The important thing to know is that it's more of a semi-flexible material. This means it feels like hard rubber and doesn't flex much (also depends on what filler you use). This can be for or against, depending on the intended use. I have an Ender 3 with Direct Drive mod. EDIT 2: I've been printing with this filament for quite some time and I'm blown away by the quality of my prints. Layers look perfect, prints are durable and beautiful. I just had to log into my Cura profile. I get much nicer prints with this filament than with any of my PLAs! If you are looking for a semi-flexible yarn, this is definitely for you! Just unbelievable. EDIT: Updated my review. After a whole lot of profile tweaking and research, I managed to print it just fine! Now I'm printing it with a 200 hot end, no heated bed and at a speed of 30mm/s and a flow rate of 110%. .Taps should be kept to a minimum, but not completely disabled. When I turned off the retract, it was very difficult for me to remove the strings. After switching to these settings, my stand was almost perfect and I definitely recommend this thread if you use it for practical parts and not flexible parts. .I̶ ̶p̶r̶i̶n̶t̶e̶d̶ ̶a̶t̶ ̶1̶9̶5̶ ̶h̶o̶t̶e̶n̶d̶,̶ ̶5̶0̶ ̶b̶e̶d̶,̶ ̶a̶n̶d̶ ̶2̶5̶ ̶m̶m̶/̶s̶ ̶p̶r̶i̶n̶t̶ ̶s̶p̶e̶e̶d̶.̶ ̶G̶e̶t̶t̶i̶n̶g̶ ̶t̶o̶ ̶p̶r̶i̶n̶t̶ ̶w̶i̶t̶h̶ ̶i̶t̶ ̶w̶a̶s̶ ̶a̶ ̶b̶i̶t̶ ̶o̶f̶ ̶a̶ ̶c̶h̶a̶l̶l̶e̶n̶g̶e̶,̶ ̶a̶n̶d̶ ̶i̶t̶ ̶t̶e̶n̶d̶s̶ ̶t̶o̶ ̶u̶n̶d̶e̶r̶e̶x̶t̶r̶u̶d̶e̶ ̶o̶n̶ ̶o̶v̶e̶r̶h̶a̶n̶g̶s̶ ̶a̶n̶d̶ ̶b̶r̶i̶d̶g̶e̶s̶.