Algorithmic modeling and prototyping of a structural joint for freeform surfaces

2016

This paper describes a parametric approach in architectural design through the elaboration of a process for generating non-standard structural joints particularly suitable for the arrangement of freeform surfaces in which maximum adaptability of the system is required to join a different number of members converging in a node from generic directions. The algorithmic definitions, developed using the graphical editor Grasshopper integrated with Rhinoceros, allow the management of an integrated workflow from the conceptual design of freeform surface to the prototyping of a structural joint with 3D printing techniques.

Architettura di transizione. Im Printing 3D

2018

In recent years, the development of additive construction methods for the production of physical models starting from computerized ones has led to a return from the digital domain to the material one. A new "digital materiality" associated with 3D printing makes it possible to extend the imaginary of the contemporary architectural scene by consolidating the strong relationship between research and innovation. 3D printing is a rapid prototyping technique that allows the direct transposition of the digital model into its analogous material using a computer controlled nozzle to deposit small doses of material and compose the figure in space.

Redrawing the Past, reimaiging the Future. Gamification project for the reinterpretation of historical architecture

2021

The objectives of the work we present concern the reinterpretation of architectural traces of the past with a "gamification" project for educational laboratories to be activated in schools of different order and grade. The methodology used starts from the 3D-reconstruction of disappeared architectures, urban plots where the stratification lends itself to different interpretations, based on the documentary information found and the hypotheses that can be spent directly from reading the artefact. Then it translates everything into diversified outputs to tell the evolution of the monument and the site and its conjectural reconfiguration: from immersive 3D visualization to 3D printing of modula…

Formazione e trasformazione di un'immagine urbana. Ricostruzioni architettoniche tra l'asse della via Notarbartolo e il secondo tronco della via Libe…

2022

The contribution presented here is part of a work-in-progress project, which has as its focus the “extra-moenia” urban transformations suffered by the city of Palermo after World War II, with the aim of cataloging, reconstructing and restoring the remarkable heritage -lost in the years of the economic boom and building speculation- in three-dimensional virtual images. The analysis is part of the urban context affected by the extension of via Libertà starting from the intersection with via Notarbartolo, the transversal directional axis conceived in the Giarrusso Plan of 1887 as a connection to the Shipyards and built starting from the subdivisions of Villa Carini in the years 1891-1902. This…

Il contributo presenta un caso studio imprenditoriale rilevante dal punto di vista della disciplina urbanistica annoverabile come modello in funzione della possibile replicabilità e diffusione anche in contesti “isolati” come quello sicano. La scheda è parte di una raccolta di casi studio che dimostrano come nel territorio siciliano, "a fronte di un’inadeguatezza delle istituzioni a rispondere ai bisogni delle comunità locali e nonostante la progressiva perdita di capitale umano che impoverisce il dinamismo imprenditoriale, siano presenti germogli di innovazione e scintille di creatività da parte di soggetti protagonisti di piccole/grandi trasformazioni sociali, anche in contesti rurali e u…

Green composites for fertilizer controlled release produced by compression molding and FDM

2023

Excessive fertilization causes ecological problems due to leaching issues. To solve this problem and promote agriculture sustainability an innovative green composite for controlled release fertilizers was produced by adding NPK fertilizer flour to a biodegradable polymer with or without Opuntia Ficus Indica (OFI) particles. Six formulations were produced and employed for the fabrication of devices both for compression molding (CM) and fused deposition modeling (FDM). Both fillers displayed a good dispersion in the composites, excellent adhesion with the polymeric matrix and effectively acted as reinforcement. The decrease of NPK release rate (up to 30 days) was achieved using whole composit…

FINDUS: An Open-Source 3D Printable Liquid-Handling Workstation for Laboratory Automation in Life Sciences

2020

3D-printed laboratory devices can enable ambitious research purposes even at a low-budget level. To follow this trend, here we describe the construction, calibration, and usage of the FINDUS (Fully Integrable Noncommercial Dispensing Utility System). We report the successful 3D printing and assembly of a liquid-handling workstation for less than $400. Using this setup, we achieve reliable and flexible liquid-dispensing automation with relative pipetting errors of less than 0.3%. We show our system is well suited for several showcase applications from both the biology and chemistry fields. In support of the open-source spirit, we make all 3D models, assembly instructions, and source code ava…

Digital and handcrafting processes applied to sound-studies of archaeological bone flutes

2016

International audience; Bone flutes make use of a naturally hollow raw-material. As nature does not produce duplicates, each bone has its own inner cavity, and thus its own sound-potential. This morphological variation implies acoustical specificities, thus making it impossible to handcraft a true and exact sound-replica in another bone. This phenomenon has been observed in a handcrafting context and has led us to conduct two series of experiments (the first-one using handcrafting process, the second-one using 3D process) in order to investigate its exact influence on acoustics as well as on sound-interpretation based on replicas. The comparison of the results has shed light upon epistemolo…

Green Composites Based on Hedysarum coronarium with Outstanding FDM Printability and Mechanical Performance

2022

The addition of natural scraps to biodegradable polymers has gained particular interest in recent years, allowing reducing environmental pollution related to traditional plastic. In this work, new composites were fabricated by adding 10% or 20% of Hedysarum coronarium (HC) flour to Poly (lactic acid) (PLA). The two formulations were first produced by twin screw extrusion and the obtained filaments were then employed for the fabrication of composites, either for compression molding (CM) or by fused deposition modeling (FDM), and characterized from a morphological and mechanical point of view. Through FDM it was possible to achieve dense structures with good wettability of the filler that, on…
