3D Printed Violin by Bence Balogh November 08 2019
With a BSc degree in Mechatronics Engineering and a Master's degree in Economics, Bence Balogh found a new love for something unusual. As he participated in the Conference of Scientific Students' Associations in the subject of "Examination of 3D Printing Parameters on the products mechanical properties," he found an interesting topic by HovaLabs, an open-source project, the 3D printable acoustic violin.
"I used to learn how to play the piano and the classical guitar for many years, and I also tried playing the violin. Unfortunately, my violin career only lasted for about a month. I was fascinated by the grace of the violin, and I adore when someone is playing it professionally. It became a must to make one in order to test the connection between 3D printing and music," Ben explains.
"The original Hovalin was amazing, so I consulted with several musicians, especially prime violinists. They gave me useful tips about how to improve and develop the model. It became my obsession to create the violin as realistic as I could, based on the Hovalin and the recommendations by the professionals. I am really satisfied with the result so far. However, I am still working on details and collecting feedbacks for further improvements. The 3D printed violin is an instrument, ornament, and something spectacular," says Ben with excitement.
In the beginning, Bence used basic PLA for the prototyping as it is the most common material that's also very easy to use. He had to make a few alternations regarding the bridge, as the strings were too strong and broke the original bridge made of PLA. He decided to use CPE for the neck and bridge because of the strain and holding capabilities. In the end, the body of the violin is constructed from PLA Crystal Clear "Smaragd Green", and the neck with the bridge is made from more rigid CPE HG100 "Iced Green Transparent". Full bodies took 40-50 hours to print on the Creality CR10S. Even with the lower resolution, it took 20-30 hours with few iterations. This project was very time-consuming.
"Many of my friends who play the classical violin helped me, so I learned a lot about the soul, body, and the creation process of a violin. On the other hand, I deeply absorbed 3D printing, maintenance knowledge, 3D design, and remix skills. The most important was to have the patience for this project and the ability to learn from my mistakes. My main goal was to bring 3D printing, music, and people closer together and to challenge myself. Whenever I show the 3D printed violin to people, I see the pure joy and curiosity on their faces, and I think this is the real achievement," Ben tells us. With the help of Stella Nagy, he was able to take breathtaking pictures in The Palace of Music in Miskolc, Hungary.

The "Visitors" Laser gun by Nacho3D September 19 2019
Let us introduce to you Nacho3D an engineer from Spain who brought this nostalgic movie prop project to life.
Late '80s American TV show ‘Visitors’ which was very popular at the time is about humans fighting aliens and this fight was an inspiration for the print. Every good fight needs a good gun. In this case, heroes were shooting with laser guns or laser sniper rifles.
The design of a weapon was ready two years ago, but due to difficulties with supports Nacho3d brought it to life just this year and it is definitely worth it!
Let's dive into some more technical details. The gun was designed with Catia V5, a popular CAD 3D software. Some parts were printed on Ultimaker 2+ with Cura 4.1.0 slicer. Apart from the connector, the gun was printed in PLA Traffic Black with 0,4 nozzle and 0,2 layer height with the recommended printing speed 30mm/s and 215°C nozzle temperature. For the connector was used PLA Crystal Clear and PLA Crystal Clear Iceland Blue. In the case of a connector Nacho3D strongly recommends 212°C and the nozzle, layer height and speed the same as the rest. It took approximately 21hours to print the whole gun.
We were wondering why did Nacho3D pick up this project. “I wanted to try to design a weapon and this laser gun appeared in an 80's series of my childhood, ‘V’ or the ‘Visitors’. It was a USA miniseries about an alien invasion that really was very popular in my country. The laser gun and the laser sniper rifle were the weapons of the aliens, but they were also used by the heroes of the series” he explains. Would you like to put your hands on this project as well? The model is available on Thingiverse or Cults3D.
Saturn V by Carcasaink September 06 2019
While most of the people are printing small gifts and vases, team Carcasaink gets far away from basic 3D printing. Take a look at a really amazing work on printing Saturn V, designed by Paul Fisher.
Hello, how is your day going?:)
My day is doing great as always, printing a lot of stuff, bringing to reality awesome ideas.
What do you have here?
The Saturn V rocket with gantry is our biggest print so far, we choose this challenge because we love the history behind this masterpiece of engineering and this model is very complex and difficult to get done, thousand of parts, small details, everything is just perfect to test our machines and settings.
