The FlashForge AD5X multi-colour 3D printer has been discounted to $210.01 at AliExpress as part of the retailer's Back to School Sale, using the coupon code "YUSAF23". The deal is notable because the same model normally retails for around $349 on Amazon, making this one of the cheapest entry points into multi-material 3D printing, a feature that typically pushes prices well above budget-level machines.

The AD5X is FlashForge's most affordable printer with integrated multi-material capability, allowing up to four filament colours or types to be used in a single print via an intelligent, automatically managed spool system. It features a CoreXY structure for improved speed and precision, a metal build, an 8.7-inch cubed open print bed, a 4.3-inch touchscreen, auto-levelling and vibration compensation, and can reach print speeds of up to 600mm/s. The unit ships free from the US via FlashForge's official AliExpress store, arriving within one to two weeks, though buyers need to be signed in to see shipping options.
