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

Step 1: Creating Ring of Outer Diameter of 50mm

Steps to create ring of outer diameter Of 50mm using Tinkercad & then exporting to Fusion 360 to get perfect circle in 3D Print.

Step 2: Cutting 50mm Dia. Ring & Measuring Circumference

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

Step 3: 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.

Step 4: Cutting 60mm Dia. Ring & Measuring Circumference

  1. Cutting the ring so that circumference can be measured.
  2. 50mm diameter circles circumference is approximate to 188mm.


Step 5: Proving the Ratio of Pi

Above two examples of 50mm & 60 mm diameter circles ratio of circumference to diameter is 22/7 = 3.14
