The study investigates the motivations, learning experiences and impacts of Chilean student mobility in China, focusing on postgraduate students. It analyzes how this education has influenced their professional trajectories and Sino-Chilean relations.

The methodology employs a qualitative approach, based on 13 semi-structured interviews, with an analysis covering aspects such as the reasons for studying in China, the acquisition of Mandarin Chinese, the academic experience and professional projections.

The research concludes that these students, trained in China, significantly contribute to strengthening bilateral ties in various fields, highlighting cultural diplomacy as a key factor in expanding collaboration between the two countries.

Additionally, it underscores the need to consider student mobility as an essential component of relations between Chile and China, in particular, and among different Global South countries in general, transcending the limitations of financing criteria and the Eurocentric orientation that predominates in the internationalization policies of Chilean higher education.

This papers aims to study lattice structures in terms of geometric variables, manufacturing variables and material-based variants and their correlation with compressive behaviour for their application in a methodology for the design and development of personalized elastic therapeutic products.

Lattice samples were designed and manufactured using extrusion-based additive manufacturing technologies. Mechanical tests were carried out on lattice samples for elasticity characterization purposes. The relationships between sample stiffness and key geometric and manufacturing variables were subsequently used in the case study on the design of a pressure cushion model for validation purposes. Differentiated areas were established according to patient’s pressure map to subsequently make a correlation between the patient’s pressure needs and lattice samples stiffness.

A substantial and wide variation in lattice compressive behaviour was found depending on the key study variables. The proposed methodology made it possible to efficiently identify and adjust the pressure of the different areas of the product to adapt them to the elastic needs of the patient. In this sense, the characterization lattice samples turned out to provide an effective and flexible response to the pressure requirements.

This study provides a generalized foundation of lattice structural design and adjustable stiffness in application of pressure cushions, which can be equally applied to other designs with similar purposes. The relevance and contribution of this work lie in the proposed methodology for the design of personalized therapeutic products based on the use of individual lattice structures that function as independent customizable cells.
