What you'll learn

How it worksWhat actually happens while printing, which technology suits you, what each part does, and what you can genuinely make.
Machine and materialsChoosing a first printer, which filament to buy, nozzle sizes, and the small tools that matter.
From file to printWhere models come from, how the formats differ, what to do with a downloaded file, and your first print.
The fundamentalsLayer height, walls and infill, bed adhesion, orientation and strength, and everything about supports.
Quality, speed and problemsDiagnosing and fixing problems, printing faster without paying for it, calibration and maintenance.
What's nextPost-processing, multi-colour printing, embedding magnets, and turning it into something you sell.

3From file to printWhere models come from, how the formats differ, what to do with a downloaded file, and your first print.6 lessons

Where to get 3D models: download, generate, or design your own
STL, 3MF, STEP, OBJ: which 3D file format fits which job
Downloaded a 3MF from CraftWizard? Here's what to do with it
What a slicer actually is, and why the same file prints differently on two machines

4The fundamentalsLayer height, walls and infill, bed adhesion, orientation and strength, and everything about supports.8 lessons

Layer height in FDM 3D printing: what it costs you in time vs what it buys in quality
Walls vs infill: what actually makes your 3D print strong
First layer and bed adhesion: why prints won't stick (and how to fix it)
Print orientation: the single decision that decides whether your part breaks
Supports, overhangs and bridging: when your printer needs help
Tuning support settings: the Z distance, density and interface that decide whether supports peel off or fuse on
Removing supports without wrecking the part: tools, order of operations and finishing
Soluble supports: PVA vs HIPS, and whether it's worth the hassle

5Quality, speed and problemsDiagnosing and fixing problems, printing faster without paying for it, calibration and maintenance.6 lessons

Solving common FDM 3D-printing problems
Calibrating your printer: first layer, flow, temperature and retraction — and in what order
Print faster without losing quality: where the time really goes, and what buys speed for nearly free
Speed that looks free and isn't: what each shortcut actually costs, and what's really limiting your printer
Tolerances in 3D printing: designing parts that actually fit together
3D printer maintenance: what to check every month
