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.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
