Hi all,
I have used modified trunk button of on-line output until recently but it was simple and simple.
I got DM head and I have trial-and-error with 2-color printing with dual head because I wanted to clearly distinguish the boundaries, but in reality it is quite difficult.
Please look at Button.jpg.I eventually compromised.
Because trunk button are based on black filament and the last few layers are printed in white.
Please look at 4.jpg on upper right.Also, I made my own console panel to install clock, USB and Defi meter controller.
Please look at 1.jpg, 2.jpg, 3.jpg and 4.jpgPhoto 4.jpg is include ABS shift knob.
I want to know the sharp two-color know-how of small parts.

@taco Your results look good for the DM head due to the larger 0.4 mm nozzle that is used on that head.

How about a slider or knob for passengers. Grandma—-|-Ex GF

I have the same smearing issue on some dual colour prints and thought the issue was the size of the inlays with the second colour, seems not to be the case

http://www.247guardian.co.uk/The nozzle alignment calibration is not so important on a single material setup but is critical on dual material heads. If this and the nozzle opening are correct then you shouldnt get smears unless the material is warping into the path of the nozzles.

There is no reason why you couldnt print that on a DM Robox. No need for those wipe towers though.
Smaller nozzles will help with XY plane resolution but those details are achieved in Z which you can already easily do.

I am operating CELROBOX for about 15 months, but I tried and tried in white monochrome and made using 0.3 mm nozzle with Z axis resolution using white monochrome on the right side of the photo, similarly with 2 color printing It is a picture in the middle that I tested (Speed is done with 0.5 for 2 colors).
Those with two colors are 0.4 mm nozzles, but it makes me feel blurred because of the color mixing.
I made a compromise by dividing white and layers on black with a struggle against the hardship, printing on a flat object with the object flat.
For me, I’d like to print two colors of smaller letters and pictures on the same side, but I really care about mixed colors.
I am glad if there are any good techniques and ideas.</span><span id=”t-served-community-button” class=”trans-verified-button goog-toolbar-button”></span>Attachments:
it may be nozzle height calibration, perhaps the black nozzle is touching the extruded part of the white nozzle or the other way around.
During height calibration the 2 nozzles are pressed against the bed repeatedly to measure the difference between them.It could also be leaking from one or both nozzles. Try nozzle opening calibration again with those materials loaded.

@taco Do your letters go into the body of the part or are they just on the surface? If they are just on the surface, the problem is because there isn’t enough material being printed to keep the colors separate. You need to have enough material in each letter to establish the color or it will probably smear as you are seeing. This is very important with small features and dual color and is common with most dual color printers. When you print small letters vertically like you are showing you should have a central body of the same color to establish the color so that you aren’t telling to printer to leave tiny drops of material, which will lead to smearing just like you are seeing.
