Safety Training Requirements[edit | edit source]

Safety Issues With Method[edit | edit source]

  • Extrusion nozzle is very hot during and after operation
  • Bench scraper is sharp and can cut skin
  • Filament cutter is sharp and can cut skin

Personal protective equipment.[edit | edit source]

  1. Safety glasses – always required
  2. Needle nose pliers - if needed

SDS and other[edit | edit source]

Knowing what chemicals are in the lab and how they interact with each other is critical when accidents happen.

  1. Appropriate SDS sheets should be viewed online.
  2. Note the hazards listed on the door to the lab. If you introduce any new equipment or materials you must clear them with the responsible person listed on the lab door. If the responsible person is out of date, contact the departmental administrators to get it updated.

Calibration & Tolerances[edit | edit source]

Calibration[edit | edit source]

  • Dual-mode leveling - both manual and automatic
  • When in lowest position, nozzle should be 0.1mm above print bed
  • This can be checked by moving a piece of standard A4 paper underneath the nozzle, there should be slight resistance
  • Most consistent way to achieve this:
    • Start automatic leveling and wait for this to finish
    • Switch to manual leveling
    • Move nozzle to any corner (buttons on screen), and adjust leveling screws so nozzle is 0.1mm away
    • Repeat for the opposite corner, then the two remaining corners
    • Move nozzle back to first corner, and adjust
    • Repeat in a Z pattern to 3 remaining corners
    • Move nozzle to the middle position and check distance away
    • If needed, run automatic leveling again, then check
    • If needed, adjust the Z-axis offset to get nozzle the right distance

Tolerances[edit | edit source]

  • Usable filament diameter: 1.75mm
  • Layer height: 0.1 - 0.4 mm
  • Resolution: 0.1 mm

Operation & Procedure[edit | edit source]

  1. Install a 3D slicing software - The Cura Slicer is loaded onto the SD card that comes with the device
  2. Acquire the part you'd like to print in .STL format
  3. Load the .STL into the slicer
  4. Adjust print settings to fit the needs of the part
  5. Add supports where needed and adjust support settings
  6. Slice the model to generate G Code
  7. Load filament into extruder
    1. Place the filament roll on the stand
    2. Use filament cutters to cut the end of a filament at an angle of 45 degrees or sharper
    3. Feed filament through the filament sensor and into the top of the extruder, you will need to hold it in place
    4. On the screen, enter a value of ~25 to the "IN" function
    5. Hold/press the filament in the nozzle until some starts to drip from the nozzle
    6. Stop holding the filament and wait for the gear at the top of the extruder to stop turning
    7. Use needle-nose pliers to remove any excess filament
  8. Preheat the nozzle and print bed to the temperatures needed in accordance with the material in use
  9. Download the G Code onto an SD card
  10. Plug the SD card into the printer with the metal pads facing up
  11. Use needle-nose pliers to remove any excess filament
  12. On the screen select "Print," then the name of the G Code Final, then Start Printing
  13. Wait for print to finish
  14. Remove part from the print bed using the bench scraper
  15. Clean the print bed

Shutdown[edit | edit source]

The printer can not be shut down using the mechanical on button, the screen must be used. Navigate to settings and select "OFF" then select "YES"
