Thing A Week 3: Casting An Adult Toy In Silicone

As part of my new years resolution to make a new thing every week this year, I have decided to make the third weeks project, casting an adult toy in silicone.

Last week I sculpted an adult toy in clay, this week I am going to cast it in silicone.  I am using a two part mold, made from the same thing I intend to cast the toy in, Dragon Skin 30 platinum cure silicone.

The first thing I had to do is put some spru’s on the model so that it would sit up above so I could get the first half of the mold under the clay model.  This will also give me a place to pour in silicone later to make the final toy.

Then I built a little box around the toy.  I found it helpful to use one single piece of cardboard, so you only have a single seam to close up around the edges.  Be sure you fully seal all the way around the bottom, I used blue painters tape, and some extra clay to keep the corners strong.  I used packing tape to seal up the one corner seam.

Give all sides of the clay model a good spray of mold release, as well as the box, and the floor.  Hold it about 12 inches away from give it a light coat, wait 5 minutes and then do it again.  MAKE SURE YOU GET EVERY SURFACE.  But don’t put too much on or you will get strange surface artifacts on the final object.

Mix up a big batch of silicon, you can use an online calculator to figure out how much you will need.  I use a vacum chamber to get the bubbles out, depending on what you are using for your mold, you may or may not need to do this step.

The finished product.  This particular silicone has a pretty decent pot life, so you don’t have to rush, but you shouldn’t wait too long or it will start to harden in the cup.

Next pick a spot, and pour slowly.  Be sure to pour a very small stream so that it will not trap bubbles in the silicone.  I poured into that little hole on the left, and took my time allowing it to slowly fill up all the gaps, while pushing out any air.

Now wait for it to set up, I waited overnight.  Things like set time, pot life, and other important facts about your silicone will be on the box when you buy it.

after the silicone has set I cut in some key holes so that when I cast the other side it will be hard to mis-align the mold.  I used an X-acto knife to cut them out.

Mix up another big batch of silicone, make sure you spray on some more mold release, and do the same thing again.

After it sets up, remove the cardboard and see how your mold came out.

After I used an X-acto knife to clean up the holes, and the edges.

Clean out your mold, make sure you get all the clay, and all the dust, and everything else.  Spray the inside with mold release, and then close up your mold, and I use rubber bands to make sure it stays put together.

I used some pigment to make the next batch of dragon skin 30 blue.  Removed the air bubbles, and slowly slowly filled the mold making sure to allow the air bubbles to escape.  I ended up having to cut two small air holes (the square blue holes below) to let the last little bit of air out.

Give the sides of the mold a couple taps, and let it set up overnight.  When you wake up, take the rubber bands off and see your new baby!

I used an razor blade to cut the spru’s off, and clean up around the pour holes.

As you can see this left some small defects.  They are pretty smooth, but I am going to try a third casting where I use a different technique to try and make it so that the entire mold can be filled from one end.  Resulting in far fewing pour holes, and better air bubble removal.

And just like that, you have your own sex toy!  The total cost for this project was about $50.  Which is what you would pay for a high end sex toy.  The fun bit is though that you can re-use the clay to sculpt anything you want, and you can make as many of these toys as you want (as you now have the mold).  So future toys will be much cheaper.

 

Thing A Week 2: Sculpting An Adult Toy

As part of my new years resolution to make a new thing every week this year, I have decided to make the second weeks project, sculpting an adult toy.

Hold on to your hats prudes, and wholesome folks, futurecrash is going blue.  By which I mean, I have decided to make my own adult toy.  The first step in this process is sculpting.

If you are going to be casting the toy later in silicon (which I am, stay tuned for next week’s thing a week) you will need to be choosy about what sort of clay you use.  Silicons that use platinum based catalysts don’t do well with sulfur.  So you need to make sure you use sulfur free clay.

I used Scupltex hard, as it is sulfur free, and never dried out, and the hard variety is very firm and easy to sculpt complex geometry.

 

Now might be a good time to say up front, I HAVE NO IDEA WHAT I AM DOING.  None, I have never made a sex toy before, I don’t know what sizes, shapes, whatever will feel good, will work, will fail, anything.  I am flying blind here.  So I decided to make something anyone could use (that means it goes in a place everyone has), I will let your imagination fill in the rest of those details.

I started by making some balls, and rolling them together then attaching them.

I used lots of round things of various sizes to help smooth and shape the form.  I am going for a sorta anal beads with a handle feel here, but the picture above shows it in a rough proces.

The rest of the shots below are process shots, you have to do a lot of smoothing, and small adjustments to the form as you look at it from all angles.  It is surprisingly easy to ruin one side of the toy while you are fixing another, so I kept turning and shaping and turning, until I got something I think is smooth enough, and nice enough to be done.

So yea, that is where we are at this point, I think it will “work” in the sense that it wont fall apart when I cast it, and the finished product will be tough enough.  I have no idea if it will “work” in the sense that people would like to use it.  But I think it will come out nice.

Stay tuned until next week when I figure out how to make a mold for this, and cast a couple versions of it.
