Advantages & Disadvantages of Rapid Prototyping

Satisfactory Essays
• Speed
The time spent using rapid prototyping techniques has decreased by as much as 90% compared to other prototype methods. Creating the tooling for injection molding and other conventional prototyping processes can take days. With rapid prototyping, the same model parts can be made within hours.

• Time to Market
The faster a prototype is created, the quicker designers and engineers can analyze it for design flaws and make necessary adjustments. The next step after making these adjustments is manufacturing. A 60 to 90 percent reduction in prototype creation has a direct impact on how quickly companies can release their products to market.

• Cost Savings/Reduction
Creating the tooling for injection molding prototypes is not only laborious, but expensive. In addition, tooling can only be used for creating that particular part. Rapid prototyping systems build parts in an additive, layer-by-layer manner. These systems can be used over and over again to build a variety of different parts within their build size.

• Disadvantages of Rapid Prototyping
Some sources are of the opinion that rapid prototyping is not effective because, in actual, it fails in replication of the real product or system. It could so happen that some important developmental steps could be omitted to get a quick and cheap working model. This can be one of the greatest disadvantages of rapid prototyping. Another disadvantage of rapid prototyping is one in which many problems are overlooked resulting in endless rectifications and revisions. One more disadvantage of rapid prototyping is that it may not be suitable for large sized

    Rapid Prototyping can be defined as a group of techniques used to quickly fabricate a scale model of a part or assembly using three-dimensional computer aided design (CAD) data. What is commonly considered to be the first RP technique, Stereolithography, was developed by 3D Systems of Valencia. Rapid Prototyping has also been referred to as solid free-form manufacturing, computer automated manufacturing, and layered manufacturing. RP models can be used for testing, such as when an airfoil shape…
