A Beginner’s Guide to Additive Manufacturing
Introduction
3D printing, also known as additive manufacturing, is revolutionising how we create objects — from prototypes and replacement parts to customised designs. This beginner-friendly guide breaks down what 3D printing is, how it works, and why it’s such a game-changer.
What is 3D Printing?
3D printing is the process of creating a three-dimensional object from a digital model by adding material layer by layer. Unlike traditional subtractive methods (like milling or carving), additive manufacturing builds objects from the ground up, minimising waste.
How Does It Work?
- Design: You start with a 3D model, often created in CAD software or downloaded from platforms like Thingiverse or Printables.
- Slicing: The model is sliced into thin layers using software like Cura or PrusaSlicer.
- Printing: A 3D printer follows the slice data to extrude or cure material, forming each layer until the object is complete.
Types of 3D Printing
- FDM (Fused Deposition Modelling) – Most common and budget-friendly; uses plastic filaments like PLA, PETG, and ABS.
- SLA (Stereolithography) – Uses UV light to cure resin; ideal for fine details.
- SLS (Selective Laser Sintering) – Uses lasers to fuse powder; great for strong, functional parts.
Common Applications
- Rapid prototyping
- Custom parts and enclosures
- Art and cosplay props
- Educational tools
- Product design and testing
