A three dimensional printing system includes a controller that is configured to (1) receive an incoming slice data array that defines an initial two dimensional object having an initial outer boundary; (2) process the incoming slice data array to define a simple outer boundary whereby if the object has two portions defining a channel therebetween, the channel is reduced or eliminated thereby reducing a perimeter of the outer boundary. In one embodiment the object is two objects. If the channel is defined between the two objects, then the processing merges the two objects. If the channel is a concave recess within one object, then the processing reduces the depth of or eliminates the concave recess.

A method of validating a regulated application by generating, on a local data processing system, an automated agent to oversee a validation process of the regulated application on the local data processing system regardless of a local or web-based nature of the regulated application.

Remote validation for regulated environments

An apparatus, system and method for providing a consumable level monitor for association with a content-filled consumable. The embodiments may include a sensing module suitable to sense the consumable level; and a communications module suitable for receiving the consumable level from the sensing module, and for communicating the consumable level to a user.

Apparatus, system, and method of providing a content level monitor

The embodiments are and include an apparatus, system and method for a liquid level monitoring dispenser for association with a liquid filled consumable. The apparatus, system and method may include: a receiver for receiving the consumable upon inversion thereof; at least one electrical contact within the receiver for communicative association with conductive strips on the consumable; a sensing module communicative with the at least one electrical contact and having associated therewith firmware for converting signals associated with the conductive strips and received at the electrical contact to an indication of the liquid level; a communications module for communicating the liquid level to at least a user display and over at least one network; a power module for powering at least the sensing module and the communications module; and at least one dispensing output in fluid communication with the consumable and capable of dispensing the liquid from the consumable to modify the liquid level.

Thermoplastic 3D objects are printed directly onto permeable materials with a high strength bond. The 3D object can be attached to the permeable material at one side where the bottom layer of the 3D object can be attached to the permeable material or alternatively, at an internal layer where portions of the 3D object are on opposite sides of the permeable material. In order to improve the adhesion of the 3D object to the permeable material, the bonding layer of the liquid thermoplastic material that is printed directly onto the permeable material can be deposited at modified 3D printer settings that can include a hotter than normal material deposition temperature. Additional build layers of the liquid thermoplastic material are printed on the bonding layer to complete the 3D objects.

System and method for 3D printing on permeable materials

A three dimensional printing system includes a resin vessel, a light engine, a movement mechanism, a fixture, and a controller. The resin vessel is for containing a photocurable resin and has a lower portion with a transparent sheet. The light engine is configured to selectively project radiation up through the transparent sheet and over a build plane. The fixture is coupled to the movement mechanism and has a lower face that faces the transparent sheet. The controller is configured to operate the light engine to solidify a particle trapping sheet proximate to the build plane thereby trapping particles that extend upwardly from the transparent sheet into the build plane.

Three dimensional printing system that automatically removes particles from build plane

Methods of 3D printing an object with reduced curl on at least one surface that contacts a print plate are described herein. For example, in some embodiments, a method of 3D printing an object comprises depositing build material to form a first layer of a 3D printed object and depositing build material in a predetermined pattern to form a first layer of a skirt in contact with the 3D printed object. Depositing build material to form the first layer of the skirt comprises 3D printing a first layer of a sidewalk that substantially surrounds at least a portion of a perimeter of the 3D printed object and 3D printing a first layer of a perforated interface between the sidewalk and the perimeter of the skirt.

Methods and devices for counteracting stresses during 3D printing

In one aspect, adhesives for use with a 3D printer are described herein. In some embodiments, an adhesive for use with a 3D printer comprises a first polymeric component comprising a poly(vinyl alcohol) and a second polymeric component. The poly(vinyl alcohol), in some embodiments, comprises amorphous poly(vinyl alcohol). In some embodiments, the second polymeric component comprises a water-soluble polymer. Further, in some embodiments, an adhesive described herein further comprises a solvent, a surfactant, and/or a preservative.

Adhesive for 3D printing

There is provided a support structure for use with 3D printing of objects from computer-aided designs. The support structures include fine points that contact the down-facing surfaces of the 3D object being printed in order to adequately support the 3D object while also being adapted for easy removal after the 3D print process is complete. The fine points are possible by controlling the operation of the dispenser to provide a precise amount of material in a precise location. The dispenser jumps from a first fine point to a second fine point by retracting the print material after the first fine point is printed and then moving the dispenser vertically relative to the first fine point before the dispenser is moved horizontally to the second fine point.

Support structures and deposition techniques for 3D printing

There is provided solid imaging methods and apparatus for making three-dimensional objects from solid imaging material. A tray with a film bottom is provided to hold solid imaging material that is selectively cured into cross-sections of the three-dimensional object being built. A coater bar is moved back and forth over the film to remove any uncured solid imaging material from a previous layer and to apply a new layer of solid imaging material. A sensor is provided to measure the amount of resin in the tray to determine the appropriate amount of solid imaging material to be added, from a cartridge, for the next layer. A shuttle, which covers the tray when the exterior door to the solid imaging apparatus is opened for setting up a build or removing a three-dimensional object, can also be used to move the coater bar and to selectively open one or more valves on the cartridge to dispense the desired amount of solid imaging material.
