Today, additive manufacturing (AM) is the most recent technology used to produce detailed and complexly built parts for a variety of applications. The most emphasis has been given to fused deposition modeling (FDM) in the development and manufacturing fields. Natural fibers have received attention in the area of 3D printing to be employed as bio-filters with thermoplastics, which have prompted an effort for more ecologically acceptable methods of manufacturing.

Article Synopsis
  • Fused Deposition Modeling (FDM) can create complex designs using thermoplastic or composite materials, making it essential to analyze how printing parameters affect part quality and performance.
  • The study focused on optimizing FDM parameters for oil palm fiber reinforced thermoplastic composites, including layer thickness, orientation, infill density, and printing speed, to assess their impact on mechanical properties through tests and statistical analysis.
  • The results revealed that the best settings for mechanical strength were a layer thickness of 0.4 mm, a flat orientation at 0 degrees, 50% infill density, and a speed of 10 mm/s, highlighting the link between printing conditions and part performance.

Fused deposition modelling (FDM) is a filament-based rapid prototyping technology that allows new composite materials to be introduced into the FDM process as long as they can be manufactured in feedstock filament form. The purpose of this research was to analyze the rheological behavior of oil palm fiber-reinforced acrylonitrile butadiene styrene (ABS) composites when used as a feedstock material, as well as to determine the best processing conditions for FDM. The composite's shear thinning behavior was observed, and scanning electron microscopy was used to reveal its composition.

Particleboard is not entirely a wood replacement but a particular material with its properties, making it more effective at different times than heavy or solid wood. The world's biggest concern is environmental problems with formaldehyde as a particulate board binder that can lead to human carcinogenic agents. A cradle-to-gate life cycle assessment (LCA) of particleboard production was performed using openLCA software.
