Özet
Advancements in technology have led to the growing popularity of additive manufacturing (AM), commonly referred to as 3D printing. The Fused Deposition Modeling (FDM) method, alternatively known as Fused Filament Fabrication (FFF), involves the layer-by-layer melting of thermoplastic filaments to create 3D scaffolds or models. FDM is used more frequently than other methods due to its easy use and low cost. It finds extensive applications across diverse fields, including automotive, biomedical, aerospace, household and educational tools. Polylactic Acid (PLA) is commonly used in FDM 3D applications due to its structural properties such as low melting point, non-toxicity, non-irritation and good biological compatibility and has become more popular over time. PLA has become more popular due to its compatibility and the advantages it offers. However, although PLA has many advantages, it also has some disadvantages. One of the most significant drawbacks is its weak mechanical behaviour. Several research studies have been conducted to enhance the mechanical behaviour of these objects. These studies generally include the addition of another biomaterial, metal or composite to the structure of PLA, finding the optimum printing parameters (such as nozzle temperature, printing angle, printing density, layer thickness), selecting appropriate printing patterns and developing different unit cells. In recent times, there have been endeavors to adopt a fresh approach distinct from previous studies. The properties of PLA have been examined using different methods, comparative analyses have been conducted using various models and unit cells, scaffolds have been created by incorporating different materials into the structure of PLA and various analyses have been performed on these scaffolds. Recent studies conducted using novel methods are mentioned in this review article.
