Build plates are one of those upgrades that quietly decide whether your printer feels easy to live with or slightly annoying every week. On the A1 Mini, the choice between a dual-surface aftermarket plate and an official smooth plate is really a choice about what you want the machine to do most often.
This comparison is for buyers deciding between the 3DHUB Smooth PEI Build Plate for Bambu A1 or A1 Mini and the Bambu Lab Smooth PEI Plate for A1 Mini. Both are reasonable options for the same printer family, but they solve slightly different problems.
Short answer: buy the 3DHUB plate if you want one flexible plate that gives you more day-to-day versatility. Buy the Bambu smooth plate if your priority is cleaner bottom surfaces, a smoother finish, and an official plate that fits a more specific workflow.
Quick comparison summary
- Buy the 3DHUB plate if you want a more flexible everyday plate with dual-surface value and broader ?leave it on the printer? appeal.
- Buy the Bambu smooth plate if you specifically want smoother bottom finish on A1 Mini prints and care less about texture-side flexibility.
Fast-scan compare
| Category | 3DHUB dual-sided plate | Bambu smooth PEI plate |
|---|---|---|
| Best fit | buyers who want one plate that covers more everyday printing situations | buyers who care specifically about cleaner, smoother bottom surface appearance |
| Main strength | versatility and value from a dual-surface setup | smooth-bottom finish and official Bambu fit for that use case |
| Main tradeoff | not as purpose-built if your whole goal is a smoother presentation face on the underside | more specialized and less versatile if you also want textured-side flexibility |
| Who should skip it | buyers who already know they want official smooth-bottom results first | buyers who want one general-purpose plate instead of a finish-specific add-on |
Where the 3DHUB plate wins
The 3DHUB plate makes more sense for the buyer who wants one plate to handle a wider mix of prints. If your A1 Mini does a little of everything ? prototypes, organizers, brackets, household parts, and general hobby printing ? a dual-sided plate is easier to justify because it gives you more freedom without immediately pushing you into a specialized setup.
That matters because most people are not chasing a perfect presentation bottom surface on every print. They are trying to keep adhesion predictable, parts easy to remove, and workflow simple. The broader everyday value case is where the 3DHUB option pulls ahead.

Where the Bambu smooth plate wins
The Bambu smooth PEI plate wins when finish quality on the underside is the real point. If you print parts where the visible bottom face matters ? small display parts, cleaner product-like pieces, labels, flat decorative surfaces, or parts that simply look better without texture ? the official smooth plate is the more direct answer.
It is also easier to recommend when you already know what you want from the plate. This is less about flexibility and more about a specific print result: smoother bottoms and a cleaner visual finish.

Which one makes more sense for everyday A1 Mini printing?
For everyday printing, the 3DHUB plate makes more sense for more people. A dual-surface plate is easier to leave on the machine as the default because it covers a wider range of jobs. If your A1 Mini is a general-use printer, versatility usually beats specialization.
The Bambu smooth plate makes more sense when the bottom finish itself is part of the buying decision. If you have already looked at textured bottoms and decided you want something cleaner, then the official smooth plate is the sharper tool for that exact job.
When to buy the 3DHUB plate
- You want one plate that stays useful across many print types.
- You value flexibility more than chasing one specific bottom-surface look.
- You want the stronger all-around pick for a mixed-use A1 Mini.
When to buy the Bambu smooth plate
- You specifically want smoother bottom finish.
- You print display-facing or presentation-sensitive parts.
- You would rather add a purpose-built official plate than rely on one do-everything option.
Final recommendation
Buy the 3DHUB Smooth PEI Build Plate for Bambu A1 or A1 Mini if you want the better all-around everyday choice. Buy the Bambu Lab Smooth PEI Plate for A1 Mini if the smoother bottom surface is the reason you are shopping in the first place.
