A group of Carmelite monks in Wyoming is building a Gothic church — not restoring one, building one from raw stone — using Prussiani 5-axis CNC machines, wire saws, and a digital sculpture-to-Gcode pipeline that maps remarkably well onto modern manufacturing workflows. The project lands in a strange and productive space between medieval ambition and contemporary fabrication. The pipeline works like this: a head carver sculpts ornate foliage, gargoyles, and architectural elements in a 3D modeling program (Mudbox, from the screenshots). Those digital models pass to CNC programmers who generate toolpaths in CAM software, juggling tool selection, collision avoidance, fixturing, and surface finish. The Gcode then goes to sawyers who operate the machines, set reference points, and monitor cuts. It's a three-role division — artist, programmer, operator — that mirrors any serious CNC shop, just pointed at pinnacles instead of aerospace parts. The machines themselves are Prussiani Engineering units out of Bergamo, Italy — 5-axis with optional 6th-axis lathes for tall elements like pinnacles and statues. They run unattended overnight, turning a 40-hour human work week into less than two days of machine time. Diamond-tipped tools grind the stone with water cooling. The monks also use wire saws — simpler 2-axis CNC profiles — to cut straight elements like columns and window surrounds from large slabs, freeing the 5-axis machines for ornate work. The honest charm here is the overnight disaster story. Early on, a batch of bad Gcode told a machine to repeatedly pound into finished window sills after completing the cut. Several-hundred-pound stones were thrown around the enclosure like toys. The machine survived and is still running a decade later. It's the kind of war story that earns credibility in any shop — you learn your failure modes by living through them. What makes this genuinely interesting rather than merely charming is the argument embedded in the workflow: Gothic architecture died not because people stopped wanting it, but because the labor economics of hand-carving made it financially impossible. CNC changes that equation. Ornate pieces that took a skilled carver months now take days. The monks frame this as unlocking beauty that was being "cut out" for budget reasons, and that framing holds up. The constraint was never aesthetic preference — it was carving hours per stone. The project also functions as a skills bridge. The monks note that young people arrive untrained in hammer-and-chisel work but fluent in computers. Rather than treating that as a loss, they route it into 3D modeling and CAM programming. The medieval craft tradition gets preserved in output (the stone) while the input method updates to match available skills. It's a pragmatic move that avoids the false choice between tradition and technology. The limitations are worth naming: this is a project website, not a technical paper. There are no cost comparisons, no detail on stone types or failure rates, no discussion of how CNC-carved stone weathers differently (or doesn't) from hand-carved stone. The claims about "unprecedented 3D reliefs" and "practically limitless" capability are enthusiastic but unquantified. What's here is a credible, detailed workflow description from people clearly doing the work — and that's enough to be worth your time if fabrication, architecture, or the intersection of craft and computation interests you.
