Design and Fabrication of Less Cost and Efficient Delta 3D Printer Parts

This project is to fabricate the most essential parts of Delta type 3D printer parts so as to make it more efficient in cost and working. This project has 3 vital parts of a 3D printer and they are Effector, Rod end bearings, Connecting rod (Diagonal rod). The Effector is a component that holds the hot end nozzle and other heat dissipating material within it and we in our project made a multi utility Effector so as to hold many hot ends such as Laser cutting, CNC tool, Food extrusion and 3D printing hot end. This Effector is also categorized into two as uphold and bottom hold since uphold and down hold. Rod end bearings are the motion transmission bearings that would transmit motion in a spherical path. We have made a different mechanism to transmit the motion same as to rod end bearing by coupling two universal joints and making some modification in it and made it cheaper in cost and efficient in working process. The connecting rod is the linking rod between the carriage and the effector. This connecting rod is used to transmit the motion from the carriage to the effector and this works in accordance to the design imbedded on the printer. The conventional 3D printer has carbon fibre pipes as their connecting rod and in this project this connecting rod is changed to steel and this one is made so as to withstand the load acting on it and cost efficient. All these parts are connected and made as a single setup and can be used in any delta type 3D printer. The overall cost of this setup is ½ times the cost of the conventional setup.
