I have two here at work that I help maintain (MakerGear MkII & Fusion360 - we LOVE that one!!) The purple glue stick. that's what came with the Fusion360. works well, too well almost! We tried a sheet of plexi on the MkII (no heat though!) and worked OK.. We run PLA at 215°C & a bed at 70°C. that's what our PLA manuf. recommends. So far, no issues.
