InDeSIS: opportunities, value and benefts
Sampaio, Álvaro M.Collaborative projects in design education are essential in preparing students for the evolving demands of the global design industry. The InDeSIS project (Erasmus+ BIP) brought together product design students from four Higher Education Institutions (HEIs) to explore Design for Inclusion and Design for Sustainability through a blended teaching strategy. This initiative fostered cross-institutional collaboratio...
From prototypes to end user products through additive manufacturing
Sampaio, Álvaro M.; Almeida, José Carlos Ferreira; Pontes, A. J.This paper challenges the notion that Additive Manufacturing (AM) is limited to prototyping by demonstrating its signifcant role in fnal product development. Through its ability to create complex geometries, optimize material usage, and consolidate parts, AM has evolved into an efective strategy for producing functional end-use products. The incorporation of Design for Additive Manufacturing (DfAM) principles e...
Cradle-to-gate life cycle assessment: a comparison of polymer and metal-based p...
Anwar, Talha; Lopes, Ana Carina Ferreira; Silva, Eva C.; Mould, Sacha Trevelyan; Sampaio, Álvaro M.; Pontes, A. J.Diferent industries are adopting additive manufacturing (AM) technologies to produce complex designs with minimum material wastage. The sustainability assessment of AM technologies is therefore essential to address the current environmental challenges. This research aims to compare the environmental impacts of diferent raw materials used for the production of a robot end-efector with internal conformal channels...
Evaluation of AlSi10Mg injection moulding inserts with conformal cooling channels
Silva, Eva C.; Rodrigues, Sérgio José Ferreira; Rodrigues, Hugo Luís Leitão Teixeira; Fernandes, Leandro Cunha; Silva, Cátia Samanta RibeiroPurpose This paper aims to investigate and compares the performance of mould inserts with conformal cooling channels (CCC), fabricated via additive manufacturing (AM), and conventional cooling systems, both made from aluminium alloys. The comparative analysis encompasses simulation results, critical manufacturing considerations and part quality, focusing on warpage and crystallinity. Design/methodology/approach...
Influence of layer thickness on dimensional and geometrical properties of alumi...
Silva, Eva C.; Lopes, Ana Carina Ferreira; Sampaio, Álvaro M.; Pontes, A. J.To ensure dimensional repeatability of additively manufactured parts, it is crucial to evaluate their dimensional and geometrical properties and to determine the capabilities of these systems to produce certain features. In this sense, the purpose of this research is to understand the influence of the layer thickness on the dimensional and geometrical accuracy of parts produced by powder bed fusion–laser beam. ...
Development and characterization of composite materials with multi-walled carbo...
Lopes, Ana Carina Ferreira; Sampaio, Álvaro M.; Pontes, A. J.Purpose: With the technological progress, high-performance materials are emerging in the market of additive manufacturing to comply with the advanced requirements demanded for technical applications. In selective laser sintering (SLS), innovative powder materials integrating conductive reinforcements are attracting much interest within academic and industrial communities as promising alternatives to common engi...
Design and development of urban space products by large-scale robotic extrusion...
Santos, Afonso Henrique Freitas Ferreira; Sampaio, Álvaro M.; Costa, Artur José Teixeira; Pontes, A. J.The production of products in additive manufacturing systems through the extrusion of material using robotic arms requires new paradigms ranging from product design, material selection, material processability, communication with the production system, production control, etc. The development of products through these technologies allows the production of solutions of considerable scale and innovation. These ap...
Design and industrial implementation of a multi-functional part produced by pow...
Lopes, A. C.; Sampaio, Álvaro M.; Fernandes, F.; Vaz, P. M.; Pontes, A. J.The use of robot end-effectors programmed to perform handling tasks in industrial environments has expanded in several sectors as a consequence of the rapid digital transformation seen in recent years. With such growing demands, additive manufacturing is evolving in the robotics field with more efficient, innovative, and customer-specific solutions owing to its design flexibility. Thus, this work presents a rob...
Design of nozzles for surface mount technologies produced by additive manufactu...
Sampaio, Álvaro M.; Miranda, Ana C.; Pontes, A. J.The increasing use and production of electronic systems, equipped with multiple PCBs, leads to constant development in manufacturing technologies. A predominant choice in PCB production is Surface Mount Technology (SMT). The most important phase of the SMT process is the pickup and placement step, where nozzles, specific to the electronic component, are responsible to pick components and place them on the PCB. ...
Design and development of an Automatic Optical Inspection (AOI) system support ...
Sampaio, Álvaro M.; Lima, André; Silva, Cátia Samanta Ribeiro; Carneiro, Vítor H.; Fernandes, Fábio; Fernandes, André; Pontes, A. J.Visual inspection of components, subassemblies and final products is an essential step to ensure the quality control of ready-to-market electronic components. In many manufacturing plants, including Bosch Car Multimedia S.A., typically automated systems for automatic optical inspection (AOI) are implemented at several workstations to perform visual verification and validation in between critical production task...
