Wube Software, the developer behind Factorio, has released free 3D-printable models of in-game entities following a lengthy design and prototyping process that began in late 2024.
The project originated during playtesting for the Space Age DLC, when the team partnered with Prusa Research to create accompanying programs and presentations. At the event, team member Fearghall created a simple 3D model of the Wriggler creature, sparking the idea to develop printable Factorio models.
After the DLC’s release, the team spent months prototyping and iterating. Designer Jarosław led the effort by creating a grid-based system for placing entities that closely mirrored in-game placement. The focus settled on transport belts as the core concept, since they form the foundation of every factory. The team ultimately created two versions of most models: one with high precision for push-fit assembly, and another with greater clearance for permanent gluing or printer compatibility.
The final collection comprises 15 model sets containing 65 individual models distributed across 247 STL files, focusing on early-game content. Included entities range from inserters and chests to enemies like biters and spitters, the player character, and stone furnaces.
Development required extensive iteration. According to the source, many models underwent multiple rounds of refinement, with countless prototype prints created to test and fine-tune designs. A significant challenge involved adapting Factorio’s isometric perspective—which relies on creative visual tricks and specific angles—into three-dimensional printable objects. The team also had to solve FDM printing constraints, particularly managing support structures that could be visually distracting or difficult to remove.
Wube chose to release the models freely rather than create expensive collector’s items. According to the team, this decision reflected their identity as a software company and their appreciation for the community. The company also emphasized wanting to enable player creativity by allowing fans to download, modify, and iterate on the designs. The models are now available for anyone with a 3D printer to produce their own physical versions of Factorio entities.
