This equipment is safety category 3:

  • Mandatory, in person, instructions.
  • Make sure you read the Wiki before asking.

This equipment is Noise Category 3: Can be used at all hours. No limits.

Ultimaker printers

The Makerspace has two 3D printers:

  • Ultimaker 2 +
  • Ultimaker 2 Extended +

Both printer are operated the same. This manual is applicable to both printers.

Printing on the Ultimaker 2 + or Ultimaker 2 Extended +

Preparation: If you like you can do this at home

  1. Prepare the GCODE file(s)and copy it to a SD card

To print a 3D model:

  1. Enter the SD card with GCODE file(s) into the SD card reader
  2. Prepare the print table for printing, apply
    1. glue (for PLA) or
    2. painters tape (for ABS)
  3. Switch on Ultimaker on the back side of the machine
  4. Change material:
    1. To change material or the enter material in to the printer, choose Material in the main menu
    2. Choose Change. The machine heats up and first will remove existing material
    3. Choose Ready once material is removed
  5. Feeding new Material
    1. Feed new material on the back side of the UltiMaker
    2. Choose Ready once the material is transported through the tube. The material will be transported to the nozzle.
    3. Wait till material flows through nozzle and confirm by selecting Ready
    4. Return to main menu by selection Return
  6. Print model
    1. Select Print
    2. Choose model you like to print. The printer heats up to the required temperature.
  7. Printing
    1. Once the nozzle and print table are at the required temperature, the printer will start.
    2. Printer releases small amount of filament through the nozzle
    3. The printer starts printing
    4. The display shows the expected time for the print
  8. Print ready
    1. Allow the printer table to cool down. Too early removal of the print may damage the print
    2. Remove the print from the print table
    3. Clean the printer table when required (remove glue / painter tape)
    4. Remove the Filament from the printer by executing step 3 of this procedure
    5. Once the filament is removed, switch off the print with the switch on the backside of the printer
    6. Store filament in the appropriate location

Unattended running

The two white Ultimaker 3D printers are one of the few machines that can run unattended e.g. during the night.

Unattended printing on or two Ultimaker printer, that is leave the machine on and printing when you leave the building is only allowed when you follow below rules.

  1. Make sure you have enough PLA on the spool and check that it won't tangle as it unrolls.
  2. Only print with Ultimaker listed and approved material. E.g. normal PLA, with normal settings.
  3. You stay with the printer for the first 10 layers or 15 minutes to check the printing process.
  4. You accept that other members have the right to remove your print, when it is finished or failed.
  5. Plan to remove your print soon after it is finished, e.g. the next morning when you print overnight.

Please leave a note with your name and email, so people can contact you, when something looks wrong, or want to know what you planning.

Releasing clocked material from nozzle

Over time the printing nozzle can get clocked with filament. To clean the nozzle follow these steps:

  1. Remove remaning filament
  2. Get a 30cm of Nylon filament and straighten it as much as possible (there is a box with leftovers)
  3. Remove the blue horshoe clip underneath the white coupling
  4. Remove the filament tube out of the print head, while holding the white coupling
  5. Select in the main menu "Advanced"
  6. Select "Heatup Nozzle"
  7. Raise the nozzle temperature to 260 degrees
  8. Once on right temperature, insert the straightened piece of filament into the nozzle
  9. Set the temperature to 90 degrees and wait for the printer to reach this temperature
  10. Pull out the filament, be aware, this may require substantial force
  11. Repeat this process as often as required

Maintenance

See Maintenance Ultimaker 2+ for detailed descriptions on maintenance.

Recommended maintenance schedule

To keep your Ultimaker 2+ in optimal condition we recommend the following maintenance schedule, based on 1,500 printing hours per year:

Every month Every three months Every Year
Clean Printer Check for plays on axels Clean feeder and replace Bowden tube
Lubricate axles Check for tension of short belts
Lubricate lead screw Z moto
Re-tighten hot end isolator
