You can print S-PVA at high temperatures. It is recommend to heat the bed up to 80 °C and facilitate the adhesion to the bed with spray or glue. Set the cooling fans between 0 and 70%.
Suggested printing speed: 30-40mm/s.

The S-PVA maintains its performance in high temperature environments (up to 60 °C) but easily dissolves in warm water even if slower than other PVAs. To speed up the process, heat the water up to 40 °C. Moving water can also dissolve S-PVA faster.

To preserve the filament, keep away from humidity and sunlight. For better results, use the filament within 3-4 weeks after opening.

Due to all the different types of hot-end it's extremely difficult to give a temperature advice. Please consider our tips as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
