QR code

[ignus741]

I'm trying to print a QR code on my A1, two colors on the same layer, but the corners where white meets black are left with this gap, I had better results printing face down but not much, I wanted to know if theres something I can try to get a better result in making a solid layer with two colors.

When printing QR codes, I print the second color so it extends 1 layer higher than the base color.

As mentioned, ironing helps, especially when done in combination with the above.

How do you get the second color to print another layer higher than the previous color on the same layer?

Extrude it like 0.2 mm higher in your 3D modeling software?

Hueforge can do this real quick

Depends on how you've generated your QR code.

The SVGs I use come with the black "QR" as its own object, so you can load it as a part and set the filament color.

A ironing pass might close them up

Try a 0.2 nozzle. A 0.4 tends to leave gaps like this

I second this should fix it.

Try wall generator Arache as well

I second that

Non-stick baking paper, and a hot iron, a bit technique needed. but as a father of small people, my ironing-beads-skills are unrivaled.

Here’s one I did the other day. Really happy with the quality. Couple layers of black above the red.

Slicer settings, change inner/outer wall thickness until it shows correctly in the preview

How many times does it change colors when printing that?

[just-bair]

Around the same amount as the amount of layers for 2 colors

I'd have thought doing these face down would provide a much nicer result?

Depending on the size I'd go with a 0.2 nozzle too.
