The linear “take–make–dispose” model of plastic consumption has led to significant environmental challenges and unplanned waste legacies, emphasising the need for more sustainable recycling practices. This study explored integration post-consumer recycled polylactic acid (rPLA) into 3D printing filaments as a step towards manufacturing. Using 100% virgin PLA (vPLA) baseline, were produced with rPLA-to-vPLA ratios 0%, 25%, 50%, 75%, evaluated surface roughness, tensile strength, flexural properties, hardness. results revealed that increasing rPLA content negatively affects mechanical properties quality. Surface roughness increased from 7.06 µm pure vPLA 10.50 rPLA, whilst strengths decreased by 48.4% 49%, respectively, compared vPLA. Hardness also declined, showing 7.5% reduction relative Despite these reductions, blends up 50% retained over 90% performance vPLA, demonstrating viable compromise between sustainability. Morphological analysis highlighted poor interlayer adhesion void formation primary causes degradation in higher blends. challenges, this demonstrated rPLA-vPLA can extend life cycle promote manufacturing By addressing polymer research supports materials printing, contributing circular economy goals recycling, resource efficiency, production outcomes.

Additive manufacturing must be highlighted as an innovative technology with the capacity to produce objects complex and customized geometries using a diverse range of raw materials. Despite its significant potential, research compiling evaluating specific contributions additive in field chemical engineering was scarce both quantitative qualitative terms. Similarly, application tools has not been specifically reviewed. Therefore, this work conducted comprehensive review scientific literature covering these issues bibliometric analysis. The search encompassed entirety up year 2023, yielding 3761 documents Scopus database. principal findings analysis indicated exponential growth number publications, which suggests rising interest field. revealed that English dominant language documents, articles constituted most common document type, indicating quality maturity research. thematic distribution proved multidisciplinary, primary focus on materials science, well basic sciences. United States foremost contributor production, followed by China Germany. Keyword scrutiny cited enabled identification main topics, were found include biofabrication biomedical applications. Moreover, network software SciMAT (v 1.1.06) yielded corresponding strategic diagrams, evolution maps, networks, provided overview trends gaps. considerable other purposes overshadowed applications within field, while potential could make have eclipsed too. On one hand, focused process intensification benefit from design advanced microreactors miniaturized devices or more efficient heat exchangers, catalysts, adsorbents separation membranes structures. life cycle assessment optimization are established should extensively employed context ensure sustainable outcome.
