Download Apex from Airwolf3d.com and install it on your computer. Apex is a great 3D printer dual extruder software that is capable of generating complex gCode for two print heads. Open up Apex and load the two STLs:
(1) headstock and body.stl
(2) neck and bridge.stl (hint: you can select two or more files at once to import).
Slice The Parts For Dual Extrusion 3D Printing
After you import both parts they will both rest on the flat 3D printing surface. Don't worry, they just need a little help remembering their true printing location on the printing plane. Before doing anything else, make sure that you have selected the correct 3D printer in settings, in this case you will select a dual Extruder 3D printer such as the Axiom 20 or the Axiom dual head. One of the many great features of Apex software is that it already comes loaded with simplified dual extruder profiles for various 3D printer models. It is also important to select the right material. For example, in the filaments menu you will find a drop down list of materials. As of the date (12/11/16) the drop down list of materials shows 27 materials. Select “ABS Dual Color”.
Next, select the any part and right click. A menu will appear and you will select “Dual Extrusion Merge”.
The two parts will align and “remember” their location as it relates to each other and on the printing plane.
Use 50% infill.
You are ready to save your gCode and 3D print your first dual extruder part.
Taking Dual Extrusion to New Limits
As you can see in this case study, we have broken up the body and neck STL’s into more colorful components. While in tinkercad, we split the neck stl into two parts to add a little more color and variation to the overall look and feel.
We separate the headstock (top yellow flat piece at the end of the neck that holds the tuning pegs and commonly displays the ukulele brand logo) from the neck. We also separated the orange tie bar bridge from the body of the uke so that it might resemble a traditional wood ukulele. To see this 3d printed ukulele in action and hear it is beautiful sound quality, click here for a video (insert link: full size ukulele dual print on axiom 20).
To assemble this Ukulele yourself, you will need only two supplies. The first are machine heads. These are tuning pegs that work using a gearing system to turn the string post. In our orange and yellow uke we use “BQLZR Ukulele 2R2L Chrome Geared Machine Heads with Mounting Screws.” You can find these for about $9.50.
Secondly, you will need some ukulele strings, such as “Aquila Soprano Ukulele Strings Nylgut Regular C Tuning 4U” These come is a set of 4 and offer better sound quality than traditional nylon strings for the low cost of $7.00.
Finally, you will need to tune your ukulele. If you are new to music, don’t worry! You can download many free ukulele tuners and chord chart apps for your smartphone or tablet.
For tuning my Uke, I recommend a free app that goes by the name of “Simple Ukulele Tuner - Free Chromatic Tuner By Ullrich Vormbrock.”
If you are interested in learning how to play, you can find the chords tab charts for many popular songs on this app “Tabs & Chords HD by Ultimate Guitar.”
Congratulations, you are now a “Luthier”! (The term given to one who makes guitars and ukuleles)
Aloha and mahalo!
