It’s true. There are some simple things that could be done to improve the Hovalin. Use a tailpiece and bridge instead of printing them on, that’s too much mass on the top plate, and modify the design to allow the plates more freedom of movement. Even if they’re three parts they could glue or weld them, but the fittings add nodes to the plates... At any rate, thanks! I hope you build a ModFiddle and do a sound comparison with your instrument!!

Awesome! I have so many questions. Is there software that you're using to predict sound quality, or changes in quality with changes in material and design? Will this work as designed with woodfill filament? I have a luthier friend from whom I can get parts, so I'm going to get some pegs and parts locally, and begin printing this weekend. Will a square rod affect acoustic quality compared to the round one? A square rod is stronger, so can be made smaller. Also, it seems to me that using it as a truss rod can offset potential warping, is there any potential downside to adding in adjustable tension across the entire rod length? Do you have a forum on your website? Discourse is phenomenally easy to moderate and use, and it'd be a great resource. Thank you for this!

Josh Rowe, these are great questions! Let me give quick answers and you can shoot me an email David@openfabpdx.com if you want to talk more. First, no forum on my site but I have a google group here: groups.google.com/forum/m/#!forum/fffiddlers and check out the forum at violinmakers.org Woodfill would be fine but may not improve quality. Carbon fiber filled PLA from ProtoPasta does, though. I would be interested to see what woodfill sounds like! Traditional pegs don’t work as designed, but I’m working on a pegbox design that accepts traditional pegs. Email me for info. Interesting thought regarding a square tube. Hovalin used to use one but they moved away from it. Smaller would be better. And yes, adjustable tension would be really good - you could tune the scoop on the fingerboard. A designer made such a thing for a derivative of my F-F-Fiddle a few years back. Join the google group to learn more about his work. Thanks for your great questions!!

Today, carbon fiber violins, even the ones costing around $5000, use a wooden bridge and soundpost. It would be great if you could squirt something out of plastic that sounds like a Stradivarius though.

Also, my printer has problems with layer shifts at the top half of the print.

The CAD-generated bridge sounds to me as if you were using a mute on a normal bridge. Do you have to be careful with choice of plastic and angle of print to stop parts delaminating? And does the fingerboard wear down over time? I imagine normal PLA wouldn't last as well as a normal wooden fingerboard - or be as smooth.Thanks for sharing.
@openfabpdx

Great questions. I haven't had any issues with delamination, but using a carbon fiber reinforced material is much better. PLA is nice and stiff, but stiffer is better. Using a carbon fiber PLA, the bridge still needs to be printed almost entirely solid or else it will sag over time. For the fingerboard I would say yes, it probably does wear faster than ebony (which is the wood typically used for fingerboards). That said, I have not had any issues with wear. Even the hardanger fiddle with a wound D string, which is very abrasive, is still OK after a couple years of regular use. And it can certainly be sanded to be as smooth, but I would argue that isn't actually necessary. I usually use a scraper and then 220 grit sanding block and my customers are happy so far. 🙂

Yes in theory there may be a small change without a chin rest, but I don't think we would hear a difference. And great question about wood filament. Most wood filaments have rather poor mechanical qualities. They use low-quality wood fibers that are inconsistent in size, and when wood is shredded/powdered for use in filament it loses the mechanical structure that makes it a marvelous material! Wood filaments are OK for aesthetic purposes, but the mechanical performance is low. What does improve the sound is a carbon fiber filled filament, which accomplishes the kind of gains that you are imagining for wood filaments.

hmm, those peak resonance frequencies could come down quite a bit. I think that wood naturally dampens the high frequencies due to its porousness. I Imagine that a heavier body might help lower the resonance frequencies but it could also lower the volume. I wonder what increasing the thickness just under the bridge would do... Just did some googling to look at densities of pla and wood and I can say for sure that wood does not get its advantage through higher density. pla is at a disadvantage here. what I'm wondering is if sound travels better along the grain than it does against it and what that would mean when you're trying to work with a material that doesn't have that kind of bias. Maybe it doesn't matter as much as I'm imagining. But for sure wood get's its advantages by being less dense (more easily moved by the strings), stiff but only along the grain, and it absorbs high frequencies (maybe more so against the grain than along). So here's an idea, you could try creating a violin that's structurally reinforced lengthwise by basically having rows of thick and thin sections but using less material than you did in this video, not sure if the inside would need to remain smooth or not (im not sure how much internal reflections matter), and then if the high frequencies were still a problem you could find a material to put in between the bridge and the body that rolls off anything above 4-8 khz.

