“…Changing the characteristics of the powder can drastically influence the mechanical and flow properties of the feedstock materials, as has been reported in the PIM and the particulate composite literature [ 127 , 128 , 129 ]. For feedstock materials to be used in FFF this is particularly critical because changing the characteristics of the powder can lead to filaments with low mechanical properties that are not printable.…”

Additive manufacturing (AM) is the fabrication of real three-dimensional objects from metals, ceramics, or plastics by adding material, usually as layers. There are several variants of AM; among them material extrusion (ME) is one of the most versatile and widely used. In MEAM, molten or viscous materials are pushed through an orifice and are selectively deposited as strands to form stacked layers and subsequently a three-dimensional object. The commonly used materials for MEAM are thermoplastic polymers and particulate composites; however, recently innovative formulations of highly-filled polymers (HP) with metals or ceramics have also been made available. MEAM with HP is an indirect process, which uses sacrificial polymeric binders to shape metallic and ceramic components. After removing the binder, the powder particles are fused together in a conventional sintering step. In this review the different types of MEAM techniques and relevant industrial approaches for the fabrication of metallic and ceramic components are described. The composition of certain HP binder systems and powders are presented; the methods of compounding and filament making HP are explained; the stages of shaping, debinding, and sintering are discussed; and finally a comparison of the parts produced via MEAM-HP with those produced via other manufacturing techniques is presented.

“…A decrease in viscosity has also been reported in the literature when using coarser particles in PIM feedstocks [4]. Additionally, it has been reported in the literature of polymer-metal composites filled with particles that increasing the particle size decreases the modulus [5] and elongation at break [6] of the composite materials. Therefore all our results are in agreement with the literature.…”

“…Composites prepared by melt compounding has a uniform dispersion of reinforcements in the matrix material and reduced agglomeration rate [7,9]. From the results it can be observed, that melt compounding by twinscrew extrusion is the most suitable method, to develop composites with uniform distribution of reinforcement, in the matrix material.…”

In this present investigation, the influence of reinforcing tungsten (W) particles in High-Density Polyethylene (HDPE) on mechanical and thermal properties, has been studied. W reinforced HDPE composites are processed by melt compounding method, with W varied in proportion of 1%, 3%, 5% and 7% by weight. The test specimens were prepared by injection molding as per ASTM standards and analyzed by X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Mechanical and Thermal Characterization. XRD results show that, the intensity count at angle 40.3°, 58.7°, 73.6°and 87.1°increases with the increase in wt% of W particles. SEM analysis reveals that, composites containing 1wt% of W has uniform dispersion in the HDPE matrix. In mechanical characterization, tensile strength and flexural strength of the specimen reported a sharp increase with the addition of W at 1wt%, followed by a negative trend for the higher content of W particles. However, the impact strength result shows that specimen with 3wt% of W content has the highest toughness. Further from thermal characterization, Thermo Gravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) results show that degradation temperature and the melting point of composites improve with an increase in W content. Composite with 7wt% W content has the highest degradation temperature and melting point.
