Next, left-click and drag your sculpt brush over the cube. Click that button and make with the enabling. Expand that panel to see a big button at the top labeled Enable Dyntopo.
Back in the Tool Shelf, scroll down to a panel that's labeled Dyntopo (short for "dynamic topology"). That certainly has its uses, but on a basic cube, it's not particularly interesting. That's because the default behavior for sculpting in Blender is that brushes manipulate the existing vertices in your mesh that are already there. You could try to sculpt on your cube now (left-click and drag your sculpt brush over the cube in the 3D View), but the results are going to be pretty lackluster. That should be the brush that Blender gives you by default. For this example, make sure you're using the SculptDraw brush. On the 3D View's Tool Shelf ( T), the Tools tab gives you the ability to switch between the different types of sculpting brushes that Blender offers and tweak the settings for each one as you work. You should see a red circle around your mouse cursor. With the cube selected, use the mode selection menu in the 3D View's header to switch into Sculpt mode. All of this is because of a technique known as 3D sculpting, and Blender has it built-in.Īs a quick example, take Blender's default scene, the one with the lonely little cube sitting in empty space. That's not so much the case anymore, at least not while creating our models for 3D printing. We used to have to care about the location of each vertex in a mesh and how those vertices connect to form edges and faces (also known as the mesh's topology). In the past 10 years, the process of 3D modeling has evolved from a structural approach to techniques that are far more intuitive. For now, though, let's get into those advanced tools. Despite the power of the advanced tools, a few standard modeling techniques are still necessary to prepare your model for print. Of course, being comfortable with the base set of modeling tools is still valuable.
#BLENDER MODELS FOR CRACK#
However, once you crack the seal on some of Blender's more advanced tools, a whole world of possibilities opens in front of you. Incredible models are created every day by pushing around vertices and using simple operations such as Extrude ( E), Knife ( K), and Loop Cut ( Ctrl + R). Modeling toolsīlender's standard mesh modeling tools in Edit mode are powerful in their own right.
If more precise tooling is necessary after that, you'll at least have a physical object you can reference when building it with CAD. In the context of 3D printing and rapid prototyping, Blender is best suited for quickly getting your ideas in a format that can be printed so you can get a sense of how the "real thing" might look and feel. That said, a lot of consumer-level 3D printers don't have that level of precision, either. Blender simply doesn't have a lot of the precision features that CAD operators expect to see. Rather, its primary purpose is to serve as an artist's tool. Before getting started, I should emphasize that Blender is not a CAD (Computer-Aided Design) tool. In Part 2, I'll examine the process for actually creating those models that you want to print.
#BLENDER MODELS FOR SERIES#
In Part 1 of my series on getting started with 3D printing in Blender, I covered basic preliminary steps for getting your Blender environment set up for creating your own 3D models, ready to be 3D printed.
