Abstract

Nowadays, 3d printers is an advanced technologies that use to tangible objects that occupy space. Like a normal paper printer, 3d printer also need an ink or filler to perform printing process but what make it difference is, ink for 3d printer is in solid state and it is called filament. Polylactic acid (PLA) and Acrylonitrile Butafiene Styrene (ABS) is a common material use to create filament. Printing using filament that contain 100% PLA can only withstand small load or force which mostly use to create product that can be use as a prototype or merchandise. Other than that, PLA can be recycle but due to its low melting point, recycling PLA is not main consideration. In this research, the main focus is to create biocomposite material to use as a material to create a filament that will has stronger and higher thermal deflection properties. The idea is sugar palm fibre as natural fibre will reinforced by PLA as matrix. Creating this biocomposite material will need several process from degradation of SPF, fibre treatment, mixing, extrusion process until the analysis phase which is thermogravimetric (TGA), Differential scanning calorymetri, and rhological studies. Creating hypothesis of this research required 4 specimen to undergoes these 3 analysis which is untreated SPF,and treated SPF that divided in three treatment which is NAoH solution, silane solution, and NAoH + Silane treatment. It is believed that biocomposite material will have higher melting point, stronger bond, and higher thermal stability which make it will be usable as a daily product and better at recycling process.
