Projet CJP 660

  • Check power status print-computer. No sleep or screen saver.
  • Raise build plate (!)

Post print steps and cleaning

  • Leave print in build chamber for x minutes (LOOK UP DURATION)
  • 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 (Teon, 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 inltrated 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 finish, 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.

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?

How much does it cost?

( build material cost ) * material multiplier )
+
( machine time (in hours) * machine time cost )
  • Ink & binder: ±€0,31 per ml
  • Plaster powder: €0,11 per cm3
  • Colorbond infiltration (optional): €0,32 per gr
  • Material multiplier: 25% (build material * 1,25)
  • Machine time cost: €0,55 per hour
