I was at Reynolds Advanced Materials store and found this…

I still see the striations through the coating. Are they filled in so that a coat of paint would show a smooth surface? |

I held the skull. The treated section was very smooth. I assume the idea is to paint over it. |

Wonder how it behaves on smaller scales…. would it wash out too many details? |

Here is a very good 6 minute video by the new Mythbusters guys (I think that's who they are) they seem to like it quite a lot, for hobbyists like us. Check it out here: link
They are working with some fairly small items also… |

GildasFacit, In a way, yeah. I don't 3-D print, but for those that do, it looks like a pretty good thing. I know, I don't like all those lines on the pieces, so if you could fill em in & smooth it up without loosing detail, I'd say it's a pretty good deal. |

Yes, it doesn't really show up well in the image since the sealant is clear. Perhaps a stripe of paint on the sealed part would clear up the issue. |

@Gildat Facit: Have you varnished something from Shapeways, WSF and covered up the graininess/striations? If so, what kind of varnish? |

I have this and have used it. I didn't notice any difference using it and giving it a wash in acetone. |

"I didn't notice any difference using it and giving it a wash in acetone." ??? Do you mean you didn't notice any difference between those two techniques, or do you mean that you didn't notice any difference aver you used the Smooth-It and then washed that in acetone? As in, the surface didn't seem smoother, didn't hold paint better, etc? |

I printed 2 pieces. I treated one with the Smooth-It and the other I gave a good acetone wash. They were the same in all honesty. |

Acetone dissolves certain types of plastic. The smoothing is obtained by reducing the detail. |

Acetone as I understand it works on ABS but not on PLS. Acetone dissolved shape edges faster so it is doing much the same job. |

I've seen very good results filling striations on PLA using spray-on, water-based polyurethane. It'd be interesting to compare a print treated with the poly and another object treated with the above product side-by side. |

Hmmm… yeah…. not impressed…. sad, because smooth-on generally produces more 'honest' products. still, a fool and his money….. |
| billthecat | 14 Nov 2017 9:54 p.m. PST |
Now that I think about it, Smooth-On/Reynolds must be scrambling to 'adapt' to the new 3D-printing craze? Although in my experience much of their revenue has nothing to do with the small-scale modeling that 3D-printing competes with… I'm talking pouring gallons of silicone… |
