A Streamlined Decentralised Workflow for Obtaining Specific Mechanical Performance and Grade of 3DPC (2025-10)¶

This work presents findings of ongoing experimental research on 3D Concrete Printing, aiming at rationalising the production parameters in favour of the final mechanical performance – the grade – and at the same time proposing a decentralised approach for the rapid definition of production standards and their reliable and tamper-proof distribution to streamline the obtaining of a specific 3D-Printed Concrete grade. Moving from preliminary considerations about the fragmentation of current research, we suggest approaching the standardisation problem from the basic principle of the structural requirements rather than the development of hyper-specialised materials. We propose a 2-step experiment with the creation of a Distributed Ledger Technology-based decentralised framework acting as a repository of experimental data from different production laboratories, each with its specific setup and production settings. In the first stage, the decentralised framework collects and analyses the production data, detecting different production settings and mechanical performance relations and patterns. In the second stage, the system suggests optimised production settings for obtaining the required grade. The decentralised framework constitutes the infrastructure for the definition of production standards based not only on construction requirements but also considering the variable production setups, laying the foundation for a smoother adoption of the standards.
