Abstract

A 3D printing system (2) includes a build plate (6) supporting a 3D article (4), a drop on demand piezo (DODP) printhead (10), a horizontal movement mechanism (14), a supply (12) of phase change ink, and a controller. The controller (20) is configured to: operate the supply (12) and the DODP printhead (10) to maintain a liquid state of the phase change ink, position an upper surface of the 3D article at a build plane, scan the printhead over the upper surface, and operate the DODP printhead to deliver ink drops (55, 57) to pixel locations upon the upper surface. The operation of the DODP printhead includes, for individual ones of the ink drops: apply a secondary waveform (54) to a piezo actuator followed by a primary waveform (56) to the piezo actuator to generate two drops (55, 57) of liquified phase change ink that merge in flight before reaching and solidifying on the upper surface.

Abstract

A 3D printing system includes a machine chassis, a vessel support, a gas pressure source (55), a build vessel, a light engine, and a lateral movement mechanism. The build vessel is supported by the vessel support and includes a transparent sheet (34). The vessel support includes a carriage (52) having a top surface. The carriage is configured to be positioned along a lateral X-axis under the transparent sheet. The carriage defines an optical path and a fluid channel (60) that at least partially surrounds the optical path. The gas pressure source is coupled to the fluid channel. Gas flowing from the gas pressure source and out of the fluid channel is configured to maintain a vertical spacing between the top surface of the carriage and the transparent sheet. The lateral movement mechanism translates and positions the carriage and light engine together along the lateral X-axis.

Abstract

A 3D printing system includes a build vessel (8), a carriage (58), and a light engine. The build vessel includes a vessel base having a downward extending tension ring that tensions a transparent sheet (34). The transparent sheet laterally bounds a build plane that is defined over orthogonal lateral axis X and Y. The carriage includes a roller (52) that extends between two opposing sides of the tension ring. The roller exerts an upward force on the transparent sheet and the two opposing sides of the tension ring. The vertical constraint of the roller biased against the tension ring provides a location and improved planarity of a supported portion of the transparent sheet adjacent to the roller. The light engine light engine is configured to selectively apply radiation to a projected area of the build plane through the supported portion of the transparent sheet.

In the context of additive manufacturing processes wherein objects are built by layered accumulations of discrete instantaneous deposits of feedstock material at specific locations according to a three-dimensional digital data model, methods are provided for improving at least one build quality attribute by adjusting a size of one or more voxel spaces for receiving discrete deposits. According to various embodiments, the quality attribute pertains to reducing excess material used in the build process or to thermal behavior of deposited materials. According to various embodiments, the size of a voxel space may be adjusting by scaling and by subdividing into a cluster of smaller spaces that warrant smaller deposits.

Abstract

In the context of additive manufacturing processes wherein objects are built by layered accumulations of discrete instantaneous deposits of feedstock material at specific locations according to a three-dimensional digital data model, methods and systems are provided for selecting an advantageous alignment between an array of fillable voxel spaces and a model layer slice. In accordance with some embodiments, variable alignment achieves an overall reduction in the amount of excess material formed by discrete depositions of material and extending beyond the contours of the object.

Abstract

Systems and processes for additive manufacturing are set forth for constructing an object by making successive discrete deposits of unitary masses of a feedstock materials at specific locations as determined by a digital data model for the object. In accordance with some embodiments, the deposits are non-continuous and performed in a sequence such that consecutively ordered deposit actions occur at deposit locations that are not physically adjacent, enabling control of thermal behaviors as a build progresses. In accordance with some embodiments, the sequencing of discrete depositing actions may be agilely rearranged to change temperatures and temperature gradients exhibited by deposited materials.

Some embodiments of the disclosure disclose manifolds, microfluidic systems and methods that provide control over fluid flow distribution to an array of bio- scaffolds contained within the manifolds. In some embodiments, multiple perfusates may be injected into the manifold via multiple inlets where the manifold contains a bio-assembly with a substrate having a bio-scaffold disposed thereon. Biological investigations of the perfusates may then be conducted in the vascular components and chambers of the bio-scaffold.

Abstract

A three-dimensional (3D) printing system includes a vessel, a coating subsystem, a calibration block, and a controller. The vessel is configured to contain a photocurable resin having a resin upper surface. The coating subsystem includes a coater module including a coater blade, a lateral movement mechanism coupled to the coater module, a sensor mounted to the coater module, and a vertical actuator system. The calibration block has a calibration surface. The controller is configured to operate the lateral movement mechanism to position the coater blade over the calibration block, operate the vertical actuator system to lower the coater blade into engagement with the calibration surface of the calibration block, operate the sensor to measure a distance to the calibration block, and store the distance as indicative of a vertical position of a lower edge of the coater blade.

The resin vessel is configured to contain photocurable resin (8). The fabrication subsystem is configured to form a 3D article (4) with layer-by-layer selective curing of the photocurable resin. The fabrication subsystem includes a build plate (10), a build plate support structure (14), and a vertical movement mechanism (16). The waste collection subsystem is attached to the build plate support structure and configured to capture partially polymerized resin as the build plate support structure moves in an upward direction. The controller is configured to (a) operate the vertical movement mechanism to translate the build plate support structure to a lower position and (b) operate the vertical movement mechanism to raise the waste collection subsystem up through the resin and to a position at which partially polymerized resin can be unloaded from the waste collection subsystem.
