The Bitter Lesson
Greg Olson invented Materials by Design in the 1990s. Twenty-five years on, the methodology has receipts and the field has barely adopted it. Here’s why we’re applying the same disciplines to cement instead of waiting for metals to catch up.
Performance-Based Specifications in Architecture: A Complete Guide for Design Professionals
Complete guide to performance-based specifications in architecture. Learn advantages, challenges, and best practices for architects working with outcome-focused material specs.
FusionClaw: an honest look at AI-assisted CAD
Six prompts of Claude driving Autodesk Fusion 360 through the MCP API. What worked, what didn’t, what it implies architecturally, and where this leads when the same approach is pointed at a real M3-CRETE assembly with CADCLAW grading.
We Print Shells!
Digital vs concrete shells, why you should mind the gap more than the shell, and how using the same mix for the wall and the foam can reduce logistics burden.
Will AI-generated CAD outrun V&V?
A market observation on verification, velocity, and the coming bifurcation of AI-assisted mechanical design. Examines the codebase-age problem, three architectural classes in programmatic CAD, and why V&V lags generation.

Why the Loop Matters: Process Variables Are Not Noise
The RILEM TC 304 inter-laboratory study on 3D-printed concrete reveals that printing equipment and process parameters are primary drivers of mechanical property variance. The water/binder ratio alone explains only ~12% of strength variance in the dataset.
Performance-Defined Materials: Where Bits Build Atoms.
The construction industry stands at a crossroads. While many are focused on scaling larger machines or rushing to print basic structures, Sunnyday Technologies has engineered a deeper paradigm shift—one grounded in full-process control and powered by Integrated Computational…
