I like this idea a lot. Based on what you said, I went ahead and printed a couple of bits and tested them for exactly this purpose. The beautiful thing is even if they do damage the wires, they protect you from harm by not conducting.
Dude, why even entertain the idea of these things being silly or uninteresting? We're here because we like you and we like your videos. If somebody doesn't like the idea, they can go somewhere else. Don't even get ahead of it and waste time on anticipating those people. Be confident and comfortable with your style. We like your videos just the way they are!
Totally this :D I'd like to see more silly stuff :D Many people do silly projects. It is entertaining. It can also inspire thinking. I have a similar drywall type ceiling and it would be nice to print some bigger drills for it :D I have attached many things - and right now when I need a bigger hole, I have to get out the specialty drill bits that have cutting surface on the side. I have to go up and then with the side of the bit gouge out my hole from the material. It would have been nice to just print something - especially since usually I only need 1-2 big holes, and ofcourse, in different sizes :D
This is genius. Sometimes your working late and something breaks or you run out of and plastic part can get you by just fine. Better than a full stop and delay in project completion until next business day. Great video
@@anon-means-anon haha. I do it also. Sucess is worth it. Failure is good because you reflect on how to improve the idea. Some people pack up their toys, give up and go home. I say as long as you end up without anything bleeding it was sucessful when we try something new. Haha 🫡
I just found this channel in my feed, I think I speak for everyone when I say bring on more “crazy ideas”. This outside the box idea and testing has earned a sub from me, partly for the unique concept, and partly for the knowledge gained from watching various materials endure high friction.
Honestly I hate it when people say "Why would you?" When they haven't taken any time to think about why. Especially when their answer is "Just buy!" Why would I want to print a custom washer? It's not about printing a single round washer, it's about the times I need one of a specific material, color, height, diameter, shape, with a cut out, to fit in a specific gap, with a bizarre size combination you can't get off the shelf. Think people! Videos about testing one design or one material are not just about that one specific test, they are about how it can be applied in a situation where it's actually needed! Why would I want a 3D printed drill bit? Cheap, can have without traveling or ordering, can choose a specific diameter, can make it chamfered, can avoid damaging something behind what I'm drilling. I can go on and on. If people would think more before they ask people "Why would you?" and say "You can just." They would truly expand their minds and stop wasting so much time in comments. Instead of tearing down every idea you don't understand, find a way to add to the conversation or ask real questions! Not to mention experiments on person may consider pointless can still discover something unexpected, inspire other ideas, and just be fun! If you read this, please keep it in mind next time you go to comment on a video or see someone else comment in a defeatist manner.
So many people have asked me why I print mundane items. The answer is, I LOVE to design them, and it is very often CHEAPER AND FASTER than ordering online or even simply driving to a store to buy something. It's also WAYYYYYY more fun, and everytime I see the thing, I get a sense of accomplishment 😁
3D printed washer are a great thing. Especially using TPU since they can act somewhat as a seal. Printed bolts can be useful as well. The windscreen on my motorcycle is affixed to the frame using nylon bolts, washers and nuts. They act as a safety device in case the rider goes flying off the bike since they will shear before the polycarbonate shatters.
There are plenty places we use soft, plastic washers. For example: porcelain sink, toilet etc. The only reason i did not printed last week because the whole set (washer, bolts, inserts 2x) cost me more less than a dollar. So its not worth the time.
Yeah. In theory it maybe more expensive. But if the next store is far away from you, maybe it's still cheaper just to print it. Or if the seal is broken and it's 2 am.. :)
@@NoIPHUyour spot on. I hated working late. Needing a washer and the effort to make one out of sheet metal is a nightmare. Time consuming, risk of injury etc. we can pop a roll of ASA-GF and model one in minutes. Print in a few minutes. Enough time for a bathroom/snack break before getting back to work. Yes imagine living in Alaska or some rural area and you need simple parts. That can be one hour drive each way saved.
Forget carbide; a lot cheaper metals could transfer more force than the plastic will withstand. Maybe a razor blade or utility knife blade could be formed to a good size insert?
@@iopfarmerI think you would prefer HSS anyways because you can get or make them much sharper than inserts which have a radius and require more power to cut.
This is 100 percent my favorite kind of youtube video -- people trying dumb things that a lot of people wouldn't bother trying just to see what happens. You can GUESS what's going to happen all day, but you never REALLY know until you see it, and sometimes you get surprising and unexpected results.
Edison found 1000 ways NOT to make a light bulb before he made one, and he learned a LOT along the way. Thinking outside the box is ALWAYS a good idea, even if no practical uses come from it. You never know WHAT ideas will lead to the next amazing discovery. I appreciate your imagination and your willingness to show the results, whatever they may be. You have an OUTSTANDING channel. Keep it up!
I wonder if it would work if you: • Used PC-CF as the material • Operated at a slower drilling RPM • Printed a geometry that just uses carbide inserts as the cutting edge so the plastic is not itself the direct cutting material.
Really enjoyed this video and your desire to try things for the sake of testing...also impressed by the variations you attempted and your humor. Subscribed!
