To expand the spectrum of known physico-chemical properties and employ the 3D-printed objects in areas such as biomedical, mechanical, electronical and so on, the introduction of fibers or particles in a polymer matrix has been widely studied and applied. In this review, all those studies that proposed modified polymer presenting advantages associated with rapid prototyping are reported.
Nowadays, all production, from the smallest ones to large companies, and research activities are affected by the use of 3D printing technology. The major limitation, in order to cover as many fields of application as possible, is represented by the set of 3D printable materials and their limited spectrum of physico-chemical properties
The modification of the most commonly used inks for 3D printers has opened the doors for a rush of new developments and possibilities, inspiring new research into the rapid prototyping of complex objects with improved material properties. All these studies significantly contributed to the field of materials science but most of the time they could only be tested on desktop printers because the commercial 3D ones are designed for printing specific resins and are not compatible with modified inks. Thus, to really affect additive manufacturing, the proposed solution should be tested by the major 3D companies (some of them have done it, others are doing it) in order to verify the impact of the composites in problems such as agglomerate formation, the blocking of printer heads, non-adhesion, and their alteration of curing times.
