Abstract

The new emerging generation of microsystems represents a major opportunity for a substantial EU economic growth, in anindustry counting already more than 200.000 workers and a turnover in 2019 of €450 billion. The Mesomorph conceptprovides the means to overcome the following 4 main hurdles:1. The intrinsic physic of microsystems doesn’t allow the simple downsizing of conventional technologies toindustrialize micromanufacturing processes. Mesomorphallows to limit the number of micromanipulation tasks by integratingan all-in-onemachine featuring novel processes for the direct creation of functions (electronic, fluidic, optic) directly on asubstrate, with a RESOLUTION down to 300nm, by combining multi-material addition (Two-Photon Polymerization, AtomicLayer 3D nano printing) and subtraction (Femtolaser micro-ablation) in a self-contained white room.2. Because of the intrinsic slowness of physical processes at microscale, productivity cannot be achieved bysequencing multiple single steps. Mesomorph proposes a scaleup throughput by PARALLELIZATION and batch processingUP TO 50k PARTS/YEAR, leveraging a new multiple micronozzles system to extend the SADALP working area from10x10mm up to 500x500mm, and concurrently leveraging on the beam splitting technique of a high-power fs laser forablation.3. Microsystems cannot be conceived with subcomponents. Mesomorph includes a specific Design-to-LifevaluePlatform to guide the development of new microsystems by fully exploiting the new processes.4. Innovation cannot be limited by the financial risk associated with the necessary investments. Mesomorphimplements a new “Manufacturing as a Service” business model in which all the value chain’s actors can benefit from apositive net cash flow since production's start, effectively removing entry barriers for innovators.Mesomorph consortium is composed of 13 partners from 5 different countries. Each partner represents excellence in its ownfield.

Additive Manufacturing using Metal Pilot Line, (2018-2022) - Responsabile Scientifico

Ricerca UE (non commerciale). Progetti di Ricerca Europei

Abstract

Metal additive manufacturing (AM) allows, by enabling use of advanced design, production of high added value components, at levels that cannot be reached with conventional manufacturing technique. Still, the AM-based manufacturing sequence implies large amounts of critical steps – design for AM, AM fabrication, post processing, etc. – compared to conventional production sequences. Presently, the key competencies related to these steps are either not fully implemented at industrial level (process quality monitoring) or dispersed geographically with poor connection between different steps. Relying on two major AM technologies (LPBF: Laser Powder Bed Fusion and EBM Electron Beam Melting), MANUELA aims at deploying an open-access pilot line facility, covering the whole production sequence, to show full potential of metal AM for industrial AM production.At first, careful instrumentation and adaptation of LPBF & EBM machines will allow increased process reliability and speed. Secondly, the pilot line – including the adapted processes – will be deployed. The hardware layer will integrate novel process quality control monitoring and automated post-AM handling and processing. The line will be fed by design/optimization and AM process simulation workshops. Those workshops will collect continuous feedback from the physical parts of the pilot lines, to increase process reliability and robustness.MANUELA relies on a consortium composed of industrial end user’s, suppliers, (material/powder, AM hardware, quality monitoring system, software, automation and post-AM treatment) as well as top research institutes in powder-bed metal-AM, covering full range of AM technology chain for pilot line deployment.

AMable - AdditiveManufacturABLE, (2017-2021) - Responsabile Scientifico

Ricerca UE (non commerciale). Progetti di Ricerca Europei

Abstract

EU SMEs/mid-caps face clear barriers in the uptake of Additive Manufacturing (AM) related to lack of skilled human resources, and lack of access to know-how, equipment, infrastructure and markets. The principal objective of this project is to overcome those barriers and enable the uptake of AM technologies by SMEs/mid-caps leading to the development of innovative business and service models and new value-chain models in a fully digital environment – thus bringing their ideas and business cases to life and making their innovations Additively Manufacturable (AMable). To achieve this objective, partners with expertise right across the AM value chain have been brought together from the four corners of the EU to:- create an open-sourced-based, living and adapting AM eco-system which can offer required assistance to European SMEs/mid-caps and become self-sustainable after project execution;- provide all necessary assistance to SMEs/mid-caps allowing successful exploitation of AM, including 3 ‘competitive calls’ for experiments;- offer a comprehensive range of (at least 10) AM support services through an open source- and API-based digital marketplace structured as three Platforms (Technology, Business, and Skills and Education);- support and develop ‘best in class’ AM data handling tools and approaches, on an open-source basis.;- coordinate the development of synergies with the already existing I4MS framework, Competence Centres, Digital Innovation Hubs and other related research and innovation activities at the European level.

Sviluppo Tecnologico dell'Additive Manufacturing in Piemonte, (2016-2019) - Responsabile Scientifico

Ricerca Regionale (non commerciale). Progetti di Ricerca su Fondi Strutturali e Nazionali

Abstract

Il progetto STAMP intende sviluppare e consolidare le tecnologie di Additive Manufacturing (AM) all’interno del panorama industriale piemontese. STAMP, attraverso una serie di attività di ricerca dedicate, porterà ad un’evoluzione di tutta la filiera Additive Manufacturing, in particolare per le tecnologie comunemente definite Powder Bed (PB) e Direct Deposition (DD), allo scopo di superare le attuali limitazioni di processo. STAMP, grazie alla sinergia tra centri di ricerca e PMI, sarà in grado di dimostrare l’efficacia econvenienza della produzione Additive Manufacturing per il settore industriale piemontese attraverso due principali filoni di intervento:- La progettazione orientata all’Additive Manufacturing intesa come la somma di tutte quelle tecniche di design e simulazione necessarie per sfruttare appieno tutte le possibilitàdell’approccio AM. STAMP intende eliminare l’approccio empirico (trial&error) al processo attualmente impiegato, definendo le linee guida per la corretta progettazione AdditiveManufacturing. STAMP dimostrerà la validità di tale approccio attraverso la riprogettazione e produzione di casi studio dedicati, selezionati tra i componenti dei settoriautomotive e aeronautico.- Il miglioramento delle tecniche di deposizione AM Powder Bed e Direct Deposition, indagandone i limiti e sviluppando soluzioni tecnologiche avanzate per ridurre gli attuali limiti di processo, incrementando ad esempio tutta la fase di controllo e monitoraggio. STAMP validerà i miglioramenti, in termini di velocità di produzione e controllo di processo, realizzando due dimostratori di macchina di deposizione Additive Manufacturing, una basata sulla tecnologia Powder Bed ed una sulla tecnologia Direct Deposition.
