This paper presents the development of biocompatible polymer nano-composite material for Additive Manufacturing (AM) technology, particularly for Fused Deposition Modelling (FDM) process. The material was prepared by mechanical blending using single screw extruder nanomixer of Polycaprolactone (PCL), Montmorillonite (MMT) and Hydroxyapatite (HA). The amount of MMT material was varied from 2 - 4 (wt %) and the HA was fixed at 10 (wt %). Then, the blended material was crushed and fed into single screw extruder to produce a filament of 1.8 mm diameter. The material was characterized on mechanical properties, biocompatibility and manufacturability on fused deposition modeling machine. The results show an improvement in tensile and flexural properties by increasing the MMT. The SEM image shows the bulk formation of apatite layers on the composite surface which confirmed the bioactivity on the material. The material also was successfully tested on the fused deposition modeling machine, where rapid production of customize implant component can be produced
