Model Parts

The model is also called a Rep-Rap model, the name suggests Rapid Prototyping model which means most of the parts of the model can be printed by the 3D Printer itself. As seen from the picture of the model the printer bed is circular with triangular base structure and also on top.

  • The Delta Model is operated using Nema17 Stepper motors with three at its base and one to extrude the filament. The 3 vertices of the triangular base of the model has the motors over whose shaft the belts are wrapped around which connects the the printhead of the Printer through six tie rods as shown in the Fig1. The motion of the printhead while printing is controlled by the motors and the three vertices of the top triangular frame has switches which turns off the operation of the motors once the printhead reachesa certain position ascertaining the vertical length/ Z axis upto which the printhead can move.
