Finally, you’ll learn how to use flexible variables, like length, thickness, and width, to design objects. Remember, typing an exclamation mark in front of the cylinder will let you see only the cylinder, and not the cube.Īs soon as you’re able to use the difference operation to cut out holes in your models, you’ll learn how to resize and rotate your objects, and why it’s helpful to “name” a group of primitives. You can create a cube, and then create a separate cylinder, and use the “translate” command to put the cylinder “inside” the cube. Once you’ve learned some of the more basic OpenSCAD commands, you’re ready to create a simple 3D print! You accomplish this by “putting simple primitives into the bigger picture and creating a simple functional 3D printable object.” For example, in his video tutorial, David subtracts the shape of a cylinder to create a plate with a hole in it. To make a flatter cylinder, instead of a taller one, you can specify the radius and height of the primitive separately, but still in the same command, using “cylinder (r = 5, h = 1).” You can also always see the X, Y, and Z axes displayed, down in the lower left-hand corner of the right-hand side of the screen. If you want to make the sphere look cleaner and more, well, sphere-like, you can type the command “$fn=30” to make your sphere out of 30 different parts. So for example, if you type “sphere3” into the editor, you’ll see a sphere, with the dimensions 3 x 3 x 3 mm, pop up on the right-hand side of your screen. The right-hand side shows the result of your typed command as a 3D model. The left-hand side is called the editor, or console, and instead of drawing shapes using your cursor, that’s where you type your commands. When you begin working on a new design in OpenSCAD, the split-screen interface automatically comes up. In order to create a stunning design, you just have to use the right LEGO bricks in the right places.” The tutorial states, “Think about an OpenSCAD 3D model like a LEGO project. You can move the primitives around in a three-dimensional space, and do all sorts of things: rotate them, rescale them, add them together or subtract them (to make cut-outs and holes in your model).

The complex shapes you can create using the software are made up of a large amount of “primitives,” which are simple 3D shapes like cubes and spheres. In his first video for “Part 1 – Introduction to OpenSCAD, Resizing, Moving, Subtracting,” he explains how OpenSCAD actually works, and teaches you about the basic commands. The blog notes that David, with i.materialise, is running the tutorial. Using step-by-step instructions, a cheat sheet, and four helpful videos, you can learn how to use the powerful software, and how to create your first model for 3D printing.

In fact, it recently posted an “OpenSCAD Tutorial & Cheat Sheet: Getting Started with a Free CAD Software” tutorial in the company blog. The versatile program is available for download through Windows, Mac, and Linux.ģD printing service i.materialise is a fan of the software. It is definitely more focused for small parts, and not for organic structures or art projects. OpenSCAD was created in 2009 and allows users to create their own 3D models.
While we all have our favorites, from ImplicitCAD to SketchUp, OpenSCAD is always a popular choice: we’ve written about many objects that were created using this free CAD software, like these Magic: The Gathering tokens. You can’t create successful 3D prints if you’re spending more time trying to decipher the program than you are modeling. If you prefer creating your own 3D models, instead of downloading and printing open-source designs, the most important aspect, when choosing your preferred 3D modeling software, is how easy the process is.
