In an age where turn-key 3D printers are widely available, the idea of constructing a 3D printer from scratch may seem unconventional. However, for those seeking a challenge, the Lemontron offers a distinctive option. This open-source printer is now ready for builders, as the development team has released the necessary files just before Christmas.
Currently, no formal kit exists, but all components can be sourced from various suppliers. A comprehensive bill of materials is available on the Lemontron website, indicating what you’ll need and where to find it. Key parts like the hotend and heated bed can be sourced from KB-3D, while the majority of other components are available on platforms such as AliExpress and DigiKey. Additionally, builders will need a custom PCB from a board manufacturer. Overall, the estimated cost of constructing a Lemontron printer is approximately $400 USD, unless you factor in the value of your time—a commodity likely cherished by DIY enthusiasts.
To get an idea of what assembling the printer entails, there’s an informative video available that provides insights into the assembly process. While it doesn’t serve as a detailed step-by-step guide, it does showcase the design philosophy behind the Lemontron, which emphasizes the use of off-the-shelf parts rather than custom components, allowing the printed parts to seamlessly fit together.
The Lemontron has its roots in the Positron printer, a design that was first highlighted in 2021. Its unique, compact design aims at combining portability with a generous print volume, making it suitable for users who wish to transport their 3D printing project easily.
