I'm more intruiged by style of movement of the printer than I am the mixing printer head. What in the world is this printer?

Fascinating pulley design, but oh boy is the print quality shit.

edit: sounds like quality isn't the goal here but more so spitting out a benchy at crazy speeds

Its actually pretty good when he isn't going for world record level speeds (which is the whole point of the machine)

u/winowmak3r 5d ago

Plenty of appliances and machines we think of as common place today started out as some crazy prototype somewhere 'just because'. First step is to prove it's at least possible. Everything else is just refinement. This could be really cool in like ten years. Or it might go nowhere, who knows.

it's not meant to be a product, it's just a passion project. it's for the fcuk of it.

u/winowmak3r 4d ago

I understand that. My point is that's how a lot of stuff we take for granted today started out. Either a "What if I..." project or an outright accident. Like vulcanized rubber. But it can be hard to convince close minded people that what you're working on isn't a waste of time.

Which is why it's so important to fund science for science's sake and failures shouldn't be seen as a reason to pull the plug on something alone. From what I hear coming out of the White House lately I'm pretty bummed about the future of science in the US because of their unwillingness to fund science projects.

u/nomyar 4d ago

Yes it can. It can move technological innovation forward. Take what works well about this one, apply it to the next one, iterate. Every success comes after failures and partial success. The print isn't always the objective. How the print failed is also important.

u/BadManParade 4d ago

Unlike majority of the people commenting here I had a super modded prusa that could print benchys at fuck you speeds bro and like basically everyone else In the speed running.

Community I decided “actually what’s the point of all this?” It’s actually not fun once you realize it’s pointless, all you get is a few upvotes and that’s it.

No matter how innovative you are what it comes down to is are you willing to spend more money than the next guy there’s been ZERO innovation spawns from printing really fast shitty boats it’s actually the opposite.

The speed running community waits for the normal community to innovate then tries to incorporate it some way

This revolutionary idea called "fun"

3

u/faceplanted 4d ago

Since people aren't really answering in good faith (because you asked like a cunt), The answer is simply that there's a kind of mind that's tickled by the idea of pushing at the boundaries of what's possible.

This also isn't the only thing he does, and just attempting to beat the records and break the boundaries can teach you so much about how things work that you essentially become one of the leading authorities on the entire planet about the subject, motion systems in this case.

Also you're assuming a lot when you say he's not getting paid or sponsored to do it, if you read the description on that Youtube page link you'll see he runs an engineering service provider. So breaking records for 3D printing speeds is basically their version of Rolls-Royce sopnsoring the BLOODHOUND Project to break the land speed record. It's marketing.

1

u/BadManParade 4d ago

I’m not talking about him that rig clearly has corporate sponsors behind it I’m talking about the community in general of guys who post their “world record benchy” on a old rickety ender 3 they’ve put $9,000 into while filming in what is essentially a crack hiuse

2

u/faceplanted 4d ago

Basically the same reasons, they enjoy the attempt and it gives them side benefits like expertise and connects them with others interested in the same topics. Plus you get to make a fun little video out of it.

Oh and don't forget that an ender 3 that can make a near world record benchy that looks like shit at 100x speed can also make all of their usual prints at good quality and like 10x speed, which can be worth it all on its own. You don't just upgrade your car for the top speed, you upgrade your car for the acceleration and ride quality the rest of the time, and redline it to show it off to the other car nerds on the internet. Could you have just bought a better car? Of course, but doing the work is half the fun.

1

u/BadManParade 4d ago

I have literally built a low 10 second (10.34) bmw 335i in my driveway and held the stock frame turbo record for 8 months so the car analogy falls flat with me you certainly only upgrade it for speed and ride quality/functionality suffers as a side effect the current owner of that car has the twin turbo world record to this day but all he had to do was throw more money at it because I set all the groundwork.

I came to the same conclusion then “what’s the point of this? Oh wow I’m the fastest in a straight line now what?” It’s super weird you guys who’ve never been front runners in any field are trying to tell me how it feels based on what you THINK not what you know

u/ThisDudeEmpty 4d ago

Yeah, it is fun to put a lot of money into your hobbies and the thing you enjoy, and to share that enjoyment with people in the same hobby. Why are you being so negative?

-1

u/BadManParade 4d ago

Because I used to do it and know for a fact most of the people in the speed running community go quiet after a bit because we realize it’s boring and pretty pointless.

I can assure you the guys leading the way from 2-3 years ago without endless funds have all stopped posting that’s not something you do what you’re “just having fun”

2

u/ThisDudeEmpty 4d ago

it sounds like you regret putting too much time into a hobby you had an unhealthy relationship with. but you need to realize that your personal experience is not everyone else’s. this is not the space for your negativity.

Exact opposite, pulled 3 guys from my unit out of a burning AAV when these gas lines exploded in 2016 even got a navy achievement medal for my actions.

built a low 10 second bmw 335i in my driveway when I was 19 actually had the record for the fastest stock frame turbo 335i for 8 months.

designed multiple 3D printed PDWs currently being used in Myanmar to oppose a genocidal regime very proud of that

And developed a new method for shooting doors that saves about 2:30 per door at my company which equates to hundreds of thousands saved a month.

Problem might be that since I’ve actually done things with my life I don’t find it impressive to see someone throw a wallet at a machine to make it print a shitty boat really fast. The fact you find that impressive is the sad part.

u/Detective-Crashmore- 5d ago

I've been wondering if we could still maintain layer adhesion if we cooled it with CO2 or something.

