SLM250HL and SLM500HL Machines

The generative Selective Laser Melting System 250 HL (250x250x250mm) and 500HL (500x280x325mm) produce homogeneous metal components using fine metal powders within a material density up to 99.9 %. The component quality and economical figures together with the geometrical results are focused on manufacturing environment.
The SLM 250 HL and 500 HL is of modular design and divided into various sectors that can be individually serviced, replaced or extended. The heated building platform (up to 200°C) can be moved up to 350mm in 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. Stainless Steel, Tool Steel, Cobalt-Chromium, Super Alloys, Copper alloys, Aluminum and Titanium have been processed successfully already. Further available options do increase the versatility and multiple usability of the system.

Objet Eden350V and Connex 3 Polyjet Machines

The Polyjet technology offers power and productivity along with 17 different materials to support a wide variety of rapid prototyping needs. With ultrafine 16 micron layers, the Polyjet technology rapidly prints models with smooth surfaces, thin walls, and complex shapes. Office-friendly, the Objet Eden350V has a convenient 350 × 350 × 200 mm (13.8 × 13.8 × 7.8 in) tray size and the connex3 has a convenient 500 x 400 x 200mm in tray size. Both offer a quiet, clean process based on PolyJet 3D Printing technology. The connex 3 in particular is able to print large, multi-material as well as multi-colour in a single build. Engineering plastic or rubber parts can be produced with high accuracy, repeatability and consistency.

 

   

Stratasys Dimension Elite FDM Machine

FDM works on an "additive" principle by laying down 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 .178 mm (0.007 in.), this 3D printer lets you speed up printing with a layer thicknesses of 0.254 mm (0.010 in.).

 

   

Z-Corp ZPrinter310 3DP

The proprietary ZPrint Software first converts a three-dimensional design built using 3D CAD into cross-sections or slices that can be between 0.003" – 009" (0.0762 - 0.2286 mm) thick. The ZPrinter 310 then prints these cross-sections one after another from the bottom of the design to the top.
Inside the printer there are two pistons. The feed piston is represented in the diagrams below on the left and is shown in the ‘down’ position filled with powder. The build piston is the piston on the right, shown below in the ‘up’ position. Also represented in the diagrams is the roller (drawn as a circle) and the print assembly (drawn as a square.) On the printer, the roller and the print assembly are mounted together on the gantry which moves horizontally across the build area.
To begin the 3D printing process, the ZPrinter 310 first spreads a layer of zp® series powder in the same thickness as the cross section to be printed. The HP print head then applies a binder solution to the powder, causing the powder particles to bind to one another and to the printed cross-section one level below. The feed piston comes up and the build piston drops one layer of the thickness. The printer then spreads a new layer of powder and repeats the process, and in a short time the entire part is printed.

 
   

Binhu SLS1400 and EOS P396 Machines

Two SLS equipments are available at NAMC with build sizes of 1400x700x500mm and 340x340x600mm. Both SLS machines are highly productive and allow tool-free manufacture of serial components, spare parts and functional prototypes directly from CAD data. Quality of parts is consistent and reproducible. Materials that can be processed by the SLS machines are sand (for casting applications), polystyrene (PS), polypropylene (PP) and nylon-12 (PA-12)

 
   

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 Φ350X380 mm3. Currently, Titanium Grade 2, Titanium Ti6Al4V ELI and Cobalt-Chrome (ASTM F75) powders are available for EBM A2XX. Most of powders can be recycled (up to 98%) via a powder recovery system supplied by Arcam.

 
   

RegenHU Bioprinter Biofactory Machine

The bioprinter is able to print cells and other growth factors directly. The bioprinter at NAMC features a 7 print heads and a printing volume up to 60/60/50 mm. It is equipped with a flow hood for sterile processing. The capabilities of the 3D bioprinter include multi-materials bioprinting (up to seven materials including cells), extrusion-based bioprinting, valve-based contactless bioprinting, injet bioprinting, temperature control of print heads and UV/laser curing of photo-sensitive polymers. This high end, versatile and cell friendly three dimensional bio-manufacturing instrument allows researchers to pattern cells, biomolecules and a range of soft and rigid materials in desirable 3D composite structures, mimicking biomimetic tissue models.

 

   

Choc Edge’s “Choc Creator” Chocolate printer

The Choc Creator is a simple and versatile desktop 3d chocolate printer, capable of printing tasty chocolate creations by depositing chocolate using a 10ml syringe. The Choc Creator uses premium Belgium chocolate from Callebaut that is carefully tempered before printing. The built area is 175(X)mm x 175(Y)mm wide, allowing for large chocolate creations to be printed. The line resolution of the printer is about 2 mm wide and can be controlled using a variety of syringe nozzle diameter ranging from 0.5 to 1.5 mm.
Our Choc Creator has been modified to work with open source software like Slic3r and Pronterface, allowing for a greater ease of usage and future modifications. The chocolate printer thus provides a platform allowing researchers and students to explore the possibility of food printing.

Stereolithography Machine CMET EQ-1

EQ-1 is a high performance stereolithography machine. It mounts Ultra Violet solid laser excited by Laser Diode (LD) to cure photo-curable liquid resin at a layer thickness of 50 microns. A newly developed high-speed, high-resolution scan system TSS4 is loaded to achieve faster designing speed and path accuracy. EQ-1 offers a large build size of 610x610x500mm with an exchangeable resin tank of 272 liters. The machine is equipped with a new balloon liquid surface control system, allowing the inner tank volume to be adjustable; hence expensive resin can be used effectively as compared to the conventional method.
