Complex devices sometimes benefit from common sense solutions. FFF type 3D printers work best when the filament/build material initially sticks properly onto the build surface. Also, when the print is done it should be easily removed. A simple and extremely affordable solution is glue stick. After extensive testing, Creative Tools now offers the right type of glue stick for the purpose in our web shop, where you of course buy your FFF type 3D printers as well as filament.
