Assembling & Testing a 3D Printed Skateboard. Does It Work. Yes. Sort Of. 3D Printing Cool Stuff!

The skateboard I 3d printed using recycled PET filament. The skateboard would be supported by two smooth rods, a threaded rod would hold together the middle parts, and the trucks would attach and keep it all together. Would it withstand me? Or, how about my 9 year old son?

It would be JST or something bc it wouldnt have zone in the name, so Joel Standard Time

Aww, we wanted to see YOU ride the skateboard! :P

[@sebastiancodesido7614]

true it would be funny

[@tomhsia4354]

#FullJoel

[@ecbrd8478]

nice AvE reference with the safety squints

[@charley6799]

safety squints are much older than AvE lol

[@Willielikesmonkeys]

On Penny boards they're made of a grippy silicone like material with no actual sand paper. Maybe either a dual extrusion or separately printing the top out of a rubber-like flexible material? Also, adding some sort of interlocking system would probably add just enough strength to really make it last.

[@shadowcard6923]

Using aluminum angle iron between the trucks likely would’ve made it so an adult could stand on it. It was a trick used by a DH longboarder to get added stiffness

[@tessbodley]

The black "pads" are called risers. :D You need to fortify it better and send it out to me here in L.A. and I'll test the next version at a skate park here. Also, yes, all boards should have some grip tape on it. Dope that someone printed a board! I'd love to try it out. You definitely wouldn't need to wax any crubs or anything before sliding on them. I hope they do a modern street deck design, that would be fun af.

[@TeamPanicRobotics]

Very cool! You should try printing some wheels for it too I've been experimenting with some 2 part printed wheels: Pla hubs and TPU tires they seem to hold up quite well. I might put up a video with my results in a few days

[@wordreet]

Can you print a one piece complete deck on you biggest printer, maybe corner to corner across the bed? That should increase the strength nicely. And, yeah, YOU need to ride your creation Joel! Using your kids as guinea pigs. What ever next? Ah, wait, do you have them insured? Hmmm,

[@toastrecon]

Honestly, I don't think that this design will ever perform well as-is. That threaded rod is really soft and is only "designed" to support a load in one direction - along it's axis. As your son found out, if it's subjected to a bending load, it's done. All of those threads that are rolled into it act as stress risers and concentrate all of the stress at those little valleys. Another danger is: as the board is ridden, that threaded rod could fatigue and harden and then break, which would cause the board to come apart. No way is the remaining rod keeping that thing together. Some ideas: use steel bar for the inserts. Maybe aluminum, but even that is pretty iffy. You could also print some ribs or flanges into the bottom of the deck so that the steel rods run through the middle, and the segments are held together with the flanges. Most of the bending load would be taken up by the steel rods, and the flanges with nut/bolt pairs (with washers) could keep the segments from pulling apart. Maybe another cool aesthetic cool be to make the skateboard segments mate via a edges that were a few dovetail joints? Snap them together, push the steel rods through, and then put small bolt/nut combos in the flanges on the underside?

[@boomerangfreak]

All good ideas yes though I can't help but wonder how this design would perform if it were to be designed to use profiled tubes like triangle or square shaped. Using that in carbon fiber tubes that are bit bigger than what they seem to be now, I do think this would then be a very usable cruiser board. But ofc a total redesign would most likely offer the best solution even though I still have my doubts this would ever become common practice as well wooden boards, let's just say there is a reason they are so widely used.

[@bigboy6704]

Could I use rebar?

[@toastrecon]

Lots better than the threaded rod. I might also look into the steel bar that you can get at Home Depot. I would say that you could also look into carbon fiber tube that you can find online. A lot more stiff, really light, and could be glued in with epoxy?

[@bigboy6704]

David Clawson sounds like good idea.

[@toastrecon]

That is true, but it still is a decent engineering material (as seen in many aerospace applications). Catastrophic failure, in my opinion, is more important of a consideration where you're pretty sure there will be severe impacts or shocks. Think of car body panels where you want them to be able to deform without shattering because you want them to absorb the crash impact. Maybe in the form of a fuel tank on a car where you'd rather it dent than crack and then leak. In this case, if you were to use correctly-sized CF tubes for the interior structural spars, I'd think that the chances of them being more prone to breakage than steel or threaded rod would actually be pretty low. They wouldn't be exposed to rock chips or sliding on rails where the CF could be damaged or abraded, and if the board were shocked with enough force to break the CF, chances are that the rider is hurt anyway and the plastic parts are toast.

[@paulvo7818]

Hey Joel, try separating the board into 3 parts to avoid the joint right in the center of the board. The bending moment and therefore strain is highest in the center and that shouldn't be the location for weak points. Engineers know that as 3 point bend. Good luck!

[@ah64tom]

Another fun and entertaining video. Thanks Joel and David!

[@quentincampbell5865]

Nice Joel. Making things and experimenting with your boy. Time with children is always precious! And they learn from/with you. Are you going to make a follow up video with improvements?

[@buildersmark]

Just out of camera frame add a second monitor & power point a teleprompter for David that you can mouse click to advance for him. Consider printing the 2 middle sections as 1 piece also if that's possible. Maybe add pieces of bar stock from truck to truck.

[@greggeshelman]

It needs some type of interlocking at the joins. Print both faces flat and use butterfly patches or keys glued into the bottom side. That cheap smooth rod is too soft. It needs hardened steel rod, like is used for 3D printer rails. Can't cut that with bolt cutters!

[@TylerOstergaard]

man i should have used the safety squints now i have to wear a pirate eye patch :P

This is awesome... more Dads need to be this cool... "nerdy" ;P

[@StopChangingUsernamesYouTube]

"It kinda re-formed." I chuckled. "It didn't break; it exceeded specifications and became modular!"

[@jasonbaker541]

Cool video. Your Son is awesome! Clearly you have been a good Dad because he has such a positive perspective on how he describes the skateboard experience.

[@brandon3883]

I have to disagree with your blanket statement of "goodness", Jason: my teenage son has turned out _way_ better than he ever should have given that he's got me and my wife for parents, so for all we know David might be a great kid merely due to genetics rather than parenting. XD

[@jasonbaker541]

Well I was considering making some clever statement that Joel loaded great filament into his wife's extruder and made a great print, but was not sure how that would be received. Nature/Nurture is an age old argument, but parenting can have a definite impact on your child's perspective and behavior, but yes you are correct, there is a chance it was just genetics, which by the way came from the parents also so either way Joel is a good Dad, genetically or sociologically.

[@3DPrintingNerd]

+Jason Baker I cannot argue with Jason's very valid and awesome point. #GreatFilament

[@brandon3883]

+Jason Baker LOL I was (obviously, I thought) just joking, nature/nurture debates definitely do not need to make their way into Joel's comments section, that's for sure... (I like your joke, BTW, although wouldn't it be Joel's filament _and_ extruder, and his _wife's_ build plate? ;P)

[@KuraIthys]

... Not really. Biology is weird. Yes, I know, visual imagery, but uhh... In terms of actual... Metaphor of how children happen, the first version is probably more accurate. XD

[@ImpatientTurtle]

Watchout Joel, I think Davids getting ready to take over the channel soon. He was pretty quick with the "As always, Hi 5" haha.

[@shadow_stalk]

awwwww man you should send one of these to BRAILLE SKATEBOARDING on youtube. they would love one of these!!!

[@KuraIthys]

Recycled PET huh. I hope at some point to have a 3d printer and plastic recycling setup that can handle that... PET is both by weight and volume probably the bulk of my current recyclable waste... Being able to re-use it myself would be awesome...

Gluing the pieces together might help with rigidity. How much infill?

[@briansouth9325]

I bet a laminated board would be even stronger

[@RWHITT]

I wouldn't mind printing one of these, annoyingly the 3d printer arrived faulty! :( Could be worth swapping the smooth rods for carbon fibre tubes or rods, likely still flex but not bend and stay that way :) Keep up the good work.... your lad is cool! high five :D

[@sleepyzero5363]

hay Joel use high carbon steel rode's

[@fntsmn]

O damn that is strange! I guess I maybe used more tough rods, I'm pretty sure I'm more heavy than David and I used the board for more than 1 months without any issue. Maybe one day I will make a new version of it :D

[@3DPrintingNerd]

Maybe David is just TOO EXTREME :)

[@fntsmn]

Ahaha true!

[@tamamatheus]

If you put the rods in horizontal will be more stronger ?

[@AhmedE67]

Do you mind posting the STL file, if it's ok with your friend ofc, so that we can print out 3D printed skateboards too?

