In the previous video I showed a brief segment showing this connection that I created, which is my take on an old and wonderful connection which has been used in Woodworking since the dawn of Woodworking. Having made many a dovetail connection by hand in my days as a Woodworker, I thought it was a connection worthy of some attention in 3D printing as well. In this video I show you the process of how to create a variety of different levels of sliding dovetail connection in Fusion 360 and of course we 3D print them and see how they come together.
For this video, I've used the Bambu X1C and the QIDI Q1 and the results were quite good from both printers. The filament was Bambu PETG-CF in Brick Red and in Titan Grey linked below (I receive a small commission if purchased through my link and it helps me continue to make videos like these):

I think you could do it in woodworking, but it'd be with a router and a bit with a bearing on it to use as something to follow the curved path. it'd take a lot of fine adjusting though and probably not worth it.

@@atomictyler Yep I was thinking the same in my head so I added the word practically haha. Would be a fun challenge!

@NeedItMakeIt 2 месяца назад

@@atomictyler I first had this idea 20 years ago and I used it on my final project in College, I had 8 legs connecting into a central curved body with the dovetail connection and they were also tapered, it was incredibly difficult to pull off, unfortunately the end result wasn't as good as I had hoped, the legs were slightly undersized and the table vibrated more than I expected. I still graduated luckily! It's about 100X easier to do in Fusion than by hand! Certainly possible in wood, but like you say, it's not worth it unless you enjoy torturing yourself.

@jacobmoore4665 2 месяца назад

You can do the rounded part fairly easily i imagine on the router table with a dovetail blade, and a jig that translates the curve you want to the cutting blade of the router. Stop short for the female, cut the end off for the male, go back and chisel the inside of the end wall to flatten it out in order to receive the whole male part. Honestly, id make a video on this in response. I just got a 1,600sqft workshop after years of hard work(im 24) and I've been wanting to make a youtube video.

@stew675 2 месяца назад

Absolutely awesome tutorial Mike! The creation of joining pieces seems to be something of an art that is often overlooked in a world where we can just buy larger printers, but I think you've really opened up a lot of opportunities for those with smaller build area printers here.

@NeedItMakeIt 2 месяца назад

Nice, thank you! A slightly bigger printer is okay, but too big, I'm not so sure it's a good idea, they'd need to be enclosed, insulated, heated and then even after all of that, you're still going to have problems with shrinkage and warpage. I suppose it depends on the material, I think at least for now until bigger printers are perfected, it's better to connect the parts. Can you imagine making a large print and your print fails, that's an entire print and all of that $$ down the drain, at least with separate parts, you'd be able to salvage some of it. I'd be willing to test a big printer down the road, I just am not convinced that printing plastics on a large scale is a great idea. I say yes to printing Concrete for houses on a large printer though.

@schrectacular 2 месяца назад

Really cool. One advantage of the dovetail in woodworking is that the joint stays tight as the wood expands and contracts with changes moisture content and temperature - not such an issue with plastics. I would love to see some heuristic strategies around which joints to use under which types of loads. In this video it looks like you are making longer rods which could see very different stress patterns depending on use. It would be interesting to hear which styles cope with which stress patterns best.

@SilvaDreams 2 месяца назад

Ironically moisture with 3D printing is still an issue with 3D printing but it's slightly different. It messes with the initial printing stage where as with wood dovetails actually take advantage of the shrinking effect to their advantage and makes an even tighter fit as it shrinks around the joint creating a stronger joint (it's normally done with green wood, kiln dried wood is fairly stable)

@bobeaston1389 2 месяца назад

This helped me so much. Using Dovetails to join a cup portion of a cup holder with the clip portion allowed me to print the clip in the correct orientation so the layer lines were perpendicular to the bending motion. Had to replace 13 cup holders with my new design incorporating the dovetail but they are strong AF now and these joins have completely opened up my mind for designing parts now.

Combining traditional woodworking with 3D printing to come up with something that's not limited by the way we'd machine the parts in wood is fun and it's a good challenge as well. I hope that people can find a use for them, and maybe come up with their own ideas that are better than these ones.

@NeedItMakeIt 2 месяца назад

I was originally going to do the testing for this video and I'm in the process of building a testing jig so that I can test in tension and compression. The issue I ran into is that some of these joints can be tested with loads perpendicular to the joint, but some not so much. I'd almost need a particular case and then create the connections to suit it the best and then test those. Thoughts on that?

