I’d love to see more about your plastic soldering technique and how well it works. I’ve tried it a few times on different types of plastic and never gotten it to actually work well.
I have had pretty good luck heat welding PETG. I use a temperature controlled heat gun that is part of my soldering station with a small nozzle and treat it just as I would gas weld with a torch and wire. I use a chunk of filament as filler, and prepare the joints as per normal welding practice. I add taper grooves for more area and design the joints as standard welding overlaps. One other point, the area has to be 100% infill because it will just shrink and collapse if there are voids
As a fellow longboarding Clemson alum, I can also attest to the emergency Mach 8 dismount coming back down from Kite Hill after having to move my car to make room for tailgating. Super cool builds!!!
3D printing bearings are pretty okay for non "heavy" things (what is heavy). I use metal BBs, print the inner and outer ring and a slightly undersized hole to sneak in all the BBs. Filament spool holders, lazy Susan, fidget spinner (whatever you get the point) they work well
I've did a good deal of skateboarding in my teens. One trick for beginners is to practice standing on the board on carpet or grass, leaning your feet left and right. This will give you muscle memory on how to keep your center of balance under you without the danger of the board shooting out forwards or backwards, as they are wont to do.
Was that a Spongebob reference at the beginning?! I LOVE THIS CHANNEL! -Actually, the amount of Spongebob references in this video is making me love this channel even more than I already do!
1:20 - Man I feel this; my Artillery X1 is just discarded in a corner.. I feel kinda bad. He was loyal; despite me spending hours by-weekly screwing with it.
1:51 I did this exact thing the other day when designing a dust collection system for a sander. Wasted a decent amount of filament for something that would’ve taken 4 seconds to do🤦🏼♂️😂
Omg I love this!! In 2007 I broke 4 toes skateboarding. But then I got back into it in 2020, and ended up 3d printing a penny board for fun! It wasn't 100% 3d printed, but it was pretty close!
you can't 3d print film. maybe you could print the base layer but the rest of it would need a bunch of people in a lab setting creating a pointless gantry to print
"im afraid of stepping on a skateboard after having an accident with one, so im going to completely 3D model and 3D print a skateboard with very little structural integrity myself and ride it" Ooookaaay
Skateboard decks are concave wouldn't that help with the stability? Or is it just that much easier to print it flat? I've been thinking about 3D printing forms for a press to make Penny and nickel board decks (out of wood).
This is awesome, you are awesome, please send this to braille 👍 Also, I wonder if it would make a difference in strength if you used something like protopasta htpla or reinforced nylon
I don’t know much about printing plastic, but would it be possible to embed metal parts into the high stress plastic parts? I am thinking interlocking metal parts that can be coated with silicone spray and then inserted. Sort of like metal bones with plastic flesh.
cant believe you could actually had fun for a few minutes before breaking. i have an idea for you to try (i failed), build a skate/longboard braking system!
Simplified 3:37 (P*L^3)/(48*E*I)=max displacement: P=force L= length E= material stiffness I = area moment of inertia (the stiffness of the shape) I = (b*h^3)/12 The important part here is the h^3 and the L^3. L in this case is the length between the wheels and h is the thickness of the bord. If you make L longer you make the bord way more flexible (and weaker) and if you make the bord thicker you make it way more stiff. If you double the thickness the bord gets 8 times stiffer. This is good to know.🤣 If you want to know about the details start by looking up Euler-Bernoulli beam theory, it is easier that it looks.
@@bermchasin Well yes getting to the stiffer part might be simple. If you get to the h^3 and L^3 part by your self I would be impressed, I don't think that is common sense. (I think that is Engineering). But if you think this is too easy you can keep adding to the complexity. You can experiment with different cross sections, try unsymmetrical cross sections, different loads, you can combine different materials (sandwich structures). And if it is still too easy for you, you can start looking into global and local buckling of beams in bending. It is like they say. If it seems simple to you, it's just because you do not understand it deeply enough yet.
or you could just plug it into CAD and let it run the stress analysis for you. It seems simple to me, because it is a simple prinicple. Most skateboards are made with layers for a reason.
@@bermchasin hehe. As someone who made a living doing FEM analysis for 10 years, I have seen my fair shear of people just plotting some numbers into a CAD program and then looking for red areas on a stress plot. I think FEM is a super powerful tool, but it should not be used as a black box. The program gives you the answer to the question you are asking, but for it to be useful you will need to understand the question you are asking. If you don't understand the assumptions of your boundary conditions, your element types, you contact definitions, your material properties, the numerical model used to solving your equations and much much more, you might not check your reaction forces, mesh converges and so on. And then if you get a result that shows that your design is not strong enough then you cannot make a simple estimate to check if you might have entered a wrong value somewhere and you do not understand load path and structure enough to suggest a better design. Say you get a pure bending stress of 120 MPa, and you can only allow 60 MPa of stress in you material. Now how much thicker do you need to make your part? (Hint it does not need to be dabble the thickness). I have never regretted learning beam theory, honestly I have only regretted learning very few things in my life. But the list of things I regret not learning is nearly endless. I have not seen a skateboard in many years. But as i understand it a skateboard is just made out of cheap plywood. I don't think the goal it to make it as stiff en bending as they can, my guess is (since wood is stiffer in one direction) they want it to be cheap and reasonably flexible. They might want some dampening, and maybe the don't want it to be too light or too heavy. Otherwise they would be designed as snowboards and skies.
@@Petch85 sometimes you can learn so much, that you forget the basics. Its a simple plastic skateboard deck designed for 3d printers, no need to overcomplicate it.
Im here from Kuris Conners video about the command center gaming chair (its not a chair) Really cool that you helped him out with that video This video is also very cool, Im super impressed you went all the way and made a full board after the penny board Im subscribed now and can't wait to see more from you
Probably needs to at least double the size of those wheel truck axles and bearings - and ABS would prolly help a lot too. Still, exactly the kind of engineering chaotic good I need on a Sunday afternoon. Roller blades?????
I feel like this is a PSA about why every experimenter/inventor/"maker" shop needs to have some subtractive machining capabilities in addition to printing, because being able to make even just a few smaller parts out of aluminum or even hard woods would really improve the overall strength of these systems like the skateboard.
Every video of yours just makes me feel like I’m watching Moon from “The Great Norths” crazy inventions later in life. Same energy and you sound almost identical 😂 amazing vid as always
The Dan reveal is great.
I was so genuinely surprised yet I also realized immediately that I shouldn't have been knowing how chaotic she is. laughed my ass off
especially because youtube took all my pixels just before the switch.
I had to rewatch the whole segment after the reveal, and now I've developed trust issues.
If you look close enough you can notice the difference in the pants, I had to do a double take and pay better attention myself😂
They freaking caught me off guard 😂lol
He said "That's my wife" and I believed him. But then I had to rewatch the whole video just to make sure there weren't any more secret Dans. My trust is broken but my engagement has never been higher.
Never throw old printers away, they have feelings
Don't tempt me, I'll take them off your hands and modify them beyond recognition.
There is absoluty no way that the real integza only got 65likes and after 5MONTHS i am the first reply. Why???
I will smash every printer that is complicated to connect to my phone/computer!! Lol
you should put rockets on her skateboard
8:28 I've once heard that an engineer is a person, who forgot more math than you ever knew
And I wholeheartedly agree with that
Her crazy dorkiness scratches a humor itch that doesn't often get scratched.
The stunt double reveal is one of the funniest things I've seen on RUclips in a long time 😂😂😂
I went back two times to figure out where exactly they switched, before finally noticing that the music makes it very obvious (I was looking at the shoes...). Yes. I am very smort.
Ah yes, the classic engineer wanting to skate but being too scared after falling once. I am very familiar with this
go out and skate!
@@bermchasin I would but it's still too wet where i live rn and i dont want to ruin my bearings, the weather should get better soon though, so i will!
@@rat-in-a-suit ceramic bearings!
@@knoopx I've honestly never heard of ceramic bearings, wouldnt they be quite brittle though?

