Snapmaker U1 Review: 4-Toolhead Multicolor 3D Printer

The Snapmaker U1 takes a different approach to color printing than almost everything else on the market: instead of one toolhead swapping between filaments, it runs four independent toolheads. Here's what that means in practice, and who it's actually for.

What is the Snapmaker U1?

The Snapmaker U1 is an FDM 3D printer built around Snapmaker's SnapSwap system: 4 independent toolheads instead of a single nozzle that swaps filament spools mid-print. It's priced at 5,550 SAR and is currently in stock at Black Arrow 3D.

How SnapSwap differs from filament-swap systems (like AMS)

Most multicolor FDM printers, including Bambu Lab's AMS and AMS Lite, use one toolhead and feed different filament spools into it one at a time. Every color change means purging the old filament out of the nozzle before the new color can print cleanly, which wastes material and adds time.

The U1's SnapSwap system instead keeps 4 separate toolheads, each pre-loaded with its own filament. The printer switches which toolhead is active rather than swapping filament through one nozzle. In principle, this cuts down on the purge waste that filament-swap systems produce — though it comes with a larger, more mechanically complex machine as a trade-off.

Who the Snapmaker U1 is for

Its CoreXY frame, 500 mm/s top speed and 4-toolhead color system make it best suited to people producing colorful pieces regularly rather than printing the occasional single-color part: content creators, small print shops, retailers making multicolor figurines and gifts, and serious hobbyists who've outgrown single-color or filament-swap printing. The 270 x 270 x 270 mm build volume comfortably covers gifts, figurines, logos and most desk-sized products.

Snapmaker U1 vs Bambu Lab AMS — which should you buy?

If you're just starting out with multicolor printing and want the lowest entry cost, an AMS Lite combo on the Bambu Lab A1 mini or A1 is the more established, lower-cost route. If you print color-heavy work often enough that purge waste and color-change time matter, and you don't mind a larger machine and higher upfront cost, the Snapmaker U1's 4-toolhead approach is built for exactly that.
