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]
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] Filament consists of one continuous slender plastic thread spooled into a reel. [4]

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 ]
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]
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 .
Foul Play is a 1978 American romantic neo-noir comedy thriller film written and directed by Colin Higgins, and starring Goldie Hawn, Chevy Chase, Dudley Moore, Burgess Meredith, Eugene Roche, Rachel Roberts, Brian Dennehy and Billy Barty. [3]
