The Honest Guide to the Bambu Lab AMS 2 Pro (and How to Make It Work with H2D, H2D Pro, X2D, or P1S)

The AMS 2 Pro is the multi-material system that unlocked Bambu Lab's true 16-color potential. But it's also the product we get the most confused-customer emails about — specifically when people try to pair it with the newer X2D, H2D Pro, or P1S. This guide covers what the AMS 2 Pro does, how it compares to AMS lite and AMS HT, the secret "soft-bundle" parts list, and how to make sure the unit you buy actually works with the printer you already own.

What the AMS actually does

AMS stands for Automatic Material System. Drop in up to four spools, the printer auto-loads, auto-cuts, hot-swaps filaments, and buffers. With two AMS units on one printer, you can print up to 16 colors in a single job — no manual swaps, no color contamination.

Bambu Lab makes three AMS flavors. Pick the one your material + workflow needs:

Compatibility: which AMS pairs with which printer

Two changes worth flagging vs older guides:

• The X1E is discontinued. If you have an X1E, the soft-bundle parts list below still applies — but we no longer recommend buying an X1E new in 2026. Go X2D or H2D Pro
• The X2D is the new accessible dual-nozzle printer. It supports 1 or 2 AMS 2 Pro units natively. The X2D Print More Bundle ($1,149) ships with 2× AMS 2 Pro for up to 16-color printing.

The X1C/P1S/P1P + AMS 2 Pro soft-bundle, explained

When Bambu Lab launched the AMS 2 Pro, it was designed for the new-generation printers (P2S, H2D, H2C). The X1C — still very popular in 2026 — needs four extra parts to talk to the AMS 2 Pro properly. The good news: AMS 2 Pro Upgrade Kit With Buffer  and AMS 2 Pro Upgrade Kit 2 with AMS Hub

When you DON'T need an AMS

Be honest with yourself — AMS is a luxury until you actually do multi-color or runout-tolerant prints. Skip the AMS if:

• You mostly print single-color functional parts.
• You're buying a printer for an elementary classroom that doesn't need color storytelling.
• You're buying the AMS "just in case" — that's an extra $299 that buys a lot of filament.

The right time to add an AMS is when you find yourself wishing a print had multiple colors, or when you've had a print fail because a spool ran out at hour 8.

Setting up AMS 2 Pro with an H2D for the first time

1. Plug the AMS into the printer via the bundled cable.
2. Calibrate the AMS hub position via Bambu Studio → Device → Calibration.
3. Load spools; the AMS will purge each path on first use.
4. Run the multi-color test print from the SD card; verify each color change is clean.

This takes about 15 minutes. If your first 4-color print has bleeds or partial color swaps, run the AMS dry-cycle cleaning routine (Maintenance → AMS).

Buying through INNOADDI

When you order any AMS 2 Pro from us, we automatically request the soft-bundle free parts from Bambu Lab and pack them with your shipment — no extra charge. Just tell us in the order notes how many of your AMS units are going to X1C or P1S printers so we can size the free-part allocation correctly.

FAQ

Can I run AMS lite AND AMS 2 Pro on the same printer?
No — pick one AMS per printer. The two systems are not interchangeable.

Will the AMS dry my filament?
AMS 2 Pro actively dries; AMS lite is just a sealed enclosure with humidity-control packets. AMS HT is the only one with a heated chamber for filament.

Can I use AMS HT and AMS 2 Pro on the same printer at the same time?
Yes, that's the engineering setup — AMS HT for high-temp materials, AMS 2 Pro for everything else.

How long does the order-to-soft-bundle-parts process take?
We submit the order to Bambu Lab; the parts ship with your printer order. No extra shipping.
