A filament drive for an extruder for an additive manufacturing system is provided. A drive gear is driven by a motor. A first driven gear is operably driven by the drive gear. A first hob has a toothed outer periphery connected to the first driven gear. A second driven gear is operably driven by the drive gear. A second hob has a toothed outer periphery connected to the second driven gear. The toothed outer peripheries of the first and second hobs define a filament receiving zone therebetween. A filament extruder including a heating element operated at greater than 48 volts may be provided.

Couplings between driven shafts of an actuator and a motor of an actuator are provided. The coupling may be directly integrated into a rotor of the motor. The coupling may be provided by an adaptor that includes a shaft that extends into a central bore of the rotor of the motor. The adaptor can include a collar that defines a coupling recess that receives a distal end of the driven shaft of the actuator. The collar may take the form of a clamp.

Motor with integrated coupler

A linear guide including a guide rail, a carriage, a drive screw and a connection arrangement is provided. The guide rail defines a linear travel path. The carriage is mounted to the guide rail for motion along the linear travel path. The drive screw is operably mounted to the guide rail. The connection arrangement couples the drive screw to the carriage to convert rotary motion of the drive screw to linear actuation of the carriage along the linear travel path. The connection arrangement provides a single degree of linear freedom between the drive screw and the carriage in a direction that is generally perpendicular to the linear travel path. The single degree of linear freedom permits relative motion between the screw and the carriage to relieve internal binding between the relative components.

Floating nut and carriage assembly

A linear slide is provided. The linear slide includes a guide rail, a carriage arrangement and a drive mechanism. The carriage arrangement includes a sidecar or nut arrangement for engagement with a screw of the drive mechanism. The nut arrangement is laterally offset from a carriage of the carriage arrangement.
