Conclusion: Now you test the design, whether through FEA modeling, modeling the assembly components for the overall mechanism, or a prototype print.This involves sketching rough ideas on paper and brainstorming with colleagues to create a draft version of your 3D model. Experiment: Utilize all information gathered in steps 1-3 to start modeling.Factors to consider here are form, fit, and function to create an aesthetically pleasing and functional design. Once I have a clear understanding of the project’s requirements, I start conceptualizing the design. Now’s a good time to make some hand sketches and share the preliminary design concepts with team members to get initial feedback. Answer your problem questions to finalize the design conceptualization, involving any hand calculations for things like minimum material thickness needed to withstand loading. Hypothesize: Make a hypothesis or an educated guess as to which design works best.What do we hope to solve? I put the answers into a desired or outcome column. Question: Ask why this problem needs to be solved.Unknowns may be design features, tolerances, and material selection. The knowns may be functional specifications, performance criteria, and any constraints such as size, weight, or cost. I write down knowns and unknowns in separate columns. Observation: Gather all the relevant information about the problem your design is trying to solve.Simply put, when designing something new I use the following steps, modified from the method above: There are a lot of problem-solving techniques out there to figure out the best design for your specific application - personally, I prefer a variation of the scientific method: Preparation is key to ensuring any process works and this holds true for designing 3D models as well. Preliminary Information Gathering and Rough Design Ideas Pro-Tip: Check out the Fictiv Capabilities Guide to see how Fictiv can help make your 3D models a reality. So, we wanted to share our best tips to start designing 3D models for printing - that apply to any of the vast number of 3D modeling programs available for creating simple and complex 3D-printed models. The first steps to designing 3D models, while exciting, can be overwhelming, too. Whether it’s a complex CNC part, a simple mechanical assembly, an innovative new product development (NPD) design, or a 3D printed mechanism, every project presents unique challenges and opportunities for innovation. When you’re a mechanical engineer like me, starting a new 3D model design is equally exciting and nerve-wracking as your mind fills with possibilities.
