  • 1. Modified Delta Robot based 3D Printer using Parallel Manipulation Group # 09 Attiya Rehman 2010079 Hira Shaukat 2010131 Talha Hisham 2010362 Ubaid-ur-Rehman 2010366
  • 2. OBJECTIVE “ The development of a more accurate and efficient design for 3D printing. We will be researching on parallel manipulation with the incentive of providing a better and cheaper technique for additive manufacturing.” • Greater Accuracy • Greater Efficiency • Lower Manufacturing Cost • Innovative Approach
  • 3. BASIC PRINCIPLE Fused Deposition Modelling Delta Robot Structure Parallel Manipulators
  • 4. LITERATURE REVIEW 3D Printing: “3D printing is a prototyping process whereby a real object is created from a 3D design.” Layered Printing: Similar to an Inkjet Printer, a 3D object is made through layer by layer printing Prototyping Technologies: Selective laser sintering (SLS) Fused deposition modelling (FDM) Stereolithography (SLA) Laminated object manufacturing (LOM) Electron beam melting (EBM) SLS FDM
  • 5. LITERATURE REVIEW Designing Models: – Computer Numeric Controller – Delta Robot Delta Robot: • parallel robot • three arms connected to universal joints at the base • key design feature – parallelograms in the arms to maintain the orientation of end effecter. Delta CNC
  • 6. LITERATURE REVIEW Control Parameters – Desired position of print head is achieved using position control of the linear actuators. – Flow of material through the print head selected according to requirements
  • 7. HARDWARE The main structure Stepper Motors Print head Bearings Material Used
  • 8. INTERFACING G-Code Coming Firmware Control signals towards the motors
  • 9. Generate a 3D Model Save an STL Format File Slicing the 3D into layers G-Code Generation Towards the Arduino Controllers SOFTWARE • CAD • SLICER
  • 10. EQUIPMENT Frame : • Top and bottom frame: Hand-cut plywood • Side and Back frame: Hand-cut plywood • Fasteners: Stainless steel Electronics : • Stepper motors: 4 (3 positioning, 1 extruder) • Endstops : 3 top endstops & 3 bottom endstops • Electronics: Arduino Microcontrollers. • Power Supply: Depends on printhead and motors • Fans: Cooling fans
  • 11. EQUIPMENT Linear Motion: • Fish lines: Optional • Timing belt: 3 belts (Closed loops or open end) • Timing belt pulleys: 3 plastic pulleys with teeth. Smaller would probably work better. • Smooth rod: precise smooth rod - Aluminium • Linear bearings • Ball bearings and Additional bearings needed for extruder.
