Review on YOYI 3D Printer Filament - PETG 1.75Mm 2.2Lbs(1Kg) Spool, High Accuracy +/- 0.03 Mm, 100% New Raw Material! by Dave Moody

The Green filament can deliver good print quality with unexpectedly strong prints. This stuff will bend and stretch before breaking and it is very strong. First layer adhesion is critical and very difficult. This will not print easily on a stock monoprice maker select v2, but it prints well with a modified fan and a very well leveled bed. My best results are with .3mm first layer at 225C with a 67C bed, 40% cooling. Other layers 235C with a 65C bed, 100% cooling. You do not want the nozzle too close on the first layer or it will stick to the nozzle instead of the bed. Good value, if you're experience with 3d printing and have a good feel for your machine.
