This study aims to evaluate the impact breaking energy of the parts manufactured by the fused filament fabrication (FFF) method. The evaluation considers the use of the epoxy resin coating, different materials and different printing orientations.

The authors developed an experimental statistical design using 54 experimental trials. The experiments’ output variable is the impact break energy of the parts manufactured by the FFF method. The input variables for the experiments consist of an epoxy resin coating (XTC-3D®, generic resin and without resin coating), different filament materials (nylon + carbon fiber, polyethylene terephthalate and polycarbonate) and different printing orientations (flat, edge and vertical) used. The authors carried out the tests following the EN ISO 179-1.

The use of resin coating has a significant influence on the impact energy of parts manufactured using the FFF method. The resin coating increases the impact resistance of parts processed by FFF by almost 100% of the value as compared to the parts without a resin coating. Post-processing is useful on ductile materials and increases impact breaking energy at weak print orientations.

This research opens a new opportunity to improve the mechanical properties of parts manufactured using the FFF method. The use of a resin coating reinforces the parts in weak print orientation.

The purpose of this paper is to identify in the specialized literature published in the past 20 years about sales training, some elements or key factors that could be applied to the use of information and communication technologies (ICT) as a support for the learning of the detection of business opportunities.

This is a study of a documentary nature in which a method of systematic literature review was applied to 132 studies published in journals indexed in Scopus and Scielo on sales training processes. The analysis of the data combined a process of categorization and frequencies statistical analysis.

The results highlight the role of ICT and specifically the use of mobile devices to support the strengthening of training in sales in terms of relationship, opportunity and flexibility in communication with the client, the construction of positive emotional environments and experiential/situated training.

The originality of this study lies in the extraction and interpretation of key factors focused on addressing a guiding question about the relationships between the use of ICT and sales training.