[@MeditationOasis_BaGRoS]

Try with steel pipe

[@gioromeo]

Hi Joel! Were the rods hollow? If that's the case than maybe you could try solid steel/iron rods.

[@AkashKumar-px7rw]

Giovanni Romeo I don't think they were hollow. You don't cut hollow rods with clippers. Also, I think a little kid jumping on solid rods of that width is enough to bend it. I assume it wasn't hardened steel that's why it bent

[@leocbarreto]

From now on im gonna let the adds play! :D

[@JasonGroom]

Leonardo Barreto if it is a show you like, you really should as that is how a KZbinr earns ad revenue

[@TonyRios]

Thicker rods?

[@mattfarrar5472]

Hey mate any chance you will review a Tronxy X5s? mine is arriving tomorrow(my first printer :) )from all the research it seems like the best bang for buck printer at the moment and i'd love to hear you thoughts on it, and surely Gearbest would send you one ;)

[@justinyoder8447]

I was wondering where you suggest getting good quality filament from because I will be receiving my first printer in the next few days and would like your expert opinion. Love your videos by the way!!

SAFETY SQUINTS

[@noahhornbacher7864]

your son skates mongo pushing

[@cucubits]

Really? a full face helmet for pushing around a skateboard? That kid's got a bright future, that's for sure :)

[@kendarr]

Oh my gosh you got a regular skateboard wheels and trucks, not a penny one xD. It been able to flex is a good thing, otherwise it would shatter

[@nikimarkieren7848]

my 2 bobs worth as i dare say the redesign of the skateboard has no dout been hashed rehashed and then one more time because he was getting into the job!. So all i have to say is when you want strength along a board be it surf,skate,or ironing? (hey I like to push hard on my collars lol....you Need lateral stringers eg: stiff flat say 3/4 " wide or 20 mm Steel - Carbon Fiber - Hard Timber or any other material thats quite light and resisits bending ,then put on it's side it will give incredible lateral strength even 3mm aluminium will be strong enough to take your weight Mr Joel Print or make slot's down the boards length so they fit into them snug and Epoxy the crap out of them :-).....That'll dooittt Yehhh. cheers from Australia Joel .... P.S. Love those HUGE printers (actualy I love all 3d printers theyre cool tool Yeh! Your doing a fantastic job there 3DPN looking forward to lots more fun in the printing Sun.....Cheers

[@goeland86]

Hey Joel, wouldn't you want some kind of underside ribs to help hold the torsion a bit better? Maybe using the rest of the smooth rods you chopped off would help? Like this: static1.nordic.pictures/4150810-thickbox_default/plastic-skateboard-28-flipgrip-board-nijdam.jpg

[@jjvansly]

Cool project. The bending issue is because the rods are on the neutral axis for bending and round rods don't have a very high moment of intertia, which affects bending. The plastic parts did not help because they were not glued together. Gluing the parts together would help, but is probably not enough by itself because half of the plastic joint will be in tension and the other half in compression, and I don't know how well the plastic joints will handle the tension. Taking shorter rods or metal plates and gluing them to the bottom of the skate board between the tracks will help stiffen up the board also by shifting the neutral axis down and putting most of the plastic joint in compression.

[@axelgallegos2817]

Your son is pushing mongo. There's nothing necessarily wrong with pushing mongo, but it's not the correct way to ride a skateboard and makes it more difficult. If he's going to do more skateboarding he should learn the correct way to push before he gets too comfortable pushing mongo.

[@bluedeath996]

I am not sure the 3d part adds anything useful to the structure. I Feel like if you attached the trucks directly to the 3 metal bars it would work just as well. A tongue and groove design would improve it a lot.

[@itnaanti]

Thumbs up for David's fist-pump after "you're just too extreme!"

[@133tmilbs1988]

Joel re try it using 1 cutout of 1/4ply wood on the bottom of the board between the trucks and plastic making the frame less flexible

[@codyhubert6178]

[@TacBlades]

I think it was a good experiment, if its made again then I would go for flat steel strip stock would be strong but with flex :)

[@valveman12]

If you use spring steel smooth rods, it will not deform.

[@wi11y1960]

Use spring steel for the rods. Since the holes are triangular you can also use hexagonal rods

[@texnole2447]

Aw i was hoping to get the print download. I think it would have been cool to make!

