Many of you might have heard about doodler the 3d printing pen, I think the same technology can be extended to wood as well. At present the 3d Printing pen in wood is not yet available even though 3d printing in wood is available. I see a variety of uses of it in wood works.
Mainly it can be used for decorating doors instead of spending hours carving and making designs people can just draw in designs like they draw with a pen on wooden surfaces. Since it is something simple it will be a nice project to research upon and here we are moving the pen with human hand, complex movement axis and coordinates need not be taken into account which makes easier to build a prototype and try it out.
Also it is scalable large structures like door and furniture and people can just transform an old and dull looking wooden to something unique and royal with some practice.
