This paper aims to evaluate the evolution of the organizational field in the Colombian coffee industry between 1960 and 2020 and explain how peripheral actors influenced institutional change.

The methods analyze historical processes from a hermeneutical and interpretative perspective. The authors used data collection techniques through interviews, archive data, publications and media reports, embracing an interdisciplinary and qualitative documentary approach. This approach helps the authors unravel the temporal dimensions of the historical discourse related to coffee and the involvement of various actors within organizational structures.

The authors found that, unlike the literature regarding the change in organizational fields, recently, within the coffee sector in Colombia, the institutional work of peripheral actors (small producers, local associative groups and coffee women, among others) is changing the field as follows: (1) women are changing traditional behaviors moving from hierarchical family structures and lack of gender awareness, to empowered, horizontal and sustained relationships, (2) indigenous people include rituals and other traditional practices in coffee production and (3) ex-guerrilla members are helping to strengthen the peace process implementation in Colombia through coffee production.

The authors did not conduct statistical or computational analysis to simulate the emergence of new organizational forms. Instead, the authors attempted to elucidate narratives and discourses that reflect the tensions between central and peripheral actors from a historical perspective.

This study seeks to help leaders and managers overcome processes or organizational change in which peripheral actors are crucial. From that perspective, allocating resources and capabilities can become more effective.

This paper offers a new perspective of change within organizational fields from the roles of peripheral actors, which are fundamental in change processes within organizational fields, especially in the global south, where tensions between elites and vulnerable people are familiar.

The purpose of this paper is to characterize a new structural bi-matirial (scaffold and filler).

The bi-matirial has been obtained by means of an additive manufacturing system consisting of a fused filament fabrication extruder head and an epoxy resin depositor head. The new bi-matirial will consist of a thermoplastic material that will serve as the main structure and an epoxy resin that will serve as a filler and adhesion between layers. The creation of this new bi-matirial will improve the physical–chemical and mechanical properties with respect to the thermoplastic material. This paper will focus on the impact behavior of IZOD and the impact behavior of punctures.

The new polylactic acid (PLA) and epoxy bi-matirial allow improvements in toughness and puncture impact resistance compared to the PLA thermoplastic. This increase in toughness is between 20% and 30% depending on the orientation of the print. In the same way, the energy absorbed in the puncture impact test has been increased by 42%–48%.

The improvement in the impact absorption capacity of this new bi-matirial makes it ideal for the manufacture of medical parts in which customization, lightness and impact resistance are their main characteristics such as sports protection systems.

The originality of creating parts through additive manufacturing that combines a material generated with cold extrusion, such as epoxy resin and a material generated with hot extrusion, such as thermoplastics, lies in the unique synergy that this mixed and simultaneous technique offers. By uniting these two manufacturing methods, it allows the exploration of new physical and chemical properties in the resulting parts, taking advantage of the individual advantages of each material. This combination opens the door to the creation of components with a wider range of characteristics, from strength and durability to flexibility and temperature resistance, thus offering innovative and versatile solutions for various applications in fields such as engineering, medicine and design.
