Shaping method, slice data generating method, shaping device, and slice data generating device
A shaping method is provided and includes: generating a slice data indicating a cross-section of a shaped object based on a shaped object data, and shaping the shaped object. In a shaped object data preparing step, the shaped object data including multiple pieces of part data is prepared. Each piece of the part data is data indicating at least an outer surface shape of a portion indicated by the part data and a color to be colored on an outer surface. In the slice data generating step, the slice data indicating a cross-section of the shaped object is generated by setting the color of each position of the cross-section corresponding to a portion indicated by each piece of the part data, and a color of an interior of the portion indicated by each piece of the part data is set based on a color set for the outer surface.
Process for forming plastic corrugated container and intermediary blank
A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.
RESIN SLOT EXTRUDER FOR ADDITIVE MANUFACTURING SYSTEM
A slot extruder for use with an additive manufacturing system, which includes a plenum configured to receive a photocurable resin, an elongated slot positioned at a bottom end of the plenum and configured to receive the photocurable resin from the plenum, one or more resin inlet ports extending into the plenum, and one or more mechanisms configured to controllably pressurize and depressurize the photocurable resin in the plenum.
System and Method for Printing Tissue
A system and method for printing cells in a medium. A multi-dimensional printer, stably constructed of low-mass parts, can include a computer numerically controlled system that can enable motors driving delivery systems. The motors can include encoders that can enable achieving arbitrary resolution. The motors can drive ballscrews to enable linear motion of delivery systems, and the delivery systems can enable printing of a biological material in a pre-selected pattern in a petri dish. The petri dish can accommodate a medium such as a gel, and can further accommodate a vision system that can detect actual position and deflection of the delivery system needle. The printer can accommodate multiple delivery systems and therefore multiple needles of various sizes.

Additive manufacturing apparatus with a chamber and a removably-mountable optical module; method of preparing a laser processing apparatus with such removably-mountable optical module
An additive manufacturing apparatus comprises a processing chamber (100) defining a window (110) for receiving a laser beam and an optical module (10) The optical module is removably-mountable to the processing chamber for delivering the laser beam through the window. The optical module contains optical components for focusing and steering the laser beam and a controlled atmosphere can be maintained within the module.
Exposure device and exposure method
An exposure device includes a rotation driving section that rotationally drives an exposure object; a light irradiation section that irradiates an exposure surface of the exposure object with laser light; a slide moving section secured to the rotation driving section or the light irradiation section, and moving the rotation driving section or the light irradiation section along the exposure surface in a direction crossing a direction of rotation of the rotation driving section; a signal generating section that transmits an analog modulating signal to the light irradiation section in accordance with a rotation synchronization signal from the rotation driving section, the analog modulating signal causing an intensity of the laser light to be changed; and a controlling section that controls movements of the rotation driving section, the slide moving section, and the light irradiation section.
Mold material, molding method, mold object, and molding apparatus
A molding apparatus includes a heating section, a spreading section, a molding section, a drawing section and a curing section. The heating section which heats a mold material including particles and a binder agent which bonds together the particles, to a temperature equal to or higher than the melting point of the binder agent and forms a fluid mold material. The spreading section forms a mold layer by spreading the fluid mold material. The molding section layers the mold layers. The drawing section applies UV ink to a desired region of the mold layer. The curing section cures the UV ink applied to the desired region of the mold layer.
Removing sharp cusps from 3D shapes for additive manufacturing
A method for processing a three-dimensional (3D) mesh model includes receiving a 3D mesh model. One or more regions including a potential sharp cusp are automatically detected. The automatically detected one or more regions are displayed to a user and an active region of the 3D mesh model is defined by the user. Sphere fitting and Laplacian smoothing are applied to the designated active region to remove a sharp cusp therefrom and to obtain a modified 3D mesh model.
System and method for protection of printed images formed on surfaces of three-dimensional printed objects
A method of forming a three-dimensional printed object having a printed surface image includes ejecting drops of a build material to form the three-dimensional printed object from a plurality of layers of build material on a support member and applying a leveler to a surface of each layer of the build material. The method further includes ejecting drops of a marking agent on a surface of the three-dimensional printed object to form a printed image, ejecting drops of a transparent material over the printed image to form a layer of transparent material over the printed image, and applying the leveler to a surface of the layer of transparent material but not to the printed image.
