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)
  
 +
=== '''Overhang / Supports''' ===

+
Once you import a pre-existing model:
 +
* Use the align tool under the Edit tab to place model on bed
 +
* Use the overhang tool under the Analysis tab to generate supports for the model
 +
* Export as " *.stl " when finished

==== '''Robo R1+ 3D Printer''' ====
  
 +
Software for the printer: MatterControl
  
 +
Printing from an SD card:
 +
*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.
  
 +
Printing from the computer:
 +
*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.
 +
*Under "Settings" ensure that the correct material is selected.
 +
*Under "Controls" an offset of 0.9 typically shows the best results.
 +
*Pre-heat the extruder and bed on the same page.
 +
*Alternatively, near the top center of the screen, an extruder temperature and a bed temperature will be shown, mouse over and click "pre-heat" for both.
 +
*Prep the build plate using one the following:
 +
**Glue Stick
 +
**Vinyl Sheeting
 +
**Hairspray
 +
*Click print once the printer has heated up.
 +
*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.

Revision as of 13:52, 6 June 2017

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)

Overhang / Supports

Software: Meshmixer

Once you import a pre-existing model:

  • Use the align tool under the Edit tab to place model on bed
  • Use the overhang tool under the Analysis tab to generate supports for the model
  • Export as " *.stl " when finished

Instructions on how to use the 3D printers:

Robo R1+ 3D Printer

Software for the printer: MatterControl

Printing from an SD card:

  • 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.

Printing from the computer:

  • 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.
  • Under "Settings" ensure that the correct material is selected.
  • Under "Controls" an offset of 0.9 typically shows the best results.
  • Pre-heat the extruder and bed on the same page.
  • Alternatively, near the top center of the screen, an extruder temperature and a bed temperature will be shown, mouse over and click "pre-heat" for both.
  • Prep the build plate using one the following:
    • Glue Stick
    • Vinyl Sheeting
    • Hairspray
  • Click print once the printer has heated up.
  • 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.

Taz Lulzbot 3D Printer

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)
    • Make sure the SD card has the pins facing towards you when insert it
  • Back on the LCD screen, rotate the knob counter-clockwise to decrease the print speed to ~50%
  • Press the knob, scroll down by rotating the knob clockwise and select “Temperature”.
  • Select “Custom Temp” and set the "Nozzle" to 240 and "Bed" to 64
  • After a few seconds, the LCD will display the info screen again and the printer will start heating up. Wait until the temperatures reach 240C and 64C.
  • 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”
Replicator values.png
  • 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.
Build from sd.png
  • 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.
