摘要： An additive manufacturing apparatus includes a vat with multiple chambers and at least one of the chambers is a resin chamber configured to receive a radiant-energy-curable resin. A build surface is defined by the resin chamber within the vat, wherein at least a portion of the build surface is transparent. The additive manufacturing apparatus includes a stage that is positioned facing the vat and the build surface and the stage is configured to hold a stacked arrangement of one or more cured layers of the radiant-energy-curable resin.

摘要： A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head operatively connected to and moveable by the support. The print head may include a supply of continuous reinforcement, an outlet configured to discharge the continuous reinforcement, and a tensioning module disposed between the supply and outlet. The tensioning module may be configured to generate a signal indicative of a tension in the continuous reinforcement. The system may also include a processor programmed to selectively cause the supply to dispense the continuous reinforcement based on the signal.

摘要： Example implementations relate to process capability procedures for additive manufacturing machines. One example implementation receives and prints two objects with corresponding process values for a set of process parameters within two build regions of the build volume. Measurements are made of each object comprising print parameters and a dataset comprising data representing the process values associated with the print parameters and data representing the second process values associated with the second print parameters is generated.

摘要： A method for producing a component from two or more sub-components includes the steps of: producing each of the sub-components using an additive manufacturing process in which a resin, which is radiant-energy-curable, is partially cured using a selective application of radiant energy, wherein each sub-component includes a joint surface in which the resin is partially cured which is cured to a lesser degree than the remainder of the respective sub-component, so as to leave the joint surfaces in a condition suitable for bonding; assembling the sub-components with their respective joint surfaces in mutual contact; and performing a secondary cure of the partially-cured resin at the joint surfaces using an application of radiant energy, so as to further cure the partially-cured resin and bond the sub-components to each other, thereby forming the component.

摘要： Disclosed are a system for and a method of manufacturing a three-dimensional (3D) structure. The method may include injecting a fluid with a first pressure toward a surface of a first output layer to form a softening layer in the first output layer, injecting the fluid with a second pressure toward the softening layer to form an uneven structure in the softening layer, the second pressure being higher than the first pressure, and forming a second output layer on the softening layer with the uneven structure.
