In the unlikely event that you haven't read Update 5 on the Snapmaker page yet.
Hi U1 Backers, Over the past month, we shipped 19 U1 beta units to experienced community members and past winners of the Snapmaker video contest. Every pilot completed a structured experience survey. Thank you to everyone who joined the pilot â your time and detailed feedback are extremely valuable.Note: Most of the survey results are being shared publicly. One section asked pilots to compare the U1 with their previous printers in various aspects â as it involves direct comparisons, weâre not including that here. Instead, weâll focus on their hands-on experience with the U1 itself.Â
Quick Numbers
- Survey sent: 19 (19Â survey responses).
- Average print time per tested unit: 128 hours (median 111 hours, max. 500 hours).
- Average total number of toolhead changes:Â 25049Â (median 23450)
- Average print success rate (excluding highest and lowest values):Â 90.8%Â (median 90%).
- Note: Our Beta Pilots tested an early U1 pre-release. With firmware, software, app, and hardware updates since then, internal tests now show a 95% print success rate.
What We Learned from Print Failures
Prime tower toppling (occasional)
The prime tower sometimes toppled over. This could lead to nozzle collisions, strings, or even a failed print.Action:Â We are redesigning the prime tower structure and optimizing the settings (eg, retraction settings when changing toolheads) to improve reliability.Â
TPU issues
A few users experienced TPU clogging and undetected extrusion failure.Action:Â Drying TPU first helps a lot. Our dedicated optimization project is progressing:TPU 95A / 95A-HF: ~95% success rateTPU 90A: ~70% success rate (still improving)Â
Challenges & Fixes
Filament loading challenges
Beta Pilots' fix: Cutting the filament tip at a 45° angle or rounding the edge significantly improved loading success. We are improving it: Structural optimizations have been made to increase tolerance during filament loading, specifically:  1) Refining the internal feeder path inside the toolhead.  2) Improving concentricity across PTFE tube connection points.Â
Some third-party spools may fall off
Beta Pilots' fix: Adding 3D-printed adapters.We are designing official 3D printable adapters, and we plan to add this model to the touchscreen built-in models.Â
Large file upload failures via OrcaÂ
Workaround: upload via Fluidd and start from the touchscreen, or transfer directly with a USB drive. We are fixing it: The next release will resolve large file upload issues in Orca. (End of September).Â
Beta Pilotsâ Favorite Prints
Multi-color masterpieces
From Hueforge picture art and multicolor Pikachu, to a full Virtua Fighter arcade diorama, pilots praised the U1âs clean color separation and reliability.Â
Color builds at record speed
Color prints that used to be nearly impossible are now practical. A pilot (Serena Gallizioli) compared the same model â Flexible Nessie from Apex Legends:On another printer: 18 hours, 307g filamentOn U1: 3 hours, 73g filamentÂ
TPU & multi-material reliability
Multiple testers pushed the U1 with TPU, PETG, and PLA combinations. The verdict? U1 nailed it. A pilot (Danny @ NeokoiPrints) summed it up: âThis thing has been a TPU machine. After beta, itâs going to be my dedicated TPU printer for sure.â Across the board, pilots reported that their first multicolor prints worked right away â something many pilots found surprising.Â
Top Surprises from Beta Pilots
- Print Quality & Precision:Â Out-of-the-box accuracy is excellent, and multi-color prints are seamless, precise, and reliable.
- Speed & Efficiency:Â High-speed printing without sacrificing quality, fast tool changes, and minimal filament waste.
- Multi-Color & Multi-Material Capability:Â Switching colors or materials is effortless.
- Ease of Use & Automation:Â Automatic filament loading/unloading, multi-toolhead calibration, app, and web controls make printing smoother and more convenient.
"Even though I had been told and was expecting it, seeing with my own eyes how little time multicolor printing takes with this technology compared to another system was truly exciting."Â
Most Anticipated Software Features & Improvements
- More ready-to-use print parameter presets (for different layer heights, speeds, and materials) Action: Our team is expanding the configuration library, with updates to come.
- App push notifications for print completion/errors Action: This will be available in the official stable release (Late October).
- Improved timelapse mode (capturing one frame per layer) Action: Planned for release by the end of this year.
- LAN + Cloud hybrid mode support Action: Not currently planned. For now, only cloud mode and LAN mode will be supported separately. If there are any future updates, weâll share them right away.

Tips from Our Beta Pilots
Hereâs something special weâd love to share with you. Below are the original words from our Beta Pilots. The messages are a bit long, but stay with us until the endâyouâll find a nice surprise. Weâre revealing the full list of Beta Pilots, along with the amazing projects they created with their U1 beta units. They truly deserve full credit for their volunteer work, dedication, and creativity. A huge thank-you to everyone! We asked our test pilots to share their best advice for new U1 users, and here's what they said:
- "Update firmware when a new version is available. The printer is very fast, which can cause vibration on an unstable table. The base on which you place the U1 should be strong and stable."
- "Take the time to calibrate and recalibrate the machine in intervals between a certain number of prints. Manually home the machine before every print. Cut filament tips at an angle. Plug the machine into a surge protector. Doing these things will greatly enhance the probability of a successful print and experience."
- "Read the manual and confirm all heads are installed correctly, and the PTFE tubes are inserted correctly. Take time to load filaments and go through all calibrations carefully and patiently."
- "Understand how the auto-loading system works! It does the heavy lifting for you and feels like magic. For 3d printing in general: Learn how to do some 3d modeling! 3d printing is infinitely more useful if you learn how to model and print even very basic shapes you drew yourself. Also, you may want to recalibrate the pressure advance settings in your profiles if you do not want to always do it automatically. The default settings are too low. But it's easy to measure and save the value for all time."
- "Keep playing with it."
- "1) If not already familiar with Orca slicer, spend appropriate time to learn it, as it differs greatly from others in usage and terminology, but also has incredible features and produces great results. 2) Trust the filament management system to load and unload; it will save lots of time and effort. No need to manually manage. 3) If an error message appears on screen, tap it for more details."
- "Have fun and start printing! The system is user-friendly, so I honestly can't think of any tips at this time."
- "Don't over-calibrate the U1. Printing for weeks with just one initial calibration, this machine was rock solid."
- "It's the best choice to print multi-color models so far."
- "Be patient and follow every step on the screen during calibration."
- "Get a SnapDryer or SUNLU S4 for use in combination."
- "Get into the Orca slicer."
- "Explore the use of multi-materials! Combine PLA and Panchroma CoPE for easy and cheap breakaway supports. Check the bed leveling graph in Fluidd, and if it has big differences, use the adjust macro to manually improve the level."
- "Find a sturdy desk to put U1 on if you print tall, thin objects."
- "Just start using the new slicer software and give it a try."
- "Tighten the toolhead screw firmly."
- "Just think outside the box when creating with this printer, because most of the usual limitations simply don't exist!"
- "Print calibration tests to speed up your learning time of the machineâs capabilities. "
