RENISHAW AM250 Metal Additive Manufacturing System

renishaw-am250-02

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.

Coherent CREATOR

EOS m290-03

The Coherent CREATOR is an excellent small volume LB-PBF machine which is unique in its design with a circular coater that can decrease the build time by 30%. One of the best qualities of this system is the intuitive software package provided with the machine. It is comparatively cheaper and can rapidly print parts compared to the other 3D metal printers. This machine contains a small building platform which is much easier to change material systems compared to all of our other platforms. Also, it takes less time to prepare the build files, execute builds, and conduct maintenance.

OPTOMEC LENS 3D Additive Machine Tool

lens-optomec-01

The OPTOMEC LENS 3D Additive Machine Tool provides high-quality metal 3D printing with 10 times faster printing speed than Powder Bed Fusion systems. LENS uses directed energy deposition (DED) technology, where a high-powered laser beam is used to fabricate structures layer by layer from powdered metals, alloys, ceramics, or composites to produce fully-dense parts. Some of the advantages of DED are reduced manufacturing costs and materials, reduced process time, and the ability to process non-reactive and reactive metals. (Source: https://www.optomec.com)

Zeiss Crossbeam 550 Scanning Electron Microscope

sem

The Zeiss Crossbeam 550 Scanning Electron Microscope combines imaging and analytical performance of a high-resolution field emission SEM with the processing ability of next-gen focused ion beam (FIB). This state-of-the-art FIB-SEM has Gemini II electron optics which ensures high beam quality for high resolution (0.6 nm) imaging. Its 5 different electron detectors (including conventional and in-lens secondary electron detectors, in-lens energy selective backscattered (ESB) electron detector, a four-quadrant backscattered electron (BSD) detector, and STEM detector) enables truly versatile materials characterization. The microscope also has Oxford instruments onboard the FIB-SEM enables advanced energy-dispersive x-ray spectroscopy (EDS) and electron backscatter diffraction (EBSD) analyses. This FIB-SEM, with its Ion-sculptor Ga+ FIB at an exceptional FIB resolution of less than 3 nm, also offers superb TEM sample preparation quality. In addition, its ultralow FIB voltage and currently minimizes the amorphization zone of TEM lamella during the final thinning step.

FT4 Powder Rheometer

powder
The FT4 is used to characterize the rheology of the powder (i.e., powder flow properties). This instrument is considered as a universal powder flow tester. The FT4 is designed to simulate powder processing conditions (i.e., consolidated, moderately stressed, and aerated or fluidized states) and obtain dynamic flow (i.e., bulk and shear properties). This instrument has an unparalleled sensitivity which enables differentiation of different powder batches. Sample sizes can vary from 10 to 160 ml. In the FT4, the resistance of the powder to flow is measured while powder is in motion. The FT4 can be used for different categories of methodologies defined as Bulk, Dynamic Flow, Shear (according to ASTM D7891), and process. It can be used in many applications including pharmaceuticals, fine chemicals, food, cosmetics, toners, metals, ceramics, plastics, powder coating, cement, and additive manufacturing applications.

Anton Paar's NHT2

nano

The Anton Paar's NHT2 is a Nano-indentation Hardness Tester which provides a wide range of forces from nano- to macro-indentation for measuring some surface properties of materials such as hardness. The instrumented nano-indentation hardness tester (NHT2) is capable of covering nano, micro, and macro-indentation testing methodology. The NHT2 tester allows for studies on various materials, such as metals, ceramics, semiconductors, and polymers. The NHT2 enables one to determine a material's mechanical properties, including its hardness, elastic modulus, and fracture toughness depending on the indenter geometry. During an indentation test, the force and depth are continuously monitored and a curve of force vs. depth on the instruments is being displayed. Further, the NHT2 not only measures a sample's hardness but also it is capable of determining its elastic modulus based on the high-precision technique of Instrumented Indentation Testing (IIT).
