Theory

Settings

  • Translucent PETG
    • Higher Temps - Printed roughly at 270
    • Slow Speeds - 25mm/s
    • Larger Nozzle - 0.6mm less layer lines
    • Vase mode (eine layer line)

FDM Printers

Fused Deposition Modeling 3D printers have the following main components:

  • Mainboard: Interprets G-Code (instructions for printing) and controls hardware: motors, temperature, fans, sensors...
  • Hotend: Melts and and extrudes the filament
    • Nozzle: Where melted filament is extruded
      • Brass nozzles for general use; hardened steel or ruby for abrasives
    • Heater Block: Contains a heater cartridge that heats the hotend
    • Heat Break & Heat Sink: Prevents heat from traveling too far up the filament path (avoids jams).
    • Thermistor: Monitors temperature
  • Extruder: Feeds filament into the hotend
    • Types
      • Direct Drive: Mounted directly on the hotend - good for flexible filaments
      • Bowden: Mounted away from the hotend - lighter toolhead, faster prints, but can struggle with flexible materials
    • Key parts: Drive gear(s), tensioning arm, stepper motor
  • Motion System: Moves the printhead (X and Y axes) and bed (Z axis)
    • Stepper Motors: Precisely control movement
    • Belts & Pulleys: Common for X/Y movement
    • Leadscrews or Z-rods: Usually drive the Z-axis
    • Linear Rails, Rods or Bearings: Guide movement smoothly
  • Build Platform (Heated Bed): The surface on which the print is built
    • Heated Surface: Prevents warping by improving first layer adhesion
    • Surface Material: PEI sheets, glass, textured sheets - different materials for different filaments
    • Leveling Mechanism: Manual knows or automatic bed leveling ( via sensors like BLTouch or strain gauges).
  • Power Supply Unit (PSU): Converts AC to DC to power all components
    • Typical outputs: 12V or 24V
  • Cooling Fans:
    • Types
      • Part Cooling Fan: Cools the filament right after extrusion for better overhangs/bridges
      • Hotend Heat Sink Fan: Prevents heat creep
      • Electronics Cooling Fan (optional): Keeps the board and stepper drivers cool
