Design, Manufacturing and Characterization of Biodegradable Bone Screw from PLA Prepared by Fused Deposition Modelling (FDM) 3D Printing Technique

Bone tissue engineering provides the treatment possibility for segmental long bone defects that are currently an orthopedic dilemma. This review explains different strategies, from biological, material, and preparation points of view, such as using different stem cells, ceramics, and metals, and their corresponding properties for bone tissue engineering applications. In addition, factors such as porosity, surface chemistry, hydrophilicity and degradation behavior that affect scaffold success are introduced. Besides, the most widely used production methods that result in porous materials are discussed. Gene delivery and secretome-based therapies are also introduced as a new generation of therapies. This review outlines the positive results and important limitations remaining in the clinical application of novel bone tissue engineering materials and methods for segmental defects.

Additive manufacturing (AM) is a sustainable manufacturing approach because it can lower emissions and have a lower negative impact on the environment. 3D-printed interference screws from poly-lactic acid, eco-friendly filament, by fused deposition modelling (FDM), were fabricated with different process parameters. The most popular technique for reconstructing the anterior cruciate ligament is interference screw fixation. This study considered the role of the AM sustainability paradigm in terms of material input for FDM and product manufacturing. This study considered the role of the AM sustainability paradigm in terms of material input for FDM and process efficiency by investigating the effect of the AM process parameters, such as printing temperature (PT), printing speed (PS), and infill percentage (IP) on the density and stripping torque (ST). Later, the degradation profile of the screw was analyzed using the weight loss of screws. The experimental design of the fully factorial design was with two levels for each process parameter. The significant process parameters and their interactions were through statistical analysis of the resulting design. Results have shown that PT, PS, and IP significantly influenced the density and ST of 3D-printed interference screws. In five weeks, 3D-printed interference screws started to lose weight.
