So, as a way of exploring this important topic, he and I will be devoting our attention to failure. AM: Why the Failure? is the new video series from Additive Manufacturing Media in which Simpson and I will look at examples of failed builds and talk about why they failed. We will talk about what we know — or what we can guess — about why the failure occurred.
The first episode appears below. It involves what should have been a straightforward application of laser powder bed fusion to make a simple component in 316L stainless steel. Four identical parts were 3D printed in the same cycle. Three were successful. One of them came out like this:
Here is the build failure we explore in the first episode of AM: Why the Failure? Look for the #AMWTF hashtag on
Why this failure? What happened here? AM users from around the world weighed in to speculate, because we shared the failure in LinkedIn before filming the episode. The two most active threads of response are here and here, and Simpson and I discuss some of these comments within the episode below. Future episodes will proceed this same way — follow the #AMWTF hashtag on LinkedIn to see and comment on each new failure before Simpson and I film our conversation. | This episode of AM: Why the Failure? brought to you by Verisurf
Here is the first episode:
Lincoln Electric Additive Solutions’ robotic metal 3D printing process is a choreographed dance between welding, robots, automation, heat management and machining. The new venture may have a distinct advantage in the field: its parent company’s 125 year-old legacy.
GE Additive’s Ehteshami says, “To make these parts the ordinary way, you typically need 10 to 15 suppliers, you have tolerances, you have nuts, bolts, welds and braces.” With additive, “all of that went away.” The helicopter project is a detail in a story worth knowing.
When your metal part is done 3D printing, you just pull it out of the machine and start using it, right? Not even close.
