The common attributes of rapid prototyping processes include quick production of prototypes, the ease of iterating and making changes, and being cost-effective. High accuracy and precision are not guaranteed for all rapid prototyping methods.
The common attributes of all rapid prototyping processes are the ability to produce prototypes quickly, the ease of making changes or iterations, and the cost-effectiveness of the method. Although high accuracy and precision are desirable, they are not universal attributes of all rapid prototyping techniques. The essence of rapid prototyping lies in its iterative nature, allowing engineers to refine and improve the design through subsequent prototypes.
This iterative cycle facilitated by rapid prototyping aligns with the spiral design process, ensuring that each prototype is evaluated and tested to bring forth a better understanding of the design's strengths and weaknesses. Cost-effectiveness pertains to minimizing expenses while achieving the goals during the prototyping phase. In summary, options 2, 3, and 4 are common attributes of all rapid prototyping processes.
