3MF File VS STL File : Which 3D Printing File Format Is Better?

In this article, we will understand the differences between 3MF and STL files, two of the most commonly used file formats in the 3D printing industry.

If you work with a 3D printer you must be already aware of these 2 file formats: 3MF and STL. Here we’ll explore the strengths, weaknesses, and unique features of both 3MF and STL files.

Let’s get started!

What is STL File in 3D printing?

STL(Standard Triangle Language) file is a file format widely used for 3D printing and computer-aided manufacturing. In this file format data represents the surface geometry of a 3D object in a series of linked triangles. It doesn’t include any other data like colour, texture, or any other common CAD model attributes. The STL format specifies both ASCII and binary representations, but binary files are more common due to their smaller size.

What is 3MF in 3D printing?

3MF is a new, open-source file format designed specially to simplify the process of 3D printing. In this file format, you can include all the necessary data in a single archive, including color, texture, and other metadata.

This format is designed to be universally accessible, aiming to eliminate the inconsistencies and complexities often encountered with other 3D printing file formats.

Next, let’s see the key difference between 3MF File and STL File comparing both side by side.

3MF Vs STL File in 3D Printing:

3MF File vs STL File with 3D Printed Objects

3MF Files STL Files

File Complexity

3MF files excel in this area, offering a more comprehensive representation 3D models. STL files are limited in their ability to handle complex models with multiple colors and materials.

Information Storage

3MF file format can store more detailed information, including color, material, and more STL file can only contain surface geometry information

Error Handling

They have built-in error detection and correction, leading to smoother printing processes. Files are notorious for their lack of error handling. This can lead to issues when printing.

Universal Compatibility

These are designed to be universally compatible and are increasingly supported by modern 3D printers and software. It have been around for a long time and is widely supported.


3MF files are designed to address the evolving needs of 3D printing technology, making them a more future-proof choice. While STL files have served the 3D printing community well for many years. It continuous to do so.

Date Of Release

3MF files are new and were first announced in 2015. STL was released long back in 1987 when the first stereolithography 3D printer was announced

Full Form

3MF stands for 3D Manufacturing Format. STL stands for Standard Triangle Language or Standard Tessellation Language


In conclusion, STL and 3MF files have unique places in 3D printing. STL, being the older and more widely used format, is often the go-to for many due to its simplicity and compatibility. However, it does have its limitations, particularly in terms of color and texture representation.

3MF vs STL File in 3D Printing

On the other hand, 3MF, a newer and more advanced format, offers a more comprehensive solution, addressing the limitations of STL. It allows for more detailed and accurate models, including color and texture information, making it a promising choice for complex and detailed projects.

However, 3MF adoption is still growing. As we move forward in the ever-evolving world of 3D printing, it will be interesting to see how these two formats continue to develop and shape the industry.
