Can Vases Be Printed Watertight in Vase Mode?

In the “Dura: PLA based biodegradable Nylon Analog” blog post, I mentioned that I had not tried using the optimized bottom/ironing-enabled method with other filaments. Later, I performed tests on vases using three types of filaments; Dura Nylon PLA, Pro PLA by 3D Printlife, and PLA by Push Plastic. The definition of watertight for these tests is the vase holds water for more than 2 weeks without leaking. The results of my tests are that vase circumference, filament, the top fill pattern, and slicer are all factors in making watertight vase mode vases.