@TheRealStructurer 2 месяца назад

@@NeedItMakeIt maybe I'm over simplifying it, but I would do the following: 1. Tension and compression from the ends and see where and how it breaks 2. Fix the ends and then press perpendicular on the joint from different sides. Depending on the joint type it could be more than two tests. 3. Based on results summary, see what joint is good for what scenarios Keep up the good work 👍

@NeedItMakeIt 2 месяца назад

@@TheRealStructurer Oh, you're speaking my language, I am a fan of all types of simplification. I'll have to do a bit of research on the typical testing jigs and make sure I have the right equipment. I have Two types of load cell at the moment, I have a crane scale, and I have a load cell with Digital readout as well intended for compression up to 4K lbs. I'd need to integrate them along with a scale to measure movement along side load. I've found that even my slo-mo camera mode isn't a high enough frame rate to capture the moment of failure, so I'll need to think about that.

@timlong7289 2 месяца назад

I love your scarfed and circular dovetail solutions, those look like awesome joints for different situations. I also like the idea of tapering along the length of the dovetail because they can get vaery stiff trying to put them together otherwise. I lot of very good information here, thank you. I find the classic mistake a lot of designers make is to not fillet the corners. I would say the smallest radius curve possible is around half the nozzle diameter, but I find in practice that the fillet radius shoudl be at least the nozzle diameter and it doesn't really hurt anything to go much higher, say 1mm as this eliminates any bulging at the vertices, which means you can have tight clearances everywhere else. On one of my designs (drawer units that slot together) I used a double-ended dovetail spline (sort of like a butterfly) that slides into slots on the drawer cabinets, and on that I made the fillet almost half the width of the dovetail, to it looks more like a "bone" shape, almost a figure-8 cross section but stretched in the middle. It was experimental but it worked really well in practice, easy to insert and remove yet holds the cabinbets together tightly and doesn't fall out. I wish I could post images here, I'd post a screen shot of the design, I hope my description makes sense.

@NeedItMakeIt 2 месяца назад

Yeah, each of them really has their own benefits, they're not really an apples to apples. I wanted to strength test them, but it doesn't work, I would have had to test them each in a different direction of loading. The most basic dovetail with the taper works really well and it's pretty straight forward, it's just better than the standard dovetail. I think in Woodworking to keep things simple we only had straight cut and relied on the glue to do the rest, it's simpler that way. Here we can do whatever we want. I agree with your note about the Rads, these connections were pretty small and I kept the rads really small too, but a little larger is better. Calibrating the filament helps as well to make sure you end up with the sizes you're supposed to, the slightest change in size on these connections makes a pretty big difference. It sounds like you're doing some large-scale work, are you on MW at all? What's your background, it seems like you have a background in Woodworking and Construction. Yeah the bone shape might be better in some ways, getting away from the sharp edges, what is the best shape, I wonder... now that's something that could be tested.

Dovetails are good for a lot of things because of how precisely and securely they can hold. If you are making removable or modular parts then even just a basic straight dovetail can be good because you only need a way to secure it against linear movement in the direction the dovetail is inserted since the dovetail itself prevents all other movements. Basically dovetails secure against all movements except their insertion movement, so your curved examples will be fine for all motions except rotation in that axis, which allows you to design the shape of the dovetail for the expected forces in your application. I have used dovetails for connecting the legs on a hexapod robot. The legs are made as their own removable system (to allow fast removal or replacement of legs) that can attach onto the body using dovetails. The dovetails don’t go all the way through (to help locate the parts vertically) and have a hole in them for passing wires through. I have two methods of locking them in the vertical direction, the first is just with some bolts normal to the attachment surface/plane, the second method is when the top plate of the robot is connected it prevents the dovetails from being able to lift out again so they are capped at the bottom and top and bolting the top plate down holds them tightly. I also have used dovetails for modular attachment points for cameras or sensors and hey have been held in place with the same methods I described above. An interesting idea that came to me whilst watching this was for a dovetail that works by twisting the parts together, basically a dovetail (probably better using two) that is swept along a circular path in the plane where the parts join.

Back when I did more Woodworking, we were using them non-stop, though they were always straight cut due to the limitation of our hand tools and machinery, it's nice to be able to remove those limits and have a bit more freedom. There are probably slightly better variations which work for plastics better than they would.... for wood as well. More curves and it would also depend on the plastics you're using and infill settings etc. I just finished some testing on GF filament for example and it is quite stiff and brittle, compared to PETG which is flexible and tough (With 100% infill) Would that dovetail be one set along a path on a portion of a sphere or a compound curve in order to achieve that result?

