Additive or subtractive? Which rapid prototyping process is right for your job? Author: Jim Destefani Manufacturing Engineering, April 2005. As the mix of work has shifted away from form and fit applications towards a preponderance of functional prototypes, it's become more difficult to select a process. The Addition of Subtraction. Author: Will Curtis. Time Compression Technologies, Nov., 2003. Low-cost milling machines are presented as a solution to the rapid prototyping problem. The author is with Roland DGA. Is CNC Machining Really Better than RP? Authors: Terry Wohlers and Todd Grimm. Time Compression Technologies, Jan., 2003. Better isn't the point; it's really a question of knowing which technology is appropriate for a particular application. VP and Testing Accelerates Production Time for Hand-held Knife. Author: Jenna Plank Time Compression Technologies, Nov., 2002. This is a case study of the use of virtual prototyping and CAD to replace previously used handcrafting techniques. John Henry Outperforms Collaborative Technology. Author: David Dobrin. CIO. Oct. 1, 2002: RP and other digital technologies sometimes look better on paper than in practice. A case study showing how old-fashioned hand work succeeds in at least one case in the rapid-turnaround sneaker business. Virtual Product Development Using VP and VR. Author: John Connolly. Time Compression Technologies, May, 2002. Two trends being seen in virtual product development: 1. Virtual reality (VR), with an emphasis on visualization and simple functionality demonstration. 2. VP, with a strong focus on testing product performance, strength, durability and other engineering parameters. In VP, the focus is clearly on simulating the physical parameters of the product being designed.
