How to smooth out print lines on Shapeways breacher shields

[Kisada]

I know this is more of a hobby topic but since breacher shields are a 30k thing I figured I may get the best answers here.

 

I bought some breacher shields from Pop Goes the Monkey on shapeways and was wondering how I should go about removing/smoothing out the print lines.

 

Bonus points for end result pics.

 

Thanks

Do you have pictures of the lines in question?

It’s kind of hard to get a picture that really shows it without painting. It’s the print line ridges that come with 3D printing. I figured some people would have purchased these shields before.

 

I hear shapeways is going to have a booth at LVO. If so I hope to get some support from them if I can’t find any info before then

Can you describe the material to me? Specifically what it looks like from the unpolished angle.

You’ll get good results sanding the Shields with a fine emery board. You can get excellent ones in the beauty department of any store that sells makeup. I use a double sided one that’s white and peach colored. They cost about $1.

I clean the shields first with Goo Gone and a toothbrush, followed by a soapy scrubbing.

 

For the large open sections, I have 2,000 grit sandpaper. I don't fret too much about getting every bit smooth, because the ridges are so subtle in places that the spray primer is just thick enough to hide them.
