Making two fins with these huge chamfers doesn't really constrain them vertically though. They will just slide out if pushed from the top or bottom. You might want to angle them 45 deg to each other which then works perfectly with printing on the chamfered corner like you showed in a previous video. edit: also changes the layer direction to a better angle so you don't risk breaking them right in plane

That is only feasible if there is the area to support them. Generally features like these would be made smaller and be on the outer edge of an electrical enclosure. It is also ideal to chamfer the inner edge of the slot as well so that part is constrained in both Axis.

Yeah.. as a mechanical engineer this is just bad design, there's a reason we just use 3-pin locating for fixtures. Or just use locking methods we use in Wood, like Dovetails. We actually just avoid pins when unecessary often for assemblies like in end products. Screw holes should be designed to locate the part to function as required, better to just use screws, nuts, and threaded holes when possible. For 3d printed parts if you want a thread that's not printed too, you can just have a slot in the side of your part, insert a square nut, and boom you have a metal thread.

I like your approach to trying to get people to focus on more approaches. With this, there are many approaches. Majority of the time pins are not the approach as they snap easy on 3d prints. Usually for me, slide (dovetail), or snap fits like cutting the edge and extruding the others but with a tight tolerance works best. 0 post processing and if you put a ridge on the edge then the two parts connect and break away in a very satisfying way. It does take design practice though. Being able to just follow your edges does in some cases improve the chances that you have a proper fit.

Interesting alternatives to typical metal dowel pin alignment 👍. Actually the pins need not be round to start with, if to print hexagonal pins laying down it should print fine without support. You can also make the length a little undersized. Chamfer on end faces both on holes and pins should help as well. Then it is just inserting these pins with a drop of cyanoacrylate(aka superglue), is all that is needed. Should makeup for a much stronger and durable part with least amount of overhead interms of effort/time. The approach, does not sacrifice extra space, or need to accomodate new design requiremts for things such as slots. It is also Poka-Yoke. Just some thoughts ....

You can also print them lying down. What may increase the print time there is that the normal slicer settings will often require multiple layers on the bottom to be 100% filled.

I think it should be noted that fins are nice, but they provide a very large interface surface between fin and hole, which reduces robustness as slight variations in any part of the fin hole make the entire part no longer fit. By definition robustness is the tolerance of something to variation, and in a manufacturing engineering context where large runs are expected, features like this would be avoided due to how much variation would impact final work. A good solution to this problem is to remove some more material from the fin holes so that the fins only contact the holes at a set number of places, like 2 or 3 max
@ckobrien
Жыл бұрын
I realized that solution is a bit confusing, the important part is that rather than making a full fin surface interface with a surface of equal size, change the interface to only physically touch the fin at a couple of places and have small air gaps elsewhere. Constraints remain the same, while tolerance to variation is much more kind

Use 3 if you want to constrain it to only fit one way. Making it possible to assemble 4 different ways might slow down manufacturing a tiny bit, but it speeds assembly. This is all if something else is holding them in position, and the features are just for alignment.

Plus as you stated earlier in the video, dont print unnecessary features. You should only print 1 fin because it will fully constrain the part. Finally you gan fin rigidity by printing vertically. But you loose surgace finish and stength for the rest of the part. Always a balance, cant get something for nothing.

You could literally see how the fins DID NOT align the two blocks together.... At least a good 1 or 2mm out from each other 😂 Steel dowel pins are very cheap, accessible, and are very accurate. They also don't have the risk of shear like printed pins do like you shown in the video. All you need to do is make one part with holes that have an interference fit, and the other to have holes that have a close clearance fit. You don't need to reinvent the wheel. There's a reason that method is used in traditional injection moulding equipment.... BECAUSE IT WORKS AND IS REPEATABLE!!! I get the drive to think differently, but you need to also consider the fact that if something isn't broken, it likely doesn't need fixing... Also, 3D printing is really only suitable for at most low quantity batch production parts. If you're doing 10's of thousands of parts, you'd be best to just go down the injection moulding route... You'd get parts far quicker, more robust, more accurate, nicer finish, and probably very similar in cost even with mould tooling design and manufacture included.

Now we just need libraries of predesigned features like those shown here for mating parts, as well as simple parameters to size them and apply both in a single operation. Think of it as an extension of the Hole function, where you create the hole and attendant countersink all in a single step. One click should let you choose a mating style from every reasonably strong possibility and be able to set in place on both sides of the mating as features added to the design. This should even include splitting a model into two parts for assembly afterward by simply positioning the mating type and locations desired as part of the split process, such as locating them within a plane being used for the split. A simple see through view can let you see and position the desired new features before committing the split to render the then separate parts.

