The Basics of 3D Printing – A Beginner’s Guide
3D printing is transforming how we prototype, design, and manufacture
Making it more accessible than ever. Whether you’re a hobbyist, entrepreneur, or engineer, understanding the fundamentals of 3D printing is the first step toward creating high-quality prints that solve real-world problems. In this beginner’s guide, BritForge3D walks you through how 3D printing works, what you need to get started, and why it’s revolutionising design in the UK and beyond.
What Is 3D Printing?
3D printing, or additive manufacturing, is the process of building three-dimensional objects layer by layer using digital models. Unlike traditional manufacturing, which often removes material (e.g., cutting or milling), 3D printing adds material only where it’s needed, resulting in less waste and more freedom in design.
How Does It Work?
The process starts with a 3D model usually created in CAD (Computer-Aided Design) software or downloaded as an STL file. This model is then sliced into layers using software like Cura or PrusaSlicer. Each layer is converted into instructions (G-code) that guide the printer to lay down material typically plastic filament one layer at a time.
Popular 3D Printing Technologies
- FDM (Fused Deposition Modelling) – Melts and extrudes plastic filament; most common and beginner-friendly.
- SLA (Stereolithography) – Uses UV light to cure liquid resin; ideal for fine detail and smooth surfaces.
- SLS (Selective Laser Sintering) – Uses a laser to fuse powdered material; used more in industrial settings.
What You Need to Start 3D Printing
To begin your journey, you’ll need:
- A 3D printer (FDM is a great start)
- Filament (like PLA or PETG)
- Slicing software
- A 3D model file (you can design your own or download from sites like Thingiverse)
No workshop required many home printers fit on a desk and plug into a standard socket.
What Can You Print?
From mechanical prototypes and functional tools to cosplay props and custom gifts if you can design it, you can likely print it. The possibilities include:
- Phone holders and mounts
- Replacement parts and brackets
- Custom enclosures for electronics
- Educational models and architectural prototypes
Common Beginner Mistakes (and How to Avoid Them)
Getting a good print often comes down to careful preparation. Common beginner issues include poor bed adhesion, incorrect temperature settings, or using the wrong material. Take time to level your bed, experiment with slicer settings, and start with reliable filaments like PLA. Don’t worry every failed print is a step toward mastery!
