One feature of the cup handle you are ignoring and is even more important than design and that is to create a handle that has good mass separation from the hot liquid part of the cup. This is to prevent, slow or at least cool those parts of the handle that are in direct contact with the container to eliminate heat creep. I like your last design but it poses very poor structure near the container part and will introduce a hot surface that will burn the most sensitive skin on your fingers, that being the back of them. Consideration for heat dissipation should be a critical design feature when coming up with the new upgraded handle to ensure comfort and in this day and age the need to print warning labels for the ignorant among us that are just looking for a reason to sue someone! OK so that last part is a bit hyperbolic but then again depending on the case use it should at least be considered. I am really enjoying the creative dialog this is bringing to the industry, keep us thinking, innovating and improving! Awesome new series!

As someone who actually has multiple degrees in design fields (architecture, art history, and industrial engineering) and also has been 3D printing at home since 2015 (Used lithographic printing machines back in 2001-2004 for undergrad but that doesn't count in my mind), there are far too many people that get a 3D printer and watch a few youtube tutorials on Fusion 360 and then think they understand the basis for the actual design. The old adage of form follows function is meant to be about the user, not the tool that makes the item. As such, this entire video was developed under a completely faulty pretense of "mass production 3D printing." Nothing that is truly mass-produced would be designed based on the tooling requirements of 3D printing as it is just not economical or logical to allow a slow, albeit useful, means of production to dictate production. Instead, mass production implies meeting demand or creating a large supply at a minimal cost. In both cases, the design would be dictated by customer wants and then (shudder to type) value-engineered down to a price point that can be mass-produced. The end result with the "optimized" clip handle does nothing to innovate or move the design or use of the mug forward and actually alienates people to only hold with a single hand. The design does not solve a known issue in the customer base such as people with physical disabilities and actually reduces options for holding with limited grip strength and finger mobility. Lastly, the design, if actually meant to be mass-produced, would still require the development of a three-piece mold (or more likely a two-piece mold with a removable piston for the inside of the cup). As a result, the cup is not easier to produce in large quantities, does not improve user experience, and does not open the product to a previously unavailable customer base. Instead, the design helps justify the use of a production system (desktop-sized, FDM 3D printers) that was never meant or developed for the type of production this video proposes to support. 3D printing has its place - impossible to produce and complex geometries, small-batch products that would otherwise not justify tooling costs and time, rapid prototyping/design iteration, and/or access to production methods for the masses. Waxing poetically about "space-age" design ideas and then not actually pursuing anything about good design as a medium for future-proofing or improving on historical design paradigms ain't it, sorry.

@@alkaliaurange Nah, the video is badly missing an important point: don't reinvent the wheel just for the sake of reinventing the wheel when there already exist a proper wheel design for the scenario. The video premise is circular handle is bad on 3D printing production. Which is valid, and no, we not going to stuck into mug and handle, as like you said, it just to illustrate a point. However, the proper solution is not to immediately jump into designing weird, compromising handles just because it can be printed with 3d printing better than original circular handle while ignoring other aspects of handle designs and functions like many other commenters pointed out. In the end, his solutions only works well for 1 aspect which is 3d printable, but not working well as its main function: a handle. Again, this is not about mug and handle, you can apply this when trying to create new "revolutionary" designs and simply ignoring or forgetting what the main function it should have first and foremost. What should've been done is looking at regular alternatives first if it can meet the original constraint (i.e. 3d printing). The L shaped handle fit that criteria and easily 3d printable, so we can just go with it and done. No spending R&D for weird handle that not even functioning as well as the already exist and simpler L handle. And even can go logically further as if the circular design is bad, use the wedge design instead of full circle for the handle. Make the handle more straights instead of vertically curved that is the biggest weakness of 3d printing. Add more thickness to the handle part to increase strength while still keeping it a comfortable size to grip. And we just design a new handle that is 3d printable and still function well as handle as we don't need to alter the very basic principle in the first place. That is how this video should be. If you need to alter a design, don't jump straight into reinventing the wheel with radical ideas that you don't even think how it will affect other functionality that you so much tunnel visioned on. What you need to do is to look for existing proven alternatives that already solved your problem first, and if you do need to make your own design, better to make it an iteration of existing proven principles instead of going completely radical because they are proven for many reasons.

