A laser machining method performing cutting machining to cut a composite material over a thickness direction thereof by applying a laser beam to the composite material. The method includes applying the laser beam from one side in the thickness direction of the composite material so as to form a first cutout in the composite material; and applying the laser beam from the other side in the thickness direction of the composite material, forming a second cutout in the composite material at a position opposing the first cutout, connecting the second cutout to the first cutout, and cutting the composite material. The first cutout is formed by applying the laser beam through a plurality of machining paths arranged in the width direction of the first cutout. The second cutout is formed by applying the laser beam through a plurality of machining paths arranged in the width direction of the second cutout.

Another molded article comprising the other material is arranged surrounding the fibrous inorganic filler in the insides of the grooves.

Device surfaces are rendered superhydrophobic and/or superoleophobic through microstructures and/or nanostructures that utilize the same base material(s) as the device itself without the need for coatings made from different materials or substances. A medical device includes a portion made from a base material having a surface adapted for contact with biological material, and wherein the surface is modified to become superhydrophobic, superoleophobic, or both, using only the base material, excluding non-material coatings. The surface may be modified using a subtractive process, an additive process, or a combination thereof. The product of the process may form part of an implantable device or a medical instrument, including a medical device or instrument associated with an intraocular procedure. The surface may be modified to include micrometer- or nanometer-sized pillars, posts, pits or cavitations; hierarchical structures having asperities; or posts/pillars with caps having dimensions greater than the diameters of the posts or pillars.

Methods capable of forming holes in, etching the surface of, or otherwise ablating substrates, and substrates formed thereby. A first method includes directing a first laser beam pulse towards a substrate to form a hole in a surface thereof and to form a plasma plume at least partially within the hole wherein the plasma plume has insufficient thermal energy and expansion velocity to etch sidewall of the hole, and directing a second laser beam pulse into the plasma plume to increase the temperature and expansion velocity of the plasma plume such that the sidewall is etched causing an increase in the cross-sectional dimension of the hole. A second method includes applying a liquid to a surface of a substrate, and directing a laser beam pulse into the liquid to create plasma on the surface of the substrate that etches portions of the surface of the substrate.

A method and an apparatus of forming a three-dimensional object, wherein the method includes providing a carrier and an optically transparent member having a build surface, said carrier and said build surface defining a build region therebetween; filling said build region with a polymerizable liquid, continuously or intermittently irradiating said build region with light through said optically transparent member to form a solid polymer from said polymerizable liquid, continuously or intermittently advancing (e.g., sequentially or concurrently with said irradiating step) said carrier away from said build surface to form said three-dimensional object from said solid polymer, said optically transparent member comprising a build plate for a three-dimensional printer comprising: an optically transparent first channel layer; an optically transparent, gas permeable second channel layer on the first channel layer; and a flexible, optically transparent, gas-permeable sheet having an upper and lower surface, the sheet upper surface comprising a build surface for forming a three-dimensional object, the sheet lower surface being positioned on the second channel layer.
