There are companies that are set up to carry out 3D scans of virtually everything so no need to buy them. Some enterprising companies are offering all kinds of 3D printed products. A quick Google gives an example:
Perhaps this is something that we should seriously discuss with LOCI?
Currently there are a variety of "cheap" home 3D printers that can make small items primarily from a range of thermoplastics. However, there are also many examples of complex items being made for the automobile, aeronautical, medical and other sectors using a wide range of materials including metals. In China they are even printing houses!
The future for the classic car market to manufacture spare parts is already underway. Not for Landcrabs of course, but for the more exotic and valuable vehicles. The process involves taking laser scans of the original parts and using the software to drive CNC type 3D printing machines.
At present the cost of manufacture is probably prohibitive for our types of vehicle but the cost of scanning is falling quite rapidly. What may be feasible would be to arrange scans of Landcrab components as they are becoming scarce so that they could be manufactured in the future when costs fall as anticipated as the technology improves and competition increases. In theory there is nothing that could not be made by 3D printing - even hydrolastic units maybe.
