ARBURG Plastic FreeeFormer Technology (APF)

ARBURG is one of the world's top manufacturers of high-quality plastic injection molding machines and has decades of experience in manufacturing top injection molding machines.
With its electric, hybrid and hydraulic plastic injection molding machines, turnkey systems and its industrial additive manufacturing systems, ARBURG is a global leader in the industry.
In APF technology, the standard plastic particles are first melted in a plasticizing cylinder, which is the same as injection molding. However, in contrast to injection molding, molds are no longer used. Instead, nozzles using piezoelectric technology can be opened and closed up to 100 times per second, resulting in tiny plastic drops, which are then heated and extruded. Repeat printing layer by layer to build a 3D object layer by layer from the droplets.
