The Bambu Lab upgrades actually worth buying

Expert upgrade advice for A1, A1 mini, P1S and X1C owners. Every pick is organized by the problem it solves — and about half the time the answer is an inexpensive part rather than a new printer.

What wins in each category

The top pick from every roundup on the site. Each one links to the comparison it won, where you will also find who it is wrong for.

Six things people upgrade

  • A large enclosed dual-nozzle 3D printer with its chamber door open

    Printers

    Which Bambu Lab printer to step up to

    You already own one. The question is not which printer to buy, it is whether a new machine fixes the thing that is actually bothering you — and usually it does not.

  • A stack of multicolored filament spools representing a four-spool material system

    AMS & Color

    AMS and multi-color printing

    The AMS is the best-value upgrade Bambu sells and the most misunderstood. Here is what each version does, which one fits your printer, and when a dryer is the better buy.

  • Clear panels forming an enclosure around a 3D printer frame

    Enclosures

    Enclosures, ABS and ASA

    An enclosure is not a magic box. It traps heat, dust and some noise — and which of those three you care about completely changes what you should buy.

  • A small machined metal nozzle held against a neutral background

    Nozzles & Plates

    Nozzles, hotends and build plates

    The two cheapest parts on the printer decide more about your print quality than anything else you could buy. Here is which one to change and when.

  • Filament spools arranged ready for drying

    Filament Drying

    Filament dryers and storage

    Wet filament imitates six other faults convincingly. Drying is the cheapest thing you can do to a print, and the one most owners try last.

  • A stack of multicolored filament spools representing a four-spool material system

    Upgrades

    Bambu Lab upgrades and mods

    Most upgrade lists are shopping lists. This one is organized by the problem each part solves, because about half the popular upgrades fix nothing you have.

How this site is different

  • Written for owners, not shoppers

    Every competitor in this niche writes for first-time buyers; one of them literally positions on being beginner-friendly. You already know what a nozzle is. Nothing here explains that.

  • No test lab, and we say so

    There is no measurement rig behind this site and no benchmark data. You will never read 'in our testing' here, because it would not be true. What you get is published specs, cited, plus judgment.

  • Prices live on Amazon

    A price typed into an article is wrong within a month. Every button sends you to the live listing instead of quoting a figure we cannot keep honest.

  • Every pick says who it is wrong for

    A roundup where everything suits everyone is a catalog. The 'wrong for' line is mandatory on every recommendation on this site.

    Bambu Lab P1S vs P2S

    The P2S adds a touchscreen and a quick-swap nozzle and no build volume. When that is worth a new machine and when a far cheaper part does the same job.

    Upgrading from a P1S

    The two reasons to replace a P1S and the four cheaper parts that cover everything else, with the arithmetic laid out.

    Print quality triage

    The central symptom-to-cause table for the whole site, with the two free checks that resolve most problems before any purchase.

Latest

  • The best Bambu Lab printer to step up to in 2026

    One pick per upgrade situation, from the P1S owner who should keep their machine to the owner who genuinely needs the H2 build volume.

  • Bambu Lab A1 mini

    What the A1 mini is genuinely good at, the open-frame limit that eventually pushes owners to upgrade, and why it is worth keeping anyway.

  • Bambu Lab A1

    What the A1 does well, the open-frame limit that defines every upgrade decision from here, and the two routes past it.

  • Bambu Lab P1P

    Why the P1P is a P1S project rather than a lesser printer, and whether the official enclosure kit is the right spend.

  • Bambu Lab P1S

    What the P1S already does well, the three things it genuinely cannot do, and which cheap part fixes each complaint instead of a new machine.

  • Bambu Lab P2S

    The two things the P2S genuinely adds over a P1S, the things it does not, and what the same money buys as upgrades instead.

  • Bambu Lab X1-Carbon

    What the X1C still does better than a P1S, why it is no longer the flagship, and why that makes it a good used buy and a poor new one.

  • Bambu Lab X2D

    What a reported 65 C actively heated chamber fixes that a P1S cannot, and the two honest caveats on a machine released in April 2026.

How this site is funded

Plate & Spool is funded by Amazon affiliate commissions. If you buy something through a link here, this site earns a small commission at no extra cost to you. That is the entire business model — no sponsored reviews, no paid placements, no manufacturer supplying us with hardware in exchange for coverage.

It does not change what gets recommended. Several pages here conclude that the right answer is to keep the printer you own and spend a fifth of the money, which earns less than recommending a new machine would. That is the point.
