How To Create A 3D Print File?

Do you want to create a 3D print file but don’t know how? Don’t worry; you’re not alone! This blog post will teach you how to create a 3D print file using some simple steps. First, you will need to find a 3D printer compatible with the type of file you want to create.

Then, you will need to download and install the software required to create your file. Finally, you can begin creating your masterpiece! We wish you the best of luck and hope you enjoy creating beautiful 3D prints.

What Is 3D Printing?

Let’s start with the basics, shall we? To understand how to create a file for a three-dimensional printer, it is important to grasp what exactly three-dimensional printing is.

In short, this type of printing creates objects by depositing thin layers of material on top of each other until the object is complete. The most common material used in three-dimensional printing is plastic, but metal and even human tissue can be printed using this method.

How Does It Work?

Now that you know what three-dimensional printing is, how does it work? The process begins with a computer model or design of the object you want to print. This design is then converted into a format that the printer can read, such as STL or OBJ.

Once the design is in a compatible format, the printer can begin creating your object layer by layer. The material used to create the object is fed into the printer, and the printer creates the object according to the specifications of the design file.

It’s really that simple! Now that you know how three-dimensional printing works let’s move on to how you can create your own file.

What Is An STL File?

The most common type of file used for three-dimensional printing is an STL file. This stands for Standard Tessellation Language and is also sometimes known as stereolithography. It contains a three-dimensional representation of the object you want to print.

An STL file can be created using various software programs, such as Blender, SketchUp file, or AutoCAD. Once you have designed your object using one of these programs, you can then export it as an STL file.

Now that you know what an STL file is let’s go into the details of how to prepare STL files.

Creating Your Own STL

Now that you’re aware of the basic terminologies let’s get started with the process of creating your own STL format. The following steps are involved in the said process:

Select A CAD Program

To build your STL file, you may use various CAD programs; some are better for 3D printing novices than others, while some are better for 3D model engineers and others for 3D model artists.

Consider TinkerCad or Sketchup if you’re a beginner, and Autodesk Inventor, CATIAI, or others if you’re a 3D model engineer. 3D model artists, on the other hand, have the option of using Blender, ZBrush, or Maya. Please choose the program that best meets your needs.

Some sophisticated applications need charges; however, the greatest starter software, such as TinkerCad, Sketchup FreeCAD, and Onshape, is available as free CAD software and is completely free.

Furthermore, because novices do not require a complex user interface, TinkerCad, for example, was created with you in mind because you do not need to install large programming files to get started. Instead, all you need is an account and some knowledge on how to utilize it.

Create Model

Download an appropriate tool to build 3D models for additive manufacturing. Make sure you understand and accept their terms and conditions.

Cookies allow you to enjoy the user interface while also improving functionality. To improve your experience, cookies gather personally-identifying information.

Then set up your workspace and look for simple tools that operate without throwing an error notice. Meshwork editing tools, for example, have no infill and only a shell, making them perfect for editing. After that, use your preferred tool to sketch axes and draw basic 2D models.

Save and Export

TinkerCAD is fantastic since it is designed to make things simple to use. This includes directly storing and exporting STL files to your PC. Unlike some downloadable CAD software, this one saves your work as you make changes, so you never have to worry about losing it.

It should continue to save as long as you have titled your work in the top left corner. You’ll notice a little notification reading ‘All Changes Saved’ to know whether it’s functioning.

As you can see in the image, exporting your CAD files into a downloadable STL file is a piece of cake. Simply select the ‘Export’ button in the upper right of your TinkerCAD page, and a window will open up with a few possibilities.

Choose A Slicer Program

Most 3D model engineers, artists, and enthusiasts are familiar with Cura or have come across it. It’s a widely used cross-platform program for slicing CAD files into STL files for 3D printing.

Cura works effectively and performs the job just as fine as other slicer programs. Therefore, although they’re more slicing applications, we’ll focus on this one because it’s beginner-friendly, and you won’t require much time to comprehend it.

Other slicer applications provide additional capabilities tailored to printers, but they fundamentally do the same thing as Cura.

Slicing Into G-Code Files

In 3D printing, the term “file slicing” is commonly used. It implies that you prepare your CAD file and convert it into a G-code file that your 3D printer can use. The G-code command set controls your printer’s fan speed, movement, and temperature.

You may preview the model as a 3D object after slicing your file before printing. In the edit mode, you can observe every print layer from the bottom, observing how the object’s head travels during printing.

To do so, go through your options and click the slice button in the bottom right corner of your program. Cura software is self-contained, yet getting beautiful prints takes time. As a result, you have the option of customizing parameters to get excellent results.


If you’ve followed the above-mentioned steps, then you will have a printer-ready file of your own models. You can now send it to your printer or take it with you on a micro SD card and enjoy your beautiful prints.

Creating STL files is not a difficult task as it may seem at first. All you need is the right software and some patience to get amazing results.
