Instead, they might be hollow inside and have walls with a certain thickness. Not all models are supposed to be 3D printed solid. You’ll notice that there are multiple ways of making your object printable in the following video clip.Ĥ: Setting Wall Thickness and Hollowing a 3D Model in Rhino Now, Kyle has created a non-watertight model and shows you which strategies you can use to fix the model and make it watertight. In the first video, we learned how to see if your 3D model is watertight or not. In the following video, Kyle covers some of the other mesh settings, including the ‘Check’ tool, which may be useful as you convert your models to a mesh for printing.ģ: Advanced Mesh Repair: Fixing Non-Watertight 3D Models in Rhino There is more than one way to control the mesh settings. Kyle will talk about how to control the mesh output in Rhino to an STL file and how to set units and tolerances in order to ensure a high-quality 3D print. 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. So let’s prep our Rhino3D model for 3D printing! 1: Checking if your 3D Model is Watertight in Rhino 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.
