It occurred to me that it maybe as long as hours with some prints before a second or third color is used, and it isn't good to have an extruder on unless it is in use or else a clog might develop. How do multi color machines deal with that?
Also what special format accommodates colors?
I know this isn't a Solidoodle specific question, but I was curious how that can work.
This again comes down to you and planning. You have to arrange the model so that both extruders print at the same time.
A two color model is actually two models that print on top of each other. One is done with one extruder while the other is done with the other extruder. So typically you would arrange the model so each layer gets passes from each extruder.
As for special format, there is none. You just need the two models representing each color, a slicer capable of combining them and creating one file and a dual extruder printer.
Furthermore if you have quality hotend such as an E3D then even after setting for an hour or so a clog should not be an issue. Typically clogs are caused by sitting and not printing come from the fact you are already printing at too high of a temperature. You want the very minimum temp that will work for all phases of the print. Short passes, long passes, dense infill, or sparse infill and so on. Typically you want the min temp that will work with dense infill and long passes and the rest should fall in place.
Everything in 3D printing is a balance. You want the minimum temp possible to achieve the results you want. You want the most speed at the minimum sacrifice of quality. For most people they want quality, speed, and ease of use. Sadly you can never have all three at once. That's just the way it is. 3D printing regardless of marketing hype is not a consumer market yet. It is still a hobby market. Just look at all the "help me" threads for the so called plug and play XYZ machines.
The image below was a dual color print I made long ago. In it you will see the two individual models used to create the single model in the middle.
Don't they also now have machines that melt colors together through a single extruder so basically it mixes primary colors and combines them as it goes?

not really. that was an external addon device you feed the dif filament through then into printer. the device welds the dif colors ends together like daisy chain and takes constant fiddling while printing plus the device is well over $100 after market if its still available it was a few years ago google it as video. here is a more elaborate version that costs like 7x more but calculates when to add colors https://www.youtube.com/watch?v=KlJQBmv9a0I now be advised any time you add another heater to pass filament through your also adding yet more ways for prints to go wrong so definitely NOT advised for non-experts.
So not something like this?:
So not something like this?:
NOPE! thats 3 separate Boden type extruders if you look closer. not 1 and cost is at least 3x

He also can only control the color at a layer level. he cannot mix them. The firmware current machines run on do not allow for mixing the colors to achieve RGB. There some color printers that are well XYZ brand and are garbage but they take a porous filament or powder and inject a colored binder into it. So you really are not controlling color wit the filament and being XYZ there is no support or parts for the machine. Again the best you should be thinking about in the beginning is maybe a dual head where you can print a model that has two colors in it. Like a dice or the ever popular tree frog. Or like the two part model I posted earlier. I do that one for calibration of the dual extruders and make sure the colors do not blend or overlap.

For him he said cost is no limit. He is ready to buy a Stratasys and the tech that will be required to keep it running.

didnt see that, but above he was talking about using a single extruder printer to print in multiple colors in same print. hence my replies
