The most significant difference between the Halot-One Pro and the Ender 3 is that the Halot-One prints with resins, and the Ender 3 are filament printers that use things like PLA and ABS. As a result, the Ender 3 is an ideal entry to a 3D printer, as it's just $189.00, and the Ender 3 is a bit more expensive with a smaller build volume (more specialized).
