Medical devices, such as implants, and corresponding methods of manufacturing using an additive manufacturing technique, wherein the finished medical devices include a build plate retained therein, are disclosed. In some embodiments, the medical device includes a build plate having a plurality of peaks and a plurality of indentations, the plurality of peaks and the plurality of indentations together defining a surface roughness of an exterior surface of the build plate. The medical device may further include a first layer formed atop the exterior surface of the build plate, the first layer comprising a plurality of powder structures disposed over the plurality of peaks and the plurality of indentations. In some embodiments, an average peak distance between adjacent peaks of the plurality of peaks is less than an average width dimension of at least a portion of the plurality of powder structures.

Processes for manufacturing surface elements are disclosed. The surface elements can comprise a decorative upper layer and a supporting core. Processes for manufacturing such surface elements can comprise obtaining a decor at least by digitization of a number of archetypes selected from woods and minerals by making a high resolution digital picture of said archetypes, storing said decor digitally, manufacturing a plurality of supporting cores, each being of rectangular shape and each having a size essentially equaling only one desired end user format and provided with an upper side and a lower side, editing said decor to fit said shape and size of each one of said plurality of supporting cores, and digitally applying different patterns on each of said plurality of supporting cores, wherein said patterns are selected and parted from said decor and said decor is used to control said digitally applying the different patterns.

The invention relates to a separator material (6) for forming a separator for a lead-acid accumulator, especially in the form of unfinished rolled product, and a method for the production thereof. The inventive separator material (6) comprises a first layer in the form of a microporous film (1) and at least one second layer in the form of a planar fleece material (7). At least one face of the microporous film (1), which is made of a thermoplastic material, is provided with a number of protrusions (2, 2) defining an area with an increased film thickness on a basic film sheet. The fleece material (7) is welded to the film (1) by means of ultrasonic welding in such a way that the planar fleece material (7) is located at least at the level of the surface of the basic film sheet without invading the same in the area of the welded joints (8).

Processes for manufacturing surface elements are provided. The surface elements can include a decorative upper layer and a supporting core. Processes for manufacturing such surface elements can comprise manufacturing a supporting core having a format essentially equaling the desired end user format and provided with an upper side and a lower side, providing a ground coating on the supporting core, and applying a digitally printed dcor comprising inks of at least four colors directly on top of the ground coating by means of an ink-jet type printer, said four colors comprising one or more colors different from cyan, magenta, yellow and black; said digitally printed dcor being one of wood or mineral, and providing and curing an at least partly translucent wear layer on the upper side of the supporting core.

Processes for manufacturing surface elements are provided. The surface elements can comprise a decorative upper layer and a supporting core. Processes for manufacturing such surface elements can comprise manufacturing a supporting core having an upper side, treating said upper side of said supporting core, including at least one of the steps of ground coating with a primer, sanding and providing said upper side with a surface structure, applying a digitally printed dcor comprising inks of at least four colors directly on top of the ground coating by an ink-jet type printer, said digitally printed decor being one of wood or mineral, and providing and curing a protecting and at least partly translucent wear layer on the upper side of the supporting core.

A grooved resin molded part which when joined to another molded part, can form a composite molded product having an enhanced strength. This part contains an inorganic filler and has multiple grooves formed by partially removing the resin, such that the filler is exposed in these grooves. The depth of the grooves may be at least one-half of the length of the grooves in the shorter direction. The filler may have a fibrous shape; and the longer direction of the filler may be different from that of the grooves. The part is obtained by subjecting a resin molded part containing the filler to laser irradiation or the like to form multiple grooves in which the filler is exposed.
