EOS M290 Auburn University: additive manufacturing system for metals, SLM, DMLS

The EOS M290 is an additive manufacturing system for the production of metallic parts. The system has the following specifications: building volume of 250 x 250 x 325 mm; 400 Watt laser; EOSTATE monitoring capabilities; EOS-licensed process parameters for: Ti-6Al-4V, Inconel 718, AlSi10Mg, stainless steel 316L, stainless steel 17-4 PH and more.

RENISHAW AM250 Additive Manufacturing machine

The Renishaw AM250 features an external powder hopper with valve interlocks to allow additional material to be added whilst the process is running. The powder overflow containers are outside the chamber and have isolation valves so that unused materials can be sieved and reintroduced to the process via the hopper while the system is running. The system has a build volume of 250 mm × 250 mm × 300 mm.

Fatigue testing machines at Auburn University FAME Lab - including MTS Landmark systems, uniaxial and multiaxial testing

The FAME Lab is home to 2 MTS Landmark uniaxial fatigue machines, each with a 370.10 model load frame (100 kN capacity). These machines are ran off an MTS Series 505 SilentFlo™ Hydraulic Power Unit.  One of the fatigue machines is equipped with a furnace (up to 1000 °C) and high temperature MTS extensometer (gage length = 12 mm, axial strain = +20% / -10%). 

Fatigue testing machines at Auburn University FAME Lab - including MTS Landmark systems, uniaxial and multiaxial testing

The FAME Lab consists of an MTS 809 fatigue machine equipped with an axial-torsional (multiaxial) load frame (100 kN axial force, 1100 N-m torque capacity).  Tests are conducted using an Epsilon axial-torsion extensometer (gage length = 12 mm, axial strain = +/- 20%, torsion strain = +/- 7%)

Process thermal simulation at Auburn University FAME Lab for predicting temperatures during additive manufacturing

The FAME Lab has developed its own laser-powder bed fusion (L-PBF) additive manufacturing simulation software. This software is capable of predicting melt pool shape, heat affected zone temperature gradients, residual stresses and more. Auburn is home to the fastest supercomputer in Alabama which is currently 'Hopper' and consists of 4000 Cores & 172 Teraflops.

Freeman FT4 powder rheometer for characterizing the flow properties of powder used for additive manufacturing ASTM D7891

The FT4 is used to measure the rheology, or flow properties, of metallic powders used for additive manufacturing. In addition to the patented dynamic methodology, where a powder’s resistance to flow is measured whilst the powder is in motion, the FT4 also includes a shear cell for measuring the powder’s shear strength, a wall friction kit to quantify how a powder shears with respect to the surfaces of process equipment (in accordance with ASTM Standard D7891), as well as accessories for measuring bulk properties, such as density, compressibility and permeability.
