Argyle Break Away Support (BST) is a Plug & Play refill material (peel away, won't wash off) compatible with ABS, ASA and PC-ABS on F123® Stratasys® 3D Printers because it runs with the same parameters used for the Soluble support. BST is  faster & easier alternative to QSR® if you already peel awayand don't wash off support. It doesn't shatter and cut your hands like QSR does. Not recommended for trapped areas or blind holes. Our BST requires a fresh Support head, no other changes. Initial orders come with a chip holding spindle and spool feed canister that rests behind the machine. Filament feeds into the bowden tube above the Y junction. All spools come with an OEM chip and Dongle Repair Device (DRD) that co-mingle in the custom spindle which rests in the Support spool slot powered by User supplied USB cable. Note: save all OEM sindle chips and DRD for $5/ea return credit. This excellent alternative to OEM Support material requires no adjustments or recalibrations of your machine and will save 21% vs OEM. Fresh/dedicated Support tip/head required. See FAQ page for Material loading / installation instructions
