The verdict
Buy the A1 Combo.
9.2/10 vs Orange 4K's 6.4/10, and it wins 4 of 5 categories. One printer. This one. The A1 Combo does multi-color, does speed, does software polish, all at a price that embarrasses the competition. The open frame is the only real compromise and most people won't care.

Teal wins the row.

What owners say
The A1 Combo is the printer I recommend to literally everyone who asks.
A1 Combo owner, r/3DprintingMulti-color out of the box at this price is insane. Changed how I think about printing.
A1 Combo owner, Make Anything (YouTube)Bambu did it again, this is the new gold standard for consumer 3D printing.
A1 Combo owner, All3DPGot this to test if resin was for me. Spoiler: it was. Upgraded to a Mars in 3 months.

Pros & Cons
A1 Combo
- +AMS Lite ships in the box, not as a separate purchase
- +Bambu Studio slices and sends in under a minute
- +500mm/s speed that actually holds up at 0.2mm layers
- −Open frame means ABS is borderline without an enclosure
- −AMS Lite tops out at 4 colors; want more, buy a different system
Orange 4K
- +This is the absolute floor for resin printing
- +WiFi at this price is genuinely surprising
- +4K resolution is enough to see if resin is your thing
- −118x66mm build plate: one mini at a time, if they're small
- −4K resolution is dated next to 9K and 12K competitors

- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
