3D printing technology uses a variety of materials to build several objects. It is also called rapid prototyping technology. It uses a 3D digital model to prepare the object through layer by the layer printing method. At present lots of polymeric materials are being used with a large number of applications in 3D-printed objects. But 3D printed objects made of pure polymer show inferior thermal, mechanical, electrical and other properties, therefore having limited applicability. The addition of filler material in a pure polymer matrix enhances the functionalities of these polymers. A review of 3D printable polymers and their composites is done in this review paper
