The Stratasys 821726-0001-S is the carbide Fortus 450mc printhead assembly—the hardened variant of the Fortus 450mc head (blue handle)—designed for use in Stratasys Fortus 450mc industrial FDM printers. Identified in Stratasys catalogs as ASSY, HEAD 450MC CARBIDE, this replacement head carries the 821726-0001-S designation and is built to endure wear in demanding extrusion applications. Compatible with Fortus 450mc systems, it preserves the core extrusion function of the Fortus head while employing carbide construction for increased wear resistance within the Fortus 450mc printhead family.
