| 总结: | 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. |
