RP = Rapid Prototyping. We all know that – RP technologies are traditionally used to create rough “test” objects, suitable only for eyeball inspection. This is due to current limitations in materials that result in solid, but not so robust printed objects. Don’t sit on that model! “Yes, it looks good, now send it off to the real manufacturing process.” There’s exceptions to this, where the function of the object doesn’t actually require robustness, such as artwork.
But now that’s starting to change. Consider Objet’s case study on using 3D printed parts for RC model racing. Certainly, it’s not Formula 1 racing, but these small vehicles involve plenty of moving parts that must perform perfectly if the race is to be won. Nimrod Racing uses their Eden 250 3D printer to produce many tiny parts for these vehicles that are not only much lighter than their metal ancestors, but they are also sufficiently robust to withstand the rigors of high-speed RC racing.
