Lately I experimented with soft-PLA from Orbi-Tech and would like to share my (very useful) results with you:
The first prints were really bad. I couldn’t even load the filament. Because it is so soft, the Printer (in my case a Witbox) wouldn’t take it into the hotend. So my hotend was blocked several times.
So I decided to put the soft-PLA in the fridge for a night. The next day it worked marvellous.
For your slicer, I recommend the following options:
100% fill. Otherwise the layers won’t stick together very well. Smaller objects get perfectly flexible. Very solid objects tend to loose their flexibility because they are filles 100%
20mm/s printspeed. This way the soft-PLA gets applied carefully and the layers stick better together
235°C temperature. This will make the filament more liquid and it flows better trough the hotend.
125% flow makes the filament go smoothly trough the hotend.
I hope I could help you with your soft-PLA prints.
