- This is a 3D printed mechanical(geared) press.
PCBWay your best 3D Printing & CNC service: www.pcbway.com/
This is a mechanical(geared) press. You know presses are usually hydraulic. But why don't i build mechanical press with a 3d printed gears.
I don't know 3d printing gears are may not enough strong for press and it may break but i would like to see it anyway.

Instead of printing 100% infill you could increase the numbers of perimeters, this will make the gear a lot stronger while not wasting material and print time on the parts where you don't need all that material.
99% infill, on gyroid or something similar that uses x and y motion, is actually stronger than 100% infill. 100% defaults as filling the spaces with walls, which all share a common weak axis. however, using gyroid or other infill pattern, they face perpendicular to the axis of which the wall is printed, therefore increasing strength/rigidity perpendicular to the wall, as compared to printing at 100%.
Indeed, 30% infill and 3mm walls should be really sturdy.
CNC kitchen actually ran tests that prove more perimeters and thicker perimeters are sturdier than infill
Also higher layer squish or layer depth to previous layer increases strength

Those gears definitely were going to deform at the axle. It would probably be wise, while you are CNCing, to also make some steel "hubs" that bolt into the final stage gears at a higher radius and transfer the torque there where the forces are much lower, and then the hubs can take the forces on the axle instead of the plastic gears.
that's genius!
Or at the very least a crosspin through the shaft and into the gear..

You should use bearings. You only see low friction under no load. That's what bearings are for, low friction under load
They still aren’t really needed in this project, the gears that don’t have bearings won’t have all that high load on them and if they do, then they are at low speed, the final gears that mesh with the rack have bearings on the ends of the shafts and they are the highest load gears. There also weren’t any problems related to not having bearing on the other shafts, so why add them if they aren’t needed?

So, a tip on wiring DC motors:
Wiring them in series splits your voltage, and amperage. You can actually wire them in parallel, just flip the polarity. DC motors usually aren't polarized. Parallel allows you to keep the power up and resistance low, resulting in more current capacity.
Series splits amperage, parallel splits voltage.

i think having something to synchronise the two motors (belt or anything else) can also help a lot because those motors are not realy precise and so they can rotate at slightly diferent speed and the press don't push horizontaly (like at 11:25), i think it's reason why your green guide broke (plus the fact that the objects are not flat).

Got my subscription. I love 3d printing and can't wait to do some along with fabrication
Amazing job!!! In your design you unload the stress of the pressing action on gears. If you look at a screw press version you notice that with that design the gears turn only and the stress is adsorbed by frame
the amount of work that goes into your videos.... amazing

Nice video and project explained in the right pace and no nonsense 👍🏻
Only thing I would recommend is 2 guide rails and 4 bushings from McMaster carr. Could extend the base and top plates to accept the bushings. Would eliminate any misalignment and flexing on the frame.
Loved this. Would like to see a second gen, with:
Solution to keep the press straight
Reinforcement of the gears
More power
wow i love how you did all the math on everything, dont see many channels do that, very impressive, i design things but never do the math that stuff is way over my head and just new, im only educated up to trig level so nothing to crazy high
Man, it won't be long before your channel blows up! I am certain. This is really quality content!
You use the simulation on Fusion 360, and it would be great to see some more beginner lessons on how to use the F360 simulation for 3D printing. Also, it would be great to have some more detailed videos on the calculations you use and how we can implement them in our own projects!
Thanks for the great vids - you got a new sub!
Thanks a lot! You actually gave a good idea and may be i can mention about the calculations roughly through the end of the videos anymore.

