Considering material rigidity, damping, and cost-effectiveness, I designed this 1/2-scale 3D-printed violin using PLA+ filament. The design's various aspects are primarily based on the properties of PLA+ filament. Theoretically, carbon fiber and PETG filaments might yield a brighter tone, but I haven't experimented with them.

Because PLA+ density significantly exceeds that of the spruce commonly used in traditional violins, and its rigidity is somewhat lower, my design focuses on enhancing the violin's overall volume, particularly the high-frequency response. The violin employs a low-arch, high-profile design, its form inspired by, and modified from, Francois Denis’ Traité de Lutherie: The Violin and the Art of Measurement. The top and bottom plates are thinner than those of traditional violins, incorporating variable thickness for improved tonal quality, thinner at the edges. To ensure the structural integrity of the main sound chamber, the bass bar's shape is subtly altered. Referencing relevant literature, and considering the characteristics of 3D printing, the f-holes have been redesigned. Each f-hole now consists of three parts and is narrower and more elongated to appropriately attenuate the bass frequencies and enhance the high-frequency response.

The neck incorporates a slight pre-bow; it straightens once all four strings are installed and tuned.

A novel worm-gear-based string tensioning mechanism has been devised. The gear components are 3D-printed using eSUN's PLA+ filament; seven violins have been produced to date without any gear failures. The main body utilizes AiLoKu's PLA+ filament (primarily due to its availability). 4/4 violin strings are recommended, as the design necessitates longer strings.

Hi, do you have a model of the body without the lower mechanical part for me? I would like to print one of your designs like a normal violine to see if the sound is very different. Best wishes!

@viu.logic

I'm very glad to hear your story of designing a 3D printed Violin. I don't have such model currently. But I did created a simple model without the ower mechanical part to verify the sound quality in the very earlier design stage. There is not much different from my spect of view. To print this large model (4/4 violin body as one piece), I had bought a ELEGOO Neptune 4 Plus. I didn't find the earlier model file but I have that violin. I can upload a picture of that violin if you want when I back to home.

Replying to @viu.logic :

Hi, thank you very much for your answer. I did print the 1/2 version for my daughter, so it´s not so big and fits well on my Bambu A1. She is very happy about it. The sound is good. When I find the time, I will try to use your model data to build a version without the gears. I was just hoping that you maybe have already that data, because I have to work so much that it´s hard for me to find the time. Thank you for your good work!

Replying to @DinoMaker :

I will see if I can make a version without the gears:) I will let you know once I finish that.

incredible print. I have some slight bowing where the body pieces meet, but it's probably humidity swings where I live.

A very bright and special violin:)

Assembly complete, but the body and base don't quite fit together well, the bottom turntable feels a bit sticky when rotating

@viu.logic

Thank you for your feedback! The clearance between the gears is very small, so sometimes there may be a slight sticking sensation. Primarily in the earliest versions, the material of the printed gears would undergo slight deformation under significant tensile stress, causing gear skipping, hence the tighter fit between gears in later versions

@Turkinolith

Oh man I would love to see a version of this that can print on the P1S. (print right now is only listed to work with the A1)

The designer has replied

@viu.logic

This model should work for all the BambuLab printers except A1 mini.

@Turkinolith

Replying to @viu.logic :

ah okay, because on the Handy app it won't let me print on my p1S, claims it's an incompatible printer.

@viu.logic

Replying to @Turkinolith :

I have check the setting, and I do check the little boxes which shows this model is compatible with all the printer except A1 mini. The print setting file I had uploaded is for A1, which is the print I have. I think this may cause the issue. If you want to print this voilin, you may try the desktop app and see if it works.

@Thebarber__

Geat design and precise fitment. The only gripe I have is thay the taller portion measures at 255.97mm and really should be slanted with supports. This part will NOT print vertically on on the P1S. I adjusted the z limit to 256 in bambu studio and the print plate hit the bottom with about 6-7 layers left. The 6-7 layers i think will be pure aesthetics so I should be fine when I print the rest of the pieces. Great design and still 5 stars. Ive attached a picture of the top part where my nozzle began to dog into the print because the z limit had reached max.

I checked the camera on the app 4 hours into a 12 hour print and there were only a dozen or so layers printed and the print head was 50mm above the plate still "printing" although there was no filament coming out. There must have been a clog, but i don't know why the AMS didn't detect it?

@viu.logic

I’m very sorry for hearing this!

@Thebarber__

This has nothing to do with the file and all to do with your printer. not sure why you would give 1 star...smh

@user_2936748592

any chance at a 1/4 size version? I can figure it out if you don’t have the time.

The designer has replied

@viu.logic

Not yet. I have to re-design the gear part for 1/4 size to make sure those gears would strong enough to handle the strings.

@viu.logic

I'm not sure the smaller gears are strong enough to handle the strings if we just scale the original models. Also, after scale, you may need choose smaller size carbon fiber pole.

@kktinkering

I am looking for a 1/8 version for my 5yo. Thanks in advance.
