The common rule-of-thumb is that it should take roughly 2 minutes to properly brush one’s teeth, which pertains to using some elbow grease with a manual toothbrush to the convenience of electric toothbrushes. Now, the Unico, a “smartbrush mouthpiece” as its creators call it, claims that it will clean your teeth in only three seconds. Yes, THREE SECONDS; that’s 2.5% of the old rule-of-thumb’s time!! This sounds like it’s straight out of science fiction!!
Let’s go back, kinda-sorta way back, back when 3D printing was just starting to enter into the mainstream. Back then the only 3D printers available for the consumers market utilized a popular technique reffered to as the filament deposition modeling process, or FDM. FDM 3D printing involves a printer feeding a single strand of a plastic filament through a hot nozzle and layer-by-layer carefully deposits the molten plastic onto a build plate, thus creating a 3D object. Despite FDM being the most popular type of 3D printer, recently a newer technology called stereolithography, or SLA, is starting to shake-up the 3D printing market.
