The Basics of 3D Printing – A Beginner’s Guide

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!

How to Choose the Right Material for Your 3D Print

When it comes to 3D printing, selecting the right material can make the difference between a strong, high-quality print and a failed project. With so many options available from PLA and PETG to ABS and resin, it’s essential to understand the unique properties of each material before starting your print. In this guide, BritForge3D breaks down the most common materials and helps you decide which one is right for your project.

Why Material Choice Matters

The material you choose impacts strength, flexibility, appearance, and even the cost of your final print. For functional prototypes, you might need something durable and heat-resistant. For decorative models, you’ll likely want a smooth finish and a wide range of colours. Making the right choice upfront saves time, money, and frustration.

PLA (Polylactic Acid)

PLA is the most commonly used 3D printing filament and is perfect for beginners. It’s easy to print, affordable, and widely available in multiple colours. However, PLA isn’t very heat-resistant and can deform under stress.

  • Best for: Decorative prints, prototypes, hobby projects
  • Pros: Easy to print, low cost, biodegradable
  • Cons: Lower strength, low heat resistance

PETG (Polyethylene Terephthalate Glycol)

PETG combines the best of both worlds, it’s stronger and more durable than PLA, yet easier to work with than ABS. It’s ideal for prints that need toughness without compromising detail.

  • Best for: Functional parts, mechanical components
  • Pros: Strong, impact-resistant, water-resistant
  • Cons: Slightly trickier to print than PLA, prone to stringing

ABS (Acrylonitrile Butadiene Styrene)

ABS is a professional-grade material known for its strength and temperature resistance. However, it requires higher print temperatures and often a heated enclosure.

  • Best for: High-strength parts, automotive components
  • Pros: Durable, heat-resistant, widely used in industry
  • Cons: Requires controlled environment, emits fumes when printing

Resins

Resin printing offers unmatched detail and surface finish. It’s used for miniatures, jewellery, prototypes, and dental models. However, resin handling requires safety precautions and proper curing.

  • Best for: High-detail models, jewellery, miniatures
  • Pros: Exceptional detail, smooth finish
  • Cons: Messy handling, requires post-curing, higher cost

How to Pick the Right Material for Your Project

Ask yourself these questions:

  • Do you need strength or flexibility?
  • Will the part be used indoors or outdoors?
  • Do you need a smooth, polished finish?
  • Is cost or durability more important?

By answering these, you can narrow your material options quickly.
