摘要： A configurable printing bed for a 3D printer includes a bed surface and linear actuators. The bed surface includes bed surface portions. Each of the bed surface portions is supported for independent movement. When each of the bed surface portions is positioned at the reference level, the bed surface portions form different parts of a common plane. Each of the linear actuators is connected to at least one of the bed surface portions, respectively. The linear actuators are configured to generate the independent movement of the bed surface portions and to effect positioning of the bed surface portions. A 3D printer includes the configurable printing bed, an extruder, a feeding system, and a filament spool. A method for performing 3D printing includes providing the 3D printer and printing an object using the 3D printer.

摘要： A low pull force system for feeding a filament along a feed path from a source to a liquefier in a 3D printer includes a low compressive force loading drive for advancing filament from the source, a feed drive for advancing filament into the liquefier, and an in-line accumulator comprising a telescoping joint positioned in the feed path between the loading drive and the feed drive. When the telescoping joint is in a contracted position, the loading drive activates to feed filament into the feed path at a rate faster than a rate at which the feed drive advances filament into the liquefier, causing the telescoping joint to expand and accrue a slack of filament in the feed path. When the telescoping joint reaches an extended position, the loading drive deactivates while the feed drive continues to advance filament into the liquefier, and the slack of filament is consumed.

摘要： A filament feeder (1) for use in a fused filament fabrication printer comprises a feeder body (2) which comprises a channel (3) for guiding a filament (F) there through. A first and a second driven grip roller (4, 5) are arranged on opposing sides of the channel (3) for clamped engagement with the filament (F), wherein the first grip roller (4) is rotationally arranged about a first roller axis (4a) and the second grip roller (5) is rotationally arranged about a second roller axis (5a). The feeder comprises a first drive gear (6) for driving the first grip roller (4), the first drive gear (6) being rotatably arranged about the first roller axis (4a), a second drive gear (7) for driving the second grip roller (5), the second drive gear being rotatably arranged about the second roller axis (5a), and a suspension system (S) for suspension of the first and second grip roller (4,5) and of the first and second drive gear (6,7). The suspension system (S) is arranged to allow lateral movement of the first and second grip rollers (4, 5) with respect to the channel (3) for providing a variable distance (D+AD) between the first and second roller axes (4a, 5a).

摘要： A method of controlling drop mass in a liquid ejector is disclosed which includes advancing a printing material feed source to introduce a quantity of a printing material into a liquid ejector, counting a quantity of ticks produced by an encoder coupled to the printing material source during a time period to calculate a mass of the printing material, counting a quantity of pulses produced by the liquid ejector during the time period, and entering into a control system the quantity of ticks produced by the encoder and the quantity of pulses produced by the liquid ejector. The method may include comparing the quantity of printing material calculated by using the quantity of ticks produced by the encoder to the quantity of printing material measured by using a level sensing system. The method of controlling drop mass in a liquid ejector may include steps performed by a microprocessor.

摘要： A continuous filament additive manufacturing machine for building a part by laying down a continuous mono-filament or composite filament material layer by layer on a tool or substrate. The machine includes a system operable to move in at least three degrees of freedom, and a placement module coupled to the system and being configured to deposit the continuous filament material. The placement module includes a guide for guiding the material to the part and an ultrasonic compaction device for compacting the material as it is being deposited from the placement module. The compaction device includes an ultrasonic driver, an attachment member and a plurality of ultrasonic horns independently coupled to the attachment member and being movable independent of each other. The plurality of ultrasonic horns are ultrasonically vibrated to melt or flow the material and cause the material to fuse and be compacted to the tool or substrate.
