NovaSpider MEW

Melt electrostatic writing (melt electrowriting), is a processing technique to produce fibrous structures from polymer melts. In this particular case of electrospinning, the collection of the fiber can be very focused. Therefore, combined with moving collectors, melt electrospinning writing is a way to perform 3D printing with ultrathin fibers. Moreover, polymer melts eliminates the need for volatile solvents. 

Melt electrowriting uses translating collectors or heads to place defined microfibers in a way that opens up new possibilities for many applications. Melt Electrowriting (MEW) is solvent-free, and GMP-manufactured polymers can be used as received. As an additive manufacturing process, it allows such design principles to manufacture new, orderly microstructures.
