RADIATION AMOUNT DETERMINATION FOR AN INTENDED SURFACE PROPERTY LEVEL

According to examples, an apparatus includes a processor and a memory on which is stored machine readable instructions. The instructions may cause the processor to identify an intended surface property level for a surface of a three-dimensional (3D) object, determine an amount of radiation to be applied as a flash of radiation onto the surface to obtain the intended surface property level, and output the determined amount of radiation to be applied as a flash of radiation, in which a radiation source is to flash apply the determined amount of radiation onto the surface of the 3D object.

POROUS STAMP MATERIAL FOR LASER PROCESSING, POROUS STAMP USING THE SAME, AND METHOD OF MANUFACTURING THE SAME

The invention provides a porous stamp material for laser processing that is available for continuous extrusion molding. A material including at least 100 parts by weight of thermoplastic resin, 50-250 parts by weight of hydroxylated compound whose dehydration starting temperature is 100 to 500° C., and water-soluble pore-forming material that has 10-60 μm average particle diameter is mixed to obtain a mixed material. The obtained mixed material is extruded to obtain an extrusion molded product. The obtained extrusion molded product is processed with an aqueous solvent to elute the water-soluble pore-forming material, thereby yielding a porous stamp material that has continuous pores having 10-60 μm pore diameter. The obtained porous stamp material is laser-processed to manufacture a stamp.

COMPONENT WITH CUSTOMIZED EXTERIOR SURFACE AND METHOD OF MANUFACTURE

A component with a customized exterior surface and a method and tool for manufacturing the same are provided. The component may be formed via a plastic forming process with a forming tool, such that it has a surface texture formed on its exterior surface. The forming tool has at least one tool surface, which defines a mold cavity. The tool surface has a textured layer coupled thereto, such that the textured layer directly contacts a moldable material supplied to the mold cavity. The textured layer has a surface texture formed thereon resulting in the surface texture present on the textured layer being transferred to and formed on the exterior surface of the component during forming. The textured layer may be changeable or replaceable with respect to the at least one tool surface, such that a single tool may form components with different surface textures formed on the exterior surface thereof.

09744619 · 2017-08-29 · ·

Described herein are an apparatus and a method for direct engraving an elastomeric printing plate by multiple laser beams simultaneously. In one embodiment, an elastomeric printing plate or sleeve is positioned on an imaging drum for direct engraving. The imaging drum is rotatable around its longitudinal axis. Such rotation defines a circumferential direction, also called the transverse direction. The axis of rotation defines an axial direction, also called the longitudinal direction. The printing plate has an body and a surface made of an elastomer (made of polymer or rubber). A drive mechanism provides relative motion between a plurality of laser beams and the plate in both the transverse and longitudinal directions.
