An additive three-dimensional fabrication process is improved by controlling deposition rate to obtain surface textures or other surface features below the nominal processing resolution of fabrication hardware. Sub-resolution information may be obtained, for example, from express metadata (such as for surface texture), or by interpolating data from a source digital model.

An artificial turf system comprises a resilient layer, an artificial grass layer comprising a substrate and pile fibers upstanding from the substrate and an infill layer. The infill layer comprises smooth, hard granules having a mean size of between 1.8 mm and 10 mm disposed on the substrate and interspersed between the pile fibers. The smooth, hard granules provide improved characteristics in terms of foot release.

Apparatuses and methods are provided for manufacturing a transaction card. The disclosed apparatuses and methods may be used to form a transaction card frame configured to house a data storage component. The card frame may be formed of a resin mixture comprising a thermoplastic elastomer (TPE). The card frame may also have a Shore D hardness in the range of 20-80.

A method of blow molding an article having at least one layer of thermoplastic material. The method comprises the steps of heating a mold having an inner surface with two or more areas of different surface textures to a first temperature of greater than 55 C. and subsequently feeding a parison into the mold. The parison is then blown against the inner surface of the mold to form an article. The temperature of the mold is subsequently lowered to a second temperature of between 20 C. to about 55 C. and the temperature cycle time (t.sub.ct) of the mold is less than 250 seconds. Using the two phase heating and cooling process in combination with a mold featuring different surface textures provides a finished article with different visual effects.

The invention relates to a polyethylene sealant film comprising an outer layer O, a core layer C and an inner layer I, wherein the core layer C is made of a core layer composition comprising a component AC, which is a recycled low density ethylene polymer in an amount of at least 50 wt. %, based on the total weight of the core layer composition, and a slip agent; and the inner layer I is made of an inner layer composition comprising a component AI, which is a linear low density ethylene polymer having a density of from 910 to 925 kg/m.sup.3 and an MFR.sub.2 of from 0.5 to 2.0 g/10 min. determined according to ISO 1133. The invention further relates to a laminated polyethylene film and article comprising this polyethylene sealant film. The invention further relates to the use of the laminated polyethylene film and/or the polyethylene sealant film for packaging of an article.

The invention relates to a method for producing a plastic component (1) having defined target dimensions, in particular defined target outer dimensions, said method comprising: forming a one- or multi-part base body structure (2) in an additive manufacturing process, wherein the base body structure (2) is formed with an undersize with respect to the defined geometric target dimensions, attaching at least one enveloping element (3) enveloping the base body structure (2) on the exposed surfaces of the base body structure (2) by forming the plastic component (1) that is to be produced, wherein an enveloping element (3) is used, the wall thickness of which compensates the undersize of the base body structure (2) with respect to the defined geometric target dimensions of the plastic component (1).

A photo-curable resin composition for three-dimensional shaping includes a polyfunctional radical polymerizable compound (A), a monofunctional radical polymerizable compound (B), polyethylene particles (C), and a curing agent (D). The polyfunctional radical polymerizable compound (A) is a single polyfunctional radical polymerizable compound having an ethylenically unsaturated group equivalent of 700 g/eq or more and 8,000 g/eq or less or a mixture including a plurality of types of polyfunctional radical polymerizable compounds and having an ethylenically unsaturated group equivalent of 700 g/eq or more and 8,000 g/eq or less, the ethylenically unsaturated group equivalent being a weighted average of ethylenically unsaturated group equivalents of the polyfunctional radical polymerizable compounds in terms of weight ratio. A content of the polyethylene particles (C) is 5 parts by mass or more and 50 parts by mass or less relative to 100 parts by mass of a total of the polyfunctional radical polymerizable compound (A) and the monofunctional radical polymerizable compound (B).

A method is provided for surface smoothing an additively manufactured shaped part consisting of plastic. The method has an explosion step with which the surface of the shaped part is smoothed in a process chamber by igniting a combustible process gas introduced into the process chamber, the surface of the shaped part being partly dissolved in at least some sections by the ignited process gas. Also provided is a device for surface smoothing additively manufactured shaped parts consisting of plastic.
