**Problem Statement:**

Evaluate the limit, or type "DNE" if the limit Does Not Exist:

\[
\lim_{(x,y) \to (1,1)} \frac{9x^{12} - 9y^{12}}{3x^6 + 3y^6} = \boxed{}
\]

**Explanation:**

This problem asks you to evaluate the limit of a function as the point \((x, y)\) approaches \((1, 1)\). The expression contains a fraction with a polynomial in the numerator and denominator. You must simplify or apply limit theorems to determine if the limit exists or if it does not. If the limit does not exist, indicate this with "DNE."
