Speechless !!!! OMG !!!!!

beautiful pieces of art, Arnaud!!
from the drawings to the final painting...we can only look in envy

....ABS plastic sure works well....but in resin cast....pffff....too fragil
I can see....better texture but the problem continue...

Malone, the 3D cast is stronger than resin? which texture is more problematic? (the 3D or resin? and problematic for painting or gluing? please share with us )

Hi, Cheng.
I think I can answer those questions because it's something we've been discussing on and off with Javier this year.
3D plastic is more brittle than resin casts, and it's also harder to glue. The best glue I found is neopren, but it's not a contact glue, so you have to hold the parts together while the glue sets.
The problem Javier is taking about is the grainy surface on the 3D prints, even when they're polished. With resin, you can control how smooth you want the surfaces to be. Resin casts are also cheaper to produce, once you have a mold.

Best,
A.

I totally agree (although I've not sprayed nor glued those few pieces of 3D and resin casts I have) with you...I asked Javier because he seemed to say the opposite...maybe its his English...no offence Javier
...I've been wondering what fillers to use to seal the grainy surfaces before I can achieve a glossy red surface for that Japanese lacquered look...the grainy surface looks more realistic for olden shields, hats, bags, clothes which cant be too glossy...both have their advantages but most of us have neither options

Hi my friends....
Sorry for my english like indians.... .....this way begin the Wars....

Well...really are very differents type of plastic material....with the polyuretane resin I have not problems...we are friends...
But with this 3D plastic....Arnaud said ABS....for me is very strange....I dont understand this material....we are not friends....
To paint I have not special problems....contrary, very well.
But....to improve the texture...I try to use a bit of sand paper....pfff.....impossible....no good result...looks as if it has a low coefficient of friction
If I use a Dremel....with low revolutions.....plastic melts easily .... ....I turn crazy.
Finally I try to apply a coat of clay....more or less good....but only to make a "master" and make moulds....no to  play with.
Toughness and flexibility....beautifull theme....
3D plastic supports better the shock....and the thin parts are more flexible....bends but does not break....in these respects, the ABS is superior...is my opinion...

Well, the silver ones sold out before I could win the argument with my wallet.
