Does Vibration Work? Let's Find Out!

Bubbles are the bone of resin casting. Vibration is a popular technique for removing bubbles but is it really effective? In this video I test vibration and vibration combined with pressure to see if it helps.
I also demonstrate why vibration is useless against the biggest source of bubbles: resin foaming.

Here is a list of suppliers for the rubber, resins and waxes I use in my videos:

Do you have a project to suggest for the channel?

    Vibrating or knocking is a left over technique from plaster mould making, somehow it has found its way into Silicone mould making.

    Great video! You consistently test theories that bounce around in makers heads and show all of the processes and even throw in variables. Love every single one of your videos!
  • @JennyPoolton
    You do make me chuckle Robert. I love your sense of humour, and your sense of fun during your experiments. I'm not a model maker but I always drop by to see what you are doing.
  • @buzz_4stroke192
    Mastering the process thru experience and sharing your knowledge is gold!
  • @strikerofear
    Well informed and on the topic I've been waiting to see. Good work.
  • @TheArtHack
    This is such an awesome channel! Thanks for sharing your knowledge.

    When pouring it on a vibrator you normally pour at an angle and tilt, and do so quite slowly. That said, that's for pouring yellow gypsum into dental alginate. For a dental model.

    this is cooool a direct response to ours comments. hugs Robert!!!
  • High pours have been the only solution i have found that eliminate bubbles...if not using a pressure pot/vaccum chamber

    Thanks for this, I just bought a gallon set of resin. I wasn't sure how to keep the foaming down but this makes a lot of sense. Thank you for de-mystifying resin casting. Love your stuff!
  • @suitsandsteaks
    I just found your channel and subscribed! I love these videos. Thank you!
  • @truth7416
    Excellent! Thank you so much! I degas. Then vibrate to aid the resin to travel through out the mold faster. I then put it in my pressure pot.
  • @lynnking273
    You are quite a gem. I love your very interesting videos. Thank you!
  • @joevano
    Thanks for the test Robert! Guess that answers that.
  • @arandegoederen
    okay, this answers my previous question - as per your heading. need to get me one of those pressure tanks
  • @Hollow23
    I de-gas my silicone AND use a fibrating table when I make silicone block molds. Works like a charm!
  • What definitive results! Like others, I'd love to see a similar test with the classic talcum powder dusting.

    You proofed withou any daubt what in theory might be knowldge. Very well done aus usual
