Bioresorbable polymeric tubes suitable for use in a stent have been produced by a using a die drawing technique, comprising: deforming an orientable, thermoplastic polymer tubing (4) in the solid phase by drawing it over a mandrel (1) and/or through a die (3), where the mandrel (1) has a lead end and an exit end and the die (3) has an entry side and an exit side, wherein a drawing mechanism applies a drawing tension to the tubing (4) from the exit end of the mandrel (1) and/or the exit side of the die (3), said tension being insufficient to cause tensile failure of the tubing but sufficient to deform the tubing, thereby drawing the tubing over the mandrel (1) and/or through the die (3) in the solid phase to induce uniaxial or biaxial orientation of the polymer; and collecting the deformed tubing from the exit end of the mandrel (1) and/or the exit side of the die (3).

A system and method for forming 3D printed structures includes printing an outer shell portion and filling an interior of the outer shell portion to form an inner portion. The outer shell portion and inner portion may have differing material properties. The outer shell portion may be anchored to the base component.

A head is disclosed for use with a manufacturing system. The head may have a housing that discharges a tubular structure, and a cure enhancer connected to the housing and selectively activated to cure the tubular structure during discharge from the housing. The head may also have a nozzle that discharges a fill material into the cured tubular structure.

A spinner apparatus for applying lining material to the interior of a pipe, the spinner apparatus having a cylindrical material accelerator coaxially positioned about a distribution manifold, the distribution manifold having a plurality of equally spaced, radially oriented slots extending from an axial chamber that receives lining material, wherein lining material is extruded through the slots onto the interior of the material accelerator and slung onto the pipe interior in an annular pattern. Movement of the spinner apparatus along the pipe produces a tubular lining member.

A head is disclosed for use with a continuous manufacturing system. The head may have a housing, a fiber guide rotatably disposed at least partially inside the housing, and a diverter disposed at an end of the housing. The diverter may be configured to divert radially outward a matrix-coated fiber passing through the fiber guide.

A system and method for forming 3D printed structures includes one or more anchor portions on a base component. Additional materials can be printed on or adjacent to the anchor portions to provide additional structural components bonded to the anchor portions. These structures can be printed on, and can be a part of, a base component of an article of apparel.

A head is disclosed for use with a continuous manufacturing system. The head may have a housing configured to receive a matrix and a continuous fiber, and a diverter located at an end of the housing. The diverter may be configured to divert radially outward a matrix-coated fiber. The head may also include a cutoff having an edge configured to press the matrix-coated fiber against the diverter.

Disclosed herein is a method for producing insulated pipes having an improved protection of the insulation material. The pipe system comprises an inner pipe with a longitudinal axis extending from a first end of the inner pipe to a second end of the inner pipe, the inner pipe comprising a middle section, a first end section at the first end of the inner pipe, and a second end section at the second end of the inner pipe, a layer of inner coating covering the inner pipe, the layer of inner coating comprising one or more inner coating sub layers, one or more layers of insulation material covering the layer of inner coating such that the insulation layer covers the middle section of the inner pipe covered by the inner coating, and the ends of the insulation layer tapers towards the end sections, and the end sections comprises a section with an exposed layer of inner coating.
