SR-20 Soluble Support no longer available from Stratasys. What are my options?

Stratasys is no longer selling SR-20 support, ostensibly to force companies to upgrade their Classic Fortus 400mc or 900mc machines. Argyle Materials to the rescue: we take the OEM handcuffs off.

AI will tell you Stratasys PC-ABS uses soluble support, but the exact support depends on the printer family:

F370 / F370CR: QSR Support
Fortus 450mc: SR-110
Fortus 900mc / F900: SR-110

There is also an older SR-20 canister listed in the PC-ABS ordering info for classic systems, which mainly applies to older Fortus 900mc configurations rather than current mainstream compatibility.

Therefore you can order QSR or preferably SR-110 to run on your classic Fortus machine. Just call us and we'll provide Classic eeprom chips for SR-20 which is what your machine is looking for. You remove the black OEM eeprom from the SR-110, remove plastic indexing tab, drill new chip pilot hole, replace with our Classic eeprom, send Plus chips from the SR-110 to Argyle in exchange for the classic chips.

Alternatively you can switch to our PC-ABS (its also flame retardant) and it prefers to run with an ABS-M30 eeprom which means you can run SR-30 Soluble Support or our Breakaway (HIPS) support using an SR-30 eeprom chip. By the way our Breakaway also works with OEM PC-ABS, offers faster support removal and much lower consumable cost; consider Breakaway if your parts have easily removed support.
