Project background
Recently, a client with whom we work is working on the development of a new generation of driverless mining trucks. They are facing challenges related to the tight timeline required for testing the prototypes of the key components in the environmental sensing system, as well as the complexity of these components. The design plans for various parts of these driverless mining trucks, such as the multi-sensor integration framework, the lidar housing, and the domain controller casing, have just been finalized. It is necessary to produce two complete prototypes of the sensing system within 15 days in order to test them in the mining area. Traditional machining and molding methods would take more than 40 days, and it is difficult to manufacture complex components in a single step; as a result, there is significant pressure to advance this project.
Given the tight deadline and high technical requirements, the customer turned to its existing suppliers right away, but all of them stated that they were unable to deliver on time. The components of the sensing system for driverless mining trucks are complex in structure and require a high degree of integration; they must meet various criteria such as light weight, high strength, and weather resistance. Traditional manufacturing methods are not capable of meeting these requirements within such a short timeframe, which caused the customer’s project for developing driverless mining trucks to come to a standstill, posing risks of delays in testing phases and setbacks in the overall project progress.
Solution and project outcomes
To overcome these delivery challenges and ensure progress in the customer’s research and development efforts, the customer promptly reached out to the RPS team. Upon receiving the request, RPS quickly established a specialized R&D framework, abandoning traditional manufacturing approaches in favor of industrial-grade 3D printing technology to create the necessary components. The production process was advanced efficiently throughout. The team worked round the clock to optimize printing parameters and adjust material formulas, using high-strength engineering resins to produce components with the precise accuracy and structural strength required. Additionally, special post-treatment processes were applied to ensure that the components could withstand the harsh conditions in mining areas.
Thanks to its advanced material processing techniques and high production efficiency, RPS was able to complete the development and post-processing of two complete prototypes of autonomous mining truck sensing systems within 12 days. A total of 32 core components were delivered, with the dimensional accuracy maintained within ±0.05 mm; these components passed the customer’s tests for structural strength, environmental resistance, and assembly verification right from the first attempt. To minimize the testing time, the team sent technicians to the mining site carrying the necessary components, so as to carry out on-site assembly, debugging, and technical support.
In the end, RPS managed to help the client shorten the development and testing cycle for the sensing system used in driverless mining trucks, thereby saving on costs related to mold production. This enabled the client to proceed with on-site testing in the mining areas as planned. This case clearly demonstrates RPS’s technical expertise and professional capabilities in the field of 3D printing of industrial-grade complex components. Thanks to its efficient and reliable performance, RPS was able to support the development of the client’s driverless intelligent equipment, earning the client’s high praise and interest in establishing a long-term partnership.