This video could be a very good video if framed only as proposing better option for 3D printable handles. However, instead it dismisses any other manufacturing technique as outdated and thus the handle design as outdated. The reality is that while ceramics have been around for thousands of years, they still remain the best option for many use cases. Even for plastics alone, injection molding is a superior technique for many use cases, especially at high volume where the price of molds (which absolutely can create that ball handle design) are economical. Of course for smaller scale manufacturing than it'd take to make a mold cost effective as well as for prototyping, 3D printing wins out, which means scale of production would likely be a very important factor in design. Basically, this video does exactly what it tells the viewer to not do and puts a round peg in a square hole. And that transforms it from a truly great video to a truly infuriating one to watch.

See, the biggest issue with all of this is that they don't allow for a wrapping motion where you actually grab the cup or mug around the outside. All the handles are designed as just that, solely a handle. But the ring handle is not just for holding onto on it's own, it provides support for the hand (think like a pop socket on a phone) when grasping the whole object as well. You can see this by the way you grasp many of the cups you've created when showing off the handle, you have to hold in in a very uncomfortable position because of the handle shape taking up so much space and being connected all the way down the cup.

Most of those designs rely on friction for keeping the mug up, forcing you to hold much tighter than a conventional handle, which would get even harder once the cup was filled with liquid (and would become impossible for someone with limited strength/dexterity like children or someone with arthritis). A good way to test weaknesses like this is to try using the cup with your non-dominant hand coated in oil as it simulates low dexterity use without needing to gather up testers of different demographics (although getting those testers later on in the design process is necessary, just not at the initial stage where your rapidly itterating like this).

If you actually look at the handles of "stone age" mugs, they are shaped more like half of a heart shape and the 2 points where the handle connects to the mug have chamfers built into them, I suspect this would remove the need for extra supports when 3D printing. Maybe the reason the handle design hasn't changed, is because it actually works if done correctly.

My personal solutions would be to print a ladle style handle and then use hot air and a buck to soften and form the handle to a classic D ring shape. This is similar to the stone age process of steam bending wood in order to make curvy shapes without sacraficing structural integrity. I wouldn't be too quick to dismiss stone age technology. stone age tech is often very thoughtful and creative and novel. The clovis spear head for example with its central fluting is thought to have been designed to attach a heavier mass spear head to a thinner shaft. Thus increasing the energy unloaded on impact while still allowing the thiner dart to flex and maintain its course.

Brutalism is, I think rightly, derided as an ugly, depressing style that seems to be dying out, thankfully. The thing is that we like nice things. We like things that look pleasing or that are beautiful. There is something that is just nice about that traditional ring-style mug handle that the alternatives, at least as shown, lack. From this perspective, that handle design hasn't been in use for thousands of years just because that's the way we've always made and designed them, but because we like the shape of it. It feels good in our hands, and it offers a lot of functionality in a simple design. It may not be the best fit for 3d-printing, but I don't think you did the alternatives that are better fits any favors by not giving them a more aesthetic pass in your design process. As for the ring handle, you can make it more manufacturable on 3d printers by employing some of the features from the other designs you showed. Support the bottom of the handle like you did in the first design, maybe give it some curve to make it more comfortable on any fingers that part may rest on with use. Turn the circle into an ellipse and angle it towards the cup. This will help minimize the shallow overhangs you get with a circle and also make it more ergonomic by better matching the shape your fingers make while partially closed. You still have a part of the print where stringing, blobbing, and print failures are a risk, but you can't design every part to avoid those and it's a much more manageable risk than the overhangs and supports. (And to be honest, if you're printer isn't tuned to prevent the stringing and blobbing, it's probably not ready to be used for mass manufacture anyway.) Anyway, those are my thoughts on this, for what it's worth. I'm not a product designer, and the most engineer thing about me is that I know some physics and my degree program was part of the college of engineering at my university. I do understand art, aesthetics, and how important they can be, and I think your alternatives do miss the mark there. While I'm here, I know you did a video on making snaps and designing them for 3d printing, I was wonder if you could do the same for keying designs for assembly. There are times where you don't want a snap (permanent assembly or something that's supposed to come apart easily) and wondered if you have any tips there.

