“…It is important to note that the proposed environmentally friendly 3D optical verification technology can be employed for plastic products made of acrylonitrile butadiene styrene or polycarbonate [ 25 , 26 , 27 , 28 , 29 ]. In addition, the proposed environmentally friendly 3D optical verification technology can also be employed in the verification of feature sizes in the plastic injection mold [ 30 ], stamping die, blow molding mold [ 31 ], rotational molding mold, metal injection mold [ 32 , 33 ], or transfer molding mold [ 34 ]. In practical experience, three kinds of objects are difficult to scan.…”

Nowadays, the optical measuring approach is widely used in the precision machining industry due to high measurement efficiency. In the industry, measuring devices play a crucial role in the field of quality assurance. In practical engineering, the green measurement approach indeed plays an important role in the industry currently. In this study, a state-of-the-art green technique for three-dimensional (3D) optical measurements without environmental pollution is demonstrated, which is an environmentally friendly optical measurement method. This method can perform precise optical measurement without matte coatings. This work dealt with the possibility of measuring four metal components that were not sprayed with anything. The differences in the optical measurement results between with and without matte coatings were investigated and analyzed. It was found that the research result has practical value in the precision machining industry because average size errors of the four measurement objects with different surface properties can be controlled at about 3 µm, 0.1 µm, 0.5 µm, and 9 µm. A technical database with industrial value was established for optical measurements of metal components with different surface properties without matte coatings, which can serve as an alternative to the conventional 3D optical measurement.

“…Metallic powders, such as copper powder [ 50 ] or aluminum powder [ 51 ] can also be added in the manufacturing process to improve the physical properties of the fabricated filament. In addition, some reinforcing fillers, such as silicon carbide, aluminum oxide, molybdenum disulfide [ 52 , 53 , 54 ], zirconia [ 55 , 56 , 57 ], or silicon nitride [ 58 , 59 , 60 ] can also be mixed into the recycled PLA materials to develop filaments with high wear resistance [ 61 ] to enhance the life of direct soft tooling built with filaments [ 62 , 63 , 64 ].Therefore, the filament with both excellent mechanical and physical properties can be employed to fabricate rapid tooling [ 65 ] for thermoforming, blow molding [ 66 ], plastic injection molding [ 67 , 68 ], rotational molding, or transfer molding. These issues are currently being investigated and the results will be presented in a later study.…”

The amount of wasted polylactic acid (PLA) is increasing because 3D printing services are an increasingly popular offering in many fields. The PLA is widely employed in the fused deposition modeling (FDM) since it is an environmentally friendly polymer. However, failed prototypes or physical models can generate substantial waste. In this study, the feasibility of recycling PLA waste plastic and re-extruded it into new PLA filaments was investigated. An automatic PLA filament extruder was first developed for fabricating new PLA filaments. This paper also discusses the process, challenges, and benefits of recycling PLA waste plastic in an effort to fabricate new PLA filaments more sustainable. It was found that it was possible to fabricate PLA filament using recycled PLA waste plastic. The production cost is only 60% of the commercially available PLA filament. The tensile strength of the developed PLA filament is approximately 1.1 times that of the commercially available PLA filament. The design of experiments approach was employed to investigate the optimal process parameters for fabricating PLA filaments. The most important control factor affecting the diameter of PLA filament is the barrel temperature, followed by recycled material addition ratio, extrusion speed, and cooling distance. The optimal process parameters for fabricating PLA filament with a diameter of 1.7 mm include the barrel temperature of 184 °C, extrusion speed of 490 mm/min, cooling distance of 57.5 mm, and recycled material addition ratio of 40%.

The manufacture of polyethylene terephthalate (PET) containers is now very common, but there has been little research on energy saving in this manufacturing technique. This paper provides a feasible, simple, and low-cost energy-saving manufacturing technology for injection stretching blow molding (ISBM). This study is divided into two parts: an experimental part and a computational part by computational fluid dynamics (CFD). The principle and execution methods of the experiment and computation are delineated in the text. Sensor detection is used to confirm the result of CFD. The finished product produced by the proposed technique has a higher quality than a product made in a factory and the energy saving was approximately 14%. In the future, we will continue to study the integration of various technical details so that machine operators can better understand the methods of energy-saving operation and thereby contribute to environmental protection simultaneously.
