What slicer to use for the Snapmaker U1
Use OrcaSlicer, ElegooSlicer, or Kiri:Moto: each has a ready-made profile for the Snapmaker U1.
We only list slicers you can use in the SimplyPrint cloud, so there may be others for the Snapmaker U1.
Cloud-Based Slicer for Snapmaker U1: Use OrcaSlicer Online
Use OrcaSlicer and other slicers - directly in your browser with SimplyPrint's online cloud slicer. No installation required. Slice your Snapmaker U1 models from any device, anywhere in the world!
Automatic Profile Updates: Profiles are automatically checked and fetched from the slicer GitHub repositories every day, as well as from our own open-source community-driven slicer profile database. This ensures you always have access to the latest profiles.
Note: Other slicers, such as Simplify3D, ideaMaker, SuperSlicer and KISSlicer, aren't in our cloud, so we don't track their profiles. They may still work well with your Snapmaker U1: check the slicer's own documentation or forums for a profile. You can also contribute profiles to our open-source slicer profile database on GitHub.
The app for the Snapmaker U1
Use SimplyPrint as the app for your Snapmaker U1: watch and run it from your phone or any browser, slice in the cloud, and keep it next to your other printers. It's free to start. Snapmaker's own app is Snapmaker App.
There's no plate swapper or auto-ejection kit for the Snapmaker U1 in SimplyPrint yet, but AutoPrint can still keep it printing: once the plate is clear, it starts the next job from your queue.
CoreXY printers push their prints off
The Snapmaker U1's bed only moves up and down, so the usual way to automate it is a G-code routine that lets the toolhead push the cooled print off the front of the plate before the next job starts.

What filament can the Snapmaker U1 print?
Filament compatibility for the Snapmaker U1: the materials it can handle, judged from its hotend, bed, chamber and enclosure.
Filament
Suitability
Notes
PLA
Great
The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required.
PETG
Great
Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed).
TPU & flexibles
Great
The direct-drive extruder feeds flexible filament well. Print slowly for clean results.
ABS & ASA
With care
The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints.
Nylon (PA)
With care
Possible with care - an enclosure and very dry filament are essential.
Polycarbonate (PC)
With care
On the edge - PC really wants an enclosed, hot chamber to avoid warping.
Carbon-fiber & glass-filled
With care
Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle.
Tip: this is a general guide from the printer's specs - always check your filament's recommended settings. With SimplyPrint you can save a profile for each spool and track exactly what filament you have in stock.
Best filament for the Snapmaker U1
Filaments the Snapmaker U1 prints well, Snapmaker's own first, then the best known.
Tested a beta unit and found the U1 fast, precise and frugal with filament, producing clean multicolor prints faster than the reviewer's Bambu Lab P1P because tool swaps take seconds. Caveats are early-adopter rough edges, since it was Kickstarter-only at the time, and no fully enclosed lid at the base price.
“The Snapmaker U1 is the affordable tool changer we’ve all been waiting for, one with both speed, precision, and respect for your filament budget.”
Enjoyed how the U1 speeds up multifilament printing and rated its print quality, design and small desktop footprint highly. Notes it is still an open printer with the enclosure an added cost, only 0.4 mm nozzles at the time, and would have liked a built-in filament drying option.
“I've really enjoyed using the Snapmaker U1 as it opens up a world of possibilities for multifilament printing.”
Aurora Tech · July 18, 2026
Long-term review after more than 1,000 hours: it consistently printed faster with better quality in his single-color and multicolor tests, and he moves it to second place on his recommendation list with 87.5 out of 100. A dual-nozzle Bambu printer is the closer rival for two-material work and engineering filaments.
Maker's Muse · November 2, 2025
Review of a production unit by a skeptic who ends up impressed. For single-material printing the Bambu A1 or A1 Mini are still the best budget picks, but for multicolor or multi-material without purge waste the U1 makes much more sense. Cautions that other reviewers saw less reliable units.
Teaching Tech · October 17, 2025
First impressions of the production model: sees it as a slightly larger, more open-source tool changer take on the Bambu X1 Carbon, at a price that will attract many buyers. Notes the LAN mode and USB printing, and wants Snapmaker to publish its Klipper changes.

Snapmaker is a Shenzhen company founded in 2016, built around machines that swap tool heads; its Original, 2.0 and U1 machines were launched on Kickstarter. It sells the U1, a CoreXY printer with four tool heads that change in about five seconds for multi-colour printing, and the Artisan, which combines 3D printing, laser engraving and CNC carving. Its buyers are makers, hobbyists and small workshops.

Snapmaker is mostly open: the U1 runs Klipper with a local Fluidd interface and published source, and nearly every part is sold separately. Its proprietary hotends and RFID system are the closed parts.
Firmware and custom firmware ●●●●●
The U1 runs modified Klipper, Moonraker and Fluidd. Snapmaker published its changes on GitHub under GPL-3.0 on 30 March 2026, about three months after Kickstarter deliveries finished. Firmware for the Snapmaker 2.0 and, since August 2026, the Artisan controller is also on GitHub under GPL.
[1][2][3][4]
Local control and integrations ●●●●●
The U1 runs Klipper, Moonraker and Fluidd on the printer and prints from Snapmaker Orca over Wi-Fi or from a USB drive, so other software can use Moonraker's documented API; Snapmaker publishes its Moonraker changes on GitHub. For the Artisan, Snapmaker documents its G-code commands and has Luban pass jobs from OrcaSlicer over the OctoPrint protocol. The Snapmaker app is for remote monitoring.
[1][5][13][14][15]
Third-party filament, slicers and parts ●●●●●
Third-party 1.75 mm filament works and the U1 is supported in OrcaSlicer, but its RFID filament recognition is proprietary and only reads Snapmaker spools, and its hotends are proprietary one-piece units. Snapmaker documents using Cura, OrcaSlicer and PrusaSlicer with its older machines.
[1][6][7]
Repairs and spare parts ●●●●●
Snapmaker's shop sells most U1 parts on their own, including the main board, heated bed, extruder motor, toolhead board, belts, fans and touchscreen, and its wiki has replacement guides such as the U1 XY motor. Hotends can only be replaced as a whole unit.
[8][9][1]
Data and privacy ●●●●●
Cloud features need a Snapmaker account. The privacy policy says personal data is stored on servers in the United States, may be shared with affiliates and third parties in China for some functions, and some data is kept for three years.
[10]
Community and documentation ●●●●●
Active forum and a wiki with detailed FAQs and guides, firmware and slicer sources on GitHub, and frequent public updates and livestreams during the U1 campaign.
[1][2][11]
Pros
The U1's four-head tool changer wastes little filament on colour changes.
Klipper-based U1 with a local Fluidd interface and published firmware source.
Nearly every U1 part is sold separately, with replacement guides.
Has delivered all of its Kickstarter campaigns, the U1 ahead of schedule by its own account.
Cons
U1 hotends are proprietary one-piece units.
RFID filament recognition is proprietary and only works with Snapmaker spools.
U1 firmware source came after deliveries, at the end of a self-set deadline.
Personal data is stored in the US and may be shared with affiliates in China.
The U1 does not work with Luban, so owners of older machines need a different slicer.
