Elastic buckling vs plastic collapse in concrete printing

This video reviews some failure mechanisms we experienced while printing with different materials. Two failure modes can be easily recognized, but what is the third?

supercool!

What an awesome video! Thanks for posting it. You may consider that more coarse aggregates may help prevent both types of failure, and reduce paste volume. Think of slip-forming highway barriers without course aggregates - they couldn't do it without the shear provided by particle packing.

Thank you for your comments and suggestions on our videos! Pumping large aggregates is not that easy with a progressive cavity pump, but should be looked into. Other pumps exist, but the main problem is that we need constant pressure and flow rate.

plastic and instability interacting together

[@nishanthapa76]

Is it Failure initiated by bearing failure followed by elastic buckling-- later on plastic collapse?
