3D printing technology is becoming increasingly popular. Mainly because users can now easily use a 3D printer to execute the additive manufacturing process of a 3D modeling software. Here’s the catch, STL files (Standard Tessellation Language) are also integral to printing these designs because they provide the necessary instructions for successful 3D printing.
This beginner’s guide is here to show you the ropes. You’ll learn about the essential 3D printing tools/software and useful information on 3D printing standard file type –the STL file. Not only that, but you’ll also understand how to use these tools to export functions and create print-ready files in this format.
Investing time in creating suitable STL files ensures that 3D printing produces the best results. With the software and practices recommended here, your workflow in creating STL files for quality prints is assured in the 3D printing industry.
How to Create an STL File
Creating an STL file means designing a 3D model within CAD software and then creating the STL file (the language the 3D printer can understand) with a slicer software. Note that; the types of designs you can create vary, so it is essential to consider the physical limitations of your printer and the material you have chosen.
Also, you will need to start designing your Model in a digital form before you can create the STL file.
•You can design a CAD file and then use slicer software such as Blender to create the STL file.
•Or, you can download an already designed 3D model and then translate it into the STL file with the slicer program.
The above information is the surface knowledge required for everyone interested in 3D printing. Below, we will explain how to create an STL file from the start to ready in a do-as-we-do style. The steps include:
Start With 2D Design
Generating graphic layouts and digital content is known as graphic design (2D design). It involves illustrating your object idea onto a flat plane or surface without considering the depth or volume. Additionally, 2D designs may be divided primarily into these two groups:
- Vector-based graphic design: It uses geometric shapes, lines, and curves. This type of design allows for greater flexibility regarding size adjustments and other modifications.
- Pixel-based graphic design: It is made of pixels, which are tiny squares of color. This type of design is best for creating complex pictures, such as photographs and detailed graphics.
Create the 3D Model
Once your design has been illustrated, it is time to create the printable 3D model file, and you can do this in a CAD model program like Fusion 360 or Autodesk Inventor.
Creating a 3D model involves manipulating and combining simple shapes into more complex structures while considering the Model’s depth. You may also need to adjust the Model’s size, orientation, and other parameters.
Transitioning to 3D Design
As a beginner, sketching your idea in 2D and then transferring the illustrated 2D design into a 3D is best. So it may be challenging to shift your mindset from seeing your artwork on a 2D flat sheet of paper to a 3D one.
During this situation, remember that sometimes the 3D form of your creative project only takes shape once you’re ready to display it, even if you did the entire process and labor in 2D. So don’t be worried too much about your first 3D designing process; you will surely get it next time. After all, the human brain can think in 2D and 3D.
Extrusion of 2D shapes
Extruding is the simplest method for converting a 2D form into a 3D object because it forces the two-dimensional geometry into the third dimension by adding a Z-axis depth.
An extrusion produces a 3D shape with width, height, and, recently, depth. Extrusions are excellent for making block-like objects, columns, panels, and the like, but the resultant sharp edges unmistakably have a CG eel.
It is also a good technique in 3D modeling, and it is commonly used for creating basic shapes and adding volume to 2D designs.
When you want to extrude a 2D shape, you must first define it using polylines or splines and avoid holes in the item by ensuring the lines are clean and neat. Once you are sure the 2D illustrated shape is okay, use the CAD software to extrude it.
Exporting into STL File Format
Once your 3D design is complete and in a 3D file, you must export it into an STL format to validate, refine & share your design on 3D Printing platforms and enable printing via the 3D printer.
It also allows the Model to be read by the 3D printer. You can do that by following these steps:
- Open the single file in your 3D printing software tool of choice and then select Export from the main file menu (file > export).
- It will bring up a list of supported formats.
- Select STL to save it as an STL file.
- You’ll also be asked to specify print quality settings- select the most appropriate option for your needs and then click Export.
That’s all there is to it! Store your exported STL files in an appropriate folder on your system for easy access later.
Materials Qualities
The material quality of the STL file will depend on the level of detail in your 3D model illustration. The more detailed the Model is, the higher the resolution of the final print.
However, if your design has too much detail, it may be difficult or impossible to construct a quality 3D print due to its complexity.
Rules and Regulations
It is important to remember that some 3D printer menus have rules and regulations about what types of files they accept.
For example, STL files must be within a certain size range or adhere to specific material requirements. Be sure to check with the service provider for their guidelines before you submit your STL file.
STL Files for Products Designer
STL files are widely used CAD software for product designers around the world. Their versatile and comprehensive range of applications offers a wide array of advantages.
From 3D CAD models to renderings, STL files make it simple to design any product imaginable. You can also use these CADs in various ways, such as an online quoting tool or even in producing an end-use product to enhance continuous improvement.
Most CAD software programs allow users to quickly create complex models using CAD libraries and pre-made parts lists. It speeds up the workflow tremendously and streamlines the design process with minimal effort on behalf of the designer.
Ultimately, STL files offer unparalleled versatility and convenience for product designers everywhere.
What Are STL Files Used For?
STL is a 3D object-file format used by 3D printers and 3D modeling programs. STL uses include:
Rapid Prototyping
The most popular and widely accepted use for STL files is rapid prototyping or pre-production of three-dimensional physical parts with CNC machining and 3D printing.
Reverse Engineering
STL files are often used in reverse engineering applications, such as scanning physical objects and creating virtual-3D models with CAD/CAM software.
Data Sharing and Storage
The STL file format is a great way to store 3D model information for a smooth 3D printing process. In addition, STL files provide a convenient way to share data between multiple CAD platforms, and you can export them from almost any 3D modeling program without losing any of their information.
Robots Representation
They are often used in robotics to accurately represent robots’ body parts before building them. With these useful features, it’s no surprise that STL files are increasingly gaining popularity among engineers and industrial designers for a smooth surface finish.
Pros of STL Files for 3D Printing

- STL file is an effective way to store 3D models for computer-aided design (CAD) systems, making it ideal for Hardware and Function Design.
- STL files are easy to produce from digital models and can quickly be taken from the computer screen to a physical object via a 3D Printer.
- Agencies benefit from STL’s relatively simple structure –allowing them to modify the level of detail when applications necessitate smaller screens or faster printing times during prototyping stages.
- STL files give agencies tremendous flexibility in digital model-to-real-world printing compared to standard formats.
Cons of STL Files for 3D Printing
- 3D printing with STL files can be confusing due to their complexity.
- If the file is not formatted correctly, the 3d slicer program won’t be able to read it accurately and will produce an invalid shape, thus requiring STL repair to correct errors.
- STL files often contain a high polygon count where it doesn’t need to be, making them difficult for machines to translate accurately into physical objects.
- To create successful 3D printing stories, we must also consider standard vector orientations. It can be difficult if sharp points or unbonded basic shapes cause slicing irregularities or interference in how layers stack up when printed.
