Lower cost Rapid Prototyping (RP) kit is enablng a new design strategy of high-frequency testing and redesign.
Rather than wasting time trying to perfect a design and produce a single prototype to show customers, product designers are using rapid prototyping technology to create simple 'first-concept' models of their ideas.
If the customer wants to change something, they can easily go back to churn out a new one without having lost much time or money in the process.
While this cycle of repetitive failure may be both tiring and demoralizing for both the customer and product designers, it certainly now seems necessary to embrace it and very helpful to be successful in either field.
