I tried to find the Strongest Filament Extruder.

I tested 11 different extruders for 3D printers to find out which is the strongest!

What's your favourite, go-to extruder?

[ldomotorsjason]

I really enjoyed the video! Very proud that Orbiter V2 won the battle of "force per weight". And among of 11 extruder, 6 of 11 used LDO stepper motor, which a big win for LDO. Very Excited!

[VezD]

Again an awesome video man. But I dont think we need a lot of pushing force...we need to let the hotend flow and avoid over-pressurizing the heatzone.. or we get crappy quality

[TheNextDecade]

Tiny injection molding is right up my alley! I really appreciate this Stefan!

[properprinting]

Nice to see this comparison done scientifically, very well done! Thanks for including my beefy design!

[Borgedesigns]

Ive been working on a similar idea for a while based on a failed print, which filled my silicone hotend. It created a blob that had a smooth surface finish, 100% infill and sharp features, which lead me to the idea that it was viable. For those saying why, small FDM parts are weak and struggle with small details due to the printing process. While slower than traditional injection moulding there is certainly a place for a small machine like this. Even a 5-10 minute cycle time is still faster than printing and due to the low cost and size many machines could be run at once.

There is also an extruder based on a brushless motor, the filament flows through the centre of the motor, really interesting design. No idea how good it is though.

[MichaelWatersJ]

I love the indexed gear force on my LGX, it makes printing more repeatable. In fact, I'd love to see how the LGX lite compares in this testing.

[bcooley]

I’m impressed with the biqu h2, very light and like the hemera has the hot end built into the very small stepper motor which I believe a 9:1 gear ratio.

[roboman]

The OMGv2 series extruder gave me an idea. Two completely separate extruders, in series. A big beefy one like the Hemera or Proper at the start, then a bowden tube connecting it to a small lightweight extruder like the Orbiter. The big extruder would provide most of the force, while the small extruder would help with retraction, especially with flexible materials.
Both high torque with low print head weight and good retraction performance. It also spreads out the "grip" on the filament, so any grinding will less likely cause an unrecoverable failure.

Something even smaller and lighter could be designed, as the head extruder would really only need to provide a fraction of a KG of force.

We us Dyze Extruders, Nozzles and Hot-Ends on our Blackbelt Printers and they are super reliable. We are printing often big parts which run 3-5 days in average, use PLA, HT, PETG, Varioshore TPU, TPU, nGen, nGen_Flex, etc. and it never skips a beat. One some Dyze Parts we have over 12000 hours of printing and they still work. Really happy with the performance and after the Test here I see even less reason to try something else in the moment. Loved the Video!

[scruffy]

Would love to see more extruders tested. Sherpa mini, clockwork 2 and more.

[marsgizmo]

This is an excellent video!
I'm pretty curious to see your small parts injection moulding project 😎

[msytdc]

It would also be nice to see this testing done with flexible filament for another comparison point between the various models and design features.

[JustKyzuuh]

So happy to see proper printing get a little recognition here. He's been taking on awesome projects for a long time!

[eclsnowman]

Best performance in my tests from years ago was Bondtech QR and Bondtech V2. Planetary steppers with medium diameter gears. Worth a look in the right application. I tested max flows and pressures into a load cell rig in PLA, ABS, PETG, and TPU.

[Galladex]

Where is the Microswiss NG extruder that literally won in the tug of war video you mentioned?

[ManjaroBlack]

I've been running an OMG v2 for some time now in a Bowden setup. It's been reliable and no issues. Glad to see it did well!

[marckerger]

The spikes are cool. Maybe cutting a groove in a normal extruder wheel would also improve bite force.

[Edward-pwzz]

i am REALLY looking forward to your injection molding can you try SLA printed molds with plastics that melt at low temps?