@conorstewart2214 2 месяца назад

@@NeedItMakeIt It would be a circular path, although it could maybe be applied to a sphere too. My idea was that you place the two parts lined up, end to end and twist (almost like a screwing motion) to slide the dovetail in.

@NeedItMakeIt 2 месяца назад

@@conorstewart2214 Yes, I can picture it now, that's a very interesting idea, printing orientation would be an issue with this style, I'd need to try to create one and see how it needs to be printed, I think standing up straight in the air with the faces of the connection horizonal would work. I have another video coming this weekend for a follow up, one I've finished that one I can look more closely at your idea.

Those dovetail joints are amazing! Wow!!! Maybe some will get incorporated into a slicer. I just recently discovered the dovetail in Bambu studio and it’s very easy to us and is far superior to other ways I have employed to joining parts.

@MrFranklitalien 2 месяца назад

@@NeedItMakeIt I've been brainstorming a mostly printed 3d printer with some friends, like the snappy v3, only instead of using snap fits or screws I'd like to see if I can do it with mostly keyed wood joints and zip ties; hoping to drive the cost down below 200$US as a benchmark. CoreXY geometry would be great for building on top of the base architecture (might integrate arms and wheels later down the road as part of the NASA autoreplicant robot program)

@@MrFranklitalien Perfect! If you can wait for a little less than 1 week, I will have the follow up video and I will try to think of how it could work well for your application as well. I love your idea BTW, a fully 3D printed printer... minus some non-printable stuff would be very cool and I'd love to try it on the channel when you get to a point that you're ready to share it. So far the ABSGF25 from QIDI is the most rigid filament I've tried, next would be PC and then PETG-CF and Hyper PLA are tied. I'd imagine that a rigid material is important for your application.

Personally I prefer drawing a sketch with a closed polygon with the total tolerance and extruding/sweeping that. But it's a fidgety process

@NeedItMakeIt 2 месяца назад

I'm working on a better way to present these so that I can convey the info better and focus on the main points. I'm shooting for a live-action and I'll cut out the bits with no action. Capturing the screen and than narrating it works fine, but it's not as good as explaining while doing. Thanks for your support!

@NeedItMakeIt 2 месяца назад

That's a good option too! I've used both methods as well, there is another option too, and that's to do all of the work to one part and then use that as your cutting tool, I don't know that it saves anything, it's just a bit different and I've used it with success as well. I'll have to put some thought into what might be the absolute best and simplest method.

@jakobhansen1396 2 месяца назад

@@NeedItMakeIt the sketch with tolerances (either method) makes it more logical to use a global tolerance value. If a global tolerance doesn't apply to all distances, then the shown method is easier to understand

@NeedItMakeIt 2 месяца назад

@@jakobhansen1396 I agree, I think it's best to get as much as possible in the sketch and set parameters as well.

Great video, love the different joints. Would be good to see the basic dovetail at 0.04 offset. Your fusion 360 skills are awesome

@NeedItMakeIt 2 месяца назад

That's great! Yeah, I could certainly try the 0.04; my concern with that connection is that it was hard to put together, originally I had the parts much larger, but to be able to 3D print all of them and have them on camera, I shrunk them down a bit. I think it would have been possible and could have worked fine. The taper is still better, but the standard dovetail works too, it really depends on what you're using them for. Thanks for the support, I enjoy using Fusion, it can do just about everything I need, it doesn't like meshes, that's one of my main complaints, it's all good and we can find ways to work around it.

I've been using a dowel pin system just to keep things lined up where they need to be. This seems a more elegant solution.

@NeedItMakeIt 2 месяца назад

I guess it depends on what you're building, I find that holes need to have a peaked top so that they print well and don't collapse in too much on those top layers, I suppose the dowel can be whatever shape you like though, it makes sense to do a triangular dowel for 3D printing and you get an auto-peak and a flat surface. When I worked building furniture, I must have inserted thousands and thousands of dowels, they work especially well with glue.

@joshcarter-com 2 месяца назад

Quick note for other viewers: don’t orient dovetails in the Z axis where tension will get put across layer boundaries. Do it like this video, where the dovetail is primarily on the XY plane. In Fusion 360 it makes me nuts that there’s not a simple operation for “this part mates to that part with [x] clearance.” Instead you have to model the clearances or do a bunch of push/pull operations. I tend to do the former because it keeps the dimensions in the sketches vs. in the dialog boxes of push/pull operations. But the latter is quicker. Really excellent video-instant subscribe from me!
