Organ Replacement

The challenge for engineer’s orthopedic prosthetic rehabilitation is to find a state of the art in the field, technical or otherwise, that will help their clients who have disabilities. Organ replacement with prostheses is one of the most successful procedures until now. However prostheses are still using standard geometry that has been determined by the manufacturer of the prostheses and it becomes a problem. In addition to the design size that does not fit, long manufacturing process takes time and is expensive also being a problem. Suitability of the prostheses with the patient's body anthropometry and speed of production in the manufacture of the prostheses is very important. In manufacturing, precision and speed of manufacture of the product is something that is possible but requires a high cost, especially in the manufacture of prostheses. By using rapid prototyping technology are available, this research try to develop the customized and rapid manufacturing systems for the manufacture of prostheses, especially for Total Knee Replacement (TKR).

Freeform fabrication and additive fabrication technologies have been combined with subtractive processes to achieve a variety of fully integrated rapid manufacturing systems. The combination of separate fabrication techniques into one rapid manufacturing system results in unit manufacturing process integration, sometimes known as a hybrid system. However, the design methods or approaches required to construct these integrated systems are vaguely described or not mentioned at all. The final product from any integrated system is affected not only by the unit manufacturing processes themselves, but also by the extent the individual units are assimilated into an integrated process. A wide variety of integrated and hybrid manufacturing systems and current manufacturing design methodologies are described in this paper, along with their similarities and differences. Through our extensive review, it was discovered that there are five key elements to a reliable integrated rapid manufacturing system: process planning software, motion system, control system, unit manufacturing process, and a finishing process. By studying the manner in which all other systems have been integrated, a table of successful integrated manufacturing system element combinations has been complied, documenting each of the key element choices, resulting in a variety of modular designs. This paper further discusses the importance of the five elements in manufacturing system integration, and how an integrated system is the way to move forward in the manufacturing domain. To that end, a rapid manufacturing system design methodology was developed that explores designs via process analysis to discover integration potential. Cost-benefit analysis is then used to assess the performance of the new system. This analysis determines if all needs have been met, while staying within the constraints of time and resources. Additionally, a table of common issues and obstacles encountered during manufacturing system development has been compiled to assist in the design and development of future rapid manufacturing systems. To illustrate the design methodology, our modular design experience with a laser aided manufacturing process is presented. Unit manufacturing process integration has increased the productivity and capabilities of our system, which reduced resource volume and increased productivity.

In order to solve the problem of high cost and long cycle in the process of traditional subtractive material manufacturing of a complex-shaped mould, the technology of FDM rapid prototyping is used in combination with the global service idea of cloud manufacturing, where the information of various kinds of heterogeneous-forming process data produced in the process of FDM rapid prototyping is analysed. Meanwhile, the transfer and transformation relation of each forming process data information in the rapid manufacturing process with the digital model as the core is clarified, so that the FDM rapid manufacturing process is integrated into one, thus forming a digital and intelligent manufacturing system for a complex-shaped mould based on the cloud manufacturing big data management. This paper takes the investment casting mould of a spur gear as an example. Through research on the forming mechanism of jet wire, the factors affecting forming quality and efficiency is analysed from three stages: the pretreatment of the 3D model, the rapid prototyping, and the postprocessing of the forming parts. The relationship between the forming parameters and the craft quality is thus established, and the optimization schemes at each stage of this process are put forward through the study on the forming mechanism of jet wire. Through a rapid prototyping test, it is shown that the spur face gear master mould based on this technology can be quickly manufactured with a critical surface accuracy within a range of 0.036 mm–0.181 mm and a surface roughness within the range of 0.007–0.01 μm by only 1/3 the processing cycle of traditional subtractive material manufacturing. It lays a solid foundation for rapid intelligent manufacturing of products with a complex-shaped structure.

In the final Section, we describe our modular design experience to demonstrate how unit manufacturing process integration has increased productivity and the capabilities of a laser aided manufacturing process.