Fantastically-made mechanical press! Great work as usual...
I really like the fact that you started implementing a bit of voice-overs ;) Your videos have become more profesional!
Glad to hear that Max, Thanks a lot:)
@@retsetman9698 Always, bud! 😎
You need to add walls to the side of the press that it can ride against so the press face doesn't skew
Hey, nice job on the animations. Those really help.
Great job using the graphics dude, really enjoyed it.
Hocam eline sağlık, güzel işler çıkarıyorsun. 👍👍
Add a belt between the two engines on the output of them so they go in sync on eatch side so the press doesnt tilt from side to side when you squish something
Really cool project! I'm currently drafting plans for a project to test out sensors that'll be stepped on, torturing them in various ways to see what will make them fail sooner. Not sure how much I can get away with 3D printing, but I'll definitely be trying to do as much as I can. Might just end up basing my design off of some of what you've shown here :)
💪🏿😅

it would be really cool to see a part two to this with all of the 3d printed parts printed in metal instead, if i remember correctly pcb way offers that now too
I calculated this back in the University many years ago. It’s two main forces that are under pressure. 1 is the axels, the other is the teeth surface on the gears. You can easily solve both with widen the gears, so that the surface area increases. In short make the gears wider. Then off course you can calculate pressure based on the ratios. You can in principle achieve hydraulic pressure with gears, but the “power density” of hydraulics is hard to compete with.
Geared rollers - or just rubber rollers / cams
This is the way. Everyone trying to say oh use X filament or Y filament and this or that but those are only marginal improvements at best versus designing this to work with 3d printing constraints.
Beautiful work. 👏👏👏👏
Using straight cut gears may give more torque due to the thicker teeth and surface area of contact between the gears but it will become noticeably louder. One of the other comments 6 months ago suggested PLA+ like in firearms. PLA+ is good for handling the shock from said device and not a gradual load. I have no suggestions on material though so go for it. Also I think the Algorithm sent me?
It is time for MGN H linear guides and get PCBWay to CNC the gears from metal.
I've been thinking about doing this for a while myself but didn't know where to start. Mine probably wouldn't be with v-slot or 2020 rails, though XD Those are still a bit outside my budget ATM thanks to unforeseen events.
I think you would get a lot more performance out of this if you redesigned the frame gantry to eliminate that rather significant canting to either side as it's coming down. It was more than 30° out of alignment at some points in the demonstration. That adds a LOT of resistance into the system, regardless of herringbone gears.
Problem is with these DC motors there is nothing to synchronise them. Depending on differences in friction and load it will always drift.
I'm thinking of using a belt to drive and synchronise a while bunch of m4 threaded rods, like maybe a dozen of them. They would provide both the bulk of reduction and the force would be distributed.
Cheap construction? Just square box alu section, you can braze them together or use angles and plates to connect them.
@@SianaGearz I wonder if adding a clutch mechanism to the out put of each would help. Kind of like the slip type of clutch where it has play to slip forward but not backward (no idea what that's call, just seen it in a lot of random gadgets).
@@eideticex I can't see that it necessarily would? Depending on friction and the like the forward speed of DC motors is different, even unloaded two "identical" motors off the same batch could differ by several percent due to low precision construction. Back slippage isn't really the issue here.
If you were to implement a clutch like mechanism it better detect which of the motors is too far forward and apply extra friction to that. I do think this is possible but i don't have anything in mind.
