3D printing or additive manufacturing is a process modeling for kids lesson 25 making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
It all starts with the creation of a 3D model in your computer. A 3D model is either created from the ground up with 3D modeling software or based on data generated with a 3D scanner. 30 DIY scanners anyone can make at home. 3D Modeling Software 3D modeling software come in many forms.
There’s industrial grade software that costs thousands a year per license, but also free open source software, like Blender, for instance. You can find some beginner video tutorials on our Blender tutorials page. 3D modeling software are often made to suit the functions of the user’s industry. This has resulted in the rise of software suited to specific niches. For this reason, when you are starting out, the amount of choices can be a bit overwhelming, we recommend starting with Tinkercad.
Tinkercad is available for free and it works in browsers that support WebGL, for instance Google Chrome. They offer beginner lessons and has a built in option to get your object printed via various 3D print services. When you have a 3D model, the next step is to prepare it in order to make it 3D printable. Slicing: From 3D Model to 3D Printer You will have to prepare a 3D model before it is ready to be 3D printed.
This is what they call slicing. Slicing is dividing a 3D model into hundreds or thousands of horizontal layers and needs to be done with slicing software. Sometimes a 3D model can be sliced from within a 3D modeling software application. It is also possible that you are forced to use a certain slicing tool for a certain 3D printer. When your 3D model is sliced, you are ready to feed it to your 3D printer. This can be done via USB, SD or Wi-Fi. It really depends on what brand and type 3D Printer you have.
