How to Use a 3D Printer (Beginner's Guide)

By the 3D Printer Lab editorial team · Updated 2026 · How we test & score

Getting started with a 3D printer feels daunting, but the workflow is straightforward once you've done it once. Here's how to go from a design to a finished print.

Quick answer

To use a 3D printer: get or design a 3D model, 'slice' it into printer instructions using slicing software, load your filament (or resin), level the bed on an FDM printer, then start the print and let it build up layer by layer. Most printers come with a test model so your first print is easy.

The basic workflow

Every print follows the same three steps: get a 3D model (download a ready-made one from a model-sharing site, or design your own in CAD software), slice it (the slicing software turns the model into layer-by-layer instructions and lets you set quality and supports), then print it (the printer builds the object up in thin layers).

Step by step

1. Choose a model - start with a free download or the bundled test file. 2. Slice it in the free software that comes with most printers, choosing layer height and whether supports are needed. 3. Load filament and, on an FDM printer, level the print bed so the first layer sticks. 4. Transfer the sliced file (by SD card, USB or network) and start the print. 5. Once finished and cool, remove the print and clean up any support material.

Tips for good first prints

Start with PLA filament - it's the easiest to print. Level the bed carefully, as most first-layer problems come from that. Use the printer's recommended temperatures, keep the first few prints small, and begin with the test model bundled with the machine before trying anything ambitious.

Frequently asked questions

Is a 3D printer hard to use?

There's a small learning curve, mainly around bed levelling and slicing settings, but modern printers are much easier than they used to be. After a few prints it becomes routine.

What software do you need for a 3D printer?

You need slicing software, which most printers include free. To design your own models you also need CAD software, but you can print ready-made downloads without it.

What should I print first?

Start with the test model that comes with your printer, then a simple free download. Small, simple prints in PLA are the best way to learn.
