The turbofan engine is a representative system that highly integrates science, technology, engineering, and mathematics, encompassing extensive mechanical knowledge. Based on this characteristic, Vortrixe has launched the Teching Turbofan Trio product line, providing hands-on assembly model kits for mechanical beginners and enthusiasts seeking STEM learning opportunities.
Within the Teching Turbofan Trio, the largest model, DM119, is a top-selling item. Many mechanical enthusiasts who have purchased, assembled, and experienced it have highly praised its design and structural fidelity. However, this product presents a relatively higher barrier for mechanical beginners in terms of both price and assembly difficulty.
To lower the entry barrier for mechanical beginners and allow more people to experience high-quality, highly accurate turbofan assembly models firsthand, the DM121 Medium Turbofan Model and DM122 Mini Turbofan Model were developed based on the DM119 design.
While retaining the core mechanical design, the DM121 and DM122 models optimize assembly difficulty and offer greater value for money. This allows more enthusiasts to easily get started, enjoy the fun of assembly, and learn relevant mechanical knowledge during the process.
Which Teching Turbofan Model Is Right for You DM119, DM121, or DM122
