3D printing is a cost effective method to analyze your part designs before committing to the high cost of tooling development or the machining of production parts. NeoMetrix utilizes MultiJet, ColorJet, PolyJet, SLS and SLA technologies for 3D printing. Our Objet Connex can produce parts in a variety of different photopolymer materials. Ultra fine layer thickness create accurate, clean, smooth and highly detailed 3-dimensional models for a variety of applications across countless industries.
Types of Technologies:
ColorJet Printing (CJP) is an additive manufacturing technology which involves two major components – core and binder. The Core™ material is spread in thin layers over the build platform with a roller. After each layer is spread, color binder is selectively jetted from inkjet print heads, which causes the core to solidify. The build platform lowers with every subsequent layer which is spread and printed, resulting in a full-color three-dimensional model. From concept models to iterations of detail components for a design study, ColorJet offers a fast, cost-effective solution for fabricating complex geometries in vibrant color.
MultiJet Printing is an additive manufacturing technology where products are produced through an inkjet printing process. Products are built up, layer by layer, in a photo-curable plastic resin or casting wax material using print head technology, with a variety of color options available too. Parts have smooth finish and can achieve accuracies rivaling SLA for many applications. Another benefit of MultiJet printers is that they are office compatible, using standard office electricity to provide convenient and affordable access to high-quality prototypes and indirect manufacturing aids.
PolyJet 3D printing is an additive manufacturing technology that features customizable material properties and impressive surface finishes. The process involves jetting tiny layers of a liquid, UV-curable photopolymer onto a tray to build models and prototypes of the most complex geometries and detail. With PolyJet 3D printing, users can make multi-material prints, incorporate different colors, and create a model that features extremely smooth surface finishes that resemble what the final product might look like.
Stereolithography (SL) printers transform liquid raw material into solids through the use of light. Because SLA prints don’t normally need struts or supports, these printers have various advantages in terms of accuracy, efficiency and the capability to produce complex objects in a single pass. The problem with them is that the choice of materials is very limited. They are ordinarily exotic liquid polymers, and can’t be used to print metal or chocolate.
Selective Laser Sintering (SLS)
Selective Laser Sintering systems are granular printers are completely different machines because their material is not filament, but, rather, powdered metal. These printers are usually based on laser technology, but they’re not very similar to your office laser printer. They use a strong laser to selectively fuse granular materials. The strength of objects produced with SLS 3D printers is better than that of SL 3D printers. New systems take SLS technology directly to the manufacturing floor – all with a low cost and very little time consumption with no CNC programming or tooling necessary. It also has some use as a production method.
Direct Metal Laser Sintering (DMLS)
In Direct Metal Laser Sintering (DMLS) high temperature laser melts the metal powder and creates an object layer-by-layer based on a CAD file. This process is often used when working with titanium, steel or aluminum. It is an extremely effective method for producing or prototyping parts of high resilience. DMLS can be used for very small parts and features, and because it is an additive process, it can reproduce geometries that might be impossible to machine such as enclosed spaces
Fused Deposition Modeling (FDM)
FFF/FDM usually relies on thermoplastic “filament” heated by the printer extruder before being placed on the print bed. The majority of FFF printers rely on ABS and PLA plastic filament, but the most recent models also use polycarbonate (PC), high-density polyethylene (HDPE), high-impact polystyrene (HIPS) filament. Some substitute metal wire for the typically used plastic, while others use sawdust to develop quasi-wood objects.
Binder Jetting is one of the most simple, basic forms of additive manufacturing. This is perhaps the cheapest and fastest form of 3D printing. Inkjet heads deposit a liquid onto the powder (event metal powder), binding the material layer-by-layer based on data from a CAD file. The process is repeated until the complete part has been formed and after completion, the unbound powder is removed leaving the finished object. It is typically used when working with large objects/structures composed of stainless steel or bronze
