When you print with PETG, be sure to increase the infill. Using different infill patterns will also yield better results too.

@3DRC-707 3 года назад

Yes absolutely.

@Iron_Lion_Of_Zion 3 года назад

Also, if u use matrix combining, pre infill stage, u will see 45-50% increase in strength, with approx 15.5 & 17.78% less material used, which on bigger prints all adds up.

@msworkshop522 2 года назад

Yes, until 40 % there are benefits. Also maximizing the wall lines will give its maximum strength, example with most common settings for every 1 cm2 of item use a setting about 12 wall lines. Also run the hot-end hotter than usual to achieve better bonding. Good video I enjoyed it.

@martylawson1638 3 года назад

Nice gearbox! Needs an output stage with output bearings and a overload clutch. (maybe some mounting holes too?) The output bearings are to support overhanging loads, and the overload clutch will make the gear-box bomb proof by slipping before anything breaks. I've made overload clutches both with spring loaded friction clutches and detent mechanisms.

This is really fantastic work. I think it is sincerely admirable that you made the files to print this free to download. A true maker.

@josephshubin8465 3 года назад

An awesome video like always. Printing the sun gear perpendicular to the force direction will greatly increase strength. What I mean is print the sun gear in two parts (length-wise, perpendicular to the gear teeth). The plastic is failing due to the torsional force being in the same direction as the print layers. The parts will be a lot stronger.

You... You made a functional modular planetary gearbox?? That's incredible! Really, well done! I can't wait to see what you use it in next :D

@MrV1NC3N7V3G4 3 года назад

Ok bro, you got me. Liked and subscribed with notifications plus a little engagement here for the algorithm. You're very talented. Not only in mechanical engineering, but you're a master of 3D printing! People who haven't 3D printed before just think you click print and out comes a perfect object. They don't understand bed leveling, offsets, rafts, infill, elephant foot, supports, overhang, bed and nozzle temperature, nozzle cooling, extrusion size and feed rates, etc, etc...there is so much that goes into getting a perfect print and you make that part look easy.

@peterciurea7771 3 года назад

I can't wait to see this channel once metal 3d printing becomes affordable to you. All of a sudden, what previously would be considered toys would become real alternatives to commercial parts and assemblies. Make sure to save every design. With even minimal automation, I can see how this might turn into a business - selling assemblies that now are durable enough to use for hobbyists and eventually professionals.

These parts could be cast quite easily already! He just has to make a mold from the plastic parts!

He made the designs, it's easy to send them to a CNC to be cut out instead of additive manufacturing

@mozkitolife5437 3 года назад

Very clever. Great work. You should know by now by intuition that those load-bearing parts require much more than 20% infill.

@tomsmith3045 2 года назад

@pietrom2642 3 года назад

i think that a nice idea would be to print with increasing stage thickness, so the gears are thicker when more torque is needed and thinner when they spin faster to reduce drag and gearbox size, if i will prints these i think i will try, being in need of pretty high reductions

Gearboxes usually look like disasters of incomprehensible moving parts, but this is a very smart way of keeping this all tidy!

@kamil4151 3 года назад

Fascinating, your prints were almost hollow in the first round and yet still managed to pull up 20kg. If they manage to make the plastic bond as strong as injection molding, this would be a great way of saving lots of materials.

@Justin-vj2rk 3 года назад

You should print the gears as separate pieces then the shaft (click together after print). If you do this you can print the shaft with the layers along the length and it will be much stronger to shear forces.

you should look into helical gears. would make this much more stable and reduce friction, since the gears are self retaining.

You could get one of those torque adapters and print something to adapt into that. You could see exactly how much torsional force you can apply with it with each gear set

@aa-ej5jq 3 года назад

Great 👌👌👌. I am giving you an idea to use this gearbox. Use weight to generate electricity . This should use any heavy object lifted to an elevation. The project should devise a mechanism to control its descent at uniform speed. 😊

@lohikarhu734 3 года назад

To push in the bearings, if you need to "hammer", use a piece of pipe, or a socket of the same diameter as the outer bearing race...you can use something like "water pump pliers", in place of a vise, again with a little piece of pipe, or a spare bearing, to push the bearing into the gear.