this just popped up on my recommended. Instant sub!
Glad to hear that, thanks a lot 👍
Creative video, thanks for sharing it :)
You should set a second limit switch on the downward travel, on a sliding bracket that will allow you to quickly adjust how far it smashes into things, and so if it accidentally fires off it won't strip its gears at the bottom of travel.
Best practices dude, always follow em if you can and it won't do you wrong.
You may consider adding current limiter to motors, and pressure sensor to main table
I think you should design the next one with some lever action, so the 3d printed parts aren't taking the brunt of the torque. For example if you had a scissor jack and made one of the arm halves on each side much longer past the fulcrum, you can get a very long lever that still preserves some kind of parallel motion.
lever+ screw
Where did you learn how to figure this out? The way you modeled it, had it in excel doing the math for you, and even had a program showing stress points, is amazing to me. Any way you can point me in a direction for resources?
Awesome video. 9:12 , you basically made a gravity powered DC generator, well, for a very short duration haha. I wonder if you hooked up an AC motor and basically pulled/pushed the press up and down if it would output an AC signal.
the fact that you use blender makes me respect you infinitely more
Profesyonelce hazırlanmış ve çok fazla emek içeren bir çalışma olmuş. Animasyonlar ve analizler muhteşem.👏👏👏👍
Çok teşekkürler 👍
Türk olma ihtimalin var mı diye yorum atarken cevabımı aldım. Eline sağlık
@@arsimert Ben de :)
With this design the force produced by the press is limited to the sheer strength of a single tooth on the pinion gear/rack multiplied by the number of pinions/racks on the final stage. So one way to increase the force produced before failure would be to increase the size of the gear tooth, or to increase the number of racks on the piston.
Cool design!
Thanks man!
Is it true that mechanical press is better than hydraulic if you don't mind about speed very much? for example cold welding two thin aluminium sheets together would require the mechanical press to move only slightly and so speed not so important because only a small distance to move. I would make one for cold welding stainless steel sheets and build up structure by adding layers that have been cut with lasers. Like a 3d printer but with cold welding and I could use supportive structure cut into the steets for difficult shapes which would later be removed. I think mechanical is better for that than hydraulic but what do you think?
Bravo pour votre partage 👍
A $30 car jack will produce 5 tons of force. I think you would have been much more successful adding gears, a frame and a motor to a car jack and with 2 jacks could easily have 10 tons of crushing force.
I love the danger tape
did you make the square bar perfectly round with just a file?? w0w
On the surface that crushes your items. Would it help putting those arms in tracks so they bare down evenly and not apply uneven stress to the gears? I hope that question makes sense
A very interesting idea🤔
Idk if it is practical for anything but it is a neat project.
I can imagine that teddy bear saying "why you bully me" 🤣🤣🤣
Did my comment just not post? Anyway,
Can you share how you made those gears and linear parts so they fit together? This is exactly what I need for a project of mine
Love this. What is the name of the aluminum extrusion you used?
80/20 you can get them in imperial or metric, just about anything you'd want, they have.
Next up on the hydraulic press channel we crush a punny plastic imposter 😂
Serious note.. Fun build looks like a great toy and bet you learned a ton along the way
I have never heard of PCBway doing CNC stuff before. Crazy because I've heard many people advertise their pcb stuff.
They also do metal 3d printing which is cool. They actually have *hella* services it’s impressive

