摘要： A heated extruder for 3D printing of a cementitious material can include a mixing and deposition nozzle including a hopper in communication with a mixing tube, where the mixing tube can be in communication with a deposition tip. A heating element can be disposed on an outside surface of the mixing tube and configured to transfer heat to an interior portion of the mixing tube. An auger including a flight having a perforation can be disposed within the mixing tube. The auger can be configured to promote mixing and pumping of the cementitious material through the mixing tube to provide a homogeneous distribution of heat throughout the cementitious material when the heating element transfers heat to the interior portion of the mixing tube.

摘要： Systems and methods for manufacturing a product include a mixing station for preparing a solution containing a base material and a performance modifier. The base material is configured to deliver performance characteristics of the product that are preselected and the performance modifier is configured to enhance the performance characteristics. An encapsulation station produces particles of the performance modifier in a coating of the base material as an encapsulate powder. An additive manufacturing cell includes an energy source and is used to build the product from the encapsulate powder by an application of energy from the energy source.

摘要： A device for cutting a filament of a 3D printer includes a blade having a first end and a second end opposite the first end. The device also includes a support that is attachable to a heater block of the 3D printer and supports the blade, such that the blade is movable relative to the heater block. The first end of the blade is a cutting end, and the second end of the blade is a drive end. The drive end of the blade has a surface configured to receive a force from outside of the device, such that the blade moves relative to the heater block.

摘要： A semi-crystalline blended polymer useful for additive manufacturing is comprised of an amorphous thermoplastic polymer and a thermoplastic semi-crystalline polymer, each of the polymers being essentially miscible in the other and being blended at a weight ratio of amorphous polymer/semi-crystalline polymer of greater that 1 to about 20. The semi-crystalline blended polymer displays a DSC melt peak enthalpy of at least about 3 joules/g. The semi-crystalline polymer may be made by blending the aforementioned polymers at the weight ratio and subject to heating between the melt temperature of the semi-crystalline polymer and the glass transition temperature of the amorphous polymer. The semi-crystalline blended polymer may revert to essentially an amorphous polymer when additive manufactured by fusing layers of said polymer powders together.

摘要： A system for printing biomaterials can include a mixer having a longitudinal axis. The mixer can define a flow channel that extends along the longitudinal axis. The mixer can have at least one inlet configured to receive a first printable biomaterial and a second printable biomaterial and an outlet spaced from the inlet along the longitudinal axis. One or more mixing elements positioned within the flow channel between the inlet(s) and the outlet of the mixer. The mixing element(s) can be configured to control a spatial distribution of the first and second printable biomaterials across and along the longitudinal axis.
