PETG gives slightly more pronounced highs. If printed in PLA or ASA, the tone will be a bit warmer. The sound difference between them is, at least to us, really minor. We tried printing one from Prusament PLA, PETG and ASA. So how will different filament materials affect the sound? Plastic recorders are louder and brighter, whereas the wooden ones are typically more mellow. To an untrained ear, the difference between them isn’t huge. Off-the-shelf recorders are usually made either from injection-molded ABS plastic or from wood. You can even try to copy historic designs, which you’d normally have no way to try and play on.Įffect of different materials on the sound Different shapes will change the sound characteristics. Alternatively, you can use a technical drawing to make sure all the holes are in the correct position. Or, to make things even easier, you can just add shapes to the existing recorder model, creating a remix.
If you want to create your own design, we found it the easiest to import an existing recorder model into the modeling software and simply trace over the position of the finger holes. If looking cool wasn’t good enough, it plays really well too! If you or your kid thought that custom colors for a recorder are cool, just think about the possibilities of customizing the shape of it! Michal Fanta, a super talented designer and for a few years now also a member of the Prusa team, has created this amazing Darth Vader recorder and even a Multi-material version of it. The tape will compress a little bit when you put the parts together, so you can create really snug connections.
If the fit is too loose, you can simply cut a piece of painter’s tape and wrap it around the printed part. Check the fit regularly as it’s really easy to sand away too much. If the fit is too tight and you’re unable to fully insert one part into another, use a piece of rough sandpaper to take some material away.
Some connections may turn out that way right after printing and those that do not are easy to fix. When assembling the parts together, the press-fit needs to be absolutely perfect to prevent any air leaks, otherwise, the recorder will sound terrible. The design on PrusaPrinters thankfully includes this adjusted alto-version as well. While this one part needs a slight adjustment, the remaining parts will work without modifications. Though the increased size of the fipple will literally take your breath away as Lysinthea81 describes. Not only that, you can turn a soprano recorder into an alto one by scaling it to 150%. It’s freeing that you can print it in any color you want and the color schemes can be even cooler if you use the Color change feature in PrusaSlicer. Because the individual pieces are still fairly tall and have a small contact area with the bed, it is worth turning on the brim function. Though it has to be said that store-bought plastic recorders are usually not very expensive either. This design only consumes about 60g of filament, which makes it incredibly cheap. PrusaPrinters user Lysithea81 has done exactly that with her recorder model and it’s a really nice one! It can be printed in under 4 hours and it doesn’t require supports. This will make it easy to fit all of the pieces on almost any 3D printer and, as an added bonus, easier to clean. Luckily, we can split the recorder into multiple pieces and it’s something that’s commonly done even to off-the-shelf recorders. Soprano recorders, the smallest from the group, are typically over 30 cm tall. For this reason, we decided to print our recorders using the Baroque layout. No need to learn anything new, just pick it up and go. An F# on a soprano is the same as an F# on a tenor recorder. The benefit of the Baroque layout, among other things, is how all baroque recorders use the same fingerings for all notes regardless of size. If you played on a recorder in an elementary school, though, this might be the layout you’ve been taught. But these days, due to its many limitations, you will only find German fingering on recorders created exclusively for educational purposes. The idea behind the German layout was to make fingering easier. Baroque – hole 4 is smaller than hole 5 (our choice).There are two different fingering layouts: Additionally, one extra hole is on the underside of the recorder and the left-hand thumb is used to cover it. Typically a recorder has 7 holes on top, three for the left hand and four for the right hand. Following the mouthpiece is a hollow cylinder with finger holes, which are used to produce different notes. The recorder has a mouthpiece that is played like a whistle – by blowing in it.
