What You Need to Know

If you’re new to 3D printing, you’re not alone it’s one of the most exciting and accessible manufacturing technologies of the 21st century. In this beginner-friendly guide from BritForge 3D, we’ll walk you through the basics of how it works, the materials used, common applications, and how to get started quickly without needing your own printer!

What Is 3D Printing?

3D printing, also known as additive manufacturing, is the process of creating a physical object from a digital model by building it up layer by layer. Unlike traditional subtractive methods (cutting, drilling), 3D printing adds material only where it’s needed making it cost-effective and precise.

How Does It Work?

1. Design: Create or download a 3D model (usually in STL format).
2. Slice: The model is sliced into layers using slicing software.
3. Print: The printer lays down each layer until the object is complete.

Popular 3D Printing Methods

• FDM (Fused Deposition Modelling): Uses thermoplastic filament. Great for strong, functional parts.
• SLA/DLP (Resin Printing): Uses liquid resin cured by light. Best for ultra-fine details and smooth finishes.

What Materials Are Used?

Beginner-friendly 3D prints typically use:

• PLA: Easy to print, biodegradable, great for models and prototypes.
• PETG: Strong and durable, ideal for functional parts.
• Resin: High detail, best for miniatures or jewellery.

Common Uses of 3D Printing

• Prototyping and product development
• Custom tools, brackets, and mechanical parts
• Educational models and STEM teaching
• Hobbyist projects and tabletop miniatures

Why You Don’t Need Your Own 3D Printer

While home printers are popular, you don’t need to buy or maintain one yourself. Services like BritForge 3D let you upload a file, choose materials, and have a professional-quality part delivered to your door no technical knowledge required.

Tips for 3D Printing Beginners

• Start with simple, solid models without thin walls or complex overhangs

Which Is Right for Your Project?

When choosing a 3D printing method for your next project, the two most common technologies you’ll encounter are FDM (Fused Deposition Modeling) and Resin Printing. Both offer unique advantages, and selecting the right one can make all the difference in quality, cost, and turnaround time.

What Is FDM 3D Printing?

FDM printing uses melted thermoplastic filament (like PLA, PETG, or ABS), which is layered onto a build plate to form your object. It’s widely used due to its affordability and ability to create strong, functional parts.

• Best for: Prototypes, mechanical parts, enclosures
• Material choices: PLA, PETG, ABS, TPU
• Pros: Cost-effective, durable, large part sizes
• Cons: Less detailed finish, visible layer lines

What Is Resin 3D Printing?

Resin printing (SLA or MSLA) cures liquid resin with UV light to create highly detailed prints. It’s ideal for small, intricate models like miniatures or dental molds.

• Best for: Miniatures, models, dental parts, jewellery
• Material choices: Standard resin, flexible resin, high-temp resin
• Pros: High detail, smooth surfaces, precision
• Cons: Brittle, messy post-processing, more expensive

FDM vs Resin: A Side-by-Side Comparison

Which One Should You Choose?

If you need a durable prototype or mechanical part, FDM is likely your best bet. But if your design demands intricate detail or surface smoothness, resin printing is the way to go.

How Does It Work?

FDM (Fused Deposition Modeling) is the most widely used 3D printing method in the world and for good reason. It’s affordable, reliable, and perfect for functional parts and prototypes.

How FDM 3D Printing Works

FDM printers melt thermoplastic filament (such as PLA or PETG) and lay it down layer by layer to form a solid object. Each layer bonds with the one below it, creating strong and dimensionally accurate parts.

Why Choose FDM?

• Cost-effective for prototypes and short runs
• Wide range of materials for different applications
• Fast turnaround and simple post-processing

Use Cases

FDM is great for enclosures, brackets, tools, fixtures, and concept models. It’s also the ideal starting point for prototyping your invention before moving to production.

At BritForge 3D, we use precision-tuned FDM printers to deliver strong, affordable results. Upload your file today to get started.

Designing for 3D printing is different from designing for injection moulding or CNC. Avoiding these common pitfalls will save you time and frustration.

1. Ignoring Wall Thickness

Thin walls can warp, break, or fail to print. We recommend a minimum of 1.2 mm for FDM and 0.8 mm for resin printing.

2. Overusing Overhangs

Angles above 45° will require support, which affects surface quality and increases post-processing.

3. Not Considering Orientation

Layer orientation affects strength. Consider the direction of stress on functional parts.

4. Forgetting Tolerances

For parts that need to fit together, leave a clearance of at least 0.2 mm for FDM printing.

5. Overcomplicating Features

Simplify your design for faster printing and fewer issues. Avoid unnecessary fine detail unless using resin.

A Practical Guide

One of the most common questions we get at BritForge 3D is: “How long will my 3D print take?”
The answer depends on several factors, from the size and complexity of the model to the chosen material and print resolution. In this guide, we’ll break it down so you know what to expect whether you’re printing a simple keychain or a fully functional prototype.

What Affects 3D Print Time?

• Model Size: Larger models take longer due to more layers and longer tool paths.
• Print Layer Height: Thinner layers = better quality but slower prints.
• Infill Percentage: More internal material means longer print times.
• Number of Parts: Printing multiple objects increases time, especially if done all at once.
• Printer Type: FDM printers are generally slower than resin (SLA/DLP) printers for small, detailed parts.

Typical Print Times

FDM vs. Resin Print Speeds

FDM Printing: Generally slower but more economical for larger prints.
Resin Printing: Faster for small detailed items, but requires more post-processing (washing and curing).

Other Time Factors

• Pre-Print Setup: File prep, orientation, slicing and machine calibration.
• Post-Processing: Removing supports, sanding, curing (for resin).
• Queue Time: If demand is high, your print may be scheduled in a queue especially for bulk or business orders.

Speed vs. Quality

If you choose faster printing (thicker layers), you may sacrifice surface detail and finish. For display models, thinner layers look better. For functional items, speed and strength may be more important. At BritForge 3D, we help you balance quality and turnaround time to match your needs and budget.

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!

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.
