Sister Projects

i4Q is part of the 4ZDM cluster, the European initiative around the Factories of the Future Zero Defect Manufacturing priority which aims to promote the adoption of zero-defect production and quality control systems by industry.


i4Q’s sister projects funded under DT-FoF-11-2020/DT-FoF-10-2020 are InterQ, DAT4.ZERO, OPTIMAI and PeneloPe. A Common website gathering all projects is available here.


The PeneloPe Project

Closed-loop digital pipeline for a flexible and modular manufacturing of large components.

PENELOPE aims to develop a novel closed-loop digital pipeline. An end-to-end Digital Manufacturing solution, enabling a bidirectional dataflow for seamless integration across the entire manufacturing value chain.

The OPTIMAI project

The OPTIMAI project aims to create a new European industry ecosystem focused on innovative solutions to optimise production, reduce defects and improve quality to safeguard European industry for generations to come.


The OPTIMAI toolkit will be tested and validated in three selected pilot sites that cover a number of industrial domains: manufacturing of lifts (KLEEMANN, Greece), manufacturing of antennas (Televés, Spain) and assembly of microelectronics (Microchip Technology Caldicot Ltd, UK).


The InterQ project


The InterQ project aims to measure, predict, control and manage the quality of the manufactured products, manufacturing processes and gathered data to assure Zero-Defect-Manufacturing through all the value chain.


It proposes a new generation of digital solutions based on intelligent systems, hybrid digital twins and AI-driven optimization tools, powered with meaningful and reliable data, to assure the quality in smart factories in a holistic manner.

The DAT4.ZERO project

DAT4.ᴢᴇʀᴏ is a project supported by the European Union. The project has 20 European partners who will work to improve quality in European factories.


Innovative technologies will gather and analyse data from manufacturing processes and give businesses greater control of what happens during production.


Additional related Zero Defect Manufacturing projects



Zero Defects Manufacturing Platform (ZDMP) – is a multi-partner project that aims at providing an open platform to support factories to reach a zero defects goal. In this context, ZDMP will allow end-users to interconnect their systems (e.g. shop floor and ERP Systems) through ZDMP Applications (zApps), to improve product and process quality assurance.



openZDM, a project funded by the European Union’s Horizon Europe research and innovation programme, aims to provide an open platform to support production networks’ zero-defect processes, bringing together existing R&D solutions and creating an innovative state-of-the-art integrated solution.

Through five industrial pilots in real-life operational conditions the initiative will test and finalize the technological tools and facilitate the adoption of the openZDM solution: a digital platform that builds on the state-of-the-art Reference Architecture Model for Industry 4.0 and Asset Administration Shell, non-destructive inspection (NDI) methods and data-driven quality assessment techniques for online defect identification and quality assessment. Furthermore, a Digital Twin, key enabling technology for online process adaptation and waste reduction.



ENGINE is a project funded by the European Union’s Horizon Europe research and innovation programme that aims to reduce the environmental impact of the manufacturing process and improve the competitiveness of metal product manufacturers by developing a novel metal product design and manufacturing system. The ENGINE system combines three integrated modules to facilitate industrial data-management, computational product and process design with in-situ diagnostics, production monitoring and control. It integrates Life Cycle Assignments in design and business decisions, reduces defects, waste, and shrinks product time-to-market.



FLASH-COMP is a new Horizon Europe project that started in October 2022. The aim of the project is to bring novel digital technologies to the liquid resin infusion process (LRI), one of the most widely used manufacturing processes using composite materials. By bringing advanced automated controls and in-line defect monitoring and detection to the LRI process, FLASH-COMP will allow industry to cut material waste significantly, while also improving efficiencies in the process and the quality of products produced.



Wind turbines are already part of everyday European life and are an essential element of the strategy to meet the Green Deal targets. Wind turbine blade (WTB) size is steadily increasing with the largest new offshore blades >100 m in length. Composite blades are manufactured using resin infusion and coating processes. Even using modern manufacturing methods, these are subject to defects which result in re-work, scrap and repair.

TURBO will reduce defect formation through better process simulation, monitoring and control, improve defect identification with new methods of non-destructive testing (NDT) and introduce novel repair strategies in composites and coatings.



ZDZW develops digital non-destructive inspection (NDI) services as a set of strategic technologies to improve production efficiency, zero-defect, and sustainable manufacturing of European industries. Several TURBO partners (UPV, DTU, NORBLIS) are also involved in ZDZW so there is a strong overlap between the projects, and the objective of reducing defects in EU manufacturing.
