3D Modelling and Printing

What are the key factors to consider during the ideation phase for a 3D printing project?

• Material cost

• Model complexity

• Printing speed

• Raw material

What are some alternative materials that can be used for building simple models instead of using a 3D printer?

• Metal sheets, glass, ceramics, and rubber

• Foam board, cardboard, plastic sheet, and acrylic sheet

• Wood, fabric, stone, and resin

• Silicone, leather, vinyl, and concrete

What temperature settings are recommended for printing with PLA materials?

• 100 - 150°C

• 180 - 230°C

• 200 - 250°C

• 120 - 180°C

What are the main differences between various types of PLA filament materials?

• Colour options

  and

  texture

• Cost per kilogram

  and

  appearance

• Brand reputation

  and

  environmental impact

• Filament diameter

  and

  printer compatibility

What are the essential steps for calibrating 3D printer before starting the printing process?

• Cleaning the build plate

  and

  checking filament supply

• Levelling the build plate

  and

  setting the print speed

• Selecting the correct filament

  and

  testing the extruder

• Calibrating sensors

  and

  setting print area dimensions
