Topic: Watertight

So last night I made a tube 37 mm radius (6 mm thick walls) that was 74 mm high.  I attached it two two ends that I had and tried to run water though it (filter experiment).

Turns out the walls of the tube leaked like a sieve. 

Any ideas how to make it water tight?

180 C, PLA, 100 C bed temp, 50% fill.

Re: Watertight

First, calibrate your extruder stepper if you haven't (http://www.soliwiki.com/#Calibrations).  If you have done those, increase your # of perimeters to 2 or 3.  As a last resort, increase your flow rate within the "manual" tab of Repetier Host (or preferably in your slicer).

Re: Watertight

If the problem persists you could try painting some low vis epoxy on over the surface intended to be watertight or even paint it/ clear coat it (with multiple wet layers)if the leaking is minor.  Acetone smoothing might help as well....

Re: Watertight

Thanks,
extruder has been calibrated, but will try perimeter increase and flow rate increase.

Re: Watertight

Thought about epoxy or paint, may give it a try.

PLA doesn't respond to acetone smoothing, unfortunately.

Thanks.
