I'm relatively new to the whole 3D printing community, but I have done a lot of research. Stumbled across Gulfcoasts page, and I haven't looked back!
This PEI plate practically sucks the filament out of the nozzle! I am able to print PLA, PETG, Nylon (blend), and ASA without any adhesives (glue, hairspray, etc) and often without any adhesion type (skirt/brim). And, the flex plate means I get to keep my magnetic bed from my Ender 3 Pro and use this right out of the box.
Great product! Highly recommend this for all of your printing needs!
