PLA is soluble in a range of organic solvents. [37] Ethyl acetate is widely used because of its ease of access and low risk. It is useful in 3D printers for cleaning the extruder heads and for removing PLA supports. Other safe solvents include propylene carbonate, which is safer than ethyl acetate but is difficult to purchase commercially.
Demounting is the process of removing a print from the mounting material. This is often done because older mounts were usually made from acidic paper materials that can deteriorate the paper or fade colorants. Mounts are usually adhered to prints through adhesive agents that can cause yellow distortions on the paper. [7]
3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. There are many types of filament available with different properties.
Photolithography allows the complex wiring of an electronic system to be rapidly, economically, and accurately reproduced as if run off a printing press. The general process is applying photoresist, exposing image to ultraviolet rays, and then etching to remove the copper-clad substrate. [28] A printed circuit board-4276
December 2009) (Learn how and when to remove this message) An ABS 3D bell manufactured with a 3D printer Engineering plastics [ 1 ] are a group of plastic materials that have better mechanical or thermal properties than the more widely used commodity plastics (such as polystyrene , polyvinyl chloride , polypropylene and polyethylene ).

Contributing factors were the development of computer-aided drafting and printing, the speed of machine printing, and the introduction of larger xerographic machines or large format printers from companies like Ricoh and Xerox. The cost of blueline production materials and equipment, the fact that the prints themselves faded in sunlight, and ...
3D printing speed refers to only the build stage, a subcomponent of the entire 3D printing process. However, the entire process spans from pre-processing to post-processing stages. [ 7 ] The time required for printing a completed part from a data file (. stl or .obj ) is calculated as the sum of time for the following stages:
