The furniture objects have now been prototyped in different materials, scales, locations and tools. After CNC routing plywood at full-scale and laser cutting acrylic at 1:6 scale, we got to Flojet aluminum sheet at 1:6 scale. We made numerous tests, where we incrementally offset the jet inside and outside the cut line. We finally found that a .0135″ offset outside the cut line accounts for the slight taper of the cut created by the Flo beam, and produces pieces that fit together perfectly. We are indebted to Chris Deptola at AMS in Louisville for his patience and expertise in collaborating with us on these prototypes. We’re happy to know the furniture design works with the properties of three distinct materials and three CNC tools, which brings AtFAB a step closer to a successful future of open design.
