How to prove Pi that is ratio of a circle's circumference to diameter using 3D printing? This question provoke to write this instructable. It is proved by taking two examples of 50mm & 60 mm diameter rings that, this ration is 22/7 = 3.14.

Supplies

  1. 3D Printer
  2. 3D Filament
  3. Scale

Creating Ring of Outer Diameter of 50mm

  1. Cutting the ring so that circumference can be measured.
  2. 50mm diameter circles circumference is approximate to 157mm.

Creating Ring of Outer Diameter 60mm

Steps to Create ring of outer diameter Of 60mm using Tinkercad & then exporting to Fusion 360 to get perfect circle in 3D Print.

Cutting 60mm Dia. Ring & Measuring Circumference
