Specification for a Direct Metal Laser-Sintering Machine

The Technical Services in the Engineering Directorate at NASA Langley Research Center is in need of a Direct Metal Laser-Sintering Machine. The machine will be used to build research hardware. This technology gives the engineers the ability to make hardware that could not be built by conventional machining.

Requirements:

-Shall manufacture parts by selective laser melting technology, which produces homogeneous, fully dense metal components using powder base materials by an additive, layer-by-layer process.

-Shall manufacture fully dense end-use metal parts requiring no post-cure process.

-Shall build parts within a tolerance of +/-.005.

-Shall build parts with minimal wall thickness of 180 um -Shall include build parameters for manufacturing parts out of Aluminum, Stainless Steel, Cobalt Chrome, Inconel and Titanium in one machine.

-Shall have an open software architecture to enable the user to modify the system parameters to meet a variety of hardware manufacturing needs.

-Shall have a build volume at least 280 x 280 x 350 mm.

-Shall have the capability to build in variable layer thicknesses from 20-100 um.

-Shall have at least dual 400 watt Fiber lasers.

-Shall have a fully enclosed stand alone powder sieving system with ultrasonic cleaning.

-Shall have an electronic visual inspection system to detect the powder preparation, layers, and performance.

-The system shall be able to warn the user of issues over a network connection.

-Driving software shall run on a Windows 10 Operating System, import .stl files, and generate any necessary support structure.

-Shall have Ethernet Network connection.

-Shall include shipping, installation, machine set-up, and training -Shall include a 24 month warranty that covers of all parts, including the laser with no limit on hours, labor, and travel for the repairs.