Carbon fiber violins can be made as loud, or louder, and have an extremely wide spread of frequencies, than wood, because you can make the CF vibrating plates extremely thin compared to wood, while making it thick elsewhere in order to give it that "woodsy" sound.

The primary trouble with the Hovalin's built-in bridge is that it is very large. You are correct that a printed in place bridge is not necessarily worse than separate. On the Modular Fiddle the sound box is printed as one part. On the Hovalin it is printed in several sections that are joined together, but not in the traditional manner. It is instead split perpendicular to the body into box sections, such that the top and bottom plates are not continuous material.

@@openfabpdx Thanks again. I noticed that the bridges seemed to have a 'central stalk' rather like a mushroom, and I wondered if a separate 'stalk' for each string would be more effective. That way, the vibrations from each string could enter the sound box before being 'mixed' in the bridge. Also I suspect that the construction of the bridge by itself could significantly effect what is transmitted to the sound box. What are your thoughts?
@openfabpdx
5 жыл бұрын
Indeed, I agree! The bridge construction has a huge impact on the sound of the instrument. Between the red and the green Modular Fiddles shown in this video, the only difference is the bridge. I have also thought that it would be interesting to have separate stalks, as you describe, such that you could tune each stalk for certain resonant frequencies. Thus it could amplify desired frequencies of each string, and could restrict vibrations at unpleasant frequencies. It's crazy how complex the system of a violin is. If we separated out the string resonances as described, then it's possible you would get many fewer overtones in the instrument as each string excites the other strings as well as the after length sections of the strings (between bridge and tailpiece). That's part of what I love about the Modular Fiddle -- testing ideas such as this one is very easy! Any part, especially the body and bridge, can be easily replaced.

Just looking at the Hovalin design, I feel like its biggest shortcoming is that really fat printed-on bridge. I'm guessing structural strength was a reason they made it so big, but it also seems like it would make energy transfer really inefficient. By any chance, is there a high level of infill inside that printed-on bridge? Seems like that would absorb a lot of energy. Also curious how they handle things like the bass bar and sound post. The Hovalin sounds very much like a violin that doesn't even have a sound post or a bass bar. For that matter how are you doing it? Your optimized bridge seemed to have the opposite effect over in that its stiffness made it respond almost too quickly with no damping at all, especially at the higher frequencies. Wood having some inherent softness means there's also some damping as a result. I do feel like when you have limited control over the properties of the material, you have to mess a bit with the design to get similar vibration modes and energy transfer as well as volume of the resonating body.
@openfabpdx

Yes you are spot on here. I believe that the Hovalin does have a soundpost and bass bar, but I don't know for sure. Yes, the large bridge that is integrated with the top plate, as well as the integrated tailpiece, has a large dampening effect on the Hovalin. Yes -- a traditional bridge acts as a mechanical filter -- amplifying good frequencies while damping out less pleasant frequencies. The material has a lot of influence, but the geometry has perhaps even more. The Modular Fiddle has both bass bar and soundpost that are printed with the body, so all of the body is a single print. The soundpost is about the size of a standard wooden soundpost, and the bass bar in the latest design is similar in geometry to a traditional bass bar, where it tapers in thickness towards either end of the instrument. The printed-in-place soundpost, however, cannot put the plates in tension as it does, or can, in traditional construction. I am still looking for luthiers that would like to build up an instrument and place the soundpost manually. We could find a better position, and I would be very curious to hear any difference.