I agree. The "Traditional" design presented really doesn't look like a real coffee cup handle. It is essentially an exaggerated stereotype, which sort of makes the "Not this" part of the design evaluation really more of a straw man than a serious comparator. In particular, the rounded bottom of the handle with concave up toward the body of the cup can be cured with a much less radical design. I am not bothered by the radical alternatives. New forms can stand or fall on their own and the ease of experimentation IS one of the great things about 3dp. I am bothered by the presentation that assumes that only radical departures from the time-honored form is worth noting. There are reasons besides constructability in clay that we like the traditional handle, including the ways people like to use them. I have to say though, even as a lefty who would be the odd man out, I think I like the asymmetrical design 😊
@ianbelletti6241 Жыл бұрын
Even without talking about dexterity and aesthetics, the design has one simple task. It has to work effectively with the body to control the load. For example, although the ball handle can work, you actually have less control of the load and more strain on the body when in use as well as the fact that it forces you to hold it in a way that contradicts how the body operates. As far as a handle that's meant for hanging as opposed to holding by hand or is part of a machine interchangeable connection the ball handle would work just fine. All the handles shown have the same simplistic problems of not being effective handles for human use under most circumstances. The core is to know what purpose your handle has before designing it. Certain features work better as tool connection points. Others work if it's just meant for hanging or initial grab of the object and it's not meant as a human interface control surface. The pinch handle, for example, has been around for a long time but is rarely used because it's a strain on the grip to hold and is really only effective for very light loads.

1. Just make the bottom of the hoop at a printable angle. 2. You could print it on its side with the handle on the print bed. You just need to find a way to integrate flat surfaces so there is sufficient contact. 3. Print two flat parts on the top and bottom and connect them with a pillar 4. Have the cup on its side with the handle tangential to that side so it lays flat on the print bed

The traditional design is horrible for FDM, fully agree there. But it's still pretty decent for SLS. No need to go all Bauhaus on the design if you pick a different process. Plus for FDM, there are still workarounds to have a more traditional handle design without weird scraggly overhangs. For example, if you open the handle instead of making it a closed ring, and bring it all the way down to the built plate, you solve a lot of issues without deviating too far from user expectations. Kind of like your ladle handle design, but with a hook.

This video highlights what I have been saying for years: that there is a HUGE difference between designing something and engineering it. When I hear that someone is a "designer" what this tells me is that they work strictly around the aesthetics but when I hear that they are an "engineer" I see them focusing on the functionality of both construction and end use. Too many companies focus on designing items today and this has lead to things that are pretty but poorly engineered. When design is the primary goal there are too many sacrifices made. Engineering has this same issue however the sacrifices there are usually in the aesthetics. being a function over form type of guy this works well for me. I don't want any of my money being used to 'prettify" something if it means that it will be poorly engineered.

As both an engineer and industrial designer I can tell you that this couldn't be further from the truth. Industrial design always keeps the manufacturing process in mind. Some products are more like artistic sculptures than good industrial design however. I've seen a pepper mill yesterday that was in the shape of a bottle - that's just bad design at this point. Not only is this object pretending to be something that it isn't, there is just no indication of how to use it. In my experience engineers are often very focused on the process but don't really have an eye for the users needs. The problem with the term designer is that there is no protected job title as there is for engineers, at least in Germany that is. Everybody can call themselves a designer without proper education in the field.

@@randoguy7488 I guess then it all comes down to how we think of it. To me, the cup would be engineered with the handle as a functional addition whereas the designer would focus on the shape and making it look a certain way. Perhaps there are too many definitions for the two terms but when I went to school engineering was all about the structure and physical properties whereas design was all about aethetics and "art". Using your example, the engineer would say 'This cup needs something for me to better grip it with that will also prevent me from burning my hand when I pick it up". The designer would say "this cup needs something that I can hold the cup with but it should look nice and follow the lines of my hand. It'd be good if it also had a nice organic flow to it". Possibly there is a little bit of each in one another and maybe, from my own observances, people often drift far too far over into one camp or the other. But again, in my experience, a designer doesn't take functionality into mind. If they did we would not wind up with so many stupid products that serve no real purpose other than to look nice "over there". And if more engineers were listened to instead of being pushed aside for design we'd have products that worked VERY well with no functionality compromises. A designer would take out the headphone jack from a phone because it looks better whereas an engineer would find a way to keep it there. Just my 2 cents.

