Filament Swatch for REGEN PHA Quicksand.

I've include calibrated filament and print profiles.

I read about PHA a couple months back and thought I'd try it out. At the time this brand was the only one readily available from the US. There are a couple other brands I plan on trying later. It has taken me a number days of tweaking to get settings to the point where I could print a passable benchy. This material is quite tough to work with and attempts to contact REGEN and filaments.ca for assistance have yielded nothing.

If you're using Bambu Studio, you have to either manually configure the pressure advance for the entire printer or add the provided gcode to the Custom Filament Start gcode. Look for the REGEN PHA - Quicksand - PA Override.txt

The big thing is this PHA wants to be printed slow. My print settings also attempts to reduce print artifacts from rapid speed changes. I still have some artifacts on overhangs 45% or higher and there's more tuning that can be done with flow as the benchy hull line is quite prominent. The short bridges in the benchy are somewhat passable. I've tried some longer bridges and they still aren't very good.

I'll update this as I find ways to improve it. Please let me know if you figure out anything and I'll update the profiles if I can reproduce it.

My settings are free to use so long as you don't try to sell the settings for whatever reason.

I'm learning and having fun with this. Feedback letting me know how your print went would be greatly appreciated.
