The waste of 3D printed plastic products is a matter of concern because of its impact on the circular economy. In this paper, we discuss the current status and problems of 3D printing, different methods of 3D printing, and applications of 3D printing. This paper focuses on the recycling and degradation of different 3D printing materials. 4D printing refers to single-material or multi-material printing of a device or object that can be transformed from a 1D strand into pre-programed 3D shape, from a 2D surface into preprogramed 3D shape and is capable of morphing between different dimensions. Such transformations are facilitated by, e.g., heating, light, or swelling in a liquid Modern 3D printing systems have become pervasive and widely used both in professional and in informal contexts, including sustainable-oriented ones. However, the risk to create very effective but non-sustainable solutions is very high since 3D printing systems could potentially increase the environmental emergencies and the unsustainable growth. In the transition process toward sustainable The 3D printing technology results to environmental impacts such as release of emissions and particulate matter, energy inefficiencies and production of recalcitrant wastes. The qualitative and quantitative assessment the impacts is not well understood. Energy consumption in 3D printing. Any industrial process requires energy to run, including 3D printing. From a sustainability standpoint, energy consumption rates directly correlate with environmental considerations, like CO2 emissions. 3D printing, particularly with metals, is by no means a low-energy technology. The environmental impact of 3D printing with recycled materials is examined through a sustainability analysis and a life cycle assessment of recycled 3D printed objects. The findings reveal significant benefits, including enhanced resource efficiency, waste reduction, and customisation possibilities. 5J1usv. Construction 3D printing is a method for printing concrete, polymer, metal, or other materials layer by layer using a 3D printer to create construction pieces or full buildings. The most prevalent form of the printer uses a robotic arm to extrude concrete back and forth. Advertisements. Powder binding and additive welding are two other 3D Regarding the social impact, Huang et al. (2013) have indicated that from a technical point of view, 3D printing could have a positive impact on society, through the production of personalized health products that could improve people’s health and quality of life, through a reduction in environmental impact, and through a simplification of As the world embraces additive manufacturing, also known as 3D printing, concerns about energy consumption and environmental impact have become increasingly prevalent. While 3D printers offer innovative solutions and exciting possibilities, it is essential to examine their electricity usage to assess their overall sustainability. Conclusions. Overall, 3D printing can provide time and cost savings to ecologists, and with recent advances in less toxic, biodegradable, and recyclable print materials, ecologists can choose to minimize social and environmental impacts associated with 3D printing. www.xtreee.com.

The wall system Using computer-aided design, 3D printing builds an item up layer by layer in a very precise fashion. Initially, plastics and metal powders were used as the feedstock for the process, but now resins, carbon fibers, and even graphite and graphene are widely used too. The technique has many advantages over traditional manufacturing methods: it
