Grey Head… Done!

Posted in Design, General, science fiction, scifi, sculpting, Uncategorized with tags , , , , , , on June 6, 2018 by Jim St Ruth

He’s finally done!

Sculpted in Monster Claw, then moulded in Platsil Gel 10 with an Easyflo 120 resin mother mould that was thickened with Polyfibre II. Then slush cast in Easyflo 120, primed and airbrushed, with two acrylic spheres for the eyes that have white LEDs hot glued into their backs.

The electrics are comprised of 4xAA batteries in a battery pack, two super bright white LEDs, and a resistor, with the LEDs soldered onto small PCBs.

It’s taken me six months to complete him, but I’ve got a lot of other projects on the go, and so overall it’s only a week’s worth of work, most of which was evenly split between sculpting and moulding. The final piece is also my first full head-sized bust sculpt and cast that I’ve completed, and with some help from my partner, my first lighting project too.

I’m so proud of him.

I think I’ll call him Bob.

Grey Head: WIP

A quick update on one of my projects, which is going to be a lamp!

It’s a full-sized bust in Monster Clay, with a clay wall around the base to contain the silicone and resin that I’ll be using to create the mould. I’ll eventually cast it in polyurethane resin, paint it in grey tones, with the eyes formed of acrylic hemispheres that will be filled with Platsil Gel 10. These will then have LEDs mounted behind them, to create glowing eyes!

The eyes have been a bit of an issue for me. I really struggled to work out how to mould and cast them so that I could fill them with silicone to back light.

The options and issues were:

  • Mould over smooth acrylic forms under the sculpt, then cast in resin and drill out the spaces for fresh spheres with a Dremel. This is a really problematic approach, as the eyes tend to be spaces where the resin pools. On a test piece, it took ages to drill out the excess resin, and it was extremely difficult to conserve the eyelids without accidental damage, or ruining the slight interior fold between the eyes lids and the eyeballs. It was also impossible to drill out exactly the right volume for the acrylic hemispheres to then fit inside.
  • Sculpt and mould as above, but then when casting place the acrylic hemispheres in place and pour the resin in around them. This was a nightmare, as although the hemispheres were held in place, it was extremely difficult to slush or paint-cast the resin into the mould without contamination of the hemispheres. Additionally, reaching inside the cast to pour the correct amount of silicone into place was just too tricky.

In the end, I followed so expert advice from the The Moldin’ Years: Rubber and Resin group on Facebook:

  • Sculpt a key onto one of the blank acrylic hemispheres.
  • Mould in silicone and cast in resin, making two copies.
  • Sculpt around these on the main bust.
  • When it comes to moulding, just mould over the whole piece in silicone.
  • Cast silicone copies of the keyed eyes.
  • Insert the fresh silicone keyed eyes into the silicone mould and cast in resin.
  • This should allow me to simply pluck out the silicone eyes from inside the cast, creating empty eye forms that should require very little clean up.

The busts just needs a final polish up… and then it’s onto mouldin’ time!

This will be one of my next physical sculpts in Monster Clay… but the reason shall remain a mystery, perhaps for some time…

Fishy Sculpt: ZBrush Turntable

Posted in 3D, Design, General, Masks, scifi, Uncategorized, zbrush with tags , on August 29, 2017 by Jim St Ruth

This might be a long-term project to sculpt and mould into a silicone mask. I guess that the accessories would be made in resin, perhaps with a sintered mental finish that I can polish up. I’ve got another project to finish first, however, and I want to pull more of my focus back to writing.

So, I might never actually make it… but as a mask, I think it would be awesome!

Much to do still: model the rear and inside, and add texturing… but couldn’t resist posting!

Armored Scout Buggy: Teaser

NewCar1a-JimStRuth2013A quick update of the model. The exterior has been completely retopologised (thanks to the use of Maya’s Quad Draw function and lots of curves to help smooth out the edges and various interior pieces of the body panels). The front wheels now have brake pads and suspension modeled too. The textures are purely placeholders… lots of exciting stuff still to come: interior modelling, full texturing, the weaponry and maybe some exterior armor plating.

Another Alien WIP!
