CNC Spray painting

[ynneb]

Has any one ever tried to make a CNC spray painter.

The sort of set up where instead of a router there is a nozzle that sprays different colors of paint?

I can imagine it could be usefull for sign writers. Especially those sign writers who hate vinyl cut lettering. ( Me too )

I just had an image in my mind of grafitti artists carrying a table to a wall to do a midnight masterpiece.

I've been thinking of a paint project that goes something like this:

1. Spray paint a large area of the board
2. Let the paint dry.
3. Coat the paint with a protective coating that can be removed with a light solvent without removing the paint.
4. Cut out an area through the paint/coating to the bare wood.

Repeat steps 1-4 as necessary.

When done, remove all the layers of protected coating down to the finish layer of paint.

It would take some planning to get it looking good, but it seems like a good project for a cnc router.

I don't know what kind of coating would work. Maybe something like a vaseline on a water base paint?

You know it is no wonder that I cannot focus on a single project, there are just too many good ideas floating around on the CNCzone. I always thought I had ADD

http://www.pixation.com/ has 2 really nice looking CNC printers, the BladeJet and the WireJet. However, they're commercially priced, both at over $30,000.

Now that you know it's definately possible, you can get started making one aimed at hobbyists. I'll bet you could sell plans/kits for these and make a bit of money at it.

The BladeJet is really a cool machine - and I've misplaced my link to the HECKTOR. If you've seen it you'll know your project is VERY hobby-able. HECKTOR is an x-y cable system a couple of (german?) students put together. Very much Grafitti potential. I haven't checked in on it for a bit - so it may have been refined/or dead.
Might try thru the Majosoft site.

Amazing!

These guys are those graf artists brinign their table to a wall.. Only the wall is the table, and the rails are wires... and...

and...

brilliant and wonderfuly executed

again.

Yes the Hecktor is very inventive and looks cheap to make as well.

I thought I would bring a few of the pics to the forum just in case some didnt push your link.

Putting other tools on it could also be usefull. Such a device actually shows a high-level of potential commercialization.. With just a bit of refinement, and a different overall design, the thing could be used as a real marking tool .cost only $30 to manufacture, and allow huge work areas for simple marking.. like hangers, demolition sites, etc....


Innovation in the name of art projects is awesome.


Any other ideas on what it could do? A similar mechanism?


2 Color Would be easy to acomplish..

Maybe putting 2 more pullys on the floor and making the cables loops would improve overall reliability.. and moving the paint off-printer head and using a lighter more controlable head would also improve the product potential..

As a grafiti bot, its amazing.

looks amazing! must be done to make a multi-color system... as soon as i have finished my own cnc, this might be the next project....

Hey Vacpress, I seem to remember you starting a thread re sidewalk graffiti machine including drawings and pics. Didn't you post pics of a nearly complete machine or was that just a to demonstrate a concept?

[dang]

I just found this thread after watching an "Ultimate Factories" show on The National Geographic Channel. Incredible show!

Regarding the sidewalk spray painters, I found this.

It's pretty cool.

What about a CNC Router based spray system. Ya know, for small garage type shops?

There could be a water tank underneath it attached to a pump to circulate the H20 and filter out the oversprayed and unused paint.

There could be electrical charging involved to attract a metal based paint to the part.

The body of the router could be built out of plastics to avoid paint buildup from uniform electrical charging and be easily cleaned w/ Simple Green.

All the linear movement accessories would have to be protected from paint exposure or made from plastics, or anchored to avoid electrical charge, or all three.

It's a good idea, maybe a bit of overkill though, as saw horses and human arms can usually be substituted.

Is this topic still alive?

I have recently built a rotating paint brush attachment for my CNC router table....




.....example of the end product!


Here is a link to a couple of pictures and one video of my sign painter project..

That was super creative. Nicely done.
