Nola (http://inchtextiles.blogspot.com.au/) suggested Kinetic Sand for mould / support making. The website describes Kinetic Sand as “98% sand and 2% Magic”, the Magic being a synthetic polymer which the Product Statement reveals to be polydimethylsiloxane, a silicone with unusual flow properties.
Sidetrack sample p1-1. I started with a simple shape – a kitchen bowl.
Traced over with the 3D pen…
Lifted it off the mould…
Structural integrity is very poor, but a reasonable proof of concept.
I also like the colour – it looks like pulled sugar. A little more sturdy and it could make an amusing bowl for lollies.
Sidetrack sample p1-2. What about a more solid shape?
I rolled smooth some kinetic sand, and pressed in a spring clip that was lying nearby.
Tricky at the start, but a result of some sort, with the impression filled with wriggles of plastic.
It came out cleanly – a few extra indents in the sand, suggested I pressed too much at the beginning.
Not an exciting example, but another world of opportunities has opened.
One oddity possibly of interest for specific needs – a short length of colour mixing in the nozzle when changing filaments.
You don’t get much length and it would be a bit of a fiddle changing the filament, but perhaps an ombre effect could be useful sometime. Or I might want a small amount of a particular colour I don’t have.
Other ways of colour mixing?
Sidetrack sample p1-3. An imprint of today’s earring (itself claimed to be made from old silver cutlery).
Bits of colour pressed in – snippets of plastic from earlier experiments. (Sorry the photo is rotated. I thought it would fit the screen better)
The T-pin is to keep a hole for connection to a potential ear-wire.
The earring came out cleanly, the colour fragments well attached, but the hole flawed.
The fix turned out to be easy.
It’s very light, but feels solid. I think this is a greet way to make beads and dangles.
Or I could make shapes relevant to a particular theme in a work. Perhaps work at making it smoother. Or else a series of more or less wriggles, or more or less complete shape, or different colours…
Sidetrack sample p1-4. Can I create a 3d shape, go over it entirely with filament, and extract the sand?
Drawing on the shape was awkward at first, but one could build skills.
Next was getting the sand out.
It took a few minutes, but I now have a somewhat fragile filigree ball. I could add more decoration, say some extra snippets of colour, but didn’t feel I’d learn anything extra from that.
While this was successful in the sense of doing what I set out to, I don’t think it’s the best way of achieving the objective. It also wouldn’t work for more complex shapes.
I think depending on the project you need a mix of working on the flat; freehand 3D; over a mould; into a mould; creating as a whole; joining pieces… I really like this pen, and the Kinetic Sand is a great addition to the toolbox.
