The current weight is 828 grams and that influences the test results. For these reasons, the testing setup was redesigned using topological optimization, reducing the weight to 127 grams to 15%. By using a material with lower specific gravity, titanium Ti-6Al-4V Grade 5, with the current grip design, the weight would be reduced to 478 grams or 57.7%. Using material with lower density, topological optimization and AM DED technology, the new grip (see Figure 8) has weigh 73.4 grams and which is 8.8% of the original weight.
