“…Afrose et al [28] proposed a study about the fatigue characteristics of PLA parts processed through FDM. Similar studies about the fatigue behavior of polymeric FDM printed parts were also proposed in [29,30]. Torres et al [31] investigated the influences of printing parameters on the material properties of FDM printed PLA components tested in torsion.…”

In this paper, polymeric specimens are produced via the Fused Deposition Modelling (FDM) technique. Then, experimental tensile and compression tests are conducted to evaluate the main mechanical properties of elements made of PolyLacticAcid (PLA) material. A standardized characterization test method for FDM 3D printed polymers has not been developed yet. For this reason, the ASTM D695 (usually employed for polymers produced via classical methods) has been here employed for FDM 3D printed polymers after opportune modifications suggested by appropriate experimental checks. A statistical analysis is performed on the geometrical data of the specimens to evaluate the machine process employed for the 3D printing. A capability analysis is also conducted on the mechanical properties (obtained from the experimental tests) in order to calculate acceptable limits useful for possible structural analyses. The Young modulus, the proportional limit and the maximum strength here defined for PLA specimens allow to confirm the different behavior of FDM printed PLA material in tensile and compressive state. These differences and the calculated acceptable limits for the found mechanical properties must be considered when this technology will be employed for the design of small structural objects made of PLA, as in the present study, or ABS (Acrilonitrile Butadiene Stirene). From the statistical and capability analysis, the employed printing process appears as quite stable and replicable. These types of research together with other similar ones that will be conducted in the future will allow to use polymeric materials and the FDM technique to produce small structural elements and also to carry out the appropriate verifications.

Aluminum-plastic packaging is a multilayer material composed of polymer and aluminum, which has been applied in food, medical, and other fields, due to the excellent fresh-keeping and barrier performance. However, it is difficult to recycle aluminumplastic packaging waste (APPW) due to the complicated components and the low value of reclaim products. This paper reports a green way to recycle the APPW by solid-state shear milling (S 3 M) technology and then fabricate APPW/expandable graphite (EG) composite parts with high thermal conductivity by fused deposition modeling (FDM) process. After the S 3 M treatment, the ultrafine APPW powder with the size of 7 $ 8 um was obtained, and it showed excellent processibility and the APPW/EG composite parts were successfully processed by FDM technology. The APPW/EG three-dimensional (3D) printed parts showed excellent mechanical and heat transfer performance along the stretch direction (0 ), where the tensile strength and thermal conductivity reached 13.58 MPa and 2.71 W/mK for APPW/EG (80/20) composites, respectively, much higher than those of pure APPW composite (7.71 MPa and 0.62 W/mK). Theoretical calculations showed that the interfacial thermal resistances of APPW/EG 3D printed parts with aligned fillers were lower than other samples. Furthermore, the APPW/EG composites with 20 wt.% EG loading showed a low electrical conductivity of 10 −10 S/cm because the oxidation layer was formed on the surface of Al flakes during the S 3 M process, which can be used in the thermally conductive insulating field. The new strategy presented in this work provides a new sight to recycle APPW for value-add material.

“…The idea of optimizing 3D printing is central to the development of this group of technologies by relying on new printing technologies, new mechanical properties of materials, and automation of their use in 3D printing (including multi-material printing) [ 13 ]. Automation allows for more accurate consideration of input parameters and requirements for printed object properties and applications [ 14 ].…”

Optimization of Extrusion-Based 3D Printing Process Using Neural Networks for Sustainable Development

Technological and material issues in 3D printing technologies should take into account sustainable development, use of materials, energy, emitted particles, and waste. The aim of this paper is to investigate whether the sustainability of 3D printing processes can be supported by computational intelligence (CI) and artificial intelligence (AI) based solutions. We present a new AI-based software to evaluate the amount of pollution generated by 3D printing systems. We input the values: printing technology, material, print weight, etc., and the expected results (risk assessment) and determine if and what precautions should be taken. The study uses a self-learning program that will improve as more data are entered. This program does not replace but complements previously used 3D printing metrics and software.