FDM filaments always going to have heat issues, but perhaps certain types of resin might have more success as they can both be sharper and potentially harder than the FDM drill bits.
A mind opening concept! And even with the narrow focus of drill bits, they could be useful for speciality applications like a picture/shelf hanging kit for drywall.
I really enjoy these types of videos, you know what the outcome will be but it’s cool to see just how far you can push the materials, how they fail, etc. Maybe a more practical drilling application for 3d printing would be something like a custom sized or adjustable diameter hole cutter using carbide inserts? Would probably lack the rigidity for drilling metal or high precision but could be great for wood projects.
Looks like you've made a machine that turns 3d printed drill bits into 3d printed dowels! I was shocked at how good the metal 3d printed bit worked. That was pretty impressive. Sometimes the exploration of silly ideas leads to learnings that power revolutionary ideas. Even child's playing has an educational component to it. Push the boundaries! Be silly! The real ones will stick with you.
Very interesting! I would love to see an attempt to use 3d printed auger bits in a hand-cranked Brace Drill! It can be difficult to find auger bits for older brace drills, so if one could be 3d printed and last long enough to make it worth the cost of the plastic, it could be useful. A brace drill probably won't get hot enough to melt the plastic, and the geometry of the flutes is different. Sharpness will still be the major problem, but the question is: can you overcome that with brute force? It would be very interesting to watch!
I think the two main issues would be friction heat energy and the hardness level of the bit vs the material. If the material is softer than the plastic, it should work fine, as long as the friction energy doesn’t melt it first. Probably the next thing to try (for fun) is drilling into thicker Sheetrock or softwood (where it worked) and see at what point does it melt. This reminds me of how CNC machines use water to keep things cool.
This was very fun. Given the tortion test results I'm surprised none of them sheared in half. I'm surprised the sharpeness and heat resistance are the primary drivers of failure in this test. Very cool work. A truly cool idea would be a carbine insert drill or end mill that is 3-d printed would it hold up to the torque if the cutting was handled by something else. But please don't waste the money unless a carbide maker sends you inserts. Kennametal or some German carbide maker might be game.
The result was actually interesting, I was thinking that the layers will come apart before they starting melting (at least for the materials that can support higher temps).
a cool experiment, thanks for testing this out. The form of the drill is made for metal. I think with plastik it needs to allways cut and no friction while the turning process. So I'd sugest of steeper blade (while staying stable, if possible?) and significantly fewer revolutions per minute, maybe 60Upm? But It will still melt, but maybe it will cut a nice chip first. ;)
What about making bits for a bit brace? The low speed would cure the melting issues. Not sure if you can get the lead threads or cutter to actually cut though. Worth a try I’d say.
It's all about fun! I trying to design latch mechanism for the case and I testing the flexibility taking into account the thickness, length and the orientation of the object. I hope my testing will end some day :) I don't really trust latch mechanism that is integral to the main part because if latch breaks the entire main part is screw up so I trying to make separate latch that will be attached to the main part later.
I think a high temperature engineering resin would work better, especially for a drill bit this size. Smaller bits would snap easily once they grab. The cutting edge will probably chip in harder materials. Now I want to try this. 😂
Suppose you need a specific size hole for which you have no drill bit? Perhaps taking the hole out to the nearest 64th inch and then effectively 'reaming' a few thou. Maybe the best one would work for a single hole?
For drywall they are a really good Idea, you don't have a specific size bit for mounting something in drywall? 3D print it instead of having to go to the store and buying potentially an expensive bit, they would also make great cardboard bits for kids.
That was not a silly idea. That was an interesting experiment. I suspected that the 3D printed plastics would not be good for much as that's my entire experience of 3D printing. What it would do is to drill through balsa wood which is used a lot by model makers.
Re-design it to take an inexpensive metalworking insert and see if it can drill aluminum. You would need a Peek or PeKK tip to handle the heat from the insert.
They make drills with replaceable cutting inserts in larger sizes, and there are thin sharp carbide(and also HSS) insert available in rather small sizes, a printed body with glued in place or bolted on inserts should be doable(glued down to maybe 10-12mm and bolted on from about 16-20mm and up)
The advantage of 3D printing of course is that you can make the tool any size you want. Assuming it will cut, we could have bits in sizes you cannot just buy.
I would think that plastic drill bodies with hss or carbide inserts would work just fine 😉 cooling is an important parameter, with compressed air maybe?
Knowing where a material does work is only half of the story, there is value knowing where it is not 😉 And good times keep illness and old age just a bit farther 😁 For soft thin wood, punching might work better. Let's not take things too seriously. Or maybe just a _bit_ : With carbide insert(s) we might see quite different behavior at least on medium wood (pine, spruce) if the drill itself can keep handle torque. Safety glasses recommended 😅 Commenters, don't be wet blankets: enjoy the technology and (plentiness? multiplessness? multitudeness?) plurality(ness) of ideas. We _can_ successfully 3D-print _helper_ tools, covers, dust extractor parts - and yes, *big bolts* for tightening hand saw to broom stick adapter (for dropping snow from roof edge, in case you didn't know or didn't have snow on roof 🙂) etc. Real carpenters do 3D-printing in ways we, with a thumb in middle of the mouse, don't even dream about.