@RandomGuy-rj9oq 3 года назад

Holy shit stuff like this is incredible. I had to subscribe. Its strange your instagram doesnt have more traction. Just keep this up and youll start growing very fast hopefully. I really like the style of your videos, its educational, enjoyable and very satisfying to watch.

@putteslaintxtbks5166 2 года назад

If this were made with herringbone, I think to load them in you would need the case to open from side instead of from the front, but all the gears would stay better in there place. There is something about planetary gears that always kicks me into nerd gear.

@ted_van_loon 2 года назад

you should try to make a automatic or manual planetary gear box. planetairy gearboxes are often used in things like cars and drills due to the simplicity or making it shift gear ratio. doing that would allow you to always use the exact same gearbox, you only need to set it to a gear, or you can set it while running electronically which allows for a better speed to torc/acceleration ratio.

@electronic7979 3 года назад

@negril_rasta 3 года назад

This could make an awesome generator. Hand Crank maybe

@bjornwiegel5220 3 года назад

Nice gearbox but why didn't you use a design where you could access the bearings inner ring from both sides? In this way you could have tightened up the mounting screws in the planet gear carrier more decent and without paying too much attention to the mounting torque. This would also make your design more robust and lead to a more precise movement of the planet gears...

@Sim3Dfly 3 года назад

I think about the same. My gears also melted because of friction on one side.

@YasinKAYA-do4ek 10 месяцев назад

When i see planetary gear, i give a like.

@peterciurea7771 3 года назад

Try making some strain wave(harmonic) drives as well as some cycloidal - see if they are more forgiving of the material. There is a type of strain wave drive in which you can use a ready made rubber timing belt, the type usually used with steppers, as the flexible gear.

@hasuo9749 2 года назад

for an 150w DC motor this gearbox did pretty well.. i must say that the problem while gearing this to a certain number will the the stupidly slow speed of spining.

@maverickstclare3756 3 года назад

good idea but why not 100% infill for the "coupler"?

@LetsPrintYT 3 года назад

100% infill is a good idea and this coupler should be redesigned. I was a bit rush at the end. XD

@Sondalive 2 года назад

"Be sure to grease everything up" proceeds to only grease first stage and put all the other gears in dry... :D

@corisco8817 3 года назад

The first test (10kg, 35cm) was way, way harder on the gears and motor than any other test that followed in the video. That first one was 3.5 kg*m, while that last, 40 kg test was only some 1.2 kg*m (assuming a 3cm radius winding - it was probably less than that).

@averitiamiku Месяц назад

I made an gear ratio with my lego technic, i used an calculator app and it said it had 880 newton centimeters of torque, it was hella slow but i could barely stop it using a beam, releasing the beam would instantly whip it 1/4 of the rotation forward and lets say it was so strong it ripped apart a small gear

@TheWoodWorkingPilot Год назад

Super cool! Which grease are you using on it for lubrication (the blue stuff)?

@666DarkOverlord 3 года назад

I'm wondering what kind of speed you can get if you run this gear box with the input running the other way using the 8 motor gearbox as the input, would be interesting to see the kind of speed and force it can generate with a fan or pump connected as the output of those 2 projects tied into each other, plus material testing for extremes of speed rather than torque.

@acorgiwithacrown467 3 года назад

Your tolerances might need to be a bit tighter or that little wobble will get exponentially worse with each stage but this is a really cool design nonetheless.

@c3N3q 2 года назад

This is really cool, the concept of stackable modules.. 👍 I'm wondering if you can measure how much the power/torque increases with each module added, and if the increments are linear.. 👀 I think 3d printed gears might actually be useful even for heavier applications, if the end parts that carry the load are made of metal... Great job! Also, have you tried to print with what they call "black aluminium"? It is nylon/carbon mix... not sure of the brand name (s). Good luck with your projects!

@niclasnordqvist 2 года назад

Great gearbox! I printed with PLA and the sound is deafening when it starts spinning though.

@cripplingdepression8889 2 года назад

So technically with some optimizations in infill, reinforcements and material this 3D printed gearbox is capable of 30Nm with an ordinary drill motor This is huge!
