UV printing safety: light, ink and cleaning fluids
UV printing looks clean and harmless — "it just prints" — but it has real hazards of its own: light, uncured ink, and cleaning solvent. Meet them before you get careless.
Choosing a UV printer: desktop, flatbed, or roll-to-roll
A spec sheet shouting "2880 dpi!" tells you nothing about what actually matters day to day. Here's what really decides a UV printer purchase.
Choosing a DTF printer: converted desktop, purpose-built machine — or not buying at all
Before talking printheads and dpi numbers, there's a question nobody asks out loud: do you even need to buy a printer, or is it better to order ready-made transfers from a service?
The essential 3D-printing toolkit: what to buy first, what can wait
The internet will sell you dozens of 'essential' add-ons for a new printer. In practice you need a small handful to start well — here's the honest list.
Choosing your first 3D printer: what actually matters vs what just shouts loudest
A printer's spec sheet brags about top speed and peak temperature. In practice, four completely different things decide what your first month actually looks like — and they're rarely in the bold print.
Preparing files for DTF: resolution, color, transparency — and the opposite trap from sublimation
If you're coming from sublimation, there's a total reversal that trips up a lot of makers: there, white never prints. In DTF, white does print — with actual white ink. Confusing the two ruins a whole design.
Preparing a file for UV printing: color mode, white/varnish layers and resolution
A file that's ready for UV printing differs from a sublimation-ready file starting with color mode. How to prep white/varnish layers and resolution correctly.
Your first DTF print: from file to shirt, step by step
Every step you've read about in this series converges into one moment: print, powder, cure, press, peel. Here's exactly what to do the first time, and what 'right' looks like at each step — including the three mistakes almost every beginner makes.
3D printer safety and placement: heat, fumes and fire, without the drama
A 3D printer can run for hours while you're not in the room. That's convenient — and exactly why it's worth knowing what's actually risky and what isn't, without panic and without complacency.
What home FDM printing is genuinely good at — and what it isn't
A 3D printer isn't a magic machine that makes anything you imagine. Here's an honest look at what it genuinely excels at, and what to skip expecting — so your expectations start out right.
3D printer anatomy: what every part actually does
Hotend, extruder, gantry, ABL probe — words that sound like a foreign language the first time you read a printer spec sheet. Here's a clear, short dictionary, so the rest of the course speaks a language you actually understand.
FDM vs resin: the two home 3D-printing technologies, honestly compared
Two technologies both called '3D printing' that barely resemble each other — not in process, not in safety, not in what each is actually good for. Here's the honest comparison to help you decide before buying.
How 3D printing actually works: from filament to solid object
Watch a 3D printer work for the first time and it feels like a magic trick: a thin plastic wire goes in, a solid object comes out. No magic — just one simple idea the rest of this course builds on.
Downloaded a 3MF from CraftWizard? Here's what to do with it
You designed a keychain or a sign, hit download, and got a file with a strange .3mf extension. Here's exactly what it is, how to open it in every slicer, how to assign colours even without an AMS, and what to check before you hit print.
Which nozzle diameter should you use? A complete guide to nozzle size in FDM printing
Almost every printer ships with a 0.4mm nozzle, and most people never ask whether that's the right choice. Here's what each nozzle diameter actually gives and takes — including when a 0.6mm beats the stock 0.4mm on both time and strength.
Speed that looks free and isn't: what each shortcut actually costs, and what's really limiting your printer
Some settings promise faster prints with zero cost, and that's just not true. Here's exactly what each shortcut costs, and how to tell whether the real ceiling is your hotend's melt rate or the printer's own frame.
Print faster without losing quality: where the time really goes, and what buys speed for nearly free
The slicer says 14 hours, it's already 9pm, and you want it done tonight. The good news: some speed really is free — it costs nothing in quality. Here's where the time actually goes, and which settings change that without giving anything up.
How CraftWizard differs from automatic model generators
MakerWorld's sliders, AI text-to-3D, and raw OpenSCAD each solve a real problem. An honest comparison — including when they're the better choice, not us.
STL, 3MF, STEP, OBJ: which 3D file format fits which job
STL, 3MF, OBJ, STEP, AMF, G-code — they're all 'a 3D file', and they're all completely different in what they can actually carry. Here's what each format gives you, what it can't, and which one to pick for which job.
Which filament should you buy? A practical guide to FDM material types
Standing in front of a shop page or an eleven-filament AliExpress listing and not sure what's actually different? Here's what each material is genuinely good at, bad at, and the print/drying temperatures that matter — including the Israeli-summer failure modes.
Tuning support settings: the Z distance, density and interface that decide whether supports peel off or fuse on
You know you need supports, but the slicer settings look like a wall of cryptic numbers — and each software calls them something different. Here's exactly which settings matter, what each one does, and what it's called in Bambu Studio/Orca, Cura and PrusaSlicer.
How to price a 3D print for sale
How much should you charge for a keychain that used half a shekel of filament? The answer isn't 'half a shekel times two.' Here's a full formula that includes what most beginners forget entirely: machine time, failure rate, and your own labor.
Tolerances in 3D printing: designing parts that actually fit together
You modeled a 10mm hole, printed it, and the part just doesn't go in — or goes in too loose and falls out. The problem is almost never the software. Here's why your printer doesn't print the exact number you typed, and what clearance to leave for each kind of fit.
Print orientation: the single decision that decides whether your part breaks
The same STL file, printed in a different orientation, can survive a drop or snap from a light tug. Here's why FDM layers are weak specifically across the vertical axis, and how orientation makes that weakness almost irrelevant.
