Work in Progress: Neutrino Probe – Molding

tn_neutrino_probe_wip_6

If you want to make more than one unit of any given prop replica, it is inevitable to make molds of all the parts you need. This way you’ll be able to make multiple resin casts of each piece. For the Neutrino Probe, this presented a few unique challenges I had to tackle along the way due to the special nature of the body, its prototype parts and the fact that I wanted to put electronics in there. In this blog post I’ll show you exactly what I thought would work, what did’t work and – most importantly – what I ended up doing. [More…]

Tools & Supplies: Vaseline

Very useful when making a mold: Vaseline. It is used as a release agent for silicone mold halves and helps to avoid enclosing the master model in a silicone block. Vaseline is applied with a brush – don’t use it sparingly! There are more specialized release agents for silicone molds, but Vaseline works just fine for me. [More…]

Work In Progress: ODN Scanner – Part II (Molding)

tn_wip_odn_scanner_2In this second installment of my ODN Scanner progress report I will describe how the finished master model (see Part I) is used to fabricate a silicone rubber mold which then can be used to cast resin kit parts.

Because the finished prop was supposed to contain an electric circuit with a super bright red LED and five green sequencing lights, the mold had to be done in a way so that the [More…]
