1cm3 test piece, 10.01x10.00x9.89 (mm) (XYZ), weight 1.19g. Density = 1.202g/cm3
Temperature: This printed relatively well across its range although the upper temperatures were giving better results, there was evidence of stringing at all temperatures, and lacking definition at the lower range.
Speed: The normal print speed of 45-50mm/s gives good results.
Volumetric Flow: Although it manage to print out the flow test piece to 10mm3/s, above 5mm3/s started to show signs blurring although interlayer bonding didn’t fail until 10mm3/s.
Preferred settings: For this PLA I preferred a temperature of 215°C and a print speed of 45mm/s.
Ultimaker Robot: A reasonable print, handling the overhangs and bridging reasonably well, some evidence of slight blobbing.
Tree Frog: Again a reasonable print although showed signs of slight blobbing and stringing between the front legs and at the retraction points.
3DBenchy: Benchy again showed stringing all over and some slight blobbing.

*As the vertical height can be effected by the distance of the bed-levelling to the nozzle the height of the “Top of the Chimney to the top of the box” should be more accurate for the comparisons
Conclusion: All the prints are from standard G.code files used for all the filaments to compare different filaments on the same print settings before any tweaking. Overall I would not rate this as one of the better PLA’s, I was not able to find the details for it on Polymaker’s web site for the datasheet etc. including colours available. The sample length did not allow for full testing of retraction settings but was not an ideal filament, if it is just Polymakers own PLA then there are better PLAs on the market.
Testing performed on an Ultimaker2, With a BondTec Feeder, a Matchless Block running a 35W heater and using a 0.4mm nozzle.
