Cura File Formats: 10 Best Options
Cura users might often get confused about which 3D file formats to use for designing. Nowadays, the availability of numerous 3D file formats makes it hard to choose the best. But these available file formats may not cope with Cura’s demands. Choosing the suitable file format is necessary because opting for the wrong one can lead to loss of your stored data, troubles in file transfer, failure of projects, and many more. In professionalism, all these obstacles can dwindle your scope in the market.
In this article, we will share the top ten 3D file formats for Cura with you. So if you are a Cura user or are thinking about using it, this article will benefit you. Let’s get going!
10 Best File Formats for Cura
- 3DS
- STL
- OBJ
- AMF
- STEP
- COLLADA
- PLY
- FBX
- 3MF

When it comes to different designs and drawings, 3DS max is the top preference of customers. 3DS is one of the foremost 3D file formats designed and used by the famous Autodesk 3DS software. For many years 3DS has been universally accepted by all 3D software. 3DS serves in almost all 3D software and is well established for transferring information between 3D programs; that's why this versatile file format is best suitable for Cura. 3DS offers the most necessary information about mesh, objects, camera location, lighting, color, material, toughness, etc.
3DS file format covers the most basic information about geometry, appearance, scene, and animation. It has become standard to retain 3D models within a few years and generally uses triangular mesh to encrypt the surface geometry. Also, this file format does not support directional light sources.
Pros:
- Best suitable for architect modeling.
- Provided with different shades.
- Cope with every 3D software.
Cons:
- It does not support directional lightning.
- Takes less time in rendering.
2) STL

STL is another exemplary 3D file format for Cura. In 3D printing, rapid prototyping, and computer-aided manufacturing, STL is implemented mainly by different reputed 3D printing software. In 1987 Chuck Hull conceived this neutral 3D file format. Initially, it was only created for transferring information between a prepared CAD model and a 3D printer. It has an extension .stl.
The STL can be harmonious with almost 3D software, including Cura. This file format changes your prepared design into a series of triangular surfaces to make its shape. You can easily create an STL file for your original model via export. When you change your file into STL format, it can be shown as a format.TXT of word processing in which only basic information related to design and shapes are included.
Pros:
- STL saves the geometry of models.
- Compatible with Cura.
- STL files are simple and easy to use.
Cons:
- STL does not encode color information.
- Usually, STL is replaced with different modern file formats.
3) OBJ
OBJ is a neutral 3D file format in the domain of 3D printing. Cura also plays with this 3D file format. Actually, OBJ is widely used in computer graphics and non-animated 3D models. Created by Wavefront technologies, this file format has the extension, i.e., .obj. Unlike STL, OBJ can encode the surface geometry and save the model color and texturing information.
The OBJ file format can support approximate and precise encoding. Moreover, it does not obstruct the surface mesh to the triangular facets. Other polygons can be used; for example, quadrilaterals can be employed according to consumer compatibility and usage. Encoded color and texture information can be easily stored in separate files with the extension, i.e., .mtl (Material Template Library). Moreover, the OBJ file format is considered one of the most popular formats for Cura and other 3D graphics and color printing.
Pros:
- Uncomplicated and neutral file formats.
- Encode the surface geometry with great versatility.
- No need to store color and texture information.
Cons:
- Not space-efficient.
4) AMF
AMF, also known as additive manufacturing file format, basically stores and describes objects that would be processed through additive manufacturing. It was introduced to replace STL file format because of its different pitfalls. Initially, it was introduced as an ASTM standard file format. It is an XML-based file format that supports additional file specifications such as geometry, scale, color, orientations, etc.
Comparatively, AMF is much more efficient than STL file format. There is no need to think about storage, color, and texturing information.
Pros:
- AMF file format can be supported by Cura.
- Comparatively large storage than other file formats.
- Bloating of files is low in the AMF.
Cons:
- Not acknowledged by users.
5) STEP
STEP is one of the most precise file formats employed by Cura users and can be a good option when detailed 3D printing is required. STEP can also be defined in terms of accuracy and compatibility. The STEP file format can read and store the entire 3D model compared to the STL file format. Along with detailed and precise file storage, STEP files are exact and compatible compared to STL file format.
Pros:
- One of the best compatible and precise file formats.
- Maintain a high dimensional accuracy.
- The STEP file format saves the file as a single entity.
Cons:
- STEP is less popular than STL.
6) COLLADA
COLLADA is also one of the neutral file formats mostly used in video games and film industries designed and developed by non-profit technology - the Khronos group. The file extension for the COLLADA format is .dae.(digital asset exchange). COLLADA introduces itself as a barrier wall breaker between different 3D additive manufacturing software.
COLLADA is harmonious with various 3D software, especially with Cura, to share, open and edit files. COLLADA offers you to store different ranges of contents, including 3D images, colors, textures, and 3D models. COLLADA files are not limited to particular programs and manufacturers; that's why they are most compatible with Cura.
Pros:
- COLLADA files are not limited to selected geometry files.
- It is compatible with multiple additive manufacturing software.
- It supports physical simulations and animations.
Cons:
- COLLADA can be a slow process.
7) PLY
“Polygon File Format” or PLA, also known as the “Stanford Triangle Format,” was initially created to store the data from 3D scanners, whereas PLY is widely used in the dental sector. Projects file archives contain .pla. The ArchiCAD modeling application created the file extension. These files can easily store various CAD designs and library information such as color and texture details.
Many software, mostly gaming software such as NHL video games, uses .pla file extension.
Pros:
- PLY is well known and widely used in the additive manufacturing industry.
- It can be a suitable replacement for the STL file format.
Cons:
- PLY does not perform reasonably on all resolutions.
8) FBX
FBX is a 3D file format offered by Autodesk where you can save your 3D model in the Autodesk film box format. FBX provides its service not only on Autodesk but also on varieties of digital modeling and many additive manufacturing platforms, including Cura and many more. These file formats are often used in creating video games and animation.
Pros:
- FBX supports extensive features.
- It is swift and efficient compared to other file formats.
- Perfect compatibility with other 3D software.
Cons:
- One of the most important disadvantages of employing FBX is its closed format.
9) 3MF
3MF was specially designed to keep in view of the advancement in 3D software. As 3D printing has seen significant growth in recent years, creators are constantly looking forward to the best alternative for STL. So various additive manufacturing platforms have devised this versatile file format program in 3MF.
It provides a high-quality 3D printing experience for consumers as well as manufacturers.
Pros:
- Considered as one of the best suitable file formats for Cura.
- Speedy and easy to use with excellent efficiency.
Cons:
- Lack of color and material information.
10) IGES
IGES uses .iges file format and is an appropriate alternative file format option for Cura. It is a versatile file format that transfers two or three-dimensional data between CAD software and a 3D printer.
This file format contains information related to the model surface and stores color, geometry, and circuit information.
Pros:
- Easy to use file format.
Cons:
- File translation can lead to a mismatch in the geometry of models.
