What is 3D Printing Software?

3D printing software is the program that allows 3D printers to function. They allow for the reading of 3D model files and the accurate transmission of model data to the printer. More advanced 3D printing software will analyze model designs to ensure print integrity, adjust mechanical parts, map texture and color, allow collaborative workspaces, provide simulation features, inform printing progress in real-time, and troubleshoot issues.

There are two main types of 3D printing software. The first is 3D modeling software, which allows you to use computer-aided design (CAD) to manipulate the sizing, geometry, features, details, and other structural aspects of the object you are printing. The second is slicing software, which “slices” the finished model into separate instructional parts for the 3D printer to make the object layer by layer. 3D modeling software may not be necessary, as there are a plethora of downloadable files for the most common 3D printing objects, but all 3D printers need slicing software in order to transmit printing instructions to the printer. Some 3D printer software combines both modeling and slicing software, and some modeling software allows integrations that perform slicing functions.

3D printing software combines slicing software with elements of 3D modeling and computer-aided design software, which means that you can find a high number of cross-compatible software in this field. Some 3D modeling software have much broader applications, so keep in mind that if the software does not provide a way to slice the model, then it is not a viable 3D printing solution.

3D Printing Software Features

These are the most common features of 3D printing software:

Slicing features and support
Dynamic 3D model manipulation and sculpting
Texture and color mapping
Cloud, web, or desktop-based applications
Generative design
Potential print error identification
Print scaling options
Simulation
Freeform, solid, and mesh modeling
End-to-end collaboration between multiple users and objects
VR modeling support
Ability to read, import, or export multiple 3D model file types
Model and action histories
Network and printer integration

3D Printing Software Comparison

When you are selecting the best 3D printing software for you, consider the following:

Skill level: Your level of comfort with 3D printing will determine which software is best for you. The features, terminologies, techniques, and processes of 3D printing can be overwhelming to beginners. To learn about 3D printing software, it is advised that you learn from Ultimaker Cura, which is free software that combines modeling and slicing in an easy-to-use interface. For more advanced features, such as VR visualization and object hollowing, Autodesk Fusion 360, Materialise MAGICS, and Parametric Creo provides robust suites for both modeling and slicing.

Cloud vs. desktop software: Due to the complex rendering required to show and manipulate 3D models, 3D printing software can be very taxing. If you have concerns that your primary operating machines will not be powerful enough to manipulate models, cloud- or web-based software like OnShape, 3DPrinterOS, and Fusion 360 may be efficient solution to reduce stress on your machines. Fusion 360 and OnShape also allow for collaboration in the cloud, allowing for multiple people to work in the same 3D spaces efficiently. Be aware that you will not be able to control server uptimes with cloud-based services.

Industry: Some 3D printing software has built-in tools and integrations specific to certain industries. While this won’t necessarily limit your ability to use your 3D printer, you may find that the tools or techniques may not synergize with the objects that you make. For example, FreeCAD specializes in architecture modeling, Materialize MAGICS is best used for industrial purposes, and SOLIDWORKS is designed for the creation of machine parts.

Machine type: Depending on whether you are using a filament or SLA 3D printer will determine which files you can use with your printer and your 3D printing software. Generally speaking, STL files are universally read by most 3D printing software, but more specific or advanced modeling or slicing requires different file types that must be compatible with your software in order to print the model. Rhinoceros3D and Ultimaker Cura are the most versatile software options in this regard.

Compatibility with multiple printers: If you need to use multiple 3D printers at once, such as in a classroom, you will need software that connects to all networked printers in the network. You may also need software that allows printers to communicate with each other. Repetier specifically offers this feature, but you may want to speak to vendors directly about their products’ compatibility with multiple printers.

Pricing Information

There are many free, open-source 3D printing software for both modeling and slicing. Professional software can range from $75 to $2390 a year. Some professional software offer free trials, as well as free or discounted plans for students.