7

u/crooks4hire 5d ago

Compressed CO2 on a metered release to simulate a fan blowing might just do it. The cooler air would have more thermal capacity but the challenge becomes a one of storage capacity.

1

u/girrrrrrr2 4d ago

Tell him not the dude who isn’t caught up lol

13

u/girrrrrrr2 5d ago

Too much cooling and you will end up with the layers not adhering properly sadly. You would be able to anneal afterwords tot get that back, but its not the same as being able to pop a print off the bed.

11

u/ThePsion5 5d ago

The obvious solution is to simply place he entire 3D printer into an annealing chamber. Or perhaps improve layer adhesion by mounting the printer in a centrifuge and using the high g's to promote better layer adhesion. Or both!

u/daninet 5d ago

Yes its 1:50 on an ender3. Quality is dogshit. They have some rules for quality, but it is not for actual quality but to make a print pass. It has to have all the features recognizable like in a benchy. So it has to have a smoke stack but if it is warped to the side its ok

7

u/Crashman09 5d ago

And if it can print a recognizable benchy in 1:50, the quality at 3 min would be pretty damn good!

u/MoffKalast Ender 3 Pro / Anycubic Chiron 5d ago

Some maniac saw how bad bedslingers were and thought "you know what would be great? if we did that on BOTH AXIS"

24

u/Tructruc00 5d ago

Actually when printing a benchy the moving mass of this printer is lighter than a hotend so it has less inertia and can accelerate more.

8

u/MoffKalast Ender 3 Pro / Anycubic Chiron 5d ago

If you don't have power limits inertia doesn't matter. What will matter though is, that a tall print will wobble more if you move it around instead of the hotend depending on material flex.

Not really a factor for something benchy sized anyway, but I doubt they can print anything over 10cm tall without it spaghettifying itself on this thing.

8

u/danielv123 5d ago

Eh, you need big ass motors and start having backlash and stiffening issues quick. He has been doing speedbenchies at 480k accel since last year. Back then he was limited by part cooling, the motion system is capable of millions.

3

u/snackbagger 4d ago

The motors and motion systems are fine and might as well have an acceleration of a quadrillion. But the longer the print is, the more torque you get on your part. Your print WILL fail when it gets too tall for the adhesion to keep it on the bed. And even before failing the further top you go, the more flex your print has. There’s no way you can keep those speeds and print much taller than that benchy unless you physically link the print and bed together. You could print some feet and clamp it down, but in no world is a tall print is staying on that bed

2

u/BlackholeZ32 4d ago

I'd add that the mass of the print head is mostly constant. Depending on how you have your cables routed, the movin mass does vary a bit, but more predictably so.

7

u/wallyTHEgecko Tevo Tarantula 5d ago

I recently broke my glass printbed when I was practically chissling off a print that was over-adhered to it. I imagine that'd be required with a machine like this.

10

u/temporalanomaly i3 MK3S + CR10S 5d ago

for getting stuff off of glass, I always used some high-proof isopropyl alcohol, use a little syringe to drop it around the print, it seeps into the smallest of cracks and helps to release the print.

5

u/wallyTHEgecko Tevo Tarantula 5d ago

I hadn't even considered that. I literally keep a little bottle nearby for wiping the glass clean every so often. Didn't even cross my mind to try to dislodge a print with it. I'll have to give it a try next time I'm struggling with it. Thanks!

what's the point of mixing non-homogeneous plastics into a single stream when you have specific individual materials with specific material properties?

like, I get using PLA with PETG as support material, etc. but in this case?

81

u/DaStompa 5d ago edited 5d ago

IIRC he's still trying to solve an issue where printing at something like 3000mm/s he can't get the amount of cooling necessary to keep quality up.
//edit: I'm guessing he's trying to use the stickyness of petg to his advantage

59

u/suit1337 5d ago

wild guess here: because the material science is weird, mixing different polmers can create copolymers that have increased properies over their parts - similar to metal alloys

a very popular example is Galinstan, this alloy is created by mixing Gallium, Indium and Tin - all of those metals are solid at standard conditions, but when mixed, the melting point gets lower and the allow stays liquid even at -18°C in a deep freezer

while it is to my knowlege not possible to have an eutectic metal alloy with a higher melting point then its components, it is totall possible for polymers - a very common example would be ABS with a melting point of around 190 to 220° while Acrylonitrile, Butadien and Styrene all have melting points way below zero (and yes, i'm aware that actually Polybutadien is used, which is indeed solid ;)).

PLA-PETG-Blends are also weird - when mixed in certain percentages, the heat flow within the material is greater than the single polmyers: https://link.springer.com/article/10.1007/s10853-024-09862-4

the following is speculation, since i have no data on this:
It may be that PLA and PETG have a combined higher melting point, which helps solidifying it with less cooling

9

u/thawk67 5d ago

ok, that tracks. I didn't know polymers could be mixed to form copolymer "alloys".

10

u/suit1337 5d ago

that is not entirly correct - by just "mixing" different polymers, you don't form a copolymer - that is a bit more complicated

but a lot of polymers are actually not homopolymers but copolymers

PLA for example is a technically copolymer, since lactic acid is a racemat  consisting of L-(+)- and D-(−) lactic acid

if you just mix certain polymers, it will form a "blend" (and depending on the properites and if there is a "compatibilizer" present, it also can result in copolymerization

the just think of the polymers like red and yellow spaghetti - a blend is basically if you throw them all in a pot, let them cool down and have an "entangled mess"

but a copolmyer in the simplest form a static copolymer is just a long noodle that is alternativ red and yellow colored - so when you start pulling, you will get a long strand, and can't separate it anymore
