Sprayable filler? Hi, Im onto model finishing again and a friend of mine mentioned sprayable filler that should be thick enough to fill in layergaps and act as primer. I searched a bit around but couldnt pinpoint a brand or product. Most of the stuff is primer or paste car body filler but no sprayable fillers. Does anyone have an idea or a product that could be used like that?

There is also another trend of painting thick epoxy onto the surface with a paint brush, supposedly it's fairly easy and self leveling. I have not tried this which is odd since I sell epoxy for a living, I think I just have an aversion to using it since it's a job to me. Here is a link to one company if you want to explore this method [www.smooth-on.com]]]> tmorris9 General Mon, 05 Oct 2015 17:50:42 -0400 https://reprap.org/forum/read.php?1,565911,566614#msg-566614 Re: Sprayable filler? https://reprap.org/forum/read.php?1,565911,566614#msg-566614

That 2nd one is pretty indeed. I found the dupli stuff on german amazon as well. Ill give it a try.

The paste filler method is definitely doable it would just be awesome to have a more universally applicable method. I also saw on a recent maker faire a guy who used a tumble sander with wallnut shells in it. Not useful for fine detail but his superhero figurines came our looking nicely. That plus filler primer could work out well I imagine.

I agree on both counts.

tmorris9 - i think they both look good. Maybe doing the tumbler before the filler primer might be worth a try since you increase the preparation of the foundation surface.]]> Mutley3D General Sun, 04 Oct 2015 20:14:46 -0400 https://reprap.org/forum/read.php?1,565911,566610#msg-566610 Re: Sprayable filler? https://reprap.org/forum/read.php?1,565911,566610#msg-566610 www.harborfreight.com]]]> tmorris9 General Sun, 04 Oct 2015 20:04:20 -0400 https://reprap.org/forum/read.php?1,565911,566603#msg-566603 Re: Sprayable filler? https://reprap.org/forum/read.php?1,565911,566603#msg-566603

Here is a photo of 2 trek communicators, one was a single coat of primer sealer, the other was coated with spot putty, sanded smooth then sprayed with primer sealer. (and of course painted).

If you are in the U.S. there is a product called "Dupli-Color Filler Primer" that I use a lot. It will fill in about 70% of the print lines. If you want to go further than that I suggest you coat the part with spot putty and sand it first then use the filler primer. Both of these are available from automotive parts stores.

Or apply a couple of coats?]]> Mutley3D General Sat, 03 Oct 2015 18:59:44 -0400 https://reprap.org/forum/read.php?1,565911,566253#msg-566253 Re: Sprayable filler? https://reprap.org/forum/read.php?1,565911,566253#msg-566253 tmorris9 General Sat, 03 Oct 2015 18:44:14 -0400 https://reprap.org/forum/read.php?1,565911,565914#msg-565914 Re: Sprayable filler? https://reprap.org/forum/read.php?1,565911,565914#msg-565914 Mutley3D General Fri, 02 Oct 2015 20:21:12 -0400 https://reprap.org/forum/read.php?1,565911,565911#msg-565911 Sprayable filler? https://reprap.org/forum/read.php?1,565911,565911#msg-565911
