Major Shift

<p>To solve the tool-making bottleneck, it is fundamental to integrate rapid manufacturing methodologies for rapid tooling, which reduces the lead-time to manufacture the tools while improving their quality. Rapid tooling (RT) is a progression of rapid prototyping (RP). RT is the art of producing tooling directly from CAD models of the part. RT technology plays a major role in increasing the pace of tooling development. This paper describes the role of RT according to the current market situation. An ample review of examples of rapid tooling indicates a new trend of tooling practice. This trend in manufacturing based on rapid prototyping and rapid tooling has already had a dynamic impact on the engineering environment.</p>

Crude Material

Rapid prototyping (RP) advancements are in light of the rule of making three-dimensional geometries straightforwardly from computer aided design (CAD) by stacking two-dimensional profiles on top of one another. Rapid manufacturing (RM) is the utilization of rapid prototyping advancements to make end-utilize or completed items. Aside from the ordinary assembling methods which are utilized for quite a while assembling of an item, added substance assembling methodologies have picked up force in the late years. The explanation for this is that these techniques don't oblige extraordinary tooling and don't evacuate material which is exceptionally advantageous really taking shape of a segment. Rapid manufacturing is the developing innovation in assembling commercial ventures with a specific end goal to create the model inside the less time and expense effective. In this paper we talked about a portion of the fast assembling advancements in light of the sort of crude material is utilized for the procedures, applications, preferences and limits.

Excellent Tool

Based on the annual sales volume, stereolitography (SLA) can be considered a Rapid Prototyping (RP) technology with a promising future. Besides being the pioneering equipment, when RP took the first steps in 1988, this technology has been developed with interesting and fast innovations, and a great activity in patents registration. One can assist to a strong research seeking the enlargement of the system capacity to produce large and micro-size parts, and simultaneously impose the technology as a mass production process that is evolving towards a true Rapid Manufacturing (RM) technology. SLA is an excellent tool to materialize concepts and ideas due to the high-resolution capacity, transparency and fine details of the models and prototypes that can be produced. In this study, the state of art of SLA is analyzed and the recent innovations are presented, and considering that the authors have a considerable experience in supervising design students, from different universities, some of the more emblematic projects that were developed at INEGI – Institute of Mechanical Engineering and Industrial Management, are presented. SLA and direct conversion processes were combined to produce new products in materials such as glass, ceramics and metals, for different industrial sectors.

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).

Innovative Solutions

The pressure of time, quality and cost, together with increasing product variety, more customised products and worldwide competition is driving technology development and implementation in the area of Rapid Manufacturing (RM). Traditionally, the manufacture of tooling for both prototype parts and production components represents one of the longest and most costly phases in the development of most new products. The cost and time implications of the tooling process are particularly problematic for low-volume products aimed at niche markets, or alternatively for rapidly changing high-volume products. Rapid Prototyping (RP) and Rapid Tooling (RT) have the potential to dramatically shorten the time required to produce functional prototypes or products. Functional Analysis (FA) plays a key role in the design process of the actual tools, allowing for innovative solutions that can be achieved with RP and RT. This paper presents a FA methodology to design for manufacture (DFM) based on RP- and RT-specific characteristics, aimed at improving process efficiency, streamline energy consumption, use of volume material, usage of structural innovative lightweight materials, decrease overall costs and improve product quality. Design for Rapid Manufacturing (DFRM) allows for geometric freedom, leading to changes of the overall design process, thus enhancing the FA process. FA begins with stating the need, in a DFRM case that translates into diagnosis, the determination of the manufacturability of the present product and comparison with similar products on the market. Setting objectives, in terms of production costs, quality, flexibility, risk, lead-time, efficiency, and environment are other milestones in FA. Actual function definition involves defining the main functions of the product and their interactions. Clarifying the evaluation parameters, setting criteria levels and technical dimensioning is done for each of the main product functions. The conceptual design process then follows a top-down sequence: corporate, family, structural and component levels. Evaluation and selection of the optimal concept resulting from the FA consists of assessing the manufacturability of the proposed concepts in terms of the DFM objectives. The selected best fit concept is translated to design in the last stage, when the chosen concept is communicated to the development team. The detailed design is carried out in parallel to marketing and product development. Targeted FA is shown to enable generation of innovative solutions, while improving manufacturability. The present research stands as a starting point in the development of product design methodologies that use RP and RT applications for manufacturing physical products.
