There’s no need to overdo your smoothing and subdividing, in fact it is important to minimize polygons to keep the file size down. Conserve Topologies while Minimizing Polygon Count.In the case of more complex geometries, a “Boolean” operation will join the two volumes and save you the trouble of doing it manually.
The orange area in the example consists of two surfaces which are on top of each other, which will confuse many 3D printing programs, you’ll need to delete the faces and join the two volumes in order to create a printable model. In the example below, the two surfaces form two volumes, however they have a face which overlaps.

Often holes of this nature arise when generating a model for an animation or a video game, as a series of surfaces in one of those situations can cheat physics as per what will and will not be seen – physics can not, however, be cheated during a 3D print. It is also possible to use ‘Ctrl+F’ and “Grid Fill” to close any holes. This is possible by clicking ‘F’ to create an Ngon (or a surface with ‘N’ faces), then extruding, then click ‘Alt+M’ to unify the model. To ensure your model’s printability, it’s important to close any holes in your model. This will cause an issue for many 3D printing programs as they are unable to print models that do not have a defined volume. The 3D model on the left does not consist of a volume, but instead only a series of surfaces which are either a) not closed or b) lacking a defined thickness. To explain the concept of a manifold model, we will use the example pictured below. When modeling for a 3D print, there are a couple rules that you’ll need to follow to ensure that your file will be printable. To keep these Addons activated by default, click on “Save User Settings”.Įssential Tips for Creating a printable 3D Model From there use the search function to find the necessary Addon.Īddons to search for and Activate: “Looptools” and “3D PrintToolbox” To do this, go into User Preferences (Ctrl+Alt+U) and into the “Addons” section. You’ll find the size of the object in the object’s properties (found by typing ‘N’).Ĭertain Addons will be used during this tutorial and it will be important to turn them on. The “Scale” parameter allows you to raise or lower that equivalence globally. By default, one “Blender” unit is equivalent to 1 meter. There you will find measurement options under “Units” - choose “Metric”.
To accomplish this, head to the “Properties” bar and select “Scene” which is represented by a small sphere, cylindar and light. However, as the object you will be designing will be physically manufactured, it’s important to define a unit of scale. All kind of users can also use Blender 3D for basic modeling thanks to its great user interface.Īre you now convinced of the value Blender 3D could bring to your project, either character animation and creation, or 3D printing and willing to learn more about Blender basics? As part of our tutorial series, discover our Blender tutorial for beginners!īy default, Blender uses an inherent system of measurement which is not based on a measurable unit. Character creation is made easier, and visual effects can be added. Game developers especially enjoy its features, both in Edit mode and Object mode, in terms of modeling and texturing, as well as in shading and lighting. This modeling tool is used both by game designers, web developers, engineers, and people wishing to use 3D printing.

You will also find a great number of Youtube Tutorials which can help you get started in the free program and get a good introduction to Blender’s features.īefore getting started, here are a few words about Blender 3D to help you figure out if it’s the right CAD software for you. The basic functionalities of Blender will not be covered in this tutorial.įor more information on the basic functionalities of the program, we invite you to visit the Blender help page. However, it is important to understand some of the basic functionalities of the program as we will be covering the best practices to take your model from the program into a 3D printer.
You don’t need to be an expert in Blender or 3D modeling in order to understand this tutorial. This tutorial is based on version 2.7 of Blender – the most recent version of the software can be downloaded from the Blender website. It covers the essential information for taking your 3D model and turning it into a 3D object using the free CAD software.īlender is a free 3D modeling software which is optimized for 3D animation and rendering using polygonal modeling techniques.
