A system and method of additively manufacturing a part including electrically conductive or static dissipating fluorine-containing polymers. The method includes depositing fluorine-containing polymer additive manufacturing material onto a build platform, selectively cross-linking portions of the deposited additive manufacturing material, and curing the selectively cross-linked portions such that the part is at least one of electrically conductive and static dissipating.

A substrate holder for a lithographic apparatus has a main body having a thin-film stack provided on a surface thereof. The thin-film stack forms an electronic or electric component such as an electrode, a sensor, a heater, a transistor or a logic device, and has a top isolation layer. A plurality of burls to support a substrate are formed on the thin-film stack or in apertures of the thin-film stack.

A build plate for a three-dimensional printer includes: a rigid, optically transparent, gas-impermeable planar base having an upper surface and a lower surface; 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 positioned on the base upper surface. The build plate includes a gas flow enhancing feature configured to increase gas flow to the build surface.

A device for the laser-assisted processing of a material adhering to a substrate or a body that is associated with, or free of, a substrate or of its surface, in particular by TPA/MPA and/or by treatment with an ultrashort pulse laser. A sample holder of a positioning system holds the material to be processed. A laser source emits laser pulses or laser pulse sequences. Focusing optics shape the laser pulses or laser pulse sequences to impinge in a focal point or a focal volume in the region of the material or body to be processed so that a 2- or multi-photon polymerization can take place there, or in that they impinge in a focal point or in a focal volume in the region of the body in such a way that material located there or focal volume is subjected to the desired chemical and/or physical changes.

An object holder for a lithographic apparatus has a main body having a surface. A plurality of burls to support an object is formed on the surface or in apertures of a thin-film stack. At least one of the burls is formed by laser-sintering. At least one of the burls formed by laser-sintering may be a repair of a damaged burl previously formed by laser-sintering or another method.

The present application discloses a display panel, a manufacturing method of a display panel and a mask used thereof. The manufacturing method of the display panel comprises the following steps: doping a photo-initiator in photoresist for manufacturing photo spacers; coating the photoresist on the substrates to form photo spacers, and arranging a shade on the same layer; and respectively irradiating corresponding photo spacers by at least two types of light rays of different wavelengths, to control the photo-initiator so as to enable different photo spacers to have different shrinkages.

A three dimensional printing system includes a vertical support, a support plate, a resin vessel, a fluid spill containment vessel, and a light engine. The support plate is affixed to the vertical support at a proximal end. The support plate has an inner surface defining a first central opening. The resin vessel is supported above the support plate and has an inner edges surrounding a second central opening. The resin vessel includes a transparent sheet that closes the second central opening. The fluid spill containment vessel is supported below the support plate and includes a transparent window. The light engine is supported below the fluid spill containment vessel. The first central opening, the second central opening, and the window laterally overlap to provide an optical path whereby the light engine can project light upwardly to a build plane in the resin vessel.

Three-dimensional printing methods and systems use a derived geometry and aligns anisotropic inclusions in any orientation at any number of discrete volumetric sections. Structural, thermal, or geometry-based analyses are combined with inclusion alignment computations and print preparation methods and provided to 3D printers to produce composite material parts that meet demanding geometric needs as well as enhanced structural and thermal requirements. In one example, optimal inclusion alignment vectors associated with a section of the object are calculated based on specifications for the object, segmenting a three-dimensional model of the object into layer slices, grouping each section within each layer slice having similar alignment vectors and combining the groupings and generating printing instructions for the object according to the grouped alignment vectors.

A cassette includes a light transmissive window through which a temporally and spatially modulated image is passed. The window has a bottom surface, as part of the cassette, or as a separate component which may be separately interchangeable in the apparatus, or a part of the apparatus. In some embodiments: (i) the window bottom surface comprises a convex surface or consists essentially of a convex surface (e.g., without additional optical structure associated therewith); (ii) the window bottom surface comprises a concave surface or consists essentially of a concave surface (e.g., without additional optical structure associated therewith); (iii) the window bottom surface has a diffraction grating or Fresnel lens thereon or operatively associated therewith; (iv) a combination of (i) and (iii); or (v) a combination of (ii) and (iii).

Dry stereolithography using solid thermoplastic photopolymer plates/sheets/films provides a new technique to make 3D printed objects. In this new additive manufacturing process, objects are built layer-wise using thermoplastic photopolymers and actinic radiation. The thermoplastic photopolymer compositions consist of a thermoplastic photopolymer layer sandwiched between a transparent flexible base without an anchoring layer and a release film. Uncrosslinked portions of the 3D printed object are removed by heat. Preferred method of radiation exposure is digital light processing (DLP).
