Abstract A new concept of top‐down electrospinning is described. A dedicated apparatus was designed including the adaptation of a movable needle system in combination with a thin conveyor belt made of an insulation material on the top of the grounded collector plate. The new design, termed ‘needle printing’, permits to electrospin mats with increased size, homogeneous and controllable thicknesses. Due to the increase of bending instability and to the ‘needle printing’, the produced fibres are more regular in shape, longer and are deposited more stretched. In contrast to traditional electrospinning, the fibre population is the same in all regions of the mats imparting the same morphological and mechanical properties to each point of the produced structures.
