Bambu Lab A1 vs A1 Mini: Which Should You Buy?

Some links on this page are affiliate links. If you buy through one, Planet 3DP earns a small commission at no extra cost to you. It never changes what we recommend. How this works.

The Bambu Lab A1 and A1 mini share the same toolhead, the same speed and the same AMS lite multicolor option. The difference is size. The A1 prints 256 mm cubes and the mini 180 mm, and the A1 bed heats to 100°C against the mini’s 80°C. Pick the A1 if you want room to grow. Pick the mini if desk space and price come first.

Nick owns several of each and still prints on his first A1 and his first A1 mini. He hasn’t filmed the two side by side on the same print, so this page compares them on Bambu Lab’s own specs and today’s prices, and adds what he has said about living with both.

Bambu Lab A1 vs A1 mini: the specs side by side

The real difference is the bed

Everything that decides print quality is shared. Both use the same all metal hot end, the same 500 mm/s top speed and the same full auto calibration. So the question is mostly what you want to print and where the printer will live.

The A1’s 256 mm cube is the same build volume as Bambu’s enclosed P1S and P2S. Helmets, large cosplay parts and big plates of small parts fit. The mini’s 180 mm cube suits figures, gifts and most household fixes, and it sits on a desk at 347 by 315 mm.

The bed temperature gap matters too. The A1 bed reaches 100°C and the mini’s 80°C. Bambu lists the same ideal filaments for both, PLA, PETG, TPU and PVA, and marks ABS, ASA, PC and PA as not recommended on either. Nick says the same about the A1: it’s an open frame printer, so ABS and ASA are out. That’s at 10:20 in his beginner printers video.

Is the Bambu Lab A1 safe?

This comes up because of the 2024 recall. In January 2024 Bambu Lab said some A1 heatbed cables were getting damaged where the cable meets the base, which could affect temperature readings and cause power loss or even short circuits. In the same post it said the A1 mini is not affected. That’s Bambu’s own post from January 28, 2024.

A week later Bambu widened it to a recall of every A1 on the market, whatever its condition, and asked owners to stop using them until it was fixed. Store buyers could take a full refund plus an 80 dollar voucher, or keep the printer, get a new heatbed and a 120 dollar voucher, and add six months to the warranty. Bambu expected the batch with the revised cable around May 2024. The details are in its February 4, 2024 update.

The A1 sold today lists an upgraded heatbed cable on Bambu’s store page, with Kevlar reinforcement, thicker insulation, nylon sleeving and a longer strain relief. Nick has run several A1s for thousands of hours with minimal issues, in his words. If you’re buying used, ask whether the recall work was done.

Which one should you buy?

Choose the A1 if you want one printer that won’t feel small in a year. The 256 mm bed fits larger parts and full plates, and the 100°C bed gives you more headroom. At 299 dollars it’s the same build volume as Bambu’s enclosed machines for a lot less.

Choose the A1 mini if it has to live on a desk, it’s a gift for a beginner or a kid, or most of what you print fits in a 180 mm cube. It’s the cheapest way into Bambu’s printers and app, and in the Black Friday sale it’s 199 dollars.

Both are open frame printers, so neither is the pick for ABS or ASA. And whichever you pick, Nick’s advice in his beginner video is that a solid low cost printer like these is the smart first step, because most people end up with a second printer later.
