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 diameter, filament, the top fill pattern, and slicer are all factors in making watertight vase mode vases.

Vases Holding Water for More Than 2 Weeks

Bottom diameter – 75.2 mm; Height – 76.6 mm
Printer – Prusa MK3s+
Slicer Prusa – concentric top fill pattern, ironing enabled
Filament – PLA, Pink, Push Plastic


Bottom diameter – 40.9 mm; Height – 41.4 mm
Printer – Prusa MK3s+
Slicer Prusa – concentric top fill pattern, ironing enabled
Filament – PLA, Pink, Push Plastic


Bottom diameter – 19.8 mm; Height – 20.1 mm; two of the minivases have an optimized bottom
Printer – Prusa MK3s+
Slicer Prusa – monotonic top fill pattern, ironing enabled
Filament – PLA, Pink, Push Plastic

My testing is over for now. What are your thoughts about the testing?
