A core mould element can be mounted between first and second mould parts. The first and second mould parts and the core mould element can be mounted between first and second thermal platens. The thermal platens can have generally planar faces for mounting in a press, for maintaining a desired pressure within the mould assembly. The thermal platens can provide for heating and cooling the mould assembly, and each can include a central portion and end portions, with thermal breaks between the central portion and the end portions. Bores can extend through the central and end portions, for receiving heating elements and pipes for cooling fluid. The end portions can include bores for a cooling fluid for cooling the end portions.

The invention relates to an improved blowing nozzle, in particular for stretching systems, which is characterised by the following features, inter alia: the nozzle box (5) is divided in its longitudinal direction (L) into at least two regions, specifically a first longitudinal region (LB1) closer to the inflow side (7) and a second longitudinal region (LB2) that is subsequent and/or downstream and/or further away from the inflow side (7), the first longitudinal region (LB1) is convergent or comprises at least one convergent portion in which the height (H) between the lower face (11) and the upper face (15) is smaller than the height (H1) in the region of the inflow side (7) as the distance from the inflow side (7) increases, and the second longitudinal region (LB2) is divergent or comprises at least one divergent portion in which the height (H) between the lower face (11) and the upper face (15) is greater than the height (H) at the end of the first longitudinal region (LB1) and/or at the beginning of the second longitudinal region (LB2) as the distance from the inflow side (7) increases.

Apparatus for facilitating automated removal of a printed part from a 3D printer's print bed includes a print surface applied to the print bed, wherein the print surface has properties which change with temperature, affecting adhesion to the printed part. Cycling the temperature of the print bed enables adhesion of the part to the print bed during printing and release of the part from the print bed upon completion of the print. The print bed may be oriented vertically or at an incline to the horizontal to enable gravitational forces to pull the printed part away from the print bed upon completion of the print. Peltier devices or other cooling mechanisms may be provided to facilitate cooling of the print bed for release of the part. In certain embodiments, the print bed is configured to provide mechanical part removal to automatically dislodge the printed part from the print bed.

Methods and systems are provided for ultra-violet curing, and in particular, for ultra-violet curing of optical fiber surface coatings. In one example, a curing device includes a first elliptic cylindrical reflector, with a second elliptic cylindrical reflector housed within the first elliptic cylindrical reflector. The first elliptic cylindrical reflector and second elliptic cylindrical reflector have a co-located focus, and a workpiece to be cured by the curing device may be arranged at the co-located focus.

A method for post-treating a three-dimensional object produced by selectively solidifying, layer by layer, of a building material in powder form and/or post-treating unsolidified building material in which the three-dimensional object is embedded. The three-dimensional object and/or the unsolidified building material may be treated with a liquid. The liquid may comprises a liquid carrier substance and at least one further substance that reduces surface tension of the carrier substance.
