Abstract: Computer-implemented methods (5000) for forming a fiber-reinforced composite device (500) comprising fiber-comprising tow(s) (100). Methods include forming (5100) a first preform model (1100) comprising one or more anisotropic tow layup portion (1010P) comprising fiber-comprising tow(s) (100); receiving (5110) one or more mold geometrical components; receiving (5130) one or more molding force vector parameters (8130); forming (5150) an intermediate device model (500ID) by deforming (5152) the first preform model (1100) against the mold geometrical component(s) (8100) using the molding force vector parameter(s) (8130); and forming (5200) a second preform model (1200). Forming (5200) the second preform model (1200) comprises adjusting (5250) the first preform model (1100) by forming (5150V) a tow layup adjustment vector (1150) comprising one or more vector extending from one or more tow (100) of the first preform model (1100) to one or more tow of the second preform model (1200) as a function of one or more position transformation vector (500IDV) extending from one or more tow (100) of the first preform model (1100) to one or more tow (100) of one or more intermediate device model (500ID).

Abstract: Filament feeding devices (3001) and method (5000), for guiding a filament (100) into an additive manufacturing apparatus (2000), the filament feeding devices comprising: a filament travel path (100TP); a filament buffer (3600) comprising a telescopic tubular assembly (3600A) comprising a filament entrance at a first end (3600A1) of the tubular assembly and a filament exit at a second end (3600A2) of the tubular assembly, the tubular assembly comprising: a first tube (3610) having a first tube longitudinal centerline (3610L); and a second tube (3620) comprising a portion (3620P) into which a portion (3610P) of the first tube (3610) is telescopically inserted; and a position sensor (3650); a controller (4110) connected to the position sensor (3650); and a computer-readable non-volatile storage device (4120), wherein the position sensor (3650) is configured for measuring a position (3650P) of the first tube (3610) with respect to a reference point.
