Poor surface quality on thin section print. *FIXED*

[ScanHD 32]

Hello everybody, im reaching out for some advice on how to improve the quality of this print as it has me stumped.

 

The part is a piece of plastic trim i reverse engineered from the original part and will be used on a show car so must really look great.

 

With that in mind, i printed the part in a specific orientation, and moved the z-seam top always the back (unseen) side of the part. see below

Ultimaker S5

Cure 4.1

retraction is on.

0.2 layer height

 

 

 

support is printed in TPLA with Brakeaway roof/floor

 

 

Help?

it appears that travels might be to blame?

 

on each layer the travels happen before the shell of that layer, but i guess it's affecting the layer below?

There is an option "limit support retractions" which remover retractions when moving in a straight line between 2 supports.

 

 I'll try reprinting without this enabled.

for those that are interested. that setting entirely cured the problem. id recommend this for thin walled parts that have support on both sides of the wall.

 

see before and after pics
