Building up a 3D shape from a laser cut net shape to use as a mould on the Roto-Moulder.
Polyprop in the laser cutter being set up..
Working out which colours will cut or engrave.. the blue one or the red one...
The cut net...
Turns out the net i made didn't fit together properly.. me and maths don't mix.. so for times sake i used a spare net that was in the workshop, just to practise, i'll get back to making my own one later once i've got the hang of the process.
Added a little bit of food colouring for something a bit different turns out its does something strange to the chemical structure of the plastic and is a complete failure... i put the food colouring in the net before pouring the J-Cast in to see what kind of effect would come out if it, maybe it would have worked better if i had mixed them together..
(J-Cast ratio 1:1)
Food colouring was maybe not the best colourant to put into it. As you can see the walls have also become thin an stuck to the sides of the mould.. The ratio was bang on 50/50.. The food colouring may be to blame for some weakening?
