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.

The Basics of 3D Printing
What Every Beginner Should Know
Have you ever wanted to turn a digital idea into a real, physical object? That’s exactly what 3D printing allows you to do — and it’s more accessible than ever. Whether you’re a designer, student, hobbyist, or engineer, understanding the basics of 3D printing can open up exciting opportunities for creativity and innovation. In this comprehensive guide from BritForge 3D, you’ll learn how 3D printing works, what materials you can use, and why it’s changing the way we make things.
What is 3D Printing?
3D printing, also called additive manufacturing, is a process where objects are created layer by layer from digital designs. Unlike traditional methods that cut, drill, or cast shapes, 3D printing adds material exactly where it’s needed. This makes it possible to produce complex geometries that would be impossible or very expensive with conventional manufacturing.
How Does 3D Printing Work?
Here’s a simple breakdown of the process:
- Design: Create your 3D model using CAD software, or download it from sites like Printables or Thingiverse.
- Slicing: Use slicing software (e.g., Cura or PrusaSlicer) to convert your model into layers. The software also generates instructions for the printer.
- Printing: The printer follows these instructions, depositing material layer by layer until the part is complete.
This process can take anywhere from minutes to days, depending on the size, complexity, and printer settings.
Common Types of 3D Printing Technologies
For beginners, the two main types of 3D printing are:
- FDM (Fused Deposition Modelling): The most common and affordable option. FDM printers work by melting and extruding plastic filament through a nozzle, building parts one layer at a time. They’re great for prototyping, mechanical parts, and everyday items.
- SLA/DLP (Resin Printing): These use liquid resin cured by UV light for extremely detailed, smooth prints. SLA is ideal for jewellery, miniatures, or objects requiring fine detail, though it involves more post-processing.
Materials for 3D Printing
Choosing the right material is critical for your project’s success. The most popular beginner materials include:
- PLA: Easy to print, eco-friendly, and perfect for visual models or prototypes.
- PETG: Durable, flexible, and resistant to moisture, making it ideal for functional parts.
- ABS: Tough and heat-resistant, but more challenging to print due to warping.
- Resin: Used in SLA printing for high-detail parts with smooth surfaces.
Each material has its pros and cons depending on strength, flexibility, and appearance. Knowing these differences will help you select the best option for your project.
Benefits of 3D Printing vs. Traditional Manufacturing
3D printing offers several advantages over traditional manufacturing techniques:
- Faster prototyping reduce design cycles from weeks to days.
- Lower costs for small batches or one-off items.
- Freedom to design complex shapes and internal structures impossible with subtractive methods.
- Reduced material waste since only the needed material is used.
This flexibility makes 3D printing a powerful tool for startups, inventors, and anyone wanting to innovate on a budget.

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?

