TL;DR: This paper aims to examine the current advances on thermoplastic recycling processes via additive manufacturing technologies using the scopus, web of science and springer databases to validate the technical feasibility, environmental impact, and economic viability of the proposed closed recycling global chain for DRAM.

TL;DR: In this paper, a general methodology to evaluate the recyclability of thermoplastics used as feedstock in open-source 3D printing machines is proposed, and the proposed methodology is applied to the recycling study of polylactic acid (PLA) material addressed to the fused filament fabrication (FFF) technique.

TL;DR: This article explores the economic and environmental feasibility of this distributed plastic recycling approach from a logistics perspective, as a step towards its validation, using an optimization mixed integer linear programming model as an evaluation tool.

TL;DR: In this article, a geometrical benchmarking model (GBM) is used to evaluate the accuracy of open source 3D printers based on fused deposition modeling (FDM) and root-mean-square deviation (RMSD) values are employed as an accuracy estimator.

TL;DR: Fused filament fabrication (FFF) is the most common and widespread additive manufacturing (AM) technique, but it requires the formation of filament as mentioned in this paper, which is not suitable for many applications.
