3D Printed WORM GEAR - Can u Really Use Them? (PLA vs PETG vs ABS)

Can u really use 3D printed worm gears or they self-destruct themselves? In this video, we run dry and lubricated tests at low, medium, and high speed. We test most common 3D printing materials such as PLA, ABS and, PETG. I use only high-quality filaments.

Interesting video however as worm gears are typically used in low speed high torque applications I think it will be even more interesting to see how they perform under load

[doopfdeckel]

No lube, no load. Do a longterm test with low rpm and high torque. That would be interresting :)

I'm using printed worm wheel from PETG for car front wipers for 2, 5 years. Still working.

worm gears are usually applied in low speed high torque applications. For testing worm gears, different load cases at low speed would be more interesting then just testing operating speeds.

Normally on a worm drive, the worm wheel and worm gear are made from different materials of different hardness. The worm gear is typically made out of steel and the worm wheel is typically made of brass. Also, input speed on worm drives typically does not exceed 3600 rpm.

Use igus filament for parts that are subject to wear and friction, they are optimized for low friction and contain solid lubricants!

I made a small 3D printed transmission, without grease I could never get it to run for more than a minute or two. I greased it up and have had zero issues since. 3 months now on the same transmission on an RC car

that really blows my mind how huge of a difference a little grease made!! awesome video. be great to see how well they work under a high load!

[BagheeraTube]

Run them for a week and see which breaks first. Having them survive less then one hour doesn't say much of how useful it would be in a real world application. Especially without any load.

Need to test low rpm with higher torque applications like worm gears are usually used for.

I've seen many different 3d printing channels, but no channel did exactly what I wanted in terms of practical engineering + 3d printing materials and tests. Your channel fit that criteria flawlessly, and very well! Thank you for your content; subscribed, and I hope your content continues to flourish.

I've had great success using a worm drive printed in very high quality PLA (to avoid surface inconsistency, usually I don't care on functional parts) with the same white lithium grease I use on my printer's Z screws. While I see a lot of comments demanding to know how they fare after hours of run-time, it's worth noting that plenty of projects require low RPM in short bursts, such as a pet feeder or automatic blinds. Also, the awkward way I had to design them in OnShape actually allowed me to change the tooth profile such that it could be printed upright with no supports!

[idiotickidful]

The lubricant made such a huge difference!

[unusualfabrication]

it's amazing how much the grease increased perforamance

[nikolaus]

Worm gears are not meant to perform in high RPM, but in high torque applications, so 8000 or 12k RPM is much to high

[nccyr]

Thank you for making this test, this is very useful information.
I was going to order metal gear set but now I feel confident I can print them myself and use them for my low speed purpose.

One only needs to look at industrial applications of this type gear reduction system to see that nearly all use a maximum input speed of 1800 RPM. The worm is almost always made of hardened steel while the wheel is made of brass. The worm is usually mounted over top of the wheel. The wheel runs in a heavy weight lube (usually 90W) at a level that's about one third the diameter of the wheel, i.e. just below bottom-dead-center of the wheel's bore. This level virtually eliminates leaks while ensuring contstant lubrication. The heavy weight lubricant is required due to the extreme pressures encountered at the tooth interface between worm and wheel. By the way, this gearing system is considered the least efficient of any gearing system.

Great video! This is telling me that for intermittent, low speed use, properly lubricated 3d printed worm gears could last a long time. Such as for remote camera pan/tilt, or even in simple robotics. Suggestion - put an affiliate link in for the grease you're using. Some grease isn't safe for plastic and will dissolve it.

one Tip...
Print Gears and screws in 0.15 layer height.... it would be very better.

[dagg]

Not only are wormgears used in slow rpm situations, they also actually lock the compononet gearbox. A It can only rotate one way, or actually it depends on the slope angle of the cog and wormgear..
