The invention relates to manufacturing and more specifically to additive manufacturing. Fused deposition manufacturing (FDM) makes use of a nozzle to deposit beads of material in layers to form objects.
When fabricating objects with an additive manufacturing system that use a nozzle to deposit extruded material, we have found that this material often bulges above the nozzle face.
ORNL worked with Eck Industries, Inc. to compare the heat treatment response of cast aluminum alloy A206 when processed in a magnetic field with that of a conventional heat treatment.
The invention relates to additive manufacturing and more specifically to a captive build platform for holding a part. A build surface with unique geometry is provided to allow the first layer of an additively manufactured part to be captively affixed to the build platform.
The invention relates to additive manufacturing and more specifically to apparatuses and methods for producing large carbon fiber parts with high processing rates.
The invention relates to additive manufacturing and more specifically to apparatuses and methods for producing large parts with high deposition rates.
Conventional fused deposition manufacturing methods rely on thermoplastic deposition materials. The present invention involves additive manufacturing that uses reactive polymers as deposition materials. Reaction takes place following deposition.
The invention relates to additive manufacturing and more specifically to materials and methods for producing articles at room temperature.
Conventional preparation of Fused Deposition Manufacturing (FDM) fiber relies on melting and mixing of polymers in screw-type extruders. Recent tests have shown that this process is difficult when second phase reinforcement is included in the form of a fiber.
A method has been developed at ORNL that selectively dissolves both aluminum and magnesium from aluminum based alloys in a non-aqueous solvent.
