POWDER BASED AM MACHINES​

1) SELECTIVE LASER MELTING (SLM)

SLM250HL, SLM280HL and SLM500HL Machines

The Selective Laser Melting systems 250HL (build volume 250 x 250 x 250) mm3, 280HL (280 × 280 × 365 mm) and 500HL (500 × 280 × 325) mm3 produce homogeneous metal components using fine metal powders, achieving material densities of up to 99.9 %.

The SLM 250HL, 280HL and 500HL feature modular designs divided into various sections that can be individually serviced, replaced or extended. The heated build platform (up to 200°C) can be moved up to 350 mm in the Z-direction. In addition to the patented new bidirectional loader movement, the SLM excels with a safe filter system and highly efficient patented protective gas consumption. The system is fitted with the software SLM® Auto-FabCAM, which has already proven itself for functional strategy and production-oriented data processing.

The SLM system can process most metals. Various Stainless Steels, Tool Steels, Cobalt-Chromium, Super Alloys, Copper alloys, Aluminium and Titanium have been processed successfully already. Further options are available that increase the versatility and multiple usability of the system. Further available options do increase the versatility.

DMG MORI LaserTec 65

DMG MORI integrates for the first time the additive manufacturing into a high-tech 5 axis milling machine. This innovative hybrid-solution combines the flexibility of the laser metal deposition process with the precision of the cutting process and therewith allows additive manufacturing in milling quality. The process uses the metal deposition by powder nozzle, which is up to 10 times faster than the generation in the powder bed.

Up to now additive technologies have been used to generate prototypes and small parts. By combining both, additive manufacturing via powder nozzle and the traditional cutting method in one machine, totally new applications and geometries are possible. Especially large workpieces with high stock removal volumes are now possible to be machined in an economical way. The flexible change between laser and milling operation allows the direct milling machining of sections which are not reachable anymore at the finished part.

 













2) ELECTRON BEAM MELTING (EBM)

Arcam EBM A2XX Machine

​The electron beam melting (EBM) can produce fully dense metal components by utilizing a high power electron beam. This translates to high melting capacity and high productivity. The process takes place in a vacuum and at elevated temperatures, resulting in stress relieved components with material properties better than cast and comparable to wrought materials.

The EBM A2XX offers a build volume of Ø350 mm × 380 mm. Currently, titanium Grade 2, titanium Ti6Al4V ELI and Cobalt-Chrome (ASTM F75) powders are available for the EBM A2XX. Most of the powders can be recycled (up to 98 %) via a powder recovery system supplied by Arcam.​

SOLID BASED AM MACHINES​

1) FUSED DEPOSITION MODELING (FDM)​  

Stratasys Dimension Elite FDM Machine

FDM works by laying down extruded material in layers. A plastic filament wire is unwound from a coil and supplies material to an extrusion nozzle which can turn the flow on and off. the nozzle is heated to melt the material and can be moved in both horizontal and vertical directions by a numerically controlled mechanism, directly controlled by a computer-aided manufacturing (CAM) software package. The model or part is produced by extruding small beads of thermoplastic material to form layers as the material hardens immediately after extrusion from the nozzle. Stepper motors or servo motors are typically employed to move the extrusion head.

The Dimension Elite 3D Printer features the finest resolution of any Stratasys Design Series Performance 3D Printer. Driven by Fused Deposition Modeling (FDM) technology, it prints in nine colors of real ABSplus thermoplastic. For times when you don’t need the finest Dimension resolution of 0.178 mm (0.007 in.), this 3D printer lets you speed up printing with a layer thicknesses of 0.254 mm (0.010 in.).
