Train 3D printing SLA custom rapid prototyping

Model trains are not only exquisite collectibles, but their appearance is also completely scaled down and imitated according to the trains of various countries and eras, which is authentic and historical. The outer shell is mostly made of high-grade engineering plastic B, with built-in exquisite motors, metal weight, and complete Scale down. The railway is also scaled down according to the real railway and is made of zinc alloy. The electric current is transmitted to the railway through the controller to drive the head motor. The model train will move like a real train and can move forward and backward at an adjustable speed. If there are electric lights, it will Light up or switch lights as the train moves, and some can also add sound effects or smoke to make them come alive like real trains.
