Best Parameters for Vases on K1-Max

I have been into printing Vases lately with many spiral and faceted designs. I am looking for the perfect balance of Strength/Quality/Print time/Watertight, with watertight not being negotiable. I have found that using Vase (Spiral) mode, the strength isn’t there, even with 0.6mm, or 0.8mm nozzles; and of course the finished surface isn’t as nice with the larger diameter nozzles. I tried a couple of designs using Brian Vines’ (BV3D) YouTube on “Fake Vase Mode” suggestions and got pretty good results; however, I still had some leaks in the spiral seams of the design by Streetfire_Industries posted on Thingiverse in 2017. I have also printed many Vases by WRIGHTMEDIA (Thingiverse) inspired by Devin Monte’s. They are all great designs, but I have had problems with leakage on the bottom and some in seams, unless I set layers to 4 (or more) and at least 20-30% infill. I am still a Novice, at this for only 2 years and have three Creality printers, but my K1 MAX is my go-to printer whenever I can use it. I love the auto set-up of calibration and leveling; the speed, the ease of filament change and nozzle change (with Micro Swiss Hot End and nozzle upgrade, and the ability to use just about any filament. I use PLA mostly for vases, but one comment I read on a forum, said that PETG was much better for vases (in Spiral Vase mode?) to achieve a watertight vase.

Any comments or clues would be greatly appreciated by makers that have found the “magic settings” for Creality Print or Orca Slicer with a K1 Max. I am tired of Wax coating the inside and using silicone sealant to achieve a watertight vase.

Hi MemCB, just checking, I see no one responded to your post and I would like to understand whether you solved your watertightness challenges? I am very much a newbie when it comes to printing, and I am playing around with water bottles on my K1 Max, which all leak. I’ve seen some YouTubers talk about upping flow rate and stuff, but I haven’t worked out the settings via Creality Print v6. Any tips would be appreciated.
Thanks in advance Data_Joe

Hi Joe;
I really didn’t get any foolproof solutions, but have had success with using PETG and printing in Spiral (VASE) Mode on vases and water pitchers, but have had to generally waxed (melted parefin wax) the inside or coated with a thin layer of silicone sealant. To get a waterproof vase without wax, I had to print with lultiple outer inner and outer layers which took a long time and used a lot of material. I have not tried water bottles. Sorry I could not offer a better solution, but good luck. Someone out there may have answers.
