This part deals with all changes and improvements I have established in the prototypes 4. The main change refers to the material I used for 3D-printing. For this prototypes I mainly used a mixture of PLA and wood powder as 3D-printing material. It looks and smells a little bit like wood and you can treat it like wood, e. g. drag it, plane it, fill it, etc..
In addition I tried to stabilize the guitar neck by integrating aluminium T-profiles into the guitar neck. In the following picture you can see a little part of the aluminium t-profile under the fretboard part (prototpye 4a.
Because the stabilization effect was not strong enough I placed a steel bar between guitar neck and head plate. I also made the connection between guita neck and head plate a littel bit thicker (prototype 4b). But even this did not stabilize the guitar neck adequately.
Therefore I mounted a wooden machine made guitar neck on the body of the guitar. That improved the stability of the guitar neck but it is still not perfect (prototype 4c).
In addition I applied for a german “Gebrauchsmusterschutz” for my 3D-build e-guitar and I was successful. Since the 20th of march 2017 my guitar is trademarked by the “Gebrauchsmuster” number 20 2017 000 765.
Still I have some more ideas to improve the stiffness of the neck of my 3D-build e-guitar. More in the next part about prototype 5.