[@JD180018]

Great video! I was wondering if you ever add the braces to make it stronger?

[@youngsuhlee1858]

You should add more wheels, so the boy's weight is distributed by more wheels.

[@biohazardjackson63]

Try carbon fiber rods

[@marius_8320]

I think that aluminium or steel profiles, would work much better. The carbon fiber rods could shatter.

[@DingDongDaily]

you've obviously never handled carbon fiber before. the sheer strength of solid carbon fiber rods would be ten fold of the steel rods. it would also be a fifth of the weight.

[@DingDongDaily]

David dude i fly carbon fiber drones everyday. carbon fiber does not fail catastrophically, especially on a skateboard where the only force is coming from one direction.

[@robokid20001]

MuchFly Wow The carbon fiber plates that make up props/quadricopter body panels are much different than a rod of the stuff. Carbon fiber is not ductile and is super super brittle. It would snap immediately upon jumping on it.

[@BazilRat]

Only if you push it past its limits. I mean, there's a reason you can get automobile driveshafts and /safety cells/ made of the stuff. If the carbon fibre is strong enough, and thick enough, it won't be anywhere near those limits.

[@fhuber7507]

Poorly designed board. The way its assembled is designed to bend and break.

[@daisywei7731]

yes, should be possible

[@lunaherron]

i would suggest a small medal plate under the board. and as you said some grid tape to traction

[@sebastiancodesido7614]

what is cool is since all i watch is 3d printing vids all i get is 3d printer ads i let the ads play

[@tablatronix]

why does it not have interlocking seams?

[@johnecker]

[@3DPrintingNerd]

+Noah Mcelwey oh, it was given away at Portland Mini Maker Faire earlier this year

[@noahmcelwey2598]

3D Printing Nerd oh, what a lucky person who won that, I will be buying one so on

[@3DPrintingNerd]

That's great! It's a very decent machine for the price - for sure.

[@FuriousImp]

Hey too bad you didn't catch the pun "don't get all bend outta shape!"

[@Zeldur]

I'm surprised it was the rods that failed before the 3D printed parts. Maybe if the joint was distributed then it would work better.

[@orbitalair2103]

yes, a zigzag pattern(instead of a straight line) with an interlocking spine(under) along the centerline. But yes, boards take a lot of loads along its thinnest part.

[@boomerangfreak]

For me personally that was totally not a surprise tbh. The steel/threaded rods aren't strong enough. Tho I will say I expected it to take some more effort to make em bend this drastically.

[@jimmyrodriguez5887]

You know, I was scrolling through and saw the title of this and thought, "Nah, I don't even skateboard". Then I saw it was posted by you and I hit play. LOL. But I thought you said that you were going to ride it?

[@3DPrintingNerd]

+Randy Alexander I was going to after it withstood my 9 year old. I figured getting on it would add more insult to injury :)

[@RELLOH-]

Oof he pushes mongo

[@3DPrintingNerd]

Oof he is very active and pushes and skates and plays ball and hockey and soccer and I don't know how to say your username out loud. :)

[@MrNathanstenzel]

Maybe use a pair of door hinges in the middle or put C beam down the middle of the bottom? The door hinges will probably be cheaper, but less useful. The C beam would make it really strong if the wheel mounts are attached to it. That would make the 3D printed part just a platform on a nice sturdy base.

[@3DPrintingNerd]

Very interesting idea, especially considering I weigh quite a bit more than my son :)

[@ricardobfe]

Wood defeat the plastic again.

[@Crits-Crafts]

Joel (referring to how solid the first set of trucks attached): Thats not going anywhere me (only 1/2 paying attention): No of course its not, you still need to attach the other 2 wheels first... oh...

[@cahproductions4695]

Dang David! Nice work! That's great you finally got the chance to put the board together. Have you considered sending a 3D printed bored to the people of Braille skateboarding? They do a great torture test! They have even skated on 3D printed wheels!

[@alandelarosa9842]

typical Washington always raining

[@sjbolton72]

glad you guys gave it a shot and were both very positive with it. While the obvious bracing would be to add 90 degree angle strips underneath in the model for strength and reprint. But maybe a more practical approach is to make the board like most boards are made: in layers. print the board thinner a few times and sandwich glue them together?

[@Jman116Films]
