Automatic master mould generation
by RodLaird, published
Rhino3D has a powerful programming language; Grasshopper. This is a Grasshopper programme to generate moulds from any design. There is a video to show how it works.
UPDATE 8.9.15: Grasshopper programme updated to reflect updates to Grasshopper versions since first published. Please remember to install Hoopsnake for Grasshopper too!
This is ONLY going to be useful to you if you have access to Rhino3D version 5 or later.
There is a downloadable Grasshopper programme file and a demo file with a design and a spare. (Where you pour in your mould material). The output of the programme generates a MASTER mould. There are lots of customisation options - many of which you can see in the video. There are also plainly labelled tweaks within the programme for all manner of things; shell widths and slopes, bi-material offsets and interface configuration and much, much more.
A typical use is to create a plaster master mould. Clay slip is then poured into the resulting plaster mould to generate a slip cast version of your design. The design of course has to be castable...
