Projet CJP 660

• Blender workflow for color printing

Issue with lines on texture in 3D Print (not visible in Blender): https://support.capturingreality.com/hc/en-us/community/posts/115001620231-Big-seams-of-the-texture-when-printing-model-on-ProJet-660-Pro - hmm.. texture was 2x2k. Try maybe a UV render with larger spaces between the islands?

• Check power status print-computer. No sleep or screen saver.
• Raise build plate (!)
• Clean the parking caps.
• Clean the service station.
• Clean the spreader roller and scrapers.
• Clean the fast axis rails and carriage.

• Leave print in build chamber for 2 hours to strengthen the glue.
• Vacuum excess core material.
• Raise buildplate.
• Clean the debris separator grille.
• Clean the parking caps.
• Clean the service station.
• Clean the spreader roller and scrapers.
• Clean the fast axis rails and carriage.

• Depowder the print
  • First using the air wand
  • Then using brushes
  • Finally using picks for crevices and hard to reach places

• Dry the print
  • Oven: 50°C for about 1 hour (or 40°C for 2-4 hours)
  • Room temperature: The part will also be dry enough at room temperature after about 15 hours (overnight).
• Prepare the workstation: get all supplies ready
  • Supplies
    • Protection gear
      • Nitrile gloves
      • Breathing mask
      • Safety glasses
      • Clothes & shoes should be covered when infiltrating. CA glue stains will not come off of them.
    • Paper towel
    • ColorBond
    • Nail bed (or freezer paper, or wax paper)
    • A plastic bin (PP/PE plastic, glass, metal). Get a few different sizes of plastic bins to avoid wasting ColorBond.
    • A funnel
    • A downdraft table or fume hood for ventilation
  • Place a sheet of non-stick material (Te�on, freezer paper or wax paper) on your work area for easy clean-up and to put your parts on as they cure.
  • Have a good supply of paper towels ready for absorbing excess ColorBond.
  • The workstation should be well lit.
• Dip
  • Dump all colorBond into the bin
  • Submerge the print in the liquid.
    • It will start to bubble. This is the remaining air being pushed out by the infiltrant.
    • Once the bubbels stop coming (or after ±10 seconds), your part is completely infiltrated
    • If the print is too big to be submerged, drizzle the ColorBond over the part.
      • “For most parts we douse/pour over the glue. Get two waves of glue over all exterior surfaces in order to saturate it and achieve a uniform finish.”
  • Remove the print
    • Keep the part moving in your hands while excess liquid drips back in the container so it does not stick to your gloves.
  • Dab-off excess ColorBond with a paper towel.
    • Don't wipe with the paper towel (!)
    • The print will become warm and may emit visible vapor(!). This is normal.
• Cure
  • Put the print on the nail bed (or wax paper) to dry for ±30 minutes. Cure and cool time depends on your part’s geometry, but most parts are safe to touch within 15 minutes.
• Clean
  • Using a funnel, pour the leftover ColorBond back into the storage container.
  • Clean bin well with paper towels. Dried out ColorBond will flake and will contaminate prints the next time it's used.
  • Soiled paper towels can be safely disposed of as soon as ColorBond has cured. This usually happens within 15-30 minutes.
  • Cured ColorBond can be removed with nitromethane, a clean-up solvent for instant adhesives.
• Post Processing
  • Sanding
    • Start with 100-grit paper and continue to 220-grit if a smoother �finish is desired.
  • Painting
    • Parts in�ltrated with ColorBond can be painted without additional processing. For the best surface �finish, sand lightly, use a primer, and then apply paint.
  • Joining
    • For a plastic-like fi�nish, �fill in the seam of joined parts with Bondo® No.907 Glazing Spot Putty, apply 1-2 coats primer, sand lightly, and paint.

Storage:

• Unopened ColorBond can be stored at ±4°C (in the fridge). Then it's shelf life is 1 year from date of manufacture.
• Opened ColorBond should never be stored refrigerated.
