I finally gave up on that 3D printed concrete project in Denver

Man, I spent the better part of six weeks trying to calibrate a gantry system for a 3D printed retaining wall. Every single pour either slumped over or cracked right down the middle as it dried. I figured it'd be a two week thing tops but it just kept going wrong. Did anybody else run into issues with concrete setting too fast for automated layering?

Yeah that stuff is a nightmare to dial in, I feel your pain.

Read somewhere that someone spent like three weeks tweaking their setup and still couldn't get it right. @rodriguez.mia I totally get what you mean, every little adjustment seems to throw something else off. Heard a guy on a podcast say you basically have to treat it like a whole system instead of just parts. Wish someone would just make a guide that actually works for once instead of all this trial and error stuff.

Honestly @rodriguez.mia, maybe the real issue is the mix ratio throwing off the whole curing schedule.
