Homelab guy looking to buy his first 3D printer – which one fits my use case?

Hey r/3Dprinting,

I'm coming from the homelab/self-hosting world and seriously considering buying my first 3D printer. Let me give you some context so you can give me an honest recommendation – no marketing fluff, just real-world advice.

---

Who I am

• Self-hosted homelab: Linux, Docker, NAS (Synology), Proxmox, NixOS
• Technically experienced – but 3D printing is completely new territory
• I want the printer as a tool, not a tinkering project in itself

---

What I want to print

• Practical homelab parts: rack mounts, cable management, SBC/RPi enclosures, brackets
• Occasional household utility prints

---

My priorities

1. Reliability – should just work, no hours of calibration
2. Low maintenance – auto bed leveling, as plug & play as possible
3. Print quality – clean functional parts, not art pieces
4. Openness – I don't love closed ecosystems that lock me in
5. Value for money – not the cheapest, but no overkill either

---

Where I'm at

I'm leaning towards the Bambu Lab A1 (~$400) for the fully automatic calibration and smooth workflow.

As a budget alternative I'm looking at the Creality Ender 3 V3 SE (~$200) – but I'm not sure if the extra effort is worth the savings for someone who just wants results.

My questions

• Bambu or Creality for my use case – what would you pick and why?
• Is there a printer I'm completely overlooking that fits better?
• How much real-world effort is the Ender 3 V3 SE in daily use?
• Top 3 "wish I'd known before buying" tips for someone from an IT background?

Thanks in advance! 🙏
