A Beginner’s Guide to 3D Printing
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?
- Design: Create or download a 3D model (usually in STL format).
- Slice: The model is sliced into layers using slicing software.
- 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

What Is Infill in 3D Printing
Why It Matters
When it comes to 3D printing, infill plays a critical role in determining the strength, weight, cost, and print time of your object. Whether you’re printing a functional prototype or a decorative model, understanding infill can help you make smarter design and material choices. At BritForge 3D, we optimise every print to meet your needs and infill is a key part of that process.
What Is Infill?
Infill refers to the internal structure of a 3D printed object. Instead of printing a solid block, most parts are printed with an internal pattern that gives them strength while saving material. The outer shell (or perimeter) is printed solid, while the inside is partially hollow filled with a repeating pattern called infill.
Why Infill Matters
- Strength: More infill = stronger part
- Weight: Less infill = lighter part
- Print Time: Higher infill increases time and cost
- Purpose: Match infill to function (display vs. functional)
Common Infill Patterns
- Grid: Balanced strength and speed. Good for most parts.
- Gyroid: Excellent strength in all directions and efficient material use.
- Honeycomb: Lightweight with moderate strength. Popular for visual appeal.
- Lines: Fastest to print, used for basic prototypes.
Recommended Infill Percentages
Use Case | Infill Percentage | Notes |
---|---|---|
Display Model | 10–15% | Light and fast to print |
Functional Part | 25–50% | Stronger, better durability |
Structural Load-Bearing | 50–100% | Max strength, longer print time |
How Infill Affects Cost
Higher infill means more material and longer print times which increases the cost. For example, changing from 15% to 50% infill might double the amount of filament used. At BritForge 3D, we help you choose the best balance of strength and budget for your application.
Infill Tips
- Use low infill for decorative or non-functional models
- Choose gyroid or grid for strength and reliability
- Keep in mind that more infill doesn’t always equal better results
- Use multiple perimeters instead of just increasing infill
How BritForge 3D Optimises Infill
We analyse every print job to recommend an ideal infill percentage and pattern based on use, strength, and cost. Whether you’re printing a bracket, toy, or prototype, we tailor each print to perform as needed saving you time and money.
Conclusion
Infill is more than just a setting it’s the backbone of your 3D printed part. Understanding how it works helps you make better decisions, whether you’re designing a prototype or ordering your first custom part. Let BritForge 3D help you find the perfect infill for your next project.

Understanding Print Orientation and Part Strength
Print orientation is one of the most important yet often overlooked aspects of successful 3D printing. How a part is positioned on the print bed affects not only how it looks but also how strong it is in real-world use. At BritForge 3D, we evaluate each model to ensure it’s oriented for the best balance of strength, accuracy, and surface finish.
What Is Print Orientation?
Print orientation refers to how your 3D model is positioned during the printing process. This determines how layers are built up, how supports are generated, and how forces act on the finished part.
Why Print Orientation Matters
- Part Strength: FDM prints are weakest between layers. Orient your part to resist stress across layers.
- Surface Finish: Vertical surfaces print smoother than horizontal overhangs.
- Print Time & Supports: Orientation affects how much support material is required and how long a print takes.
- Accuracy: Flat surfaces on the print bed come out cleaner and more dimensionally accurate.
Layer Adhesion and Strength
In FDM 3D printing, parts are built layer by layer. The bond between layers isn’t as strong as the material itself, which means parts can be prone to delamination under stress especially if printed in the wrong orientation. For maximum strength, orient parts so the load is parallel to the layers.
Examples of Optimal Orientation
- Brackets: Print with the flat face on the bed and the arms upright to handle load across the layer lines.
- Hinges or Clips: Align so stress points run along, not between, layers.
- Decorative Models: Choose orientation for better detail visibility and smooth surfaces.
Support Material Considerations
Changing orientation can dramatically reduce the need for supports saving time and material. Parts printed with minimal overhangs are easier to post-process and have a better finish.
Tips for Better Print Orientation
- Minimise large overhangs (greater than 45°)
- Orient parts with the flattest side down for bed adhesion
- Consider the functional load design for it!
- Use preview features in slicing software to evaluate orientation
How BritForge 3D Helps
When you upload a file to BritForge 3D, we assess print orientation to ensure it meets your needs. Whether you’re making a working part or a display model, we tweak orientation, supports, and slicing settings to optimise every job.
Conclusion
Understanding how orientation affects 3D printed part strength can be the difference between success and failure. Our team at BritForge 3D takes the guesswork out delivering durable, high-quality prints designed for real-world performance.

