“…Therefore, ABS resin is widely used in electronic and electrical appliances, automobile and other daily necessities, and industrial products manufacturing. However, the friction and wear resistance of ABS resin is limited and the friction coefficient is large [ 4 ]. On the other hand, it is urgent to have better mechanical properties [ 5 ].…”

In this manuscript, the graphene oxide (GO) was modified by hyper-branched polyester (HBP). The effects of GO or modified GO (HBP-m-GO) on the mechanical performance and wearing properties were investigated. The results of X-ray photoelectron spectra (XPS), Fourier transform infrared spectroscopy (FT-IR), and transmission electron microscopy (TEM) revealed the successful grafting of HBP onto GO. The thermogravimetric analysis (TGA) indicated that the graft amount of HBP is calculated to be 9.6 wt%. The GO or HBP-m-GO was added into acrylonitrile-butadiene-styrene copolymer (ABS) to prepare the ABS/GO composites. The mechanical properties and wear performance of the composites were studied to comparatively study the impact of GO modification on the properties of the composites. The results revealed that the addition of GO has a significant effect on the mechanical properties of ABS, and when HBP-m-GO was added, the elastic modulus and tensile strength of ABS/HBP-m-GO increased evidently compared with ABS/GO. The tensile strength increased from 42.1 ± 0.6 MPa of pure ABS to 55.9 ± 0.9 MPa, up to 30%. Meanwhile, the elongation at break was significantly higher than ABS/GO to 20.1 ± 1.3%, slightly lower than that of pure ABS. For wear performance, the addition of raw GO decreased the friction coefficient, and when the HBP-m-GO was added, the friction coefficient of the ABS/HBP-m-GO dropped more evidently. Meanwhile, the weight loss during the wear test decreased evidently. The related mechanism was discussed.

“…The life cycle assessment results indicated that closed-loop recycling of PLA has a lower environmental impact than incineration or landfilling. In addition, Goutham et al (2018) investigated the mechanical properties of test specimens molded by FFF using filaments consisting of blends of recycled and virgin ABS (20 m–50 m per cent of recycled content). These authors observed that increasing the amount of recycled ABS reduced the tensile strength of the plastic parts.…”

Purpose This study aims to evaluate and compare the macroscopic properties of commercial acrylonitrile-butadiene-styrene (ABS) processed by two different types of additive manufacturing (AM) machines. The focus is also on the effect of multiple closed-loop recycling of ABS. Design/methodology/approach A conventional direct-drive, Cartesian-type machine and a Bowden, Delta-type machine with an infrared radiant heating system are used to manufacture test specimens molded in ABS. Afterward, multiple closed-loop recycling cycles are conducted, involving consecutive AM (four times) and recycling (three times). The rheological, mechanical, morphological and physicochemical properties are investigated. Findings The type of machine affects the quality of the produced parts. The machine containing an infrared radiant system in a temperature-controlled chamber produces parts showing higher mechanical properties and filling fraction, although it increases the yellowing. Closed-loop recycling of ABS for AM is applicable for at least two cycles, inducing a slight increase in tensile modulus (ca. 5%) and in tensile strength (ca. 13%) and a decrease in the impact strength (ca. 14%) and melt viscosity. An increase in the filling fraction of the AM parts promotes an increase in tensile strength and tensile modulus, although it does not influence the impact strength. Furthermore, multiple closed-loop recycling does not affect the overall chemical structure of ABS. Practical implications Controlling the environmental temperature and using infrared radiant heating during AM of ABS improves the quality of the produced parts. Closed-loop recycling of ABS used in AM is feasible up to at least two recycling steps, supporting the implementation of a circular economy for polymer-based AM. Originality/value This study shows original results regarding the assessment of the effect of different types of AM machines on the main end-use properties of ABS parts and the influence of multiple closed-loop recycling on the characteristics of ABS fabricated by the most suited AM machine with an infrared radiant heating system and a temperature-controlled environment.

In this paper, the authors propose a novel strategy of 2D scanning that might be adapted for any additive manufacturing process. The featured novelty corresponds to a Skeleton Based Perpendicularly (SBP) of the 2D shape of each slice. Thus, it is proposed to minimize the total production time of a given layer under some constraints. In other word, it is proposed to study the competitiveness conditions of the new scanning technique regarding the classical chess scanning strategy from a productivity perspective. In order to introduce this new technique, the paper treats the case of a rectangular layer. The competitiveness of the proposed technique was discussed according to chess decomposition parameters, the hatch space distance, and the dimensions of the primitive rectangle layer to analyze. The indicators introduced corresponds to “the gain of production time” and “the specific gain of production time per surface unit”; then, these latter were computed and discussed in two separated cases of study. The findings show that, by the adoption of the SBP technique instead the chess scanning strategy, it is possible to save about 3% to 45% of production time gain for the first case of study. The gain of production time per surface unit was analyzed in the second case of study. The correspondent analysis permitted to highlight the percentage of gain of time related to the area to scan. Indeed, the gain per surface unit varies between 4.32×10-6%/mm2 and 6.96×10-05%/mm2. In one hand, these indicators depend linearly on the decomposition strategy of the central area of the SBP technique and also according to the rectangle dimensions. In addition, for the lowest values of hatch space, around 25µm, the two techniques in competition present quasi-similar production time, where the variations between them is minimal. Nevertheless, starting from 65µm, the SBP scanning strategy present considerable less time of production judged as exponentially decreasing according to the hatch space distance. Finally, one can see that the scanning model proposed could present major contributions in other scientific and technical fields that use surface control as territorial security, water adduction and distribution, telecommunication, etc. by varying and adapting the decision variables according to each field of study.
