My first NinjaFlex print...almost.

My first NinjaFlex print…almost. Does anyone else’s experience with NinjaFlex show issues with overhangs more than usual? The top of the owl and the bottom of the wings sag.

Normally, I’d attribute this to under extrusion. This owl has the multiplier set in slic3r to 1.04 with 3 perimeters, no infill and 210C print temp. I notice my walls on a 20mm cube are ~19.9 so maybe I am under extruding still.

It’s great print compared to what I achieved. I have an issue with even the slightest angle. Once I print not fully vertical wall it starts to warp. Did you experience this? If so how did you solve it?

Printing slowly is by far the most important thing, 30/mm per second universally. Where did the part warp, on the platform or mid-way through the print? I had no warping issues with the platform. Did you print a cube then measure it or a single perimeter loop to see if you were getting consistent extrusion?

I had no problems with warpage near the build plate. If I would print your owl I would say it would warp badly when printing the eye. I did not do the measurement, however if I print a vertical part it looks fine. What temperatures did you use? Closed chamber or extra cooling?

I was able to get consistent prints at 20mm/s. I did not completely get rid of the over hang or strings between perimeters. I was extruding around 210. 220 and up the ninjaflex was too fluid. My bed temp was 60. Using 3mm filament and 0.35 nozzle with 0.25 layers.

I had much better results with stringing from cura. A couple hairs instead of hundreds.

That’s because Cura has smarter toolpathing :slight_smile:
