Filling Printer ridges.

[jarndice]

Can anyone recommend a product that will flatten the ridged surface of a printed area in preparation for painting.
I usually use Mr Primer Surfacer 1,000 pre paint but the coarsness of this product makes me doubt that "1,000" will do the job.

Good question! I too, await the sage replies.

Really depends on a lot of factors for me.

Small lines - Mr. Surfacer and primer
Medium lines in a small area - (enter favorite modeling filler putty) and primer
Anything in a big area or deeper than medium lines - Red body glaze and primer

I have tried SmoothOn's XTC 3D, but it dried really fast for me. It may be better suited to stuff with less details in my experience.

Another idea is to use some resin (like 3D printer resin), brush it on and UV it. It will work like the XTC 3D stuff. It's stinky (wear mask) and wear gloves as it will burn your hands. Last night I had some resin parts that CA glue wouldn't stick to so I painted some UV resin on them, exposed them to UV light, and bam...solid connection.

Of course there is always a liberal application of sanding in all stages.

It depends on your filament material. Here is a method for ABS and ASA, but NOT for PLA. PVB can be done with IPA.

It does seem like post processing 3D print lines sucks...it does, but I find that it's faster for me to print a piece and post process rather than scratch build. Now that my resin printer is up and running, smaller pieces need little to no post processing which are the ones that are the biggest PITA to post process.

I though I saw a similar thread a short while ago.

Well, what do you know, I did see a similar thread

Thank you everyone for your very helpful responces,
I shall try what appears to be the easiest way first, That is Bumper Paint,
I shall let you know if it works.

I'll second Jarndice's thanks. Some good methods to try out. Like everything in this hobby, several techniques to have up your sleeve always helps.
Yet another occupation to add to the list of professions I respect and admire:
Welders
Drywallers
Seamstresses
Autobody finishers
Stonemasons
3D parts finishers.
