The BritForge3D Technical Knowledge Hub

Welcome to the BritForge3D Technical Knowledge Hub — a structured, in-depth learning library designed to help you understand 3D printing properly.

Whether you are designing functional components, producing prototypes, or commissioning professional 3D printing in the UK, these guides explain not just what to do, but why it works.

This is not a collection of surface-level tips. It is a complete educational pathway covering strength, tolerances, materials, motion control, efficiency, repeatability, and file preparation.

Each guide builds on the previous one. If you are new, start at the beginning. If you are refining professional workflows, jump to the advanced sections.

Start Here – Core Foundations of 3D Printing

Guide 1 – The Basics of 3D Printing

Understand how 3D printing works from digital model to finished part. Learn how slicing software converts models into layers and why layer-by-layer construction affects strength and reliability.

Recommended starting point for all readers.

Guide 2 – Layer Height, Infill, and Strength

Discover how strength is actually created inside a printed part. Learn why wall thickness often matters more than infill, why thinner layers are not automatically stronger, and how print orientation dramatically affects performance.

Essential reading for functional components.

Guide 3 – Tolerances and Dimensional Accuracy

Understand why printed parts do not always fit first time. Learn about shrinkage, hole sizing, axis accuracy, and how to design with predictable clearances.

Critical for assemblies, enclosures, and precision parts.

Advanced Functional Printing & Material Control

Guide 4 – Material Selection for Functional Parts

Explore how PLA, PETG, ASA, ABS, nylon and composites behave under heat, load, UV exposure and long-term stress. Learn why there is no “best filament” — only the correct material for the application.

Key to durability and reliability.

Guide 5 – Print Speed, Acceleration, and Motion Control

Learn how speed affects bonding, surface quality, and dimensional accuracy. Understand why controlled motion produces stronger and more predictable parts than simply printing faster.

Important for consistency and professional results.

Guide 6 – Surface Finish and Post-Processing

Understand how professional finishes are achieved through proper orientation, sanding, chemical smoothing and coatings. Learn why surface finish should be planned before printing begins.

Ideal for presentation-ready or customer-facing parts.

Design Strategy & Production-Level Thinking

Guide 7 – Designing for Efficiency and Cost Control

Learn how hollow structures, wall optimisation, support-free design and modular components reduce failures and improve scalability.

Essential for repeat projects and controlled production costs.

Guide 8 – Repeatability and Production Printing

Discover what makes 3D printing reliable over time. Learn about calibration discipline, material storage, environmental control and batch consistency.

Foundational knowledge for production printing and repeat orders.

Digital File Preparation & Workflow Control

Guide 9 – Understanding 3D Printing File Types: STL, 3MF, OBJ and G-code

Before printing begins, the correct file format must be chosen.

This guide explains:

The differences between STL and 3MF
When OBJ is appropriate
Why G-code is machine-specific
How file types affect scaling, colour, materials and collaboration
Why 3MF is increasingly preferred in modern workflows

Understanding 3D printing file formats improves reliability, reduces scaling errors, and supports better collaboration between designers and professional 3D printing services.

Essential reading before uploading files for printing.

3D Scanning and Digital Capture

Guide 10 – Why Doesn’t My 3D Scanner Capture Detail as Small as 0.02 mm?

Many 3D scanners advertise extremely high resolution values, such as 0.02 mm, but users often find that real scans do not appear to capture detail at that level.

This guide explains why this happens.

It explores the difference between scanner resolution and measurement accuracy, and how real-world factors influence scan quality.

Topics covered include:

Resolution vs accuracy in scanning
Surface reflectivity and material effects
Scanner distance and focus range
Movement and tracking stability
Lighting conditions
Mesh processing and software smoothing

Understanding these factors helps users achieve better scan results and set realistic expectations for scanning technology.

How to Use This Knowledge Hub

You can follow the guides in order for a complete structured learning pathway, or explore individual topics based on your current challenges.

Together, these guides provide a comprehensive understanding of:

3D printing strength optimisation
Dimensional accuracy and tolerances
Material performance
Motion control and print quality
Production reliability
File preparation and workflow best practice

This structured knowledge allows you to move from trial-and-error printing to predictable, professional results.