As I'm assure your aware, friction is your barrier here... So you need a filament that can resist friction and deflect the heat. So Nylon CF would be stiff, and be self lubricating, but would most likely still get too hot and deform. So I'm thinking for consumer grade filaments, Polycarbonate (or PC-CF) is going to be your best bet to resist the heat. Obviously PEEK and Ultem would probably be best, but that's not gonna happen.
Heat is obviously the enemy here. So rather saying this is a silly idea, consider it an early one. Metal drill bits are not designed to dissipate heat. Consider ways to cool the bit while drilling, whether it be fan blades or veins or whatever you can come up with. Then you want to redesign the bit to “cut” with minimal friction. Alternatively, find applications that don’t require a ton of friction. Like drywall or even foam!
These would be useful if drilling into drywall to mount things to the wall so you don’t accidentally hit power wires.
Infuse the material with some sort of abrasive grit and it might work quite well on harder things like metal.
or use it to make an ancor for a metal screw.
Great idea.
I like this idea a lot. Based on what you said, I went ahead and printed a couple of bits and tested them for exactly this purpose. The beautiful thing is even if they do damage the wires, they protect you from harm by not conducting.

Nice one. This is why we love YT - someone else tries the whacky ideas so that we don't have to. Sure this one didn't work out... but it *might have*.
A good illustration of the hardness of the materials, or lack of it, which is more intuitive than numbers alone. Thanks!
Drilling expanded polystyrene would probably be fine.
It might be interesting to see if you can drill PLA with a PPA-CF or ASA/ABS drill bit.
FDM filaments always going to have heat issues, but perhaps certain types of resin might have more success as they can both be sharper and potentially harder than the FDM drill bits.
Never would have thought to try this. That was quite entertaining.

Interesting. Would Electroplating the parts change these results? Maybe some of the heat gets dissipated sooner, iex. dry wall...
very fun, I was actually rooting for the ppl-cf on the second try ahaha
Use water to cool it while drilling
I wonder if the high temp stuff by FormLabs could actually make a decent bit?
For the sake of curiosity it might be interesting to get one of your sponsors to print one out of peek CF or something.
This one is genuinely interesting to me, is it feasible to 3d print one time use tooling and such.
That was not a silly idea. That was an interesting experiment. I suspected that the 3D printed plastics would not be good for much as that's my entire experience of 3D printing. What it would do is to drill through balsa wood which is used a lot by model makers.
I wonder what would happen if you add a cutting fluid, even just water, to keep the drill bits from melting
PPA-CF was not melted, it was not strong enough on sharp edges. Temp resistant over 240°C
Very interesting!
I enjoyed learning more about what 3D printed plastics suck at 😁
Like really badly, even the "metal replacement" one!
Re-design it to take an inexpensive metalworking insert and see if it can drill aluminum. You would need a Peek or PeKK tip to handle the heat from the insert.
You forgot the main thing: coolant! It is especially needed for plastic drill bits.
For PET and PPA, it was not the melting what case the problem. It just wasn't sharp/strong enough on the cutting edge.
I wonder how much of a difference it would make to drill by hand. So much slower, probably no difference, but curious.
They make drills with replaceable cutting inserts in larger sizes, and there are thin sharp carbide(and also HSS) insert available in rather small sizes, a printed body with glued in place or bolted on inserts should be doable(glued down to maybe 10-12mm and bolted on from about 16-20mm and up)
If it wasn’t so expensive and damaging to the hotend, you might have had fun making them out of PEEK. I found this a fun little video BTW.
The advantage of 3D printing of course is that you can make the tool any size you want. Assuming it will cut, we could have bits in sizes you cannot just buy.
what if you cooled the bit ?(like when drilling rock or concrete)
I would think that plastic drill bodies with hss or carbide inserts would work just fine 😉 cooling is an important parameter, with compressed air maybe?
The hardness and temperature impact on the different plastics is very interesting for 3d printed gears in thinks like desiccant dryers.
I like this video because it shows what is not possible.
Try again with cooling fluid like ice water? Maybe design the bits to flow coolant through them?
Did you anneal the PET-CF and the PPA? Those two materials need to be annealed to get their advertised properties
Looks like you need a high temp printer for stuff like PEEK, PEKK, etc., which have a higher meltpoint. 😁
I'm afraid i didn't unsubscribe and I am still a patron :)
Knowing where a material does work is only half of the story, there is value knowing where it is not 😉
And good times keep illness and old age just a bit farther 😁
For soft thin wood, punching might work better. Let's not take things too seriously. Or maybe just a _bit_ :
With carbide insert(s) we might see quite different behavior at least on medium wood (pine, spruce) if the drill itself can keep handle torque. Safety glasses recommended 😅

Real carpenters do 3D-printing in ways we, with a thumb in middle of the mouse, don't even dream about.
how much did it cost for fun for the 3d printed metal one ?
Straight to the point, tested everything to its full potential, and summed up nicely at the end. 10/10 would watch again
I was 110% sure that at least some of those are working :D Why else you make video about it.
