3D printing has been around for decades. But only recently has its possibilities as a commercial and consumer technology become apparent. While there are many methods of 3D printing, extrusion printing is one of the most popular.The focus of extrusion 3D printers is molding the filament into your desired object. But what is this filament, how can you choose the best one?
How 3D Printer Filaments Work
First, let’s consider what you can build with a 3D printer. For home use, 3D printers generally are used to create toys and doodads, art and clothes, footwear and jewelry. Commercially, 3D printers are used in a surprising number of applications. This can include building prototypes of parts, 3D models, and even medical bio-printing.
In fact, scientists say that a house built entirely by 3D printer may not be all that far in our future.
Obviously, these different techniques require different types of 3D printing technologies. Printer filaments are most commonly used in extrusion printing. To really understand what printer filament is, you must understand how extrusion printing works.
Basically, the idea behind extrusion printing is similar to squirting cheese out of a Cheez Whiz can, whipped cream out of an aerosol dispenser, or soft serve ice cream out of a soft serve ice cream machine.
