Hi,
I am pondering an idea I have here: I want some custom fendering that looks like the full-scale rubber blocks. My 3-D printer prints nice and neat and I hashed up a quick mould to try omething last week:
I have plenty of blu-stuff 2-part silicone, I cast some parts using it (blue parts in image)I did soome googling and saw you can tint the silicone: a) the method using oil based paints just didn't work b) the method using 8 drops of Tamiya acrylic in 8g (total) of silicone worked well-enough I think!
...I know well though that casting silicone is meant for the mould, not the moulding and that's how I always used it before. But does anyone know if these will stand the test of time as
mouldings or would they degrade with UV. They should stick on my hull fine with the silicone adhesive I have.
Pic attached:
- Top: Quick ABS mould knocked up
- Middle: 6 "virgin" silicone fender blocks
- Bottom: 6 blackened silicone fender blocks
...They are to be honest just a little soft but not too bad, each one is 16mm long x 10mm wide x 6mm high. I see there's a "thickener" available but that's expensive at £15. Would talc work (not that I have any!)? I heard corn flour works -which I have but am worried if it would rot over time.
Do I have any good chances here or am I just just wasting my time? I can just print and paint the blocks but I thought it might be worth trying in silicone so at least they are something properly soft.
Thanks for any feedback from those who use similar stuff,
