I know i'm not the first thinking about this, but i can tell you how i did it if you want.
This is a special support to be placed in a CNC/3DP wich uses the Extruder Motor connection and a 9g servo to control an airbrush.
You can join the group CNC Airbrushing if you want to go deeper with this.
So you will think your airbrush doesn't fit. I designed this for a double action side feed airbrush worth about 30€.
I also used 2 608 bearings, a M8 large bolt, 2 M8 nuts, a 5mm to 8mm coupling, 4 M3x20 for bearing top and airbrush jacket, another larger M3 to attach jacket to body, a TowerPro 9g servo and a Nema17 stepper.
Te stepper is used to control amount of paint, and the servo just control the air flow.
This is my V2 for this project. I previously used 2 servos but Mcode is not sync with the rest of the XYZE code, so i had some problems with definition in some points.
If you plan to experiment with this, you must know that is way more easy to make drawings lets say like a plotter. I mean making lines without changin amount of paint is easy compared with controlling amount of paint shot for each mm.
My bests trys of printing B/N photos by now are made using CNC sofware to make a 3D raster over a Z-height from grayscale model. I use top of "stock material" as origin, and then all "-ZXXX" text in the gcode is replaced by "EXXX".
At the beggining of the program, just after the airbrush is moved over the start point you must "open air" with a M280 Sxx command and close it in the last point of the raster.
Im working by now in 1/2 A4 or A4 but i think this would be better for bigger sizes. If i get complete control over this technique i will paint my bedroom curtains in 6 panels of 100x50 aprox.
The worse part of all this compared to 3dp is the 92db my air compressor makes :S.
If you want to see it in action airbrushing an image please take a look at this video:video You can now also take a look to 5my first attemps airbrushing CMYK
Will you give it a try?¿?
