Post Process Methods?

Post#1 » Tue Nov 11, 2014 12:54 am

I was thinking what was the best post process for getting prints fresh off the machine to nicely cleaned up and cured?

What im doing at the moment is:

[list]Print sprayed with 99.9% iso alc to remove the worst of residual resin.[/list]
[list]Throw it in the ultrasonic cleaner for 6 mins, using plain old tap water in there (am dubious about mixing heated ultrasonic electrical equipment with flammable alcohol!) [/list]
[list]Then in the UV cure chamber for 5 mins, 56 watts of UV bulbs.[/list]


Are we having much much success with any alternative process?

I'm using ISO directly in the sonic for more than year now. No problems so far.
Then water curing in UV (ordinary two pcs curing box 72W) for 0.5-3 hours (yes hours, I usually leaving it there for long).
And then blow dry - voila, ready. Dry, clean and nice to touch.

No Iso anymore, just soap and water in the ultrsonic for about 10 min. Blow dry and UV box for 2 to 4 hrs. If the item is flat i flip it about every hr. I leave the base on rings for curing so they stand up and get cured from all sides at same time (using solar turn table in double fingernail boxes with feet added. Use pull out bottom from on nail box as reflector "lid". leave opening for air to circulate or may get too hot (possible fire hazard).

AFAIK no - prints, if not left overnight will not be hurt. But still I saw real cracking on FunToDo resins if washed in iso for prolonged time (>5 minutes). Same on MJR if washed in ultrasonic fro long time and cured without water. If cured in water - no cracks.

Been using a high pressure water flosser to blast uncured resin off prints

Works like a dream (once you contain the overspray!)

My procedure is the same as Yoshi's. But i only cure between a quarter and half an hour.
I do not cast, so this might explain, why I get away with the shorter cure times.

Anyway I like the idea "to use a flosser" very much.

I am very interested in the water flosser! How do you contain the water and overspray?