̶ ̶I̶ ̶p̶r̶i̶n̶t̶e̶d̶ ̶a̶ ̶c̶a̶l̶i̶b̶r̶a̶t̶i̶o̶n̶ ̶c̶u̶b̶e̶ ̶a̶n̶d̶ ̶i̶t̶ ̶c̶a̶m̶e̶ ̶o̶u̶t̶ ̶a̶l̶m̶o̶s̶t̶ ̶p̶e̶r̶f̶e̶c̶t̶ ̶l̶o̶o̶k̶i̶n̶g̶,̶ ̶e̶x̶c̶e̶p̶t̶ ̶i̶t̶ ̶h̶a̶s̶ ̶a̶ ̶g̶a̶p̶ ̶b̶e̶t̶w̶e̶e̶n̶ ̶t̶h̶e̶ ̶i̶n̶f̶i̶l̶l̶ ̶a̶n̶d̶ ̶w̶a̶l̶l̶s̶ ̶o̶n̶ ̶t̶h̶e̶ ̶f̶i̶r̶s̶t̶ ̶l̶a̶y̶e̶r̶.̶ ̶T̶h̶e̶ ̶b̶e̶n̶c̶h̶y̶s̶ ̶I̶ ̶p̶r̶i̶n̶t̶e̶d̶ ̶w̶o̶u̶l̶d̶ ̶l̶o̶o̶k̶ ̶p̶e̶r̶f̶e̶c̶t̶,̶ ̶b̶u̶t̶ ̶(̶o̶n̶l̶y̶)̶ ̶t̶h̶e̶ ̶p̶l̶a̶c̶e̶s̶ ̶w̶h̶e̶r̶e̶ ̶t̶h̶e̶r̶e̶ ̶a̶r̶e̶ ̶o̶v̶e̶r̶h̶a̶n̶g̶s̶ ̶o̶r̶ ̶b̶r̶i̶d̶g̶e̶s̶ ̶( ̶s̶u̶r̶f̶a̶c̶e̶ ̶t̶h̶a̶t̶'̶s̶ ̶o̶n̶ ̶i̶n̶f̶i̶l̶l̶ ̶a̶s̶ ̶w̶e̶l̶l̶)̶ ̶h̶a̶v̶e̶ ̶s̶e̶v̶e̶r̶e̶ ̶u̶n̶d̶e̶r̶ ̶e̶x̶t̶r̶u̶s̶i̶o̶n̶,̶ ̶w̶h̶i̶c̶h̶ ̶s̶e̶e̶m̶s̶ ̶t̶o̶ ̶b̶e̶ ̶t̶h̶e̶ ̶b̶i̶g̶g̶e̶s̶t̶ ̶s̶t̶ r ̶u̶g̶g̶l̶e̶ ̶o̶f̶ ̶t̶h̶i̶s̶ ̶f̶i̶l̶a̶m̶e̶n̶t̶.̶ ̶ ̶T̶h̶a̶t̶ ̶s̶a̶i̶d̶,̶ ̶I̶ ̶h̶a̶v̶e̶n̶'̶t̶ ̶t̶r̶i̶e̶d̶ ̶u̶s̶i̶n̶g̶ ̶s̶u̶p̶p̶o̶r̶t̶s̶ ̶y̶e̶t̶,̶ ̶a̶n̶d̶ ̶w̶i̶l̶l̶ ̶p̶r̶o̶b̶a̶b̶l̶y̶ ̶u̶p̶d̶a̶t̶e̶ ̶t̶h̶e̶ ̶r̶e̶v̶i̶e̶w̶ ̶o̶n̶c̶e̶ ̶I̶ ̶d̶o̶.̶ ̶T̶h̶i̶s̶ ̶f̶i̶l̶a̶m̶e̶n̶t̶ ̶s̶h̶o̶u̶l̶d̶ ̶b̶e̶ ̶v̶e̶r̶y̶ ̶u̶s̶e̶f̶u̶l̶ ̶f̶o̶r̶ ̶p̶r̶i̶n̶t̶s̶ ̶t̶h̶a̶t̶ ̶r̶e̶q̶u̶i̶r̶e̶ ̶i̶m̶p̶a̶c̶t̶ ̶r̶e̶s̶i̶s̶t̶a̶n̶c̶e̶,̶ ̶a̶n̶d̶ ̶I̶ ̶w̶i̶l̶l̶ ̶p̶r̶o̶b̶a̶b̶l̶y̶ ̶u̶s̶e̶ ̶i̶t̶ ̶a̶ ̶l̶o̶t̶ ̶f̶o̶r̶ ̶p̶r̶a̶c̶t̶i̶c̶a̶l̶ ̶p̶a̶r̶t̶s̶.̶ ̶C̶o̶n̶s̶i̶d̶e̶r̶i̶n̶g̶ ̶t̶h̶e̶ ̶r̶e̶l̶a̶t̶i̶v̶e̶l̶y̶ ̶c̶h̶e̶a̶p̶ ̶p̶r̶i̶c̶e̶,̶ ̶I̶ ̶a̶m̶ ̶q̶u̶i̶t̶e̶ ̶s̶a̶t̶i̶s̶f̶i̶e̶d̶ ̶w̶i̶t̶h̶ ̶T̶he̶ ̶r̶e̶s̶u̶l̶t̶s̶ ̶i̶ ̶g̶o̶t̶ ̶s̶o̶ ̶f̶a̶r̶, ̶ ̶an̶d̶ ̶ w̶i̶l̶ ̶k̶e̶p̶ ̶t̶r̶y̶n̶g̶ ̶t̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶p̶ - i̶m̶i̶z̶e̶ ̶m̶y̶ ̶p̶r̶o̶f̶i̶l̶e̶ ̶f̶o̶r̶ ̶p̶r̶i̶n̶t̶i̶n̶g̶ ̶w̶i̶t̶h̶ ̶i̶t̶.̶
