Hi,
just wondering if titanium is an option as of machinable materials with mpcnc.
I would be interested in making guitar necks, bodies out of it, so we are talking about 50 cm length x 5-6 cm depth x 2-3 cm height for necks.
It would be sheet metal for bodies I guess.
As a side note I am a total newbie/fast learner.
My quick research says that titanium is harder than Aluminium and weaker than steel. It should be millable, but very slowly. I also don’t see you making full guitars out of it with the MPCNC.

Hope someone here elaborates on that.
You can make guitars, it has been done with wood and it is on my to-do list, but I think even in Aluminium it would be pretty hard to do or take a few hours at least.
Get a quote for a guitar sized billet of titanium and I suspect it might explain why no one else has done it yet

That is my second option, but enviromentally questionable maybe, unless like bamboo or non rare wood comes into play.
Aluminum poses a threat as for galvanic corrosion (stainless steel frets?).

Just looked, 909.69 United States Dollar per chilogram …, 3 kg minimum needed, an option for a seasoned machinist/luthier for a full guitar selling at 10 grand.
Maybe neck and hollow body (Ti sheet) alone …
