As part of my "Master Profile Playlist", this "Universal Flex" profile was designed to solve the two biggest headaches with TPU: clogs and surface vibration marks (VFA). After extensive testing with various Shore hardness levels (from soft 85A to rigid 65D) on bed-slinger printers like the A1, I’ve fine-tuned the speeds and accelerations to ensure stable, "injection-mold" quality results. This profile focuses on aesthetic perfection without sacrificing functional strength.

⚠️ THE GOLDEN RULE FOR TPU SUCCESS

TPU is extremely hygroscopic. Even if your roll is brand new and vacuum-sealed, it MUST be dried before use for professional results.

• Dry your filament at 70°C for at least 12 hours before printing.
• Keep it in a hermetic dry box or heated AMS during the print.
• Printing wet TPU will cause bubbles, poor surface finish, and extreme stringing.

KEEP YOUR FILAMENT DRY!

Technical Highlights

• Anti-VFA Finish: Specifically reduced outer wall speed (25mm/s) and acceleration (1000mm/s²) to eliminate mechanical vibration marks common on the A1.
• Clog Prevention: Strictly limited Max Volumetric Speed to prevent filament buckling in the extruder gears.
• Optimized Retraction: Fine-tuned (0.4mm Length / 30mm/s Speed) and Zero Z-Hop to minimize "spider webs" between parts.
• Tested Brands: Successfully validated with Bambu, Elegoo, Overture, and Sunlu TPU.

How to use

1. Download the .3mf file and open it in Bambu Studio.
2. Import Geometry Only: Delete the sample model, import your STL, and select "Import Geometry Only" to keep these custom settings.
3. Pro Tip: For very soft grades (85A or lower), using the external spool holder is highly recommended to reduce friction.

作为我的“大师配置系列”的一部分，这个“全能柔性”配置文件旨在解决 TPU 打印的两大难题：堵塞和表面震纹 (VFA)。

在 A1 等床式打印机上测试了不同硬度（从 85A 到 65D）后，我微调了速度和加速度，以确保稳定、如注塑般的高质量打印效果。此配置在不牺牲功能强度的前提下，追求极致的表面美感。

⚠️ TPU 成功的黄金法则

TPU 极易吸潮。即使是新买的耗材，也必须在使用前进行烘干。

• 在 70°C 下烘干 12 小时以上。
• 打印过程中请将其保存在干燥盒或加热的 AMS 中。
• 打印潮湿的 TPU 会导致气泡、表面粗糙和严重的拉丝。

务必保持耗材干燥！

技术亮点

• 防震纹表面： 专门降低了外壁速度 (25mm/s) 和加速度 (500mm/s²)，以消除 A1 等打印机上常见的机械震纹。
• 预防堵塞： 严格限制最大体积流量，防止柔性耗材在挤出机齿轮内折弯。
• 优化回抽： 精细调整回抽（0.4mm 长度 / 30mm/s 速度）并采用 零 Z 轴抬升，最大限度减少零件间的细微拉丝。
• 已测品牌： 已在 Bambu, Elegoo, Overture 和 Sunlu TPU 上成功验证。

如何使用

1. 下载 .3mf 文件并在 Bambu Studio 中打开。
2. 仅导入几何体： 删除示例模型，导入您的 STL 文件，并选择“仅导入几何体”以保留这些自定义设置。
3. 专业提示： 对于极软的材料（85A 或更低），强烈建议使用外部料盘架以减少摩擦。
