The document provides instructions for post-processing parts produced by the ProJet 1000/1500 3D printers. It describes using the ProJet Finisher system to clean parts with a washing cycle and rinse cycle. It also details removing supports, sanding parts, post-curing parts, and refreshing parts with oils. Proper post-processing is important for achieving high quality parts from the ProJet 1000/1500 printers.

– Excellent surface resolution
– Excellent feature details.
• Overall part quality is determined by proper build setup
and part orientation as well as good post processing
techniques.

5. Post Processing Summary
• Remove excess
resin from part
surface
• Manually remove
supports and
smooth down
support nubs

6. Equipment for Post Processing
• ProJet 1000/1500 Finisher
– Two Tank System –
• 1st Tank holds 8-10 gals
of Clean-A-Part solution.
Wash excess resin
• 2nd Tank holds 8-10 gals
Water. Rinse
– Magnetic Motor with stir
bar to agitate liquid
– Timer
– Quick Connect Hoses for
filling and draining

7. Equipment for Post Processing
• ProJet 1000/1500 Curing
System
– Small UV oven that post
cures parts
– Timer and automatic
shutoff
– UV protective window with
safety interlock

8. Supplies and Hand Tools for Post Processing
Angled Snips
(included with Finisher
System)
Exacto Knife
Sandpaper, Files,
Sanding Blocks, etc.
Gloves if handling uncured
resin
Soft Bristle Toothbrush
Small bin of water or
isopropyl alcohol for
wet sanding

9. Power Tools for Post Processing
• Dremel MultiMax
– Uses oscillation instead of
rotation
– Rotary Tools can be too
aggressive and remove too
much material during
sanding
– Recommended MultiMax
Attachments:
• Sanding Block and pads
for sanding
• Cutting Tool for
removing supports

10. Cleaning Parts with the ProJet Finisher System
• Load Print Pad
• Slide the print platform into
the clips on finisher's on
each side of print pad
holder. Ensure that print pad
is fully seated in holder
(Figure 1).
• Wash Cycle
• Place the holder in the
solvent tank filled with 8-10
gal. (30L) of Clean-A-Part
solution. Press the timer to
start the 5 minute cycle
(Figure 2).
Figure 1: Load Print Pad onto holder
Figure 2: Wash Cycle

11. Cleaning Parts with the ProJet Finisher System
• Unload Wash
• Once cycle is completed, lift the
print pad holder out and set it on
the print pad clip to allow most of
the solvent to drip off the
part. Note: Allow the solvent to
drip off the part completely before
proceeding to the next step
• (Figure 3).
• Rinse Cycle
• Place the print pad holder into the
water rinse tank and press the
timer for the 5 minute cycle
• (Figure 4).

Figure 4: Rinse Cycle
Figure 3: Mineral Spirits will dissolve the
part material so rinse no longer than a few
seconds.

12. Cleaning Parts with the ProJet Finisher System
• TIPS AND BEST PRACTICES
– Use both platform
holders as covers when
finisher not in use
– Take one out and set
aside and only use one
holder while cleaning

13. Cleaning Parts with the ProJet Finisher
• Unload Rinse
– Once cycle is completed,
lift the holder and set it
on the print pad clip to
allow most of the water
to drip off the part. Note:
for best quality, blot
excess water with a
paper towel, or use air to
remove water from the
part before curing
(Figure 5).

14. Sanding and Finishing Parts
• Remove supports
– Use the snips that were
supplied with the
ProJet™ Finisher to snip
the supports connecting
the part and the build
foundation.
– Using Dremel MultiMax
and straight cutter or
yolk cutter, gently move
tool through supports at
lowest level

15. Sanding and Finishing Parts
• TIPS AND BEST PRACTICES
– Take care not to snip too
close to the part surface to
prevent a pit into the part.
Leave a small amount of
support on the part that
can be sanded down
– Support columns can fly
when snipped. Cover the
part with one hand while
snipping with another to
catch the flying support

16. Sanding and Finishing Parts
• Sand Parts to desired finish
– Sand excess support nubs
off part and finish to
desired smoothness.
– Wet sand with water or
isopropyl alcohol in a small
bin rinsing part
periodically to reduce
sanding dust and remove
debris from part.

17. Sanding and Finishing Parts
• TIPS AND BEST PRACTICES
– Excess resin can still remain
on part in crevices and along
edges. LOOK FOR SHINY
AREAS.
– Remove excess resin using a
soft bristle toothbrush
dipped in isopropyl alcohol

18. Sanding and Finishing Parts
• TIPS AND BEST PRACTICES
– Check holes and other crevices for excess resin
that may be trapped.
– Remove using pointed object (i.e. dental picks,
wooden sticks, paper clips, etc.)

19. Post Cure Parts
• Make sure parts are
completely dry and free of
sanding dust.
• Place uncured parts in the
ProJet Curing Oven for a 40
minute cycle. Parts will post
cure to a dry, hard finish. If
parts were post cured before
finishing, another curing
cycle is not required

20. Post Cure Parts
• TIPS AND BEST PRACTICES
– The Ivory material may
turn brown if post
cured for too long
– Reduce curing time to
25 minutes and check
to see if parts are hard
and dry to the touch

21. Refresh and Condition Parts
•
•
•
•
•
Sanding colored parts can cause scratches
Scratches can be masked to give part clean finish
by wiping or dipping in oil
Mineral oil, canola oil, vegetable oil and other
similar oils
Dip in a shallow bin, lightly spray on or wipe on
oil
Remove excess oil by wiping with towel or
washing with soapy water
