Additive manufacturing and product manufacturing Additive manufacturing, also known as 3D printing, is a technology that produces three-dimensional parts from its digital representation, through consecutive addition of material. It offers the possibility to produce parts without the design constrains of traditional manufacturing. Components that would not have been possible to manufacturing conventional methods and process, can be now made using a wide range of materials with additive manufacturing. Additive manufacturing is being used to produce the most demanding applications such as medical and aerospace components.We in IND Robotics and Aviation Pvt Ltd manufacture the Additive manufacturing machines.

Stereo lithographic 3D printers (known as SLAs or stereo lithography apparatus) position a perforated platform just below the surface of a vat of liquid photo curable polymer. A UV laser beam then traces the first slice of an object on the surface of this liquid, causing a very thin layer of photopolymer to harden.
The perforated platform is then lowered very slightly and another slice is traced out and hardened by the laser. Another slice is then created, and then another, until a complete object has been printed and can be removed from the vat of photopolymer, drained of excess liquid, and cured.For further details please contact info@ind-ra.com
Digital Light Processing (DLP) is a video technology created by Texas Instruments that is used for front and rear projection units. DLP technology is common for rear projection in TVs and it is also used in front projectors for units designed for businesses and classrooms. Presently, DLP comes in two major forms: 1-chip DLP and 3-chip DLP.
Digital Light Processing makes use of micro mirrors, called a Digital Micro mirror Device, to reflect light and color onto a screen. These micro mirrors are positioned in a semiconductor chip and are very small. Generally, a micro mirror pitch may measure less than 5.4μm. Each of these mirrors projects one or more pixels in the image. The number of mirrors generally correspond to the resolution of the projected image. The movement of the mirrors allows the DLP device to create colors and gray shades that can form video images. All DLP chips are produced by Texas Instruments.For further details please contact info@ind-ra.com
It is commonly used for modeling, prototyping, and production application. Objects created with an FDM printer start out as computer-aided design (CAD) files. Before an object can be printed, its CAD file must be converted to a format that a 3D printer can understand — usually .STL format.
Process fabricates the parts by extruding molten thermoplastic material through a small nozzle to form a thin bead or road that is deposited in a predetermined manner. The extrudate bondsto the previous layer and the adjacent road and solidifies quickly as a result of heat conductionFor further details please contact info@ind-ra.com
Selective Laser Sintering (SLS) is an additive manufacturing process. A high powered laser is used in this additive manufacturing technique in SLS. Our technology allows the laser to fuse tiny metal, plastic, glass or ceramic particles into a 3D Model. SLS machines also use CAD files to help produce the prototype, and selectively fusing powdered materials. This fusing is achieved by scanning cross-sections, which are also generated from CAD data. After each section has been scanned, the base of the machine is lowered, in order to apply the next layer. This additive manufacturing technique also permits a wide use of materials. A great selection of polymers (such as polystyrene, nylon, titanium, alloys and steel mixtures) are available for your unique rapid 3D prototype. For further details please contact info@ind-ra.com
Selective laser melting uses a laser to melt successive layers of metallic powder. The laser will heat particles in specified places on a bed of metallic powder until completely melted. The CAD 3D file dictates where melting will occur.
Then, the machine will successively add another bed of powder above the melted layer, until the object is completely finished.
The most common applications for this technology are in the aerospace industry, as complex parts can be made with additive manufacturing, which overcomes the limitations of conventional manufacturing. It can also result in the reduction of parts needed.For further details please contact info@ind-ra.com
Electron beam melting (EBM) is an innovative additive manufacturing (AM) process in which metal powder or filament is completely melted by a concentrated beam of electrons. Production in a vacuum chamber ensures that oxidation will not compromise highly reactive materials like titanium. Vacuum production is also required so electrons don’t collide with gas molecules.
Not long ago, most EBM projects merely illustrated the considerable possibilities of the AM process. Today, the potential of electron beam melting technology is more fully realized as it is used to print components used in demanding aerospace, automotive, defense, petrochemical and medical applications.For further details please contact info@ind-ra.com
