Abstract: An additive manufacturing system and method for making components having filaments formed by elastomeric materials. A liner includes the filaments formed by an elastomeric material and is adapted for a prosthetic device system. The filaments form an elastomeric lattice structure and solid layers or features and define a ventilated structure permitting a transfer of air and moisture from an interior volume of the liner to an exterior or ambient liner. The liner may incorporate an adhesive and a textile layer secured to the elastomeric lattice structure and further define recesses and other features for improving a liner.

Abstract: A three-dimensional (3D) printing system (2) for manufacturing a 3D article includes a resin vessel (6), a build plate (8), a plate support (10), a hook subsystem (12), an elevator subsystem (14), an imaging subsystem (16), and a controller (20). The build plate has an upper surface and extends from a proximal end to a distal end. The hook subsystem includes a hook (46). The controller is configured to: (a) Operate the elevator subsystem and the imaging subsystem to fabricate the 3D article. (b) Operate the elevator subsystem to raise the 3D article above photocurable resin in the resin vessel. (c) Operate the hook subsystem to configure the hook to be engaged with the proximal end of the build plate. (d) Operate the elevator subsystem to impart a vertical separation distance between the proximal and distal ends of the build plate. The vertical separation distance defines an angular tilt of the 3D article to facilitate draining of residual photocurable.

Abstract: An example hose management apparatus can include an x-axis member extending along an x-axis. A plurality of trolley units can be slidably moveable along the x-axis member. The trolley units can include rotatable hose supports. A delivery hose can rest on the rotatable hose supports. The delivery hose can include an outlet that is moveable laterally with respect to the x-axis member, and the delivery hose can be frictionally engaged with the rotatable hose supports such that movement of the delivery hose causes the hose supports to rotate, thereby reducing a frictional force acting to hinder to the movement of the delivery hose. The apparatus can also include a vertical support system which suspends the x-axis member at a predetermined height above a ground surface.