Some interesting and valid points, but you completely missed two of the most important reasons to use a loop-type handle: security and leverage. Security: by putting your fingers through the loop and closing them, you create two interlocking rings that require *very* little force to maintain. Leverage: Your top finger in the loop becomes a fulcrum, with the weight of the cup pressing against the back of the rest of your fingers. This--again--makes for a very stable and secure platform that requires *very* little force to maintain. Rather than a small loop at the top of the cup, I would make as long a loop as possible that tapers down to the base of the cup *and* tapers up to the top of the loop. (Think half a heart-shape.) This would be easy to print and offer good security and leverage. As well, by making a loop large enough for multiple fingers, the user can grip the loop instead of letting the cup rest against the back of the fingers, which prevents discomfort if the cup is filled with a hot liquid. As well, you didn't talk about how multiple cups might work together. If you include an inset on the bottom of each, they can naturally stack together for a more desirable design. (Bonus points if you add nubs & channels so they can be rotated to lock together.) Cheers!

One tip to everyone about 3D printing (on a small scale) and such while we are here.. you wouldn't want to do this for mass production because it involves making extra parts and 3d printing just isn't a good technology for making cups with, but always remember that you can print multiple parts and assemble them. This is a good example of a case where you could print the loop on its side and then attach it to the side of the cup section with something like fasteners or slots. It's tempting to want to print a part in one go, but sometimes that isn't the best solution.

Now those giants are trying to play catch-up and having to completely retool their business models and distribution chains in order to prevent bleeding off more sales. They all believed that a car is just four wheels and a power unit that gets people from A to B. As such they produced cars without inspiration or understanding of what the public was asking for (or with a lack of caring). A bunch of start-ups and other car companies that accepted EVs as a segment customers were demanding actually went out and tried to find out what was wrong with the current car and driving experience. Then they went back and they designed solutions to those problems regardless of the production methods available to them.

Note - Im a HUGE fan of 3D printing and have my own 3D print design start up for constructor bricks, where democratizing the design makes sense. Still I prefer to have a holistic view of these things.

A classic case of an engine creating a problem and then solving it. Just make the normal handle but where the bottom of the handle begins connected to the cylinder that way it doesn’t require supports. Is there a 3d printing process that make food safe items?

Great thinking all over, thanks! Only your last handle limits it to right handed users. Bit odd for the left users.

Literally no reason to redesign it. There are so many more factors than manufacturing. For example, the coffee mug handle is usable with very little gripping, meaning someone with limited motor control in their hands could probably use it. Stop being tech bro

one easy solution that keeps the benefits of the ring or C-shaped handle: just make it a little more of an S-curve so that its not as aggressive of an angle for the printer to try to do and it has the same benefits of the fin design plus the benefits of the c-shape

Yiu have some good ideas and insights, but when you say your alternatice designs wouldn't be manufacturable buy means other than printing, you're just not correct. Any if those designs are easily moldable via injection molding. I appreciate your points and agree with them, especially in the realm of 3d printing, but please respect other manufacturing techniques as well.

The ball handle cannot be molded for the reasons discussed in the video

@@slant3d I come from an injection molding and die casting background. Every design in this video would absolutely be able to be injection molded - with ease. I 3d print all the time and love the technology, but it's not the be all and end all for production manufacturing. Also see @ReedArnold comment below. Good insights also. Again, I like your videos and you have great points. Thanks for your efforts.

Curious how did you print the bottom of the cup? Was that a horizontal overhang? Very interesting video, thank you for taking the time to put this together!
@andybrice2711 Жыл бұрын
No overhangs, it's just a fillet with the bottom cut off slightly.

Show me where i can grab the body of a cup, sliding my fingers through, like i can with regular cup? Also the indented fin can sustain a hole through it, bringing you to square one

Try holding that cup with one finger, or try holding multiple of those cups at a time, the loop handle serves a very important function that the ball cannot.