How Long Does 3D Printing Take?
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
Item Type | Estimated Time | Notes |
---|---|---|
Keychain or Small Figurine | 30 mins – 2 hours | Low infill, basic shape |
Phone Stand or Medium Bracket | 2 – 6 hours | Functional item with moderate infill |
Large Prototype or Cosplay Part | 8 – 24+ hours | Higher resolution and material use |
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.
How BritForge 3D Delivers Efficient Prints
We use high-speed, industrial-grade printers and fine-tuned slicing profiles to reduce print times without compromising quality. You’ll get a time estimate when you upload your file, and we’ll keep you informed every step of the way.
Conclusion
3D printing times vary, but with the right setup and planning, your prints can be completed faster than you might expect. Whether you need something in 24 hours or just want to understand the process, BritForge 3D is here to deliver precision prints on time, every time.

Advanced 3D Printing Design Tips
Take Your Prints to the Next Level
Once you’ve mastered basic 3D printing, the next step is learning how to design models that print better, stronger, and more efficiently. In this guide from BritForge 3D, we’ll cover advanced design tips to help you get the most out of your 3D prints — whether you’re an engineer, maker, or product designer.
One of the most important advanced design concepts is understanding overhangs. 3D printers can usually handle overhangs up to 45 degrees without supports. By adjusting your model to keep angles under this limit, you can reduce the need for supports, save material, and improve surface finish.
Next, consider fillets and chamfers on edges. Sharp corners are more prone to cracking or warping due to stress concentration. Adding small fillets (rounded corners) not only makes your part stronger but also improves layer adhesion and printability. Chamfers can also help with ease of assembly or aesthetics.
Wall thickness is another critical factor. Thin walls (under 0.8 mm) may not print reliably, while excessively thick walls waste material and increase print time. For most functional parts, aim for walls at least 1.2–2 mm thick. This provides good strength without unnecessary weight or cost.
Adding ribs or gussets can dramatically increase the strength of flat parts without increasing thickness everywhere. Think of how aircraft wings use ribs to maintain lightness and strength. Similarly, adding strategically placed supports inside your design can reinforce large, flat sections.
Embossed or engraved features add detail, but should follow some minimum size rules for FDM printing: text should be at least 2–3 mm high with a line width of 0.4 mm or more. For SLA/resin printing, finer details are possible, but design for your specific printer’s resolution.
Clearances and tolerances are essential for parts that need to fit together. For FDM, plan 0.2–0.5 mm of extra space between mating parts to allow for printer variances. Resin prints may need slightly larger gaps due to resin shrinkage and over-curing during the printing process.
Another advanced strategy is using variable layer heights in your slicer. Thicker layers in less detailed parts and thinner layers in areas with fine details can save time while maintaining excellent surface finish where it matters most.
Consider print orientation during the design phase. Design your part so it can be printed with the largest flat area on the bed, reducing supports and warping risk. Parts designed for printing upright may have fewer surface imperfections and better dimensional accuracy.
Designing with infill patterns in mind can also improve performance. For example, honeycomb or gyroid patterns distribute forces more evenly. By designing your model’s internal features to complement these patterns, you can create parts that are both light and strong.
Finally, remember that every printer and material behaves differently. Prototype your design in inexpensive PLA before moving to more demanding materials like PETG or nylon. At BritForge 3D, we’re happy to print test pieces, suggest improvements, and help you get perfect results with advanced prints.
Conclusion
Advanced 3D printing design isn’t just about creativity — it’s about engineering your models to print reliably, efficiently, and with the desired performance. By applying these tips, you can reduce failures, save time, and make professional-quality parts. Need help with your next design?