A lot of luthiers believe that the old Cremonese masters were using all the same criteria that they do when selecting materials, when their own journals really say it was down to using what was available and only relying on a few key principles about the materials and using things like using both hard and soft woods for example. And most of the art was down to design and craftsmanship. And yeah, all of them experimented and learned from other instruments they made and played around with tiny variations here and there and if they had a long enough career, they eventually settled on a certain pattern that worked for them. I'm sure that if they had other materials available to them like we have today, they'd absolutely be experimenting with them. Modern luthiers are actually far more wedded to tradition than the old masters ever were. I'd believe that the tensioning effect of an inserted sound post might help -- it probably results in the actual contact patch serving as a vibrational node. I'm aware of some adjustable sound posts, but they are ridiculously expensive... however they use a screw mechanism to lengthen/shorten the post and magnets for alignment/positioning. I feel like you could 3d print a simple mechanism like that, but I'm not sure how much it would really help. I'd also be curious how much of a difference you can see from messing around with various other body designs. Back in the 1930's Mysore Chowdiah built a 19-string violin that had 12 sympathetic strings laid across the body tuned to the chromatic scale and 7 main strings set up as 3 pairs (much like the paired-up strings in a mandolin) plus a 4th (G) left alone, and it sounded completely horrid, but if nothing else, it was really powerful, which was his real goal. I would also wager that the bad timbre had more to do with the pairing than the sympathetic strings because his usual 7-string violin also sounded pretty horrible. One that I heard in person recently was an old Julius Zoller violin ca. 1945. It's a completely bizarre look with its lack of C-bouts, sympathetic string under the fingerboard and sound holes in the ribs, but it sounded absolutely amazing. Nowhere as powerful as a Strad or del Gesu, but what surprised me is how clean and consistent it sounds throughout the entire range, and the examples I've found on KZitem of Zoller violins all have those same qualities. It might make for an interesting experiment.

@@parasharkchari Thank you for the info about Chowdiah and Zoller's instruments! I have not seen those. I am particularly intrigued by Zoller's design. Moving sound holes to the ribs is something I have wanted to try. And yes, I fully plan to do some experimenting with different body designs. The body of the Modular Fiddle is actually the easiest part to change out (after the bridge of course), and so is easy experimentation. I like the idea of designing an adjustable soundpost, but I agree -- how much would it really help? First step is to get a luthier to place one by hand and see what we get. Ha, interesting about the old school master luthiers being more open to experimentation than modern luthiers. It does seem to me that anyone interested in trying something more different ends up just making electric violins. The world of acoustic violins is fairly uniform. That said, it's also incredibly difficult to make a living making instruments, so we aren't exactly encouraging innovation in the space with our economic models. Several months ago I came upon the Hardanger fiddle and became captivated by sympathetic understrings. I have since made a Modular Hardanger Fiddle and it came out great -- I love playing it!

I've been inspired by Louis Armstrong with his sterling silver trumpet to have a violin 3D printed of solid silver. I have been told that this is an optimal carrier of sound and would certainly beat out plastic. Do you think this design would lend itself well to such a project? Has anybody yet thought to try? Can you offer me any advice in terms of this idea?
@openfabpdx

I think that if you try to make a traditional acoustic violin from silver you will need to heavily modify the design. I'm not sure such a thing would work, but I honestly don't know! You might instead try something like a Stroh violin but made from sterling silver. For that instrument the trumpet would be a worthy comparison.

@openfabpdx
5 жыл бұрын
puck spirit, I have not had any trouble with the material degrading. I believe that eventually your top plate will start to deform, but that may take a year to impact the instrument. If it gets warm, like in a hot car, it will sag and fail. PLA is also sensitive to UV, so it will degrade if you leave it in the sun for a long time (like days). Otherwise it’s a production quality plastic and should hold up well. I have a F-F-Fiddle which is very different from these Modular Fiddles, but has been under tension for five years and is as good as new. Some folks have had the layers pull apart over time after building the instrument. I would reason that this is due to poor material quality or lower quality prints.
