NURBS is a mathematical model whereas Polygon meshes are a collection of vertices, edges, and faces that define the model.Ĭritical to controlling the quality of your 3D printable model is how the model is meshed. In Rhino, you create an NURBS model, however, 3D printers print Polygon meshes. In this first video clip, Kyle explains why these tools are so essential for creating a 3D printable model.Ģ: Creating a Polygon Mesh with the Right Tolerance in Rhino The best way to find out whether your 3D model is watertight or not is with the ‘ select open poly-surfaces’, ‘select bad objects’, and ‘edge analysis’ tools. For 3D printing, creating a watertight model is a very important step. If you fill up a water balloon with water and tie the top of it and no water comes out, then that’s watertight. Kyle compares a watertight model to a water balloon. Creating a watertight model literally means that no water could flow out of the model if it was being filled up. Sometimes it’s also called a manifold model. Kyle introduces the concept of a watertight model.

He is also the owner of ‘ The Outside’, a digital design consultancy specialized in 3D modeling, photo-realistic rendering, and finding solutions to any design problem. Kyle has years of experience in 3D modeling and will be your instructor in this video series. In this step-by-step video tutorial, he will show you what kind of models are perfect for 3D printing and how you can identify and fix common mistakes. While this might sound complicated, Kyle Houchens, an expert at preparing a Rhino 3D model for 3D printing, will show you how it’s done. When you’re looking to 3D print your Rhino model, some points are very important to keep in mind: it needs to be watertight, exported correctly, and have the right wall thicknesses. Rhinoceros, or short Rhino, is a powerful and versatile modeling software for creating 3D designs.
