SPLA Print Parameter Test and Config file

Edit May 1, 2021 : I suggest using the improved version of this:

SPLA is a filament type offered by SunLu. Although the name implies it is another type of PLA, it has printing properties very different from PLA or PLA+. SPLA requires higher extrusion and bed temperatures than PLA, and requires slower print speeds.

What exactly is SPLA? SunLu doesn't really say, but apparently the name comes from Shiny PLA because prints made with it have a glossy appearance. SunLu also claims the filament is stronger than PLA, and the colors are more intense (I have not tested these claims).

Initially I tried to print SPLA as if it was PLA, and got very poor results, and numerous print failures. With a bit of research I realized my mistake and created a revised print configuration based on a modified PETG configuration. With this new print configuration I am now getting very good results, and I invite others to test this configuration.

Print Instructions

I recommend using a textured build plate. A smooth build plate will work, but the cooled filament is very “sticky” and can be difficult to remove.

Use the provided gcode to print an XYZ calibration cube. 

Import the included config.ini file into your copy of PrusaSlicer for a configuration you can use to print other items. The configuration file includes the required settings for nozzle temperature, bed temperature, and print speeds.  While this configuration file works well for me, it is probably not 100% optimal and I invite people to offer improvements.

The calibration cube is from here:
