Flow Calibration Tool by CK - Fix Fused Joints On Flexi Prints

Print our latest tool designed to calibrate different filaments to work with lower tolerance, poseable Flexi models. This tool should work with any filament and printer combination. While it is designed specifically for our models it is made to be as accurate as possible for general printing.

If your Flexi models are fusing together, feel too loose, or it seems like small gaps are being fused, you likely need to adjust your Flow Rate for your filament. 

Every filament prints differently, so we highly recommend doing tests before printing any larger objects or time consuming multi-color prints.

This number is usually set between 0.95-1.00 (0.80-1.15 at most). 

Print this small tester before your first adjustment and reprint for every adjustment after. After your first test print, follow the guide below and make adjustments of plus or minus 0.05-0.10 depending on if it’s too tight or too loose. Afterwards, you can fine-tune with increments of +/- 0.01 if you feel it’s needed. 

If the #1 slider is fused while #2 & #3 move freely (or after easily breaking them free) and the test joint bends, your settings should be about perfect. 

While Flow Calibration is the most common reason for fused joints, things like temperature, scale, design, etc., can also cause a print to fuse. Be sure to check your layers in the slicer for any printing paths that fuse joints due to a small scale.

There are more accurate Flow Rate tools that can be found online, but they require calipers and a bit of math. We like this one as an alternative: 3dprintbeginner.com/flow-rate-calibration

Our Flexi Spooders (ehem, Spiders) can be found here:

Settings:

We recommend using the same settings you would use for you models.

If you are just testing in general, 0.2 mm layers with 3 walls would be a great starting point.

*If you plan on scaling down one of our Flexi Spiders or similar, you should also scale down the tester the same amount to be extra safe.

Please let us know if you have any issues or ideas for improvement on this setup!
