The process also lends itself to rasterization of layers at target resolutions, a fast process that can accommodate intersecting solids and other data artifacts. Powder bed and inkjet 3D printers typically range in price from $50,000 to $2,000,000 [citation needed]. However, there is a hobbyist DIY kit selling from $800 to convert a consumer ...
Volkswagen uses 3D printers on their assembly lines to print tooling, jigs and fixtures. They estimate that 3D printers save 250,000 EURO per year in costs. [73] One report estimates that almost 75% of desktop 3D printers made are used in industry and not by consumers. [74] Military and defense are also incorporating the use of 3D printers.
HSS is a powder-based 3D printing process that produces functional plastic parts from materials such as polyamide 12 (PA12) or thermoplastic polyurethane (TPU). The technology employs an ink jetting process that starts by spreading a thin layer of polymer powder onto a build platform.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
The process starts by slicing the 3D CAD file data into layers, usually from 20 to 100 micrometers thick, creating a 2D cross-section of each layer; this file format is the industry standard .stl file used on most layer-based 3D printing or stereolithography technologies. This file is then loaded into a file preparation software package that ...
3D Systems manufactures stereolithography (SLA), fused deposition modeling (FDM), selective laser sintering (SLS), color-jet printing (CJP), multi-jet printing (MJP), and direct metal printing (DMP, a version of SLS that uses metal powder) systems. Each technology uses digital 3D data to create parts through an additive layer-by-layer process.
Parts are manufactured by melting metal powder, layer by layer, with an electron beam in a high vacuum. This powder bed method produces fully dense metal parts directly from metal powder with characteristics of the target material. The EBM machine reads data from a 3D CAD model and lays down successive layers of powdered material.
Typically desktop 3D printers can make small plastic 3D objects. They use a roll of thin plastic filament, melting the plastic and then depositing it precisely to cool and harden. They normally build 3D objects from bottom to top in a series of many very thin plastic horizontal layers. This process often happens over the course of several hours.
