Concrete-Printer Bonding Window Curve Explorer (2D)

The 3D concrete-printer model runs one print at a time and tells you whether the wall came out sound. This 2D companion answers the more useful shop-floor question: for a given print speed, layer height and mix cure rate, what does the entire adhesion-strength-vs-time-gap curve look like, and how wide is the safe bonding window right now? Drag print speed, layer height or cure rate and watch the stability and cold-joint thresholds slide along the gap axis, reshaping the curve in real time. A marker tracks your chosen layer pause on that curve while a live cross-section animation prints a matching wall, coloring each joint green, amber or red exactly as the curve predicts — so you can see the statistical picture and a single concrete print agree with each other.
