“…The PLA/SS composite filament presented the highest remaining percentage weight of 61.73%, which was higher than that of PLA/Fe (45.92%) and pure PLA (2.39%). It can be discussed that the remaining percentage weight is possibly from the reinforcement particles corresponding to the previous work [1]. Thus, the higher change of glass transition temperature of PLA/SS compared to pure PLA is caused by the high percentage of filler.…”

“…Similarly, the elongation at break of PLA/Fe was higher than PLA/SS about 1.2 times. It can be noted that elongation at break of the printed specimen was more than the filament because of the difference in cross-sectional areas [1]. The printability of PLA/Fe composite was further observed at different printing temperatures of 260-290 ˚C and speeds of 30, 60, and 90 mm/s, as demonstrated in Fig.…”

“…Particle reinforcement is an important reinforcement for improving mechanical properties such as mechanical strength, strength-to-weight ratio, stiffness, and specific energy absorption of polymer matrix composites (PMCs) [1]. Fused Filament Fabrication (FFF), also known as trademark Fused Deposition Modeling (FDM), is one of the popular processes for 3D printing technology.…”

Metal particle reinforcement plays an important role in the mechanical properties and printability of composite materials for FDM 3D-printing technology. PLA/Iron composite filament is widely used in many applications, such as magnetic and biomedical devices. This research aims to study the effect of iron particles on the printability and mechanical properties of PLA/Iron composite and compare it with another PLA composite of PLA/Stainless steel composite. The PLA/Iron (Fe) and PLA/Stainless steel (SS) composites were printed at different printing temperatures between 260-290 °C, printing speeds between 30-90 mm/s, and infill density of 100%. The max stress and elongation of printed PLA/Fe composite were higher than that of printed PLA/SS composite about 1.5 and 1.2 times. Moreover, the highest max stress of printed PLA/Fe composite specimens was 40.20 MPa at a printing temperature of 280 °C and printing speed of 60 mm/s. The optical microscope observed the homogeneous iron and stainless-steel particle distribution in PLA composite matrix and revealed the printed structure.
