Flow lines on shiny first layer.

[qholmes 0]

Is there an adjustment to remove or reduce the flow lines on parts? I have this nice shiny finish but you can see the flow lines in the plastic. I am playing with first layer heights and flow rates etc. So far.. very tiny differences if anything. 

 

Thanks

Hi,

 

as far as I know, the only way to remove these lines is sanding (and / or painting).

If you don't want to postprocess the surface of your prints, you might to have to live with them.

Hello,

 

Use a transparent material, or a material with glitters/sparkles in it.
The flow lines on the first layer will still be there, but they are much less visible.

 

Kind regards,

Dennis

Thanks. Dont really want to post process them for now. So i guess i will see if customers hate them. hehe.

 

yes i did use a transparent material for some parts. And i think Dark colors are the worst. 

 

What are the lines anyway.. its not a texture as its smooth.

Is it possible to make the printer fill the inside of the first layer with the outline shape.. it seems like the first two outside lines are better than the 45 deg fill. I will look for some settings.

 

Thanks

In the settings for shell, options "Top/Bottom Pattern" or "Bottom Pattern Initial Layer" (must first be made visible) you could select "Concentric".

Thanks,

 

I did a weird version of that by just changing the number of sidewall layers.. so it did the whole shape using sidewall shapes. 

 

And its funny. depending on the angle it looks amazing.. but if you get the wrong angle because all the lines line up.. its worse. 

 

Thanks for the help.

 

What happens if you set different line widths without changing the tip. It just seems that there would be something that would make that first layer more solid. almost like a first layer ironing.. hehe.

I was able to reduce the flow lines by quite a bit by using a 0.1 first layer. Not perfect but it did help. 

 

Thanks

Printing onto a textured surface (i.e. blue tape) can make the lines less pronounced.