Troubleshooting Common 3D Printing Problems
A Practical Guide
Even the best 3D printers can run into issues from time to time. Warping, stringing, layer shifts, or under-extrusion can turn a promising print into frustration. Understanding what causes these problems — and how to fix them — is essential for anyone serious about consistent, high-quality results. In this guide, BritForge 3D explores the most common 3D printing issues and how to resolve them like a pro.
1. Warping and Curling
Warping happens when printed layers cool unevenly and pull away from the build plate. This is common with ABS and large flat prints. To reduce warping, use a heated bed, apply adhesive like glue stick or hairspray, and consider printing with a brim or raft. Enclosing the printer can also stabilise temperatures and prevent cool air drafts that trigger curling.
2. Poor Bed Adhesion
If your first layer isn’t sticking, the rest of your print is bound to fail. Check that your bed is level and clean, and that the nozzle is at the correct distance from the build surface (typically the thickness of a sheet of paper). Use bed adhesives or textured surfaces like PEI sheets for better grip. Slowing down the first layer speed can also help it stick properly.
3. Stringing or Oozing
Thin threads of filament between parts of your print are called stringing. This happens when the nozzle moves between locations without properly retracting the filament. To fix this, enable retraction in your slicer and increase retraction distance or speed. Also, check your print temperature — stringing often increases with overheating.
4. Layer Shifting
Layer shifting occurs when layers suddenly become misaligned, making your model look like it jumped mid-print. This is often caused by loose belts, stepper motor issues, or the print head crashing into a curled-up part of the print. Tighten your belts, ensure pulleys are secure, and reduce print speed slightly to improve accuracy.
5. Under-Extrusion
Under-extrusion means your printer isn’t pushing enough filament, resulting in weak prints with missing sections. Causes include a partially clogged nozzle, low flow rate, or incorrect filament diameter settings. Check your nozzle, increase flow rate slightly, and ensure your slicer matches your filament size (usually 1.75 mm).
6. Over-Extrusion
The opposite of under-extrusion, over-extrusion creates blobs, rough surfaces, or excess filament build-up. Try lowering the extrusion multiplier or flow rate in your slicer. Also ensure your filament diameter is properly calibrated — if your slicer thinks it’s smaller than it is, it’ll push too much material.
7. Visible Layer Lines and Poor Surface Finish
If your prints look rough or have inconsistent surface texture, it could be due to high layer height, vibration, or temperature fluctuations. Try reducing layer height for a finer finish, print at a lower speed, and isolate your printer from vibrations (using foam pads or a stable surface). Better cooling can also help smooth outer walls.
8. Nozzle Clogs
When nothing is coming out of your nozzle, or extrusion slows down dramatically, a clog is likely. First, try a cold pull using nylon or cleaning filament. If that doesn’t work, you may need to heat the nozzle and carefully push filament through manually or disassemble the hotend for a deep clean. Regular maintenance prevents this issue.
9. Filament Not Feeding
If the extruder motor clicks or your filament isn’t moving, check for tangles in the spool or blockage in the hotend. The drive gear may also be worn or clogged with plastic dust. Make sure your filament path is smooth, the spool rotates freely, and your extruder gears are clean and properly tensioned.
10. Print Stopping Mid-Way
Interrupted prints can result from power loss, corrupted SD cards, overheating stepper drivers, or firmware crashes. Always use high-quality SD cards and keep your firmware up to date. If possible, use printers with resume-on-power-loss features or UPS backup to avoid losing long prints. Monitor temperatures if issues persist during long jobs.
Conclusion
3D printing is a balance of hardware, software, and environment. Troubleshooting may seem daunting at first, but the more familiar you become with the symptoms and causes, the faster you’ll be able to act. At BritForge 3D, we apply this expertise to every job, ensuring our clients get perfect prints — every time. If your project requires reliability and quality, trust the experts.

Why 3D Printing Is Ideal for Small-Batch Replacement Parts
When a plastic part breaks, the usual answer is to search online for a replacement. Sometimes that works. But often the part is discontinued, too expensive, unavailable, or only sold as part of a much larger assembly.
This is where 3D printing becomes a very practical solution.3D printing is particularly useful for small-batch replacement parts because it does not require expensive moulds or tooling.
Traditional manufacturing methods are excellent when thousands of identical parts are needed, but they are often not cost-effective when someone only needs one, two, five or ten parts.
With 3D printing, a part can be designed, modelled, scanned or reverse engineered, then produced directly from a digital file. This makes it ideal for brackets, clips, covers, adapters, spacers, guides, jigs and many other functional components.
For businesses, this can reduce downtime. Instead of waiting weeks for a replacement part, a 3D printed version may be produced much faster, especially where the part is simple, non-critical and suitable for polymer printing. In 2026, additive manufacturing trends continue to focus on practical uses such as tooling, end-use parts, design flexibility and faster production workflows.
One of the biggest advantages is design improvement. A replacement part does not always have to be copied exactly. If the original failed because it was too thin, poorly supported or badly shaped, the replacement can often be strengthened with better geometry, thicker walls, improved fillets or a better print orientation.
Material choice is also important. PLA may be suitable for visual models or light-use parts, while PETG, ABS, ASA, TPU, nylon or carbon-filled materials may be better for functional applications depending on heat, flexibility, strength and environmental exposure.
At BritForge3D, we look at the purpose of the part first. Is it decorative? Is it load-bearing? Will it be outside? Will it be near heat? Does it need flexibility? These questions help decide whether the part is suitable for 3D printing and what material should be used.
3D printing is not always the right answer. Some safety-critical, high load, high temperature or regulated parts may need specialist manufacturing, testing or certification. But for many practical replacement parts, it can be a fast, flexible and cost-effective option.
If you have a broken part, old component, discontinued fitting or small production requirement, BritForge3D can help assess whether 3D printing, 3D scanning or reverse engineering is the best route.
