and thus the process favours selecting more corrosion resistant grades like molybdenum containing duplex stainless steels . The Oregon Dragon Bench has the potential for salt , dirt , and pollution to accumulate in its many tiny ridges , so the 3 % molybdenum in 2209 duplex stainless steel helps resist these additional corrosion risks . 3D printing will be increasingly important to modern economies worldwide . The undulating Oregon Dragon Bench helps explain why : 3D printing allows for fantastic shapes not possible with traditional manufacturing . Importantly , the greater range and complexity of possible designs applies to industrial applications , including oil and gas and maritime , where molybdenum-containing stainless steels are already standard .
WAAM enables the light but sturdy design : the wall thickness is thin where the load is small and thick where it is large , minimising overall weight . Image courtesy of Joris Laarman .
