“…There was an overall improvement in flexural strength due to better stress transfer between the matrix and fibers. Reyna et al 22 investigated the effect of layer height, infill pattern, infill density, and raster angle on the tensile behavior of MEX-fabricated Nylon-CF, ABS, and PLA samples. The results showed that the layer height and infill density were significant factors in tensile behavior: the lower layer height and higher infill density resulted in better tensile strength.…”

Nylon-CF is an important thermoplastic 3D printable material that can be used to develop high-quality functional parts with slight modifications in low-cost machines like material extrusion (MEX) technology. This paper investigates the tensile behavior of Nylon-CF samples produced by material extrusion. The influence of seven process parameters is studied on response characteristics. The Taguchi design is used to investigate the effect of process parameters on Young’s modulus and yield strength of specimens fabricated as per ASTM D-638. A two-level fractional factorial design supplements the L27 design results. The results show that the layer height, infill pattern, density, and raster angle significantly affect the tensile behavior. The apparent Young’s modulus is also significantly affected by the interaction between layer height, infill pattern, and infill density.

A continuous polyglycolic acid (PGA) fiber-reinforced polylactic acid (PLA) degradable composite was proposed for application in biodegradable load-bearing bone implant. The fused deposition modeling (FDM) process was used to fabricate composite specimens. The influences of the printing process parameters, such as layer thickness, printing spacing, printing speed, and filament feeding speed on the mechanical properties of the PGA fiber-reinforced PLA composites, were studied. The thermal properties of the PGA fiber and PLA matrix were investigated by using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The internal defects of the as-fabricated specimens were characterized by the micro-X-ray 3D imaging system. During the tensile experiment, a full-field strain measurement system was used to detect the strain map and analysis the fracture mode of the specimens. A digital microscope and field emission electron scanning microscopy were used to observe the interface bonding between fiber and matrix and fracture morphologies of the specimens. The experimental results showed that the tensile strength of specimens was related to their fiber content and porosity. The printing layer thickness and printing spacing had significant impacts on the fiber content. The printing speed did not affect the fiber content but had a slight effect on the tensile strength. Reducing the printing spacing and layer thickness could increase the fiber content. The tensile strength (along the fiber direction) of the specimen with 77.8% fiber content and 1.82% porosity was the highest, reaching 209.32 ± 8.37 MPa, which is higher than the tensile strength of the cortical bone and polyether ether ketone (PEEK), indicating that the continuous PGA fiber-reinforced PLA composite has great potential in the manufacture of biodegradable load-bearing bone implants.

“…For 3D printing of continuous fiber-reinforced thermoplastic resin composites, the resin and continuous fiber are separately fed into the extrusion device for in situ-impregnating, and then the impregnated fiber is deposited on a working platform for printing. Continuous fiber reinforced polylactic acid (PLA), [10][11][12] polyamide (PA), 13,14 and acrylonitrile-butadiene-styrene copolymer (ABS) 15,16 have been prepared successfully based on the above-mentioned method. However, there is still a gap between 3D printing and traditional molding methods in mechanical properties.…”

The interfacial bonding strength of the 3D‐printed composites was poor due to the inadequate impregnation. To improve the interfacial performance and mechanical properties of the 3D‐printed composites, carbon fiber (Original‐CF) was modified by oxidation combined with sizing, to obtain Sized‐CF, and continuous carbon fiber‐reinforced phenolic resin (Original‐CF/PF and Sized‐CF/PF) composites were fabricated via in situ‐curing 3D printing. The impregnation nozzle diameter influences the resin content and the impregnation effect of the resin into the fiber bundles. Mechanical properties with different impregnation nozzle diameters of Sized‐CF/PF composites all increased compared to that of Original‐CF/PF composites. The flexural strength of Sized‐CF/PF composites increased by 15.3% and interlaminar shear strength increased by 28.6%, compared to that of Original‐CF/PF composites, when the impregnation nozzle diameter was 0.40 mm. The fiber‐resin interface and the effect of interfacial performance on fracture mode of the composites were investigated systematically. The interfacial performance was improved, owing to the decrease of void defect volume and the increase of impregnation uniformity between the fiber and resin interface; the fracture mode was transferred from longer fiber pulling‐out for Original‐CF/PF composites to shorter fiber pulling‐out for Sized‐CF/PF composites, owing to the improvement of interfacial performance.Highlights Carbon fiber was modified to improve interfacial and mechanical properties. Nozzle diameter of 0.4 mm obtains adequate resin content and extrusion force. Defect volume reduced and impregnation uniformity improved after modification. Flexural strength of the composite increased by 15.3% after CF modification.
