Tip to avoid color bleed on multi-nozzle machines

If you’re printing a 3+ color helmet and concerned about color bleed, keep the main shell color on its own nozzle and put all logo/accent colors on the other nozzle if possible.

Yes — it can slow the print down a bit, but it dramatically reduces the risk of color bleed into the main helmet surface because its never changing colors on the nozzle that is printing the main shell.

You’ll still want to tune flushing volumes for the logo colors so they don’t contaminate each other, but minor bleed inside a logo is usually far less noticeable. A bleed stripe running through the main shell at logo height, though… that’s a helmet killer .
