent whatever extra time I had free from homework to work on this project.What did you learn: I learned the importance of good and thorough research as well as refining my skills as an engineer.

Step 1: Before you start...The type of 3d printing shown in this instructable is called extrusion printing. This is when a hot material is programmed to be applied layer by layer to a surface in orderto create a 3d object. In this process, we use hot glue as the material. This process can use multiple colors too! If you have a look at this link you can see how to makeyour own or you can buy color hot glue sticks.Motor Uses: two motors for x-axis and y-axis movement, one motor for applying the hot glue.How it works: The two motors move a base plate any direction and then hot glue is streamed down using the third motor.Glue gun preparation: For this to work, you will need to open up your hot glue gun and remove the trigger. MAKE SURE IT IS UNPLUGGED FIRST. This will allow thehot glue to be freely pressed down. Be careful not to disturb any wiring inside and remember, these companies like to hide disassembly screws underneath stickers.

Step 2: Assembly x-axis movement part 1Part 1 covers basic x-axis movement.There are some parts that are not included in this step that you can either find or you can find alternatives

Step 3: Assembly x-axis movement part 2A continuation of basic x-axis movement
Image Notes1. This prepares you for y-axis movement

Step 4: Assembly x-axis movement part 3Preparation for y-axis movement
Step 5: Assembly y-axis movement part 1This part will go over the basic gear structures and how they interact to accomplish y-axis movement.
Image Notes1. The gear rack sits on this gear
Image Notes1. The plate from the next step will go here
http://www.instructables.com/id/DIY-Glow-3D-Printer/
Image Notes1. These are used later in programming
Image Notes1. To keep the plate level
Image Notes1. Almost done with basic movement!
Step 6: Assembly y-axis movement part 2This shows you how to build the basic platform and the plates that hold it in place
Image Notes1. Make two of these that are opposites of each other2. Plate to keep the central platform from rising
http://www.instructables.com/id/DIY-Glow-3D-Printer/
Image Notes1. Opposites
Image Notes1. They should fit snugly here
Image Notes1. These racks are essential for y-axis movement
Image Notes1. Make sure this is 2/3 a full brick (two 1/3 layers)
Image Notes1. Use these to insert the central platform into the holding area
Step 7: Assembly z-axis structure part 1The start of a very tall 3d printer...

Image Notes1. Make two that are opposites

Step 8: Assembly z-axis structure part 2Connecting the structure to the x-axis movement
Image Notes1. These are extremely important. They hold the x-axis movement on a line
Image Notes1. String will go through these holes
Image Notes1. make sure it is securely fit
Image Notes1. I used one of these to keep the string in place because I don't want to addadhesive to the precious legos
Image Notes1. This is right (completely straight)
http://www.instructables.com/id/DIY-Glow-3D-Printer/
Image Notes1. This is wrong (the string is at an angle)
Step 9: Assembly z-axis structure part 3Building the resting platform for the z-axis glue applying mechanics
Image Notes1. Two layers2. One layer3. One layer4. One layer
Image Notes1. Two layers here on the bottom

Step 10: Assembly z-axis structure part 4Making the glue-gun holding platform and adding to the height of the printer
Image Notes1. The glue gun will have free z-axis motion here, I sanded down the edges so thatit could move more easily

Image Notes1. The part made in the previous step
Image Notes1. Make sure these are VERY securely attached
Image Notes1. You can start adding wires
Step 11: Assembly z-axis structure part 5This adds much needed support and weight to the back of the printer. It also includes two touch sensors that you can implement in your programming if you wish

Step 12: Assembly z-axis structure part 6Preparing the glue gun connections
Image Notes1. Sand down the edges for easier movement
Image Notes1. Make sure it is 2x7
Image Notes1. Most structurally stable place to add the strings
Image Notes1. These string need to be very tight. Do not let them hang loose

Step 13: Assembly z-axis structure part 7This is a very important gear train that slows down motor speed and increases power output. This makes for a very precise z-axis linear motor

http://www.instructables.com/id/DIY-Glow-3D-Printer/
Step 14: Assembly z-axis structure part 8This is a platform to keep the z-axis pusher in line and make sure it does not move too far one way or another

Step 15: Assembly z-axis structure part 9This shows parts necessary to attach the z-axis pusher to the rest of the printer

Step 16: Methods of printingThings you can print on: I would highly recommend printing on tin foil as the hot glue doesn't really stick to it, especially if you freeze it. I have found that adding oil orother non polar substances so that the glue has little risk of sticking to the foil. I DO NOT recommend printing straight onto the plastic for a few reasons: if the plasticmelts, BAD things will happen; if BAD things happen, I take no responsibility. Just don't print straight onto the platform. Be safe about it.
Image Notes1. I would NOT recommend applying straight onto the platform
Step 17: ProgrammingSince programming needs a lot of motor use that slows down the software, I would recommend the use of MYBLOCKS. If you don't know how to use them, you can seehow here .
Steps of programming:1. Print out a picture of whatever you are printing. If you are printing something with multiple layers, do this one layer at a time and make sure you keep them in order. Iwould suggest making a separate MYBLOCK for each layer of the print.2. Go into the NXT and move to "View". Then choose the motor and move it. You can then program the motors in degrees. I would keep motor speed between 20 and 40percent. If you want to program curves, you can uncheck 'wait for completion' on the first motor block and keep it on the next one. Then they will run at the same time andif you have x and y axis movement you can create a curving motion. Throughout the build, features were added that make for easier data logging.3. Use sounds to say when it is done or when the glue gun has run out of glue. These are very helpful.

Step 18: Start printing!You can print a large amount of things with this printer. I started by printing a few layers (5 I think) to make a 3d 'S' for Searx. Once you get good at programming layers,you can go for something larger such as a 3d head or something. If you make something out of this printer, post a comment with a picture! After printing, go ahead andturn off the lights and pull out an ultraviolet light to make your creation glow!

wilgubeast says: Apr 2, 2013. 11:40 AM REPLYVery well done. Any chance you could swap in your own print material? Maybe a caulking gun full of Oogoo? The device itself is solid, but hot glue isn't themost robust material in the world. (Which is a silly quibble given that you MADE A 3D PRINTER.) Awesome work.
