Concept for a delta robot 3D printer

Design goals

  • Build volume: 8x8x16 inches or 200x200x400 mm
  • Footprint: 12x12 inches
  • Print surface: 8x8 inches heated glass which never moves
  • Mass of moving platform with hotend: less than 100 g
  • Mass of moving platform with two hotends: less than 150g
  • Positioning speed: 800 mm/s in all 3 directions
  • Positioning accuracy: 100 steps/mm in all 3 directions
  • Simplicity: fewer than 200 parts (not including washers, nuts and SMD-mounted electronics)
  • Hardware cost: less than $500 USD

Parts

  • Stepper motors: 4x NEMA 17 (plus extruder motors)
  • Timing belt: High-torque GT2 belt (2 mm pitch)
  • Pulleys: 12 groove aluminum (7.6 mm pitch diameter)
  • Filament drive(s): similar to Ultimaker
  • Ball bearings: 8x 608 (skateboard bearings)
  • Linear bearings: 8x LM8UU
  • Smooth rod: 8x 762x8 mm
  • Diagonal rods: hollow carbon fiber rods from kite shop
  • Diagonal rod ends: cheap ball joints used for model race cars
  • Hotend(s): MakerGear 1.75 mm
  • Top and bottom frame: laser-cut plywood
