Which one should I buy?

Almost certainly the A1 ($399). The X1E is an industrial engineering printer costing 4× more, built for PA-CF and PC production, not hobbyist printing.

A1

  • 4× cheaper at $399, far better value for PLA/PETG/TPU printing
  • Touchscreen and quick-swap nozzle, easier consumer experience
  • No enclosure needed for everyday materials, simpler setup
  • AMS Lite compatible for 4-color prints without complexity

X1E

  • Active 60°C chamber heating, required for PA-CF, PC, and PPS engineering materials
  • Industrial-grade HEPA + VOC filtration, meets workplace safety requirements
  • Fully enclosed dry filament path, prevents moisture absorption in hygroscopic materials
  • Enterprise fleet management, built for multi-printer production environments
Short answer

If you're comparing these two, you almost certainly want the A1. The X1E is an enterprise engineering printer targeting PA-CF, PC, and PPS production. The A1 is a consumer printer for PLA/PETG. They don't meaningfully compete.

The A1 is excellent at what it does: PLA, PETG, and TPU for hobbyists. It's not designed for engineering materials and doesn't need to be. Practically no one should be choosing between these, if you're a hobbyist, get the A1.
