![]() ![]() The Library’s Makerbot Replicator Mini+ 3D printer uses 1.75 mm PLA filament. The two most common types of filament used by hobbyists are ABS (acrylonitrile butadiene styrene) and PLA (polylactic acid). More intricate models may take just as long, even if they don’t use as much filament.ĭifferent 3D printing methods use different types of filament. Models that are just a few inches in height can have hundreds of layers of filament and can take hours to build. Depending on the complexity of the design, it may take a few minutes or a few hours. It depends, but probably longer than you might expect. How long does it take to 3D print something? The plastic cools off almost immediately, so the finished object can be handled right away.Ī short time-lapse video of a 3D printer in action. ![]() The design is then sent to the 3D printer, where plastic filament is melted through a heated nozzle and laid down layer by layer via a robotic arm. Software is then used to digitally “slice” the designed object into hundreds of horizontal layers. You begin by creating a virtual design on a computer or by using a 3D scanner to replicate an existing object. 3D printing, also called additive manufacturing or fused filament fabrication, is a process of making a three-dimensional object from a digital file. ![]()
