An example is its design of the Buga Wood
Pavilion, a 500m² experimental timber shell structure that served as an open event space with a multi-purpose stage at the Bundesgartenschau 2019 in Heilbronn. It features 30m spans.
The structure features 376 load adapted
hollow structural elements and 17,000 finger-joints, made possible by robotic manufacturing to a tolerance of 0.35mm. This enabled the elimination of scaffolding and formwork in site erection. The design-to-build process took just 13 months and the structure was able to be later disassembled and moved to another location.
Such detail would have been impossible without the use of computer design and latest woodworking technology. Prof Menges said a next step would be to use robotic site assembly. Further research examined 350 existing timber buildings and found about 99% of them were based on regular and very rigid traditional grids – which Prof Menges argues is a limiting factor. As a result the research teams developed a prototype multi- storey timber building system, fabricated in a prefabricated element test factory using robots. They were able to design an adaptive building system with variable column placement and 11m-long clear spanning timber floor slabs 42cm in depth. Such features, he added, were a positive disruptive influence in the construction industry.
Some of the big machinery names sharing
their Ligna plans at the preview included Fagus-GreCon, Kleiberit, Cefla, Homag, Hymmen, Biesse and SCM.
Of course, a full range of technology
companies serving the wood-based panels industry, both in primary board production and downstream technology will be present at the exhibition, mainly in Hall 26 – many of them are included in our Ligna preview entries following this feature. This includes the main plant suppliers Dieffenbacher, Siempelkamp and IMAL PAL Group.
Digitalisation is an increasing feature inside wood-based panel plants and Ligna will be a showcase in this respect. A full review of all innovations at Ligna will be included in WBPI’s Ligna review in the next edition.
But here are a few teasers from some of those at the preview and main plant suppliers.
Dieffenbacher, which will celebrate its 150th anniversary at Ligna, will talk to visitors about the new smart plant concept CEBRO, which combines the new digital platform EVORIS and advanced plant engineering with operational excellence and sustainability solutions. EVORIS is designed to enable wood- based panel manufacturers to digitalise their production. With the help of artificial intelligence (AI), EVORIS apps support continuous monitoring, prediction and optimisation of production processes. Ligna attendees will learn all about this in the presentation “How artificial intelligence is transforming the wood-based panels industry” on “
LIGNA.Stage” on Monday, May 15 at 11:20 in Hall 12. Stefan Zipf, head of the wood business unit at Dieffenbacher, said the company was looking forward to a “very special Ligna 2023”.

specialist Fagus-GreCon told WBPI that it will present many innovations at Ligna. The company said the exhibition’s focus on current industry topics such as digital transformation, increasing efficiency demands and the resource-conserving use of wood as a raw material, showed why Ligna is probably the most important trend barometer for the entire wood-based materials industry. “We have a lot of new products on offer and are looking forward to presenting them to the trade public,” said Uwe Kahmann, managing director of Fagus-GreCon. “Extensive investments have been made in product developments and our services. This is now paying off for our customers.” Its measurement technology highlights include further development of the inline thickness measurement GreCon THICKNESSCONTROL, which enables measurements of almost the entire panel, even at high production speeds. The GreCon GASANALYSER MC determines the formaldehyde emission of wood-based materials, with considerably shortened testing times, improved operability and noticeably extended calibration intervals. In fire prevention, Fagus-GreCon has
continued the digitalisation of its product portfolio. Following the intelligent detection technology (IDT) at the last Ligna, it now presents a maintenance-optimised extinguishing system with intelligent extinguishment technology (IET). Leading Italian plant supplier IMAL PAL Group will showcase its high pressure resination system for PB, MDF and OSB lines, installed to reduce resin addition by between 10% and 20%. Moreover, the Dynasteam, a system which injects dry steam into the mat prior to pressing, will also be centre stage.
