This article aims to clarify these differences to help you select the system that best aligns with your needs and preferences.
But before we get started, let’s first understand what open-source and closed-source systems mean in 3D printing.
Open-Source 3D Printer
In the 3D printing open-source system, the hardware designs, software, and firmware are freely available for anyone to use and modify. This openness allows users to customize their printers extensively, contribute to improvements, and benefit from the collective knowledge and innovations of the community.
Closed-Source 3D Printer
On the other hand, closed-source 3D printing systems are proprietary because a particular company retains rights over all designs, software code, and firmware through which they are developed. In most cases, owners of such systems usually have no right to change both hardware and software substantially. The company may update its products for better services but leave limited space for personal alteration thereon.
Some manufacturers of 3D printers, like Bambu Lab, for example, merge open-source and closed-source systems into their products. For instance, while their printers are restricted, their slicer, called Bambu Studio, is an open-source one. Similarly, at the Ultimaker firm, where they issue close-source printers accompanied by an open-source slicer named Ultimaker Cura,
Pros of Open-Source 3D Printer
Transparency
One of the major benefits of using open-source 3D printing systems is that they are transparent.

As there are no licensing fees or subscription costs involved, users end up saving substantial amounts of money, which makes 3D printing more affordable for hobbyists, educators, and small businesses that have limited budgets.
Customization
Open-source systems are highly customizable. Users have the freedom to modify the software and hardware to meet their specific needs. Whether it’s tweaking the software to add new features or adjusting the hardware for better performance, the possibilities are almost endless. This flexibility is particularly appealing to those who enjoy tinkering and want to push the boundaries of what their 3D printer can do.
Security
Open-source systems can also excel in terms of protection. Because anyone can review the code, bugs and vulnerabilities can be quickly identified and fixed by the community. This joint work often results in more secure software that is less likely to break down; there are always many people looking at it and working on it.
Cons of Open-Source 3D Printer
Quality Assurance
Quality has a wide range when it comes to open-source systems. The final outcome depends largely on the creators’ skills and dedication. Some open-source projects are polished and professional, while others may be experimental or unreliable. Users might have to put in extra effort evaluating different options and making sure they choose a good-quality project.
Support and documentation
Although community support may be excellent, there could be a be a lack professional documentation or dedicated support services with open-source systems. Available resources vary in quality, and users may need to rely on community forums or piecemeal documentation, which takes time and can be frustrating sometimes.
Pros of Closed-Source 3D Printer
Professional support and maintenance
Closed-source systems usually come with dedicated support services. This means that users can get help from professionals when troubleshooting or updating their printers’ software. Having access to expert assistance saves time, makes things run smoothly, and makes them more reliable overall.
