Haha - somebody has had you, and quite seriously. There is a reason why timber splits readily when tension is applied vertically to its growth direction, and why plywood and OSB (oriented strand bonded) timber is preferred instead of solid planks. It is called grain orientatio "Pin It")
Haha - somebody has had you, and quite seriously. There is a reason why timber splits readily when tension is applied vertically to its growth direction, and why plywood and OSB (oriented strand bonded) timber is preferred instead of solid planks. It is called grain orientation. Take a look at this video , which outlines some of the problems with 3D metal printing. Others, such as inclusions (e.g. arising from less-than-perfect oxygen exclusion during welding) have not even been mentioned. And porosity? Listen carefully when Hot Isostatic Pressing is mentioned in the video. And so on, and so on. Toughness, whether in the form of fatigue strength or impact strength, of an as-cast product, and 3D printing is simply casting without a mould, is always substantially poorer than what the same metal will be after porosity is removed via some decent forging / rolling.Originally Posted by BuffaloJohn
