How 3D Printing Is Rewriting the Future of Coffee Tools: The Engineering Revolution by Vihi Design
How 3D Printing Is Rewriting the Future of Coffee Tools: The Engineering Revolution by Vihi Design The next five years of coffee innovation will not be defined by factories, but by engineering-driven 3D-printing studios. Why 3D Printing, and Why Now? For two decades, coffee tools have evolved slowly. Drippers changed shapes, paper changed textures, but…

G-Flow Active Slow-Feed System: Motor-Controlled Stability for Cleaner Grinding
G-Flow Active Slow-Feed System: Motor-Controlled Stability for Cleaner Grinding Transforming grinder feeding from “random gravity” into “precision-controlled engineering.” What Is G-Flow? G-Flow is an active slow-feed system for coffee grinders — not a passive gravity hopper. Inside it is a motor-driven feed disc that rotates at a controlled speed, grabbing coffee beans and pushing them…
