The urgency of climate change has highlighted the need for sustainable road construction materials, replacing the conventional asphalt, which significantly contributes to global warming and the urban heat island effect. With this in mind, the construction of the world’s first 30-m plastic road in Zwolle, Netherlands, in 2018, opened the door for novel plastic applications as paving materials 3. Testing setups in published studies. This chapter will give an overview of the different test setups used in the studies analyzing the emissions of FFF 3D printers and 3D printing pens. We will present the different test environments and settings, measurement instruments, printing conditions and calculation models. 3D printing can have a positive impact on the environment: it reduces manufacturing waste, lowers the carbon footprint and supports the circular economy. The European Commission has been called on Future-proofng features of 3D printing include its low environmental impact and ability to produce complicated parts for relatively little money, even with minimal postprocessing. Other In this study, the environmental performance of a 3D printing system is evaluated in order to quantify the parameters for sustainable design strategies. A sinusoidal wall system has been selected as a case study. A cradle-to-gate life cycle analysis of a system has been performed, and a specific focus on the footprint of robotic 3D printing We can see that the 3D printing scenario shows a lower environmental impact in all indicators, with a reduction in impact ranging from 24% in mineral extraction to 81% in aquatic eutrophication. The inclusion of results at endpoint level is useful to identify those impact indicators where the system has the highest contribution to environmental 3D printing is a process of making three-dimensional objects layer by layer using computer-created files. It is a quite new building technique, especially in the construction sector. The aim is to improve efficiency and reduce the environmental impacts of the sector. The innovative approach of 3D printing in the sector is combining traditional 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. pwJwQ.
