Choosing filament for the Snapmaker U1
The Snapmaker U1 has hotend up to 300°C, bed up to 100°C, an open frame, a stainless steel nozzle as standard and 4 independent toolheads support. That decides which filaments it prints well as it comes, and which need an upgrade first.
Out of the box it handles PLA, PETG and TPU. The lists below are the cheapest of each in stock on Amazon UK and Eryone UK right now, sorted by price per kilogram and filtered to the right diameter.
ABS, ABS-CF, ASA, Nylon and PC warp and split in a draught, so on an open-frame printer like the Snapmaker U1 they need an enclosure.
PLA Glow, PLA-CF, PETG-CF and ABS-CF are abrasive and wear out the stainless steel nozzle the Snapmaker U1 comes with; fit a hardened steel nozzle first.
An enclosure or a draught-free room helps with larger PETG prints.
An enclosure or a draught-free room helps with larger PETG-CF prints.

Common questions
What is the best filament for the Snapmaker U1?
PLA for most prints: it prints on the Snapmaker U1 as it comes, barely warps and is the cheapest to buy (the cheapest reel in stock on Amazon UK and Eryone UK is £7.12/kg right now). For parts that need more strength, heat resistance or flex, it also prints PETG and TPU without upgrades.
Can the Snapmaker U1 print ABS?
Not as it comes. ABS warps and splits in a draught; the Snapmaker U1 is an open-frame printer, so it needs an enclosure.
Can the Snapmaker U1 print ASA?
Not as it comes. ASA warps and splits in a draught; the Snapmaker U1 is an open-frame printer, so it needs an enclosure.
Can the Snapmaker U1 print PETG?
Yes. PETG prints on the Snapmaker U1 as it comes: set the nozzle to 230-260°C and the bed to 65-85°C. An enclosure or a draught-free room helps with larger PETG prints.
Can the Snapmaker U1 print TPU?
Yes. TPU prints on the Snapmaker U1 as it comes: set the nozzle to 210-240°C and the bed to 30-50°C. Flexible filament jams in the 4 independent toolheads; feed it from the external spool holder instead.
Can the Snapmaker U1 print Nylon?
Not as it comes. Nylon warps and splits in a draught; the Snapmaker U1 is an open-frame printer, so it needs an enclosure.
Can the Snapmaker U1 print PC?
Not as it comes. PC warps and splits in a draught; the Snapmaker U1 is an open-frame printer, so it needs an enclosure.
Can the Snapmaker U1 print carbon fibre filament?
Only after fitting a hardened steel nozzle. Carbon fibre, glass fibre and glow-in-the-dark filaments quickly wear out the stainless steel nozzle it comes with.
Do I need a filament dryer for the Snapmaker U1?
Not for PLA, but TPU soaks up moisture from the air and print stringy and weak when wet. A dryer that reaches 70°C covers it; the drying chart has the time for each.
How big can the Snapmaker U1 print?
Up to 270 × 270 × 270 mm. For a big print, check the slicer's filament estimate against what is left on the reel before you start.
