Abstract: Various embodiments related to three dimensional printers, and reinforced filaments, and their methods of use are described. In one embodiment, a void free reinforced filament is fed into an conduit nozzle. The reinforced filament includes a core, which may be continuous or semi-continuous, and a matrix material surrounding the core. The reinforced filament is heated to a temperature greater than a melting temperature of the matrix material and less than a melting temperature of the core prior to drag the filament from the conduit nozzle.

Abstract: Methods for additive manufacturing using a three-dimensional printer including at least one linear feed mechanism and a print head positioned proximate a build platen are disclosed. The methods include a step of providing and/or feeding an unmelted fiber reinforced composite filament at a feed rate by the at least one linear feed mechanism. The methods include heating the filament to a temperature at which a matrix material therein flows within at least one rounded outlet of the print head. The methods include moving the print head and the build platen relative to one another at a printing rate. The methods include applying a spreading force to the filament between the at least one rounded outlet of the print head and the build platen. The methods include a step of controlling a differential in the feed rate and printing rate using the at least one linear feed mechanism so that the feed rate and the printing rate are substantially the same.

Abstract: Systems, apparatus and methods of additively manufacturing objects are disclosed. Specifically, provided herein are methods of heating objects having a particle-based support at least partially surrounding the object during portions of stages of the heating. Additionally, systems, apparatus, and methods for removing the particle-based support during heating, such that the object can continue heating to form a final part. Systems, apparatus, and methods for distributing the particle-based support to shore the objects through heating are disclosed. Systems, apparatus, and methods for removing the particle-based support are also disclosed herein.

Abstract: According to one aspect, embodiments herein provide a method for in-process inspection of a 3D printed part with a 3D printer, comprising slicing a three dimensional model to define a plurality of shell volumes, for substantially each shell volume, generating a toolpath for depositing a printing material shell corresponding to the shell volume, transmitting, together with an identification, the toolpaths defining the printing material shells for deposition by a 3D printer, receiving, together with the identification, from the 3D printer a scanned surface profile of a printing material shell, and computing a process inspection including, according to the identification, a comparison between a received scanned surface profile and a toolpath defining a printing material shell.

Abstract: In in-process inspection or calibration of a print bed or 3D printed part with a 3D printer, toolpaths defining printing material shells for deposition by a 3D printer are compared to surface profile scans from a range scanner to identify differences between the print bed, instructed deposition and the measured result, permitting pausing or alteration of the toolpaths or printing process.
