Fused-filament-fabrication (FFF) printers took center-stage at this year’s Inside 3D Printing Conference & Expo, held April 10 to 12 at New York City’s Javits Center. The sheer number of companies entering this field shows the potential market size and profits that are possible (PricewaterhouseCoopers estimates $16.2 billion by 2018). Of course, as you’ll see, there was more than just FFF printers on display.
