Interlocking Perimeters

A novel approach to layer bonding using spacing variation and compression bonding, fundamentally different from "brick layers." Constant layer height, no dimensional accuracy loss, 5-15% estimated strength increase with no time or material penalty.

How It Works

Interlocking perimeters alternate perimeter spacing between layers using X/Y axis manipulation. Over-extrusion compresses material into horizontal gaps, creating diagonal bonding surfaces as material fills in. All beads are printed at constant layer height. No Z-axis manipulation required.

Now powered by Athena's skeletal wall generation with three flow-scaled bead tiers and geometric overlap bonding. Same concept (alternating spacing for compression bonding, constant layer height) but significantly better results than the original implementation.

Cross-Sectional View

The interlocking structure is clearly visible in cross-section. The cyan regions show where material from adjacent layers compresses together, forming mechanical bonds that significantly improve Z-strength. Estimated 5-15% strength increase with no time or material penalty.
