Ultimately, a 3D CAD model is always an approximation of reality; it incorporates the information that you have thought about, as well as the things you haven’t (yet) considered.
During the Fair Design reception at MadeIn4Havens, our very own Antony Weinbeck gave a presentation about how we at Spark cleverly combine Computer Aided Manufacturing with prototyping, including with 3D printers. Antony: “A prototype makes our blind spots patently clear. You can learn a huge amount from this. And the earlier you take the step ‘from bits to atoms’, the better your design will be in the end. What’s more, you’ll also save a lot of costs, because the earlier in the process that you make adjustments, the less chance there is of causing a big chain reaction later.”
