Solstie developed fully functional acoustic guitar that is FULLY 3d printed (body AND neck) and which can be printed in parts on your home FDM 3d printer WITHOUT any supports and then glued. Only non-printed parts are strings and tuning machines.
It is playable and sounds reasonably well for a music instrument that will cost you 30 USD to make.
This is a great step forward for DIY music since most 3d printed guitars until now were electric guitars where acoustic properties of a body material don't matter and were printed on commercial machines. Necks were rarely printed.