Pins work fine if your using them as an alignment for walls or something that is going to be superglued together. This also helps make said model stronger when gluing together as there is now more surface area for the glue to bind to and less likely the model will come apart. I usually use notches or some sort of means to align my designs together, usually corners of a wall of a model building. This makes thing a little stronger and easier to put together, while making the model itself easier and faster to print, since its all laid out flat on the bed. Due to printing inaccuracies that happen, I always error on the larger side for any holes, usually about .5mm bigger in X/Y then the notch/pin/whatever is. This makes sure that the designed alignment piece WILL fit in the hole, even if it has a little bit of wiggle room, since prints can vary from print to print even on the same machine.

Often the easier is better than fewer parts. Also pushing pin a into hole b is easier than screws. But screws are better for securing mated parts where there is no room to put a pin in hole connector.

These pin chamfers are a construction mistake and don't make sense, because now you have something called a "Doppelpassung" in german (I couldn't find an english word for it). Basically you have two faces that act as a fit, which is impossible if you have any type of tolerance. Plastics are flexible so it might work in this case but you should at least mention it.

does not work as it only limits in one dimension as seen in the NOT fitting last shot

Ok, here is my amateur tip of the day. Make just holes, and use the filament of the 3d printer as the mating pin. Also, the video is showing that 4 pins is bad, and then the second solution is to drop it to 2 pin, doesn't make any sense.

the chapfer idea is great... the other ones are not practical for parts that are reusable, i mean the parts that use alignment, the chapfer is strong, provide alignment and is strong and wont catch.

Great content, but if you want accuracy, you dont use FDM for mass production. It's weak and takes forever. For a one time prints, you could use piece of wire or even pirchase small guide pins that come in useful.

2 pins with the chamfer, perfect. No need to go further with these fins. Just as breakable as pins

What are advantages of using expensive software like 360 over something free, like Blender?
@TinaDanielsson
Жыл бұрын
Fusion 360 and Blender are two different types of software so you could not use one instead of the other once you start doing more advanced modeling. I'm really over simplifying here but it's a bit like comparing making a technical drawing with a ruler or by freehand. F360 is a CAD software and it is actually free for personal use. So is OnShape which is a major contender. FreeCAD is a completly free alternative but it has a different workflow and can be difficult to get used to. I've given up in frustration several times 😅 Blender is more used for "artistic" purposes and some comparable softwares are Unity and Maya.

The time it would take to print that part horizontal then print that part vertical is drastic. Printing that part vertical would drastically increase the print time of that part.

when mass printing, you can stack a lot more on the plate in a vertical orientation, requiring much less human time to set up and clean off the machine (with the added benefit of layer line orientation.) attending to the machine once per shift vs 7 times per shift.

Print time is an irrelevant metric. That is point of print farms. Large parallelization of automated production so that the project takes as long with printing as with any other process.

@@slant3d print time correlates with rent and machine amortization costs. True for any machine. Just because a farm has many of them doesn't mean it doesn't matter. Sure, you can charge 1000$ per print on one machine even if it takes 1 hour, but then you're in luxury territory and no longer commodity manufacturing and no longer makes sense with the rest of marketing messaging.

@@slant3d how is print time an irrelevant metric? Especially for print farms lol. When you have hundreds of printers operating all making the same “mass production” design, 1 hour saved per print stacks. Your yield is drastically increased in the same amount of time, your utility costs go down bc you saved 1 hour per print per machine (less power needed to run the printers for less time) you also reduce the wear on the machines thus saving accumulative maintenance/repair costs. You also make more money by finishing that production wave sooner allowing you to make money sooner on the next designs. Why do you think old school factories and assembly lines focused on the literal amount of foot steps workers had to take, cutting out seconds and fractions of seconds anywhere they could? Print times are irrelevant to hobbyists printing a couple parts a month. I’m not even mad at the video. It’s a fair idea in specific use cases, but when your parts didn’t even align properly I had to come check the comments. If you are going to talk about quality and accuracy at least reprint the demo to align correctly for the video lmao. Not saying you don’t have the skill. Idk what it was, design error, printer error, printer calibration, etc. but to hype up the mass production time saved, stability, accuracy, print focused design choices, etc. and then make comments like print time is an irrelevant metric while using the scenario where print time matters most as your arguing point for its irrelevance is smooth brain and ultimately null and void if your outcome doesn’t even align properly 😆 I’ll check out some more of your videos and give you a fair shake (this is my first) but just one man’s opinion, do better man. Don’t argue with commenters on YOUR videos giving you play time (regardless if they’re right or wrong) about petty shit and then not even have the parts align dog. Post sand that shit, hide the misalignment with a better camera angle, something. You clearly have more skill than that outcome. I hope to see it in your other videos

printing pins separately might be another good alternative.
