Indeed, a recent feature article highlights four methods to prepare NHC films [16]. For example, Crudden and co-workers have presented

• [1][2]. These attractive features have led to applications of 3DP in diverse fields including tissue engineering [2][3], microfluidics [4], robotics [5], and batteries [6][7]. 3DP involves a computer-aided design of the target structure sliced into 2D layers and printed layer-by-layer [2][3]. Four

• methods of 3DP are most common. Fused deposition modeling (FDM) involves heating a feed filament past the melting point of the material and extruding it onto a platform, which moves progressively downwards as layers are printed [8][9]. Inkjet printing deposits droplets of ink onto a platform, with ink

When comparing the four methods used for determining the particle/crystallite size, the use of Scherrer’s equation yielded most accurate results [54]. It was the only method which could provide two dimensions
