CONCR3DE, Dutch pioneer in binder jetting 3D printing, is set to present the power of additive manufacturing in the restoration of historical structures at the AM Summit in Øksnehallen, taking place on the 24th of October.
At the conference, CONCR3DE will be showcasing a groundbreaking 3D-printed reconstruction of a figure from the facade of the Copenhagen Stock Exchange, which was destroyed by an extensive fire in April.
CONCR3DE's journey in renovating cultural heritage began several years ago with the devastating fire at the world-famous Notre Dame Cathedral in Paris. Among the countless artifacts lost in the flames, there was the demon Le Stryge. CONCR3DE used 3D scans to print a replica of the statue, employing upcycled debris of limestone and ash from the fire, showcasing the capabilities of binder-jetting technology for sustainable construction. The work on display at the AM Summit is a further testament of the power of 3D printing in addressing the future challenges of preserving historical buildings.
Matteo Baldassari, co-founder and keynote speaker at the conference, outlines the upcoming challenges facing historical renovation: “Original materials may no longer be available or may be rare, making it difficult to match the original construction. Modern craftsmen may simultaneously have to learn and at the same time use traditional construction techniques that are no longer widespread.” Furthermore, it can be difficult to incorporate modern necessities like plumbing and electrical systems into buildings constructed before the widespread adoption of pull-chain lighting and switches. Craftsmen will be required “not only possess technical skills, but also a deep understanding of history, materials science and modern construction techniques. At the same time, they must have the ability to collaborate effectively with historians, architects, conservators and regulatory authorities.” Matteo adds: “Precise replicas of complex architectural details, such as cornices, stucco and other decorative elements may be too difficult or expensive to make by hand.”
3D printing can help the renovation process since it allows “to recreate intricate structures in a more affordable way without compromising geometric complexity and sustainability.” “Custom components that match the original design can be produced quickly and accurately.” To safeguard historic buildings against potential damage, Matteo Baldassari recommends 3D scanning. Digital models can then be printed to replicate lost or damaged elements, ensuring the preservation of the original design. These scans can also be archived for future restoration projects or educational use.
Matteo Baldassari talks about his work on the Main Stage at AM Summit 2024 from 2 p.m.
