“…Te report suggests that adding 14% Bz as reinforcement in PLA matrix will yield a proper dispersion composite flament for the 3D printed application. Here, the agglomeration is a difcult task with increased reinforcement [26]. Bz with less than 18% will reduce the mechanical property of the samples, and it was reported from the earlier study, with the varied weight percentage of Bz of 6, 10, 14, and 18 [27].…”

Fused deposition models (FDMs) are the latest trends for constructing complicated and instinctive 3D printing. Polylactic acid (PLA) is the most widely used raw material in extrusion-based three-dimensional (3D) printing in many areas since it is biodegradable and environmentally friendly; however, its utilization is limited due to some of its disadvantages such as mechanical weakness and water solubility rate. To increase the mechanical properties of the FDM, nano bronze particles have been added as advanced research. Printing the hole less than a millimetre is complicated, and there is a limited report available in FDM. In this paper, polylactic acid (PLA) with a 14% bronze composite filament is made by hot extruding under the desired FDM conditions. The samples are built with 100% infilled density with 45° orientation to a sample size of 50 × 50 × 10 mm. To examine the printing state and the effect of microdrilling on the printed specimen, two different specimens are printed with and without holes. An industrial drill with specified feed, speed, and cutting width is used to perform the test. The size of the drilled hole is checked by scanning electron microscopy. The quality of the drilled hole and the wear of the tool is investigated and reported. According to the observation, it is noted that the secondary machining operation becomes unavoidable to have a hole of less than a millimetre. Machining, cutting speed, and feed speed influence the delamination zone and the circumference of the hole.

“…The drilling properties have been improved by the treated coir fiber used in the polyester composite [13]. The delamination and surface roughness of coir-fiber-reinforced polyester composite materials during the drilling processes have been minimized by optimizing the process parameters [14]. The delamination factor of coir-fiber polyester composite is comparatively lower than that of glass-fiber polyester composite material [15].…”

In this research, the hybrid natural fiber composite specimens were fabricated with a 64 wt.% epoxy resin matrix, 20 wt.% coir fiber, and 16 wt.% of various natural fibers by the hand-layup method. The influences of various natural fibers (Coir, Jute, Flax, Cotton, Human Hair, Sisal, Kenaf, and Calotropis) on the mechanical characteristics (tensile, flexural, and impact strengths) and drilling properties (delamination factor and ovality) of the Coir-fiber based hybrid composite have been investigated. The maximum tensile strength (48.15 MPa), maximum flexural strength (47.87 MPa), and maximum impact strength (2.85 kJ/m2) have been obtained by Coir/Flax, Coir/Sisal, and Coir/Hair Fiber hybrid composite materials, respectively. The minimum delamination factor (1.0) and ovality (169.4 µm) were obtained by coir/flax and coir/jute hybrid composite specimens when compared to other combinations of specimens. The delamination factor and ovality of the drilled hole of all combinations of hybrid composite specimens have been analyzed by scanning electron microscopy (SEM) images. The delamination factors of Coir/Flax and the drilling ovalities of Coir/Jute composite specimens are lower than those of other combinations of Coir-fiber-based composites.
