Abstract

The demand for lightweight and mechanically reliable structures has motivated increased interest in Additive Manufacturing (AM), particularly Fused Filament Fabrication (FFF), while underscoring the importance of an integrated understanding of the design-to-fabrication workflow. While numerous studies have focused on individual aspects of the FFF process in fabrication of such structures, detailed review linking design strategies, optimization techniques, and manufacturing challenges are scarce. This work addresses that gap by reviewing current strategies for designing and fabricating lightweight structures using FFF. First, it investigates sophisticated design and optimization strategies, consisting of Design for Additive Manufacturing (DfAM) concepts and Topology Optimization (TO) techniques specifically adapted for thin-walled and lattice structures. The limitations of traditional CAD tools are extensively investigated along with a summary of major manufacturing challenges. The review combines multidisciplinary insights to create an integrated understanding for generating structurally efficient and reliable FFF components. It concludes by outlining prospective future research avenues, including artificial intelligence–driven process control and digital twins for predictive modeling. This work offers a detailed resource for researchers and practitioners aiming to address existing limitations and drive FFF towards resilient next-generation lightweight systems.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
