AbstractPolylactic acid (PLA) is one of the most commonly used materials in the biomedical sector because of its processability, mechanical properties and biocompatibility. Among the different techniques that are feasible to process this biomaterial, additive manufacturing (AM) has gained attention recently, as it provides the possibility of tuning the design of the structures. This flexibility in the design stage allows the customization of the parts in order to optimize their use in the tissue engineering field. In the recent years, the application of PLA for the manufacture of bone scaffolds has been especially relevant, since numerous studies have proven the potential of this biomaterial for bone regeneration. This review contains a description of the specific requirements in the regeneration of bone and how the state of the art have tried to address them with different strategies to develop PLA-based scaffolds by AM techniques and with improved biofunctionality.

Material engineers continuously make every effort for the evolution of novel and prevailing production performances to supply our biosphere with resource-proficient, economical, and hygienic substances with superior package operation. The mitigation of energy depletion and gas releases as an utmost significance worldwide is a renowned datum; which also needs the improvement of delicate substances employing budget-proficient and ecologically pleasant methods. Consequently, copious exploration has been aimed in the study of methods retaining a potential to wrestle these widespread essentials. Material engineering processes have advanced as a feasible substitute for conventional steel fragment construction methods. CE has experienced an extraordinary advancement throughout the previous three decades. It was originally utilised uniquely as a state-of-the-art reserve of the paradigm. Referable to the expertise development which permits merging countless engineering procedures for the output of a modified portion that employed intricate configurations, CE expertise has got cumulative responsiveness. As such, this article intends to furnish a comprehensive appraisal of chemical fabrication progressions for steel substance evolution utilised in different applications. The inspection encompasses the current advancement of CE know-hows, a detailed taxonomy and classification of manufacturing operations. The focal point of the upcoming perspective of CE in substance investigation and application is further deliberated