Who made the model for this make?
You can find the complete model here: https://www.thingiverse.com/thing:911891 all the credits to its creator! (Mr. Paul Fischer, editor’s note)
What materials did you use?
We used Fillamentum PLA in the whole print and a lot of crazy glue to join the pieces together.
Was it hard to finish?
Was pretty hard to finish because not only the bunch of pieces that were printed (over 2000) but also because of the fine details and the time that took the big ones. Some pieces required almost 3 days to get done, some parts of the rocket (for example, the F1 engines) took a lot of hours of gluing and because they are small pieces, sometimes the assembling process was challenging. The rocket itself was easy to print and glue together but the gantry was pretty hard, not only because it has a lot of parts but also the precision is a must.
Why did you choose Fillamentum materials for this project?
Because of its reliability, vivid colors, easy to print and its price.
VooDoo Bree by Arte Creator July 01 2019
Did you know that Arte Creator is not one designer but a fantastic duo: Barbara & Goncalo? Now you do, and let’s talk to them about their latest design - Voodoo Bree!
Followers on our social networks may already know you for your epic designs of Bree and Summer - the skater girl. Now you’ve prepared something brand new, inspired by our Voodoo.
The idea came when you guys posted some photos of the original Bree printed with voodoo filament by some makers. You guys called her Voodoo Bree at the time. We loved the name and answered back playing with the idea that even better was to make a version of her matching the name. Something like Tia Dalma from the Pirates of the Caribbean movies. That idea never got out of our minds, so of course, we had to make her!
We think she looks fantastic in every colour, but sure, the prints from Tore Langelandsvik and Tom Jackson were fabulous! Where can we find the stl?
Indeed they were amazing prints that add value to the model! The STL can be found at MyMiniFactory LINK.
We were writing with you during the designing process and found it interesting to talk about it. How many iterations did you print until you got to the final shape?
Our previous models: Summer and Bree gave us a lot of experience through several experiences and iterations. They paid off with smoother production flow with this new character. As then, we’d already known what works and what doesn't. The printing went well at the first try: with her cap, head, body, featuring many details and she’s support-free. Only the base (or stand) was more labour-intensive the leaves where something new to us. As for the 3D model, there where a few iterations like the angle of the head, the hair, different cloth details, the base size and the amount of branches and leaves in it.
Which head angle didn't work out? As a designer, how do you see the need to change design because of printing?
Some angles don't work out because they can actually change the personality or intention of the character; a head bending over the doll would look intimidating if not awkward. If she were tilted to the right, it would break the flow and the body line. So we opted for this angle as it’s more like a “haaaw, you are a cute doll!! The things I'm going to do to you!!”
Her pose, similar to the original Bree, is intended to help achieve our model without supports, as the printer will always go at a printable angle. It starts going from the base to the hips, where the hands and arms are in an angle that the machine can handle without overhangs, and from there to the neck. The head was made separately as there was no way to make it without support, and it is cut flatten same as the cap so they can be printed flat on the printer bed.
There were some issues with the leaves stand…
The problem with the leaves where the thickness and level of detail. When printing, you would have a lot of small “islands”, this makes the nozzle move like crazy from one point to another leading to some failed prints. That’s the reason why we have to test before releasing the models to the community. This can be tweaked and solved with better cooling and multiple-layered profile printing, but not everyone has, can or want that, and we don't want to impose it. So we tried to simplify the leaves’ shape, merge them a bit to make them easier to print. Overhangs and printing angles are other things that designers must take into account if they want the model to be as easy to print as possible. These are the models made by makers for makers. We first make sure the model is easy for us to print. If it works for us, it will work for everyone else if we don't push for the printers. If it fails, it will also for other people, and that's not an option, so we’re back at the drawing board!
Zbrush for modeling, our PLA for printing. Btw. what printer do you use?
Indeed, those are our tools! We use mainly our Creality CR10S, but we also have a Creality Ender 3, a Peopoly Moai, and recently acquired the Anycubic Photon.
Why did you choose our materials to work with?
We have tried other materials before but a friend advised us to try your brand, and so we did, and we love printing with them since then. They work well in our printers, and the results speak for themselves as everyone can see from the photos we have published.
