The Stratasys F170 is the entry point to the F123 Design Series — industrial fused filament fabrication (FFF) built for reliability in office, lab, and classroom environments. It shares the same motion platform, heated build chamber, and GrabCAD Print software ecosystem as the larger F370, but packages it in a 254 mm cubic build envelope sized for individual prototyping workstations. Where a prosumer desktop printer asks the user to manage bed leveling, support generation, and material calibration manually, the F170 automates all three: auto-calibration runs before every job, QSR soluble support dissolves in an agitated bath, and GrabCAD Print reads native CAD files with preset material profiles tuned by Stratasys for each qualified filament.

What makes the F170 an industrial machine rather than a high-end desktop printer?

Four architectural decisions separate it from the prosumer tier. First, motion control: servo motors drive precision ball screws through linear profiled rails with recirculating ball bearings — not belt-driven open-loop steppers. The result is ±0.2 mm dimensional accuracy with a surface finish that requires no post-processing for functional prototypes. Second, thermal management: the fully enclosed, insulated steel-and-aluminum chamber with tempered glass door maintains a stable build temperature across the entire 254 mm cube, preventing the corner-lifting and interlayer delamination that plague open-frame printers with ABS and ASA. Third, soluble support: the dedicated QSR support extruder prints a breakaway/soluble material that dissolves completely in a heated sodium hydroxide agitation bath — no knife, no pliers, no scarring the part surface. Fourth, safety redundancy: door interlock sensors, thermal run-away protection, and voltage monitoring shut down motion and heaters if any parameter exceeds its safe operating window — a requirement for unsupervised operation in educational and professional settings.

How does the GrabCAD Print workflow differ from conventional slicing?

GrabCAD Print imports native CAD files — SolidWorks, Creo, NX, CATIA, Inventor, plus STL and VRML — without intermediate file conversion. Damaged or non-manifold geometry is auto-repaired on import. Material selection, layer height, infill density, and support strategy are chosen from pre-configured profiles rather than manually tuned parameter lists; Stratasys qualifies each material-layering combination and bakes the settings into the profile, so an engineer switching from ABS to PC-ABS selects the material from a dropdown rather than adjusting extrusion multiplier, retraction distance, and fan speed by trial and error. The software also supports Draft mode, which doubles print speed at roughly two-thirds material consumption by increasing layer height and widening extrusion width — useful for concept-validation iterations where surface finish is secondary to turnaround time.
