3D Modelling of Cave Structures for Structural Analysis

Commendium Ltd specialise in telecommunications and digital solutions and have completed projects for a huge range of organisations, from some of the biggest names in the business to SMEs.

Assistance required

As a part of the company’s ongoing growth strategies it is seeking to establish data collection methods for subterranean cavernous environments. This has led to the company undertaking a series of surveys and collecting point cloud data from some of the world’s largest caves using 3D scanning technology. Lancaster Product Development Unit (LPDU) was approached with the point cloud data to use the expertise of the Engineering Graduate Academy to create 3D models. These models would be used to analyse the caves structure and to create scale models, which would be used to help engineers and enthusiast visualise the caves.

Project outcomes

Scale models of all 4 caves were produced using Selective Laser Sintering (SLS) technology, splitting the models in to multiple parts to allow for study of the internal cavities.

Study of the 3D models confirmed that the Miao chamber in china is now the world record holder for the larges cave chamber at 10.78 Million m3, roughly 10% larger than the previous holder. This was reported in the National Geographic as well as some national papers.

"Commendium approached the LPDU with the aim of devising a simple accurate method of turning very large point cloud models of cave chambers into 3D Models. Key was affordability. The team helped Commendium to select appropriate software and devise an appropriate and cost effective method for measuring volumes and printing 3D models. They also provided independent verification of the veracity of the methods and calculations used. The team are very knowledgeable, capable, are highly articulate and great fun to work with."
