Hey Max — this is your bench manual for turning a spool of plastic into real objects. No fluff, no logins, no internet required. Just the stuff that actually helps you get a clean first print.
FIG. 01 — CARTESIAN FDM
A 3D printer builds objects from the bottom up by laying down melted plastic in thin layers — usually about a fifth of a millimetre thick — and stacking hundreds or thousands of them until a shape appears.
The most common kind, and the one this guide is about, is called FDM — Fused Deposition Modeling. A motor pushes a plastic string (filament) into a hot metal nozzle. The nozzle melts it and draws each layer like a tiny hot glue pen on rails. You design or download a model, a program called a slicer chops it into layers, and the printer follows those instructions one line at a time.
Getting started, slicer settings, filament types, and a troubleshooting table for when prints go wrong.

Open resources →The nozzle should be one sheet of paper away from the plate, everywhere. This single thing fixes most failures.
Heat the nozzle to ~200 °C for PLA, feed the spool until plastic oozes out clean.
Drop a .stl into your slicer, pick "0.2 mm standard", and export the .gcode.
Stay for the first layer. If it sticks flat and even, the rest almost always works out.
Don't chase a perfect print on day one. Chase a finished one. A slightly ugly object that came off the bed in one piece teaches you more than a fancy model that failed at layer 3.