Unhinged is a lot for this
@aninseems like a very basic idea to me ...im sure others have done it actually
I respect a woman that can go full goblin mode. That's the reason I subscribed to this channel.
That reaction to being told to throw away the prized first printer was on point
I think Braille Skateboarding still does their "you make it we skate it" series.
Could be fun, although the guy who runs that channel has done some funky stuff, allegedly pumps ridiculous amounts of money into scientology rather than paying his staff properly.
Yeah, what's left of Aaron's Scientology revenue generator.

It all depends on the type of plastic you use. You can solvent weld ABS with acetone.

the terror is that man's movements at 3:05. Brother jumped off and just stood for a solid second
I love the energy of these videos. If more people were this psyched about hobbies, the world would be a better place.

I love how consistently you start a project before realizing how cursed it's gonna be. Never stop to think.
I love her chaotic energy it's the best.
I had to go back and rewatch the actual skating scenes! Well played!!! 😆😆
I hope you have a filament recycler. If not, I hope you make a video about getting and setting one up.
Was that a Spongebob reference at the beginning?!

Had literally finished watching almost all your vids and then this dropped two hours ago. Great work Emily. 😂
1:20 - Man I feel this; my Artillery X1 is just discarded in a corner.. I feel kinda bad. He was loyal; despite me spending hours by-weekly screwing with it.
you could always donate it to a local highschool, theyd use it till it dies
no free 3d files? 😥
Stunt double reveal changed my whole perspective on life! Caused me to rewind & notice the knee pads! Friggin brilliant!
1:51 I did this exact thing the other day when designing a dust collection system for a sander. Wasted a decent amount of filament for something that would’ve taken 4 seconds to do🤦🏼♂️😂

Skating montage was RADICAL!!!!!
Bro kindly asked for his camera man immunity after realizing he almost died
The music selection for the skateboard test was a rollercoaster of emotion for me.
I'm always excited for your vids.
Next up: 3D printed camera w/ 3D printed film! I bet you could do it.
you can't 3d print film. maybe you could print the base layer but the rest of it would need a bunch of people in a lab setting creating a pointless gantry to print

this has worked 3x better than i expected
Make a life sized B1 Battle Droid please
AND a bb-8 :)
Ooh, that would actually be awesome!
Great design, its definitly not gonna break appart at all!
love this skateboard and that toilet you printed haha😆 Looking forward more interesting project!
As an automotive teacher, I love seeing your adaptation to problem solving! Especially with the bearings.
2:51 Just like god

Skaters like me watching this are cridging so hard at this video 😂
This video is hard to watch for true skaters
I am literally yelling at my phone “THE BOARD IS FLAT YOU NEED CONCAVE” 😂

i love the vibes of the video and the crazy idea to entirely 3d print a skateboard. And it was actually working
Not sure if this ended with an ad spot for Brilliant... or a hit piece.
I made a skateboard!
everything breaks...
I made a SNOWBOARD!
🤣🤣🤣🤣 “Alright, let’s see what you broke…”
Emily's videos:
"What could possibly go wr- wait, it's actually w- oh, yup, there it is."
That's so cool! How can I get a copy of the bearings that you used? Loved the video, it was something I also always thought about :)
Great video! Especially how you put the sponsor segment at the end ❤

Awesome video Emily! Do you post the files for the board anywhere? Would love to try printing it using a les brittle plastic.
Great video! The ending is so unexpected lol
Last fall I also printed a 55cm board. After my exam (school) I want to print an 80cm board from PETG and PCCF for the axle.
Nice work!!
Why not using ring solid bearing? Maybe on petg?
Still amazed at how well it worked out
