What owners say
The A1 without AMS is the best single-color printer you can buy at this price. Bar none.
A1 owner, r/3DprintingSame great hardware as the Combo, just without the color changer. Perfect for most people.
A1 owner, Make Anything (YouTube)Printed a half-scale bust in a single run. The Mega 8K S2 is in a class of its own.
Sonic Mega 8K S2 owner, r/resinprintingIf you sell resin prints, the Mega 8K S2 pays for itself fast. Batch printing changes everything.

Pros & Cons
A1
- +Full 256mm build volume, same as the Combo but $100 cheaper
- +Bambu's reliability, slicer, and support at $299
- +500mm/s speed that's calibrated and ready without tweaking
- −Open frame: ABS warping is a real problem without modification
- −No multi-color in the box: the Combo is $100 more and includes it
Sonic Mega 8K S2
- +330x185mm plate is the largest resin build area in the consumer market at this price
- +8K detail across the full plate without the hot spot degradation that plagues cheaper large-format LCDs
- +Dual tilt release on a plate this size prevents the vacuum seal failures that ruin large prints
- −$749 for a resin printer is a serious investment, plus $80-120 for a wash station to match
- −High resin consumption: a full plate run uses 400-500ml, which adds up weekly

- ELEGOO PETG filament, 1kgTougher and more heat tolerant than PLA, for parts that get handled or sit in the sun.
- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
