This test model lets you compare the performance of filaments on your printer with difficult areas like overhangs, bridging, etcetera over a temperature range. In this timelapse you can see Ultimaker PLA Silver Metallic tested from 210˚ to 190˚ C on an Ultimaker 2+ 3D printer.
Curious to find that sweetspot on how to best print overhangs or bridges? Give this stress test a go!
Thank you @UltiArjan!
