Всем привет!
Вот у меня возник вопрос : а что матрицы из гипса уже никто не использует?
А они не долговечны, но если несложной геометрии, то для 2-3 формовок пойдёт…

Почему 2-3 формовки? А если пропитать гипс жидким оргстеклом то получиться очень твердая и прочная поверхность!
Жидкое оргстекло- жесть! Вообщет есть формный гипс, так вот если его поверхность обработать эпоксидкой разведённой ксилолом, то формовок на 50 хватит.
