Drawing on its close ties with industry and world-leading capabilities in materials development, characterization, and processing, ORNL is creating an unmatched environment for breakthroughs in both metal and polymer additive manufacturing, or 3D printing.
Electron Beam Melting
Manufactures parts by melting metal powder in successive layers that are bound together utilizing a computer controlled electron beam.
Laser Blown Powder Disposition
Uses inert gas to spray powder into a melt pool created by a high- power laser beam.
Equipment: DM3D, POM
Uses a high power laser to fuse powdered material by scanning cross-sections on the surface of a powder bed.
Utilizes a liquid binding agent that is selectively deposited to join powder particles through strategic layering.
Metal Laser Melting
Powder materials are locally fused by a high-energy fiber laser that is directed by a mirror-deflecting unit to create layer-by-layer components.
Equipment: Concept Laser
Fused Deposition Modeling
Uses a heated nozzle to melt and deposit a thin lament of thermoplastic material into a two-dimensional pattern.
Equipment: Stratasys, 3D Systems, Afinia, Solidoodle
Inkjet print heads are used to jet liquid photopolymers onto a build platform. The material is immediately cured by UV lamps and solidified which allows to build layers on top of each other.
Large-scale Polymer Deposition
Polymer pellets are heated to near molten temperatures and extruded layer-by-layer onto an out-of-the-oven build platform.
