Wube Software and Prusa Research collaborate on physical Factorio models

Origin of the Project

The idea for physical Factorio models emerged during a playtesting event for the Space Age DLC in the summer of 2024. Wube Software organized the event to gather in-person feedback, and Prusa Research joined to provide accompanying programs. During this event, a simple model of a Wriggler was 3D printed, sparking interest in creating more physical representations of game elements.

Development and Design

Following the DLC's release and subsequent updates, Wube Software began prototyping physical models in their spare time. The team decided to focus on transport belts as a core concept, leading to the development of a grid system for placing entities. Jarosław designed the initial concepts, including inserters, with numerous prototypes printed to refine the designs.

The development process identified a need for two distinct versions of almost every model: one with high precision for push-fit assembly and another with high clearance for easier printing and gluing. This approach accommodates different user preferences and printer capabilities.

Expanding the Model Set

As Jarosław continued creating player-built entities, Fearghall developed models for enemies, starting with the biter spawner. Subsequent additions included chests, the player character, and a stone furnace. The project focused on early-game entities, resulting in 15 model sets containing 65 individual pieces to manage the scope of the release.
