A solid imaging apparatus and method employing sub-pixel shifting in multiple exposures of the digitally light projected image of a cross-section of a three-dimensional object on a solidifiable liquid medium. The multiple exposures provide increased resolution, preserving image features in a three-dimensional object and smoothing out rough or uneven edges that would otherwise be occur using digital light projectors that are limited by the number of pixels in an image projected over the size of the image. Algorithms are used to select pixels to be illuminated within the boundary of each image projected in the cross-section being exposed.

Edge smoothness with low resolution projected images for use in solid imaging

The presently disclosed subject matter is directed to an apparatus for the preparation of a cleaning, sanitizing, or sterilizing solution. In some embodiments, the apparatus comprises a modular component, such as a cartridge. The cartridge may contain chemical precursors to allow the generation of chlorine dioxide. The apparatus has a fluid inlet, and separates the fluid into a first flow path, which fills a reservoir. It also has a second flow path, which is heated before passing through the cartridge to create the desired gas. The fluid output from the cartridge is then fed into the reservoir.

A method for making a foam-in-place cushion in which a foam-forming composition is dispensed between two plastic film portions in a predetermined fashion to selectively control the distribution of the foam in the cushion. A foam dispenser can be moved in a transverse direction as foam is dispensed. A dispersion device can be employed to apply pressure on predetermined areas of the film portions towards each other so as to cause the composition to be redistributed in position in a predetermined manner while the composition is in a less than fully expanded state. The plastic film can then be sealed closed to form an expanding foam cushion that can be placed into a shipping carton where the cushion expands to fill void space, or into a mold where the cushion expands and is molded into a desired shape.

A solid imaging apparatus is provided that includes a replaceable cartridge containing a source of build material and an extendable and retractable flexible transport film for transporting the build material layer-by-layer from the cartridge to the surface of a build in an image plane. An operator using the device needs merely to remove a spent cartridge and replace it with a fresh cartridge to continue solid imaging virtually uninterrupted. The apparatus also includes the capability of withdrawing and inserting an imager without the operator having to perform a separate alignment step. A brush attached to the transport film and forming part of the cartridge provides for intra-layer removal of excess uncured build material. If desired, the apparatus can produce a fully reacted build. A high intensity UV source cures the build between layers. An injection molded build pad is designed to hold a build in an inverted position for improving the build. The invention also provides for tilting the build elevator to reduce air entrainment and for releasing the build from the image plane.

An apparatus and method for cooking food, such as meat, protein, vegetable, or soup is disclosed. In one embodiment, the food items are supplied in a flexible polymer package that can withstand the temperature needed to cook the item. The cooking apparatus has two cooking surfaces in the form of heated platens, which may be arranged in a vertical orientation. These platens come together to simultaneously contact both sides of the food item. The cooking apparatus further includes a controller, configured to prepare the food using various control system algorithms. The apparatus cooks the food item from both sides to affect rapid and even cooking. It uses a combination of temperature, time, food thickness, platen force and a cooking code that is unique for each food type. The control system algorithm uses some or all of these parameters to determine precisely when the food item is cooked correctly.

A disposable liquid build material feed cartridge for use in a solid imaging apparatus and a method of dispensing build material for use in such an apparatus with a radiation transparent build material carrier. The disposable liquid build material feed cartridge recovers unused liquid material from the radiation transparent build material carrier and recycles it through a filter into a supply reservoir for reuse. A dispersing roller is employed to express any entrapping air bubbles in the solidifiable liquid build material that is dispensed onto the radiation transparent build material carrier prior to its being imaged.

An inflatable web, and method and apparatus for inflating the web, which generally includes two sheets having inner surfaces sealed to each other in a pattern defining a series of inflatable chambers of predetermined length, each of the chambers having at least one change in width over their length; an inflation port located at a proximal end of each chamber, the inflation ports being formed by intermittent seals between the sheets; and longitudinal flanges formed by a portion of each of the sheets that extend beyond the inflation ports and intermittent seals.
