Nanofiber production may become cheaper due to a new development. Researchers from Cambridge, USA-based Massachusetts Institute of Technology (MIT) have effectively utilized a less expensive commercially available 3-D printer to develop a nozzle microfluidic device to produce nanofibers. 3-D printed microfluidic device enables to get uniform nanofibers providing flexibility with regard to the structure of the webs. According to researchers, using 3-D printed device to produce nanofibers will help to avoid the need for cleanroom and will make the process cheaper. The technique uses emitters or nozzles which have holes made through them and hydraulically the fluid to be electrospun, is poured into the holes until holes are full. Then only, electric field is applied to develop nanowebs. The researchers term this procedure as "internally fed."
