Random Task - Isopropyl Filtering

So i haven't done any printing of late.

Have been modelling up the Thunderhawk reboot which is taking quite a while. Should be worth the effort though.

I did make it down into the garage on the weekend, and random, spur of the moment thing filtered the isopropyl.

Year 7 (or less) chemistry. Nothing but homebrew lab equipment here. Funnel + paper towels.

The first cleanup ('dirty') bath had somehow developed a chemical 'custard'; hanging from the liquid surface, on the container surface. Basically a suspension in the liquid.

Managed to filter out the sludge pretty decently. Bit of wastage but better than having to chuck the entire container. The orange juice (picture) is pretty much the final parse, and it turned out very clear, minimal sludge.

Previously i had placed a different 'dirty' bath directly in the sun (when i was using the smaller containers - to evaporate the iso and cure the residue for disposal) and a similar suspension and custard skin formed.

Interestingly the 'clean' bath didn't form the suspension - it was sitting right beside the 'dirty' container so subject to all the same environmental conditions, except less resin. The 'clean' iso also got a parse through the filter - just because.

So ready to print.

Until next time...
