1.9.4 Public Official

This is the public official release of Bambu Studio v1.9.4.

Improvement

1. Improve the quality of 100 overhang

a. Add speed transitions between the overhang and non-overhang areas to improve cooling effectiveness.

Adjusting the smooth coefficient can control the length of the speed transition zone to improve the print quality overhang areas.

After adding the speed transition zone and keeping the speed constant in the fully suspended area, the printing time for the X1C version increased from 4 hours and 14 minutes to 4 hours and 19 minutes. Overhang areas can be printed well. The left side shows the original version, and the right side shows the optimized version.

b. Differentiate between bridge walls and 100% overhang non-bridging walls, and use different printing speeds to improve the print quality of 100% overhang non-bridging walls.

The left image shows the original version where the bridge speed is used for A1 100% overhang non-bridging walls, while the right image shows the improved version where the speed set for non-bridging walls is used for 100% overhang non-bridging walls.

With improvements in both A and B aspects, the printing time for A1 increased from 4 hours and 47 minutes to 5 hours and 4 minutes. This resulted in good print quality.
On the left is the print result before optimization, and on the right is the print result after optimization.

2. Some translations improvement.

3. Add more QIDI profiles, by @HYzd766

Bugfix

1. Fixed the issue where the material list occasionally failed to display on the Setup Wizard page.

2. Fixed the issue that the 0.2mm nozzle extrusion calibration time is too long.

3. Fix the issue of using wall speed incorrectly for overhangs when the support distance is set to 0 in arachne mode.

4. The maximum volumetric flow rate limit for materials does not affect the speed limit for the skirt edge support.
5. Fixed the issue where the Studio would crash when the material cleaning tower rotated for the second time.
6. Fixed the issue where changing the tree brim width does not take effect with organic tree supports.#4487 #4066
7. When height modifiers are used, do not use organic tree supports. #4313
8. Tree supports no longer break long bridges. #4318
9. The Fuzzy Skin option now uses true randomness to prevent the appearance of patterned textures on the surface.
   #4253, @SeaRyanC
10. Fixed the issue where the "Add Preset" function would cause a crash.#4320
11. The results in the PA calibration management interface are now sorted in alphabetical order.#4029
12. Fixed some compiling issues, @penguineer @LightTreasure
13. Fixed some text typo, @t3chguy
