Qt in Use
Formlabs designs and manufactures pioneering desktop 3D printers, bringing innovative and sophisticated fabrication tools for designers, engineers, and artists around the world.
In 2015 Formlabs introduced ‘Form 2’, the most advanced desktop stereolithographic 3D printer commercially available. Designed for professional CAD users, Form 2 delivers large, high-resolution 3D prints with spectacular details. Its precision and reliability, combined with the intuitive and connected printing experience it offers, position Form 2 in the next wave of 3D printing technology.
For the development of Form 2, Formlabs was looking for a cross platform desktop user interface system capable of ensuring high fidelity user interfaces, including OpenGL integration and easy integration with C++.
The cross-platform nature of Qt was also an influential factor, since many Formlabs’ customers use OS X and Windows.
A user of Qt technology since 2012, Formlabs was able to re-use a significant amount of its existing Qt codebase in the new printer, something that would have been extremely difficult with any other solution, including Android. While Qt Quick enabled developers to create complex touchscreen user interfaces working directly on the product, thus eliminating an often time-consuming dialogue between designer and programmer.

The 3D model processing application, that runs on desktop platforms pre-processing 3D meshes and communicating the information to the printer, made extensive use of Qt libraries for application logic and Qt Quick for the 2D user interface layered on top of an OpenGL view for visualizing 3D data.
With Qt’s testing libraries simplifying the integration of unit tests into Formlabs’ codebase, the company estimates that it saved 30-40 development hours a year in debugging and test case implementation when compared with using non-Qt technology-based devices. The time that Formlabs saved enabled developers to spend more time improving the user’s interaction with the product, including getting the GUI just right.
