Provided are improved steam-drying systems, the systems being configured so as to multiple resin streams into steam streams.

Drying systems

A process for making an article by additive manufacture having resistance to dripping when burned comprising (1) depositing a multitude of thermoplastic monofilament strands using a fused deposition modeling apparatus in a pattern and (2) fusing the multitude of strands together to make an article of manufacture having voids therein; wherein the article of additive manufacture has (a) at least 50% of the monofilament strands oriented within 45 degrees of the long part of the axis; (b) the multitude of strands is greater than 10; (c) having a specific micro structure; and (d) is made from a thermoplastic polymer composition that is either the combination of a thermoplastic polymer with a flame retardant compound, a thermoplastic resin having flame resistant properties, or a combination of a thermoplastic resin having flame resistant properties with a flame retardant compound.

A process for drying resinous materials, comprising: delivering, by way of a plurality of resin channels, resin fluid comprising polymer and solvent into at least first and second steam channels () having within a flow of steam, the first and second steam channels () each receiving resin fluid from a plurality of resin channels, the first and second steam channels each () being received by a stage 1 manifold (), the steam and resin being delivered under conditions so as to separate at least some of the solvent from the resin fluid; and collecting at least some of the polymer from the resin fluid.

Drying methods

Systems, devices, and methods according to the present disclosure are configured for use in additive manufacturing. Systems for additive manufacturing can include stand-alone manufacturing units, a series of units on an assembly line, or a high-capacity system with workflow automation features including a conveyor for transporting parts to or from a build area, or a robotic arm for transporting parts or adjusting a system component. An additive manufacturing system () can include a flow regulator () to change a temperature of a thermoplastic material at or in a tip () of a material extrusion nozzle cartridge (), such as to enable or inhibit flow of the thermoplastic material from the tip. The flow regulator can be configured to provide a specified gas or liquid at a specified temperature, velocity, or volume.

Rapid nozzle cooling for additive manufacturing

A reduced density article of manufacture, and process for making same, made from a thermoplastic polycarbonate composition. The reduced density article of manufacture has (1) a certain density and (2) a certain micro structure containing from 1% to 20% by volume of voids wherein at least 80% of the voids are high aspect voids and less than 20% of the voids are spherical voids with a diameter of 10 to 100 microns. The polycarbonate thermoplastic composition comprises at least 50 mole % of a certain bisphenol A. The reduced density article of manufacture is made by a monofilament additive manufacturing technique.
