[Colorfabb XT Clear leaving burnt-looking residue]

Its just the nature of the material and its a real pain. One of the reasons why i don't use XT anymore.

For XT its best to print with thicker layers ( 0.2+ )which also helps with over hangs and curling. Both of these contribute to the brown build up. Using the thicker layers will also make your print more clear.

 

That can't be it... Almost all online examples of things printed with XT are not covered in brown splotches... Anyone have a trick to share here? XT seems like a great material otherwise...

[Colorfabb XT Clear leaving burnt-looking residue]

Hi Ultimakers!

I am printing on an Ultimaker 2 with clear Colorfabb XT.

I have the following settings configured:

-nozzle temp: 240C

-bed temp: 65C

-Print speed: 25mm/s for infill and inner shells, 10mm/s for outer shell

-Infill: 30%

I clean the nozzle before each print. When the print is done (90 min), it looks like this:

Some of the residue periodically falls into the part during printing, leaving non-removable brown spots:

Any idea what I'm doing wrong here?

Thanks,

Josh
