Abstract
Fused Deposition Modeling (FDM) is an additive manufacturing process by which a 3D object is created from plastic filament.Single extruder is commonly used nowadays,but there are several researcher in company had make a inovation to this technology which are the two extruder can print with two material and colors. This concept of this development are developed by several manufacturers such as Flashforge ,Leapfrog, Marketbot, Duplicator and other machines that have been developed by using multiple extrusion and two type materials. The study is focusing on the cabality of singning and joining two different material that often used in the RP especially foor FDM method which are PLA and ABS material. Each of the materials have the different temperature for bed and print. Hence, the main strength of this project is to identify, evaluate and do analysis on the joining of different materials in one sample or product by using the dual extrusion of machine. Two type of joining are used in this study which are Butt joint and Lap joint. The paramater used are Infill,air gap and raster angle is fixed to 10%,spare and 45/-45. Sample for tetsing will follow the ASTM638 Tensile test and Iso 718 for flexural test. Flexural test,ABS and PLA is the most flexural compared to others,whice are maximum value Force is 65N and for strok is 7.5mm,and for the tensile test ABS and ABS with butt joint are the most high value which are maximum value for Stress 27MPA and for the strain is 5%. The result show that combination of PLA with ABS are not so similar with the combination of ABS and ABS. The result is based on the data by using UTM machine.
