SPLA Print Parameter Test and Config file - Improved

prusaprinters

<p>Previously I posted a config file for use with print SPLA :</p><p><a href="https://www.prusaprinters.org/prints/65005-spla-print-parameter-test-and-config-file">https://www.prusaprinters.org/prints/65005-spla-print-parameter-test-and-config-file</a></p><p>While that configuration file works, it did have some problems with stringing. &nbsp;With more experimentation, I have found that I can print at lower temperatures and get good results. I also adjusted some of the retraction parameters. I was not able to eliminate stringing completely, but I did get considerable improvement.</p><p>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).</p><p>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.</p><p>Additional information here :</p><p><a href="https://www.sunlu.com/products/spla-1-75mm-filament-1kg-2-2lbs-fit-most-fdm-3d-printer">https://www.sunlu.com/products/spla-1-75mm-filament-1kg-2-2lbs-fit-most-fdm-3d-printer</a></p><h4>Installing</h4><p>To install the config file:</p><ul><li>&nbsp;download the file.</li><li>open PrusaSlicer</li><li>select File &gt; Import &gt; Import config . . .</li><li>select the downloaded config file</li></ul><p>If you previously installed my earlier version of this config file, you can just follow the instructions above, close PrusaSlicer, and then save the new settings.</p><h4>&nbsp;</h4><h4>Print Instructions</h4><p>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.</p><p>Use the provided gcode to print an XYZ calibration cube.&nbsp;</p><p>Import the included config-SPLA-215.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.&nbsp;</p><p>As before. while this configuration file works well for me, there is likely still room for improvement and I invite people to offer suggestions in the comments.</p><p>For testing this configuration file, I used this test print :</p><p><a href="http://www.thingiverse.com/thing:2975429">http://www.thingiverse.com/thing:2975429</a></p><p>&nbsp;</p>
