Basic Silicone Mold Making & Casting

- CORRECTION: I say 2-part silicone mold, but this is NOT a 2-part mold. This is a simple block mold.
Silicone molds are a great way to make copies of hard to find parts or props but can seem a bit intimidating. In this Halloween How-to I’m going to show you the basics of silicone mold making and casting with resin.

Man the paint trick blew my mind. Thank you
I've dusted molds with mica powder, but I've not seen using spray paint in the 100's of resin videos I've watched. Very cool tip!
Yeah, it's a favorite. Thanks for watching!
Can't wait to tackle this! Great tutorial! Now I can copy my 3d printed props without the WEEKS of printing! 999
Another great video with some really helpful tips and tricks thanks Derek 👍
Thanks guys!!
This is such a great introduction to silicone mold making!
I especially appreciated the final tip about painting the mold before adding the resin! It was totally new to me. Thanks! I love your work!
Thank you so much! Glad it was helpful.
Great tips! The spray paint trick can be a huge help for getting a durable base coat!
Definitely!
Great video. I'm just starting to work with resin. Lots to learn! Thanks for sharing your knowledge. :)
Good luck!
Great video! I appreciate how clear and informative that was. Also, very neat trick with spraying the mold with spray paint!
Thank you! Yeah, the spray paint trick is super handy.
Can't wait Derek!
Been anticipating this one! I always look forward to Noon on Saturday (here in Florida)
Thanks, Kerri!
Great job Derek!
Thank you!
I have wanted to learn how to do this for YEARS! Thank you so much! I’m off to the raves.
Thanks for checking it out.
I love your series of videos!!! Thank you so much!

Thanks, Taylor!
Awesome video!!!
Thank you, Bridget!
Thanks for sharing this!
My pleasure!
Wow!
The baby powder is a great tip!
Yeah, I'm never going back to mold release spray.
I've been waiting for this video. Once again thanks for the tutorial. 999
Hope you enjoyed it!
thanks for all the ideas and how tos -- I subscribed
Thanks for subscribing!!
Great video!
Thanks!
Spray paint method totally blew my mind!
Right?!
Great vid!! Can you make a video on how to make a 2 piece mold? For more 3D props!!
I'll add it to the list!
@@VanOaksProps awesome!! Love your videos!! Always fun to create something new!!
And make sure you close your eyes before blowing the powder out of the mold 😂 Sorry I missed the live Derek. Great tutorial. I work with resin with smaller projects. I like to see others work in resin so I know how different products work.
Yes, absolutely.
You were missed!
VanOaksProps thanks! I usually have an alarm set so I don’t miss the premiere but I must have turned it off at some point? I can only blame myself since my cat can’t open my phone with facial recognition 🤪
I’m mind blown!
Hahaha. Which part was the mind blowing part?
VanOaksProps the baby power and spray paint!
Much cheaper than spray release.
Brilliant idea to build your walls out of cutting boards.
Would the mold chem and the resin chemicals have any fumes when using and need to use out door or is it safe for in door use?
None that I’m aware of, but I’d check the safety bulletin on the Smooth-on website to be certain.
Awesome. How did you make the original part?
I 3d modeled it and printed it in PLA plastic. Then sanded, and sanded, and sanded until smooth.
@@VanOaksProps Rad. Yeah, it looks perfect. Can't wait to see what you're making with these castings!
Wow, so simple a caveman, or me, could do it. Thanks for the tutorial.
You bet!
NOICE!
Thanks for watching!
Is that a 3D printed object you've sealed up in some fashion?
Correct. 3d printed, sanded smooth, primed, and sealed.
Where did you get that piece that you molded?
I 3d modeled and printed it.
VanOaksProps STL online somewhere? Reminds me of the mounding for Haunted Mansion.
@@pgianotto No STL. It's something I modeled for a client. It's based on the door corbels from the Haunted Mansion.
@@VanOaksProps is there anywhere we can find a model to print ourselves?
@@lukemanor3613 Not that I'm aware of.
Do you sale this prop?
I do. Send me an email if you’re interested.
I prefer the rice measurement method. You dont have to calculate for odd shapes either.
Exactly.

This is NOT how you pour silicone into a mold. You should pour it into the lowest corner of the model, avoiding direct contact with the piece you are molding, allowing the silicone to flow over the piece and find its own level. This is a great way to introduce air pockets into your mold and insure a crappy cast.
The tolerance outside of the part was less than desirable, so the silicone splashed onto the "chin" of the part before I moved to the opposite side and poured around the perimeter, which was the lowest point of the mold. I eventually poured directly into the eye sockets, which isn't ideal, but because I knew I was running out of silicone on my first pass (under estimated - rookie mistake, I know) I wanted to make sure that the eyes were dealt with in my first coat. Mold Star is also extremely forgiving as far as viscosity and the evacuation of bubbles before it sets up.
The only real issue I had with this mold was a bit of cure inhibition between the silicone and an area near the teeth where I didn't get a good coat of clear over the filler primer (which does NOT play well with silicone).
