3D Printers

Introducing our 3D printers:

MakerBot

Robo 3D

Taz Lulzbot

Printing instructions:

Desiging your own 3D model:

Software: OpenSCAD

Cheat Sheet: http://www.openscad.org/cheatsheet/index.html

After creating your own 3D model follow this steps:

• Render and compile your code by pressing F6
• Export the design as .stl
• If the file is in your own computer, move the file(name.stl) to the Mac found in Turing lab(CST 222)

Instructions on how to use the 3D printers:

Robo R1+ 3D Printer

Software for the printer: MatterControl

Steps to follow in order to print:

• Insert a microSD card into the Mac and get rid of any files in it.
• Open MatterControl and drag your .stl file into the QUEUE section of the application.
• On the top-left section, click on “Select Printer.” Select “Robo 3D TM Turing” in the window that pops out.
• Towards the bottom of the QUEUE section, you will find a “Queue” button. Click on it to get a list.
• On the list, below GCode, select “Export to Folder or SD Card.” Click on the microSD card under “Devices” in the side panel and click on “Export”
• Now, in Finder, browse to the microSD card and rename the file you just exported as “auto0.g” (auto zero dot g). Choose “Use.g” if a prompt appears.
• Then, safely remove the microSD card from the Mac and insert it into the Robo 3D printer.
• Prep the build plate using one the following:
  • Glue Stick
  • Vinyl Sheeting
  • Hairspray

Apply whichever product on the surface of the build plate enough to cover the surface you will be printing on.

• Turn the printer on. Your print will start after about 5 minutes.
• After the print is over, wait for the temperature to cool down and carefully remove the 3D printed object from the build plate.
• Clean the build plate.

Software for the printer: Cura

Steps to follow in order to print:

• Insert a microSD card into the Mac.
• Open Cura and press “Load Model” to upload the stl file you want to print.
• Right click “Control” and select the “Save gcode” and then choose the SDcard under the “Devices” panel.
• Make sure the Taz 3D Printer is turned on.
• Safely eject the sdCard from the Mac and insert it into Taz Printer (on left side of the LCD screen)
• Back on the LCD screen, press the knob, scroll down by rotating the knob and select “Temperature”.
• Select “ABS” from the list shown.
• The LCD will now display the info screen and the printer will start heating up. Wait until the temperatures reach 240C and 110C.
• In the info screen, press the knob again. Scroll down and select “Print from SD” Select your file and it will start printing right away.
• Once the printing has finished, wait for the bed to cool down and carefully remove the 3D printed object.

MakerBot 3D Printer

Software for the printer: ReplicatorG

Steps to follow in order to print:

• Insert a microSD card into the Mac.
• Open ReplicatorG, drag and drop your stl file into application screen.
• Adjust your model if you need to.
• Select “Generate GCode” on the bottom right.
• Make sure the values are set as shown in the image below and then select “Generate GCode”

• If prompted with an “Acceleration Warning” select “OK”
• Wait until it generates the gcode.
• After the file is generated go to the gcode tab and modify the numbers on the lines M104 should be 230 and M109 should be 128, i.e.:

M104 S230 T1 (set extruder temperature) M109 S128 T1 (set HBP temperature)

Make sure to save it by pressing “Command + S”.

• Select “Build to file using SD Card” as shown in the image below. Select the microSD card and make sure to save it as “.x3g” format.

• Wait until it is done building and then safely eject the sdCard from the Mac and insert it into the MakerBot. Note: You can find the sdCard slot as shown in the image below:

• Turn on the printer.
• Select “Build from SD” and then using the arrows scroll down to your file.
• The printer will start heating up and once it finishes heating up, it will start printing.
• Once the printing has finished, wait for the bed to cool down and carefully remove the 3D printed object.
