Selective Laser Sintering

Posts Tagged ‘Sintering’

Selective laser sintering (SLS) is an additive manufacturing technique that uses a high power laser to fuse small particles of plastic, metal or glass powders into a mass that has a desired 3-dimensional shape. The use of Carbon Fiber increase the mechanical properties of the resultant part. In this video we show how rigid can be a part made by carbon-fiber reinforced polymer developed in Fundació CIM-UPC. Special thanks to Roger Uceda, Abeloncho Funk drummer!

We have a quick look at 3D printing, which we’ll be using to make our Low Orbit Helium Assisted Navigator’s Vulture 2 spaceplane. Thanks to Southampton University and 3T RDP Ltd for their hospitality. There’s more on our LOHAN project here: reg.cx

Open Source 3d Printer Selective Laser Sintering Design This is the design for a /really/ inexpensive dual z-axis table mechanism for an open source selective laser sintering 3D printer that PETER ( www.thingiverse.com ) has been designing. This is a follow up to the selective laser sintering powder test rig that HE recently posted ( thingiverse.com ). Instructions builders.reprap.org (the left side is designed to be cut with 4.5mm material, while the right side can be cut with 3mm material, though you may choose 4.5mm for some things, such as the gears).

Here is an old video that describes the Selective Laser Sintering (SLS) rapid prototyping process.

DMLS Direct Metal Laser Sintering process in action utilizing EOS GmbH platform, the M270. This technology sinters layers of fine metal alloys utilizing a 100 watt laser to additively manufacture real, fully dense metal parts. This geometry is building in our DirectAlloy 718 material at 20 micron layers. Notice the intelligent patterns that the laser sinters in. We have been running this equipment for 5 years and still get caught with our noses to the glass, drooling, just watching the build process… Our sincerest apologies for not including the prototypical male narrative to describe the build porcess.

Paramount was awarded a Phase II Small Business Innovation Research contract by the US Air Force Research Laboratory. This will advance the R&D of high-temperature, electrostatic-discharge (EDS) compliant laser sintering materials that have heat deflection temperatures in excess of 320 degrees C and are chemical resistant, non-outgassing, electrically and thermally conductive. In response to the Aerospace industry’s demand for ESD compliant high-temperature selective laser sintering materials, Paramount continues to develop laser selective materials for engineered aerospace and medical applications.
