basics of additive manufacturing


More recently some visionary architects are looking to 3D printing as a direct construction method. However, as the systems have evolved and improved to incorporate dual extrusion heads, it has become less of an issue. Titanium is one of the strongest possible metal materials and has been used for 3D printing industrial applications for some time. The most common method for producing a digital model is by using computer-aided design (CAD). The laser is traced across a powder bed of tightly compacted powdered material, according to the 3D data fed to the machine, in the X-Y axes. This Job Guarantee PG Program trains you on various sub-domains of Automobile Design, such as Plastic Trims, BIW Sheet Metal, Wiring Harness and Lighting. As is the case with other powder bed systems, once a layer is completed, the powder bed drops incrementally and a roller or blade smoothes the powder over the surface of the bed, prior to the next pass of the jet heads, with the binder for the subsequent layer to be formed and fused with the previous layer.

Again, post-processing using Acetone can resolve these issues. 3D printing was initially utilized only to manufacture specific components of the engine or the automobile body, but recently, engineers developed a car, Strati, that was entirely 3D-printed.

Jetting of fine droplets is another 3D printing process, reminiscent of 2D inkjet printing, but with superior materials to ink and a binder to fix the layers. After successive layers, the object is completely printed and is supported by the surrounding powder. This process has inherent drawback of wastage of material as bulk of the raw material is cut away. Like the medical sector, the aerospace sector was an early adopter of 3D printing technologies in their earliest forms for product development and prototyping. However, these systems were all still very much for industrial applications. One of the strongest and therefore most commonly used metals for 3D printing is Stainless Steel in powder form for the sintering/melting/EBM processes. Furthermore, porosity has been an historical issue with this process, and while there have been significant improvements towards fully dense parts, some applications still necessitate infiltration with another material to improve mechanical characteristics.
