The Ultimate Bambu Lab A1 Upgrade Guide (2026)
The Bambu Lab A1 is one of the best printers you can buy out of the box. Fast, reliable, and surprisingly capable for the price. But if you've been printing for a while, you've probably noticed a few limitations — and you're not alone.
This guide covers every meaningful upgrade for the Bambu Lab A1, ranked by real-world impact. We've tested most of these ourselves and sourced the rest from the r/BambuLab community. No fluff, no affiliate filler — just what actually makes a difference.
🏆 Tier 1: Game-Changers (Do These First)
1. Automatic Multi-Filament Swapper — Swapmod Kit
Impact: ⭐⭐⭐⭐⭐ | Difficulty: Easy | Cost: ~$169
If you only do one upgrade, make it this one.
The Bambu A1 supports the AMS Lite for multi-color printing, but filament changes are slow and the system requires constant manual intervention for farms or long unattended prints. The Swapmod Kit solves this with a fully automatic filament swap mechanism that works independently of the AMS.
What it does:
- Enables fully automatic filament swapping between print jobs
- Dramatically reduces idle time between prints
- Ideal for print farms, batch production, or anyone printing multiple colors or materials regularly
- Installs in under 20 minutes with no permanent modifications
Who it's for: Anyone running more than one print job per day, multi-color printing enthusiasts, or small print farms.
2. PEI Spring Steel Build Plate
Impact: ⭐⭐⭐⭐⭐ | Difficulty: Easy | Cost: ~$12-69
The stock Bambu A1 build plate works fine out of the box, but it degrades faster than most people expect — especially if you're printing frequently. A PEI spring steel plate is the single best quality-of-life upgrade for daily printing.
- First-layer adhesion improves significantly — less warping, better bed adhesion across materials
- Part removal becomes trivial: cool the plate, flex it slightly, parts pop off
- Lasts 5x longer than stock surfaces
- Works with PLA, PETG, TPU, and most engineering filaments
3. Hardened Steel Nozzle / Hotend Kit
Impact: ⭐⭐⭐⭐⭐ | Difficulty: Medium | Cost: ~$20-45
The stock brass nozzle on the A1 works great for standard PLA and PETG. The moment you start printing carbon fiber, glass-filled, or abrasive filaments, it degrades fast — sometimes within a single spool.
Signs your nozzle needs replacing: inconsistent extrusion, stringing on clean models, poor first-layer adhesion (after ruling out bed issues).

🥈 Tier 2: Meaningful Upgrades
4. Filament Dry Box / Vacuum Storage
Impact: ⭐⭐⭐⭐ | Difficulty: Easy | Cost: ~$15-45
Moisture is the silent killer of print quality. If you've ever wondered why a spool that printed perfectly six months ago now produces bubbling, stringing, or weak layers — moisture absorption is almost certainly the cause.
Our vacuum-sealed storage bags with USB pump extend filament life dramatically and keep your spools print-ready at all times.
5. Enclosure (DIY or Commercial)
Impact: ⭐⭐⭐⭐ | Difficulty: Medium | Cost: $50-200
The A1 is an open-frame printer, which limits its ability to print temperature-sensitive materials like ABS, ASA, and PC without warping. An enclosure retains heat, reduces drafts, and dramatically improves results with engineering filaments.
6. Camera Upgrade / Remote Monitoring
Impact: ⭐⭐⭐ | Difficulty: Easy | Cost: ~$30-80
The built-in camera on the A1 is functional but limited in resolution. For print farm operators or anyone who wants reliable remote monitoring, an external camera with better resolution and wider field of view is worth considering. Pairs well with OrcaSlicer and SimplyPrint for multi-printer management.
🥉 Tier 3: Nice to Have
7. Cable Management & Drag Chain Upgrades
Impact: ⭐⭐ | Difficulty: Medium | Cost: ~$10-30
Printable on the A1 itself. The community has produced excellent cable management solutions on Printables and Makerworld. Reduces wear on cables over time and makes the machine look significantly cleaner.
8. LED Lighting Strips
Impact: ⭐⭐ | Difficulty: Easy | Cost: ~$10-20
The A1's stock lighting is adequate but not great for monitoring print quality. A simple LED strip improves visibility for remote monitoring cameras and makes it easier to catch print failures early.
9. Spool Holder Upgrades
Impact: ⭐ | Difficulty: Easy | Cost: Free (printable)
The stock spool holder works, but side-mount holders reduce footprint and allow larger spools. Dozens of designs available free on Printables.
Upgrade Priority: Where to Start
If you're new to upgrading the A1, here's the order we'd recommend:
- PEI build plate — immediate quality of life improvement, low cost
- Filament storage — protects your existing filament investment
- Swapmod Kit — if you print frequently or want to run a farm
- Hardened nozzle — when you start experimenting with abrasive filaments
- Enclosure — when you want to print ABS/ASA/PC reliably
Final Thoughts
The Bambu Lab A1 is already an excellent machine. These upgrades don't fix problems — they extend what's possible. The biggest gains come from the Swapmod Kit (if throughput matters to you) and the PEI plate (if you print daily).