Crushing nuts and cans is not what hydraulic presses are usually used for) Do you have actual forces of the resulting press?
Is it possible to make a mini 3d printed can & plastics shredder, using those gear ratios?
I think it would be stronger to use a cable for the pulldown force instead of the linear gear
I will say, that steel plate did not need to be CNC machined. With just a center punch, careful measurements, a saw, and a regular power drill you could have very easily made that yourself from 1'x1' sheet steel.
Can you share the software you use to simulate the distortion?
What are the slotted rods everyone is using for building 3d stuff I wanna find where to get some
Edit:( I mean those metal extrusions with the slots
Great video!
Thank’s a lot.
Think if you did block and pully system instead, would you get more power? You would have to spring load the press to return to neutral. Just a thought.
Whats the software you use to makes the mechanical animations?
Bro is just drawing on his wall with a pencil 😂 love that
i think that connetting gears to axels by splines instead of squared angles can improve gears life
4:22 A moment of silence for all those suzanne who give their lives for the simulation of science and technology
Awesome cool

Can you use stepper motors instead of DC motors please and thank you.
I thin star like metal rod (not square) at least for cogs joints, and larger/wider cogwheel with teeths with 100% infill all from ASA it would hold up to 200KG or maybe more.
GREAT MAN!!! this is really useful experiment! you are a pather. why didn´t you use just straight teeth and not that like V?
There are mathematical calculations at 5:14
Is there a website to learn how to do these calculations please?
would a piece of threaded rod not be better to apply the force?
I definitely like the idea of the video but long drawn out technical explanations is tough to sit through for anyone that's not seriously interested in learning. There's a channel on youtube that does these kinds of experiments but with lego and they do the videos without talking at all and it holds my interest through the whole thing.
you could buy metal gears like aluminium ones they dont break easily but slightly costlier
Can you get Torx shafts?
What if I make molds of the gears and cast them out of a metal alloy
5:00 I wondered why you didnt use a higher module for these gears already
PCB WAY c'est génial combien coûte par exemple votre plaque sur mesure ? Merci
Why did you use 3D printed T nuts instead of just normal metal ones?
Also the press seems a little flimsy, it might be better if you strengthened the frame and added some linear rails or something. With all the flexing of the press bit I’d be surprised if the plastic rail at the back is still intact.
I would also be surprised if you were actually getting 2000 N out of it, it seemed to struggle quite a bit with crushing things, like the can.
can you use this to make cold press juice?
13:00 i was hoping the bottle cap would go shooting lol
maybe consider using a different wire colour for your motor power supply, otherwise great video
Screw bests rack and pinion by a wide margin. Simpler to build, too!
Make the intermediate gears from PETG
Stronger layer adhesion
One method Iv seen is add weight to the crushing plate. Say the gears can lift 50kg then add 49 that’s an extra 49 kg crushing power with no more stress on anything :)
totally thought you meant some kind of printing press at first although I feel that would have been somehow more ironic
I believe you should put something to sync both motors.
Bin Voila un parfait compacteur de canette ! Réellement
Why not use a torque limiter to keep your gears from breaking?
Now I see why there is no video for three months.
Thanks a lot my friend👍
Sir what is the diameter of each gears
Pls use metal gears. Will u use ?
Might pay to have side guides for the lowering plate to stop side play
i'he been thinking for doing this
Do some FEA and acetone the parts so they are smooth on the outside.
It's quick for all that gear reduction
So... this was a cool video. So, if I were to scale this up, I could do some cool shit.
Like, before you broke it. You might have been able to make an adobe brick with that little compressing machine.
Scaled up, made of steel... you could press Hempwood with it. Or Bamboo stands into Baboo plank or pillar or whatever.
Like, seriously... this was a good... simulation.
Suppose you were in Madagascar, and the best technology is a car. I suppose, there might be a way to set two car engines on either side.
What if you wanted a hand cranked press. Like... low tech. Wouldn't you want some worm drive setup at the bottom output? That way the design works as it currently does, but it retains tension. I suppose the worm drive would be the hand crank.
I suppose if you wanted a hand cranked one... you'd need a third gear set... so... the gear sets would be covering 3/4ths of the faces to the press machine... and the whole machine could be made of hempcrete. So it could begin getting constructed within 150 days (the time it takes for a harvest of hemp).
Lol. With a third gearset... wouldn't you have more torque. (Is that the term?) More power with less stress on the gears?
Anyhow... if it was a manually cranked press... it would be less stress on the guy cranking it too.
That guy cranking it would need one BIG wheel to crank it... I think. Lol. Leverage is your friend, especially when it comes to compressing materials, to make a DIFFERENT material.
Like compressing hemp fibers and glue. PAPOW! Hardest wood on earth. Right there. With the machinery that an ingenuitive cave man could invent and make, with ease.
He'd need to know a bit about Botany. But Hemp's not a picky plant.
He'd get a shit load of cool shit from that plant. But Hempcrete is just hemp fibers, water, and lime. You compact it into any form. Wait to dry. It's harder than concrete with no steel reinforcement.
He could make pottery forms of everything. Cast the hempcrete. Assemble it (because Hemp isn't heavy). Lol...
I'm no one to ask... but... could you... make that video? I just subscribed. :)

You limited the force of press to force which can withstand the tooth of gear. Which tooth and which gear would be an interesting math activities.
It would be a better to use the simple leaver.
i 3d pinted an automatic orange press.. but just skipped the part with the gears and used the motor of an 800kg electric hoist lift :)
Try increasing the gear ratio it might make it stronger but you will probably need stronger gears
I have a lathe with herringbone gears. You didn't see them much until 3d printers due to cost.
no escribo en ingles, pero tratare de explicarme lo mas fácil posible, lo que yo aria en el diseño de los engranajes, seria hacerle unos agujeros que lo pasen de lado a lado para poner unos tornillos roscados o clavos para darle mas resistencia a la pieza, de esa manera no trabajara tanto sobre las capas
I do not write in English, but I will try to explain myself as easily as possible, what I would do in the design of the gears, would be to make some holes that pass from side to side to put some threaded screws or nails to give more resistance to the piece , that way you won't work so much on the layers
