Water Tight Prints

Recommended Posts

I recently printed a part on my UM2 hoping it would be water tight, but the base layer seems to be porous. Side wall seem okay.

Any ideas on why the base layer would not be water tight?

Slicer: Cura

Settings : Set to Fast (I didnt tweak anything, just used the basic fast setting)

Material : Clear PLA

Specially on the base layer, but also on the walls you need to overextrude, set flow to something like 120 - 140 % depending on nozzle size, also works well in "spiralize" mode.

For this print it's an easy repair, just coat the inside with PVC glue.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
