PLA objects can be fabricated by 3D printing, casting, injection moulding, extrusion, machining, and solvent welding. PLA filament for use in 3D printing. PLA is used as a feedstock material in desktop fused filament fabrication by 3D printers, such as RepRap printers. [39] [40] PLA can be solvent welded using dichloromethane. [41]
3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. [1] Filament comes in a range of diameters, most commonly 1.75 mm and 2.85 mm, [2] with the latter often being confused with the less common 3 mm. [3]
It is also used in the manufacture of plastic food wrap and similar products to help prevent pieces of plastic from sticking together because of static electricity. In the UK, many carrom players use a version of anti-set-off spray powder from the printing industry [ citation needed ] which has specific electrostatic properties with particles ...

Left: individual linear polymer chains Right: Polymer chains which have been cross linked to give a rigid 3D thermoset polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (). [1]
Conductive anodic filament, also called CAF, is a metallic filament that forms from an electrochemical migration process and is known to cause printed circuit board (PCB) failures. Mechanism [ edit ]
Polycondensation of glycolic acid is the simplest process available to prepare PGA, but it is not the most efficient because it yields a low molecular weight product. Briefly, the procedure is as follows: glycolic acid is heated at atmospheric pressure and a temperature of about 175 to 185 °C is maintained until water ceases to distill ...
Filament winding is a fabrication technique mainly used for manufacturing open (cylinders) or closed end structures (pressure vessels or tanks). This process involves winding filaments under tension over a rotating mandrel .
