A Beginner's Guide to 3D Printing

Welcome to the world of 3D printing!

Imagine being able to make anything - from cable holders, table decorations, to functional home improvement pieces - all from the comfort of your own home. 3D printing makes it possible. This guide helps you understand the basics of 3D printing, choose the right equipment, and make your first successful 3D print.

1. What is 3D printing?

3D printing (additive manufacturing) is a process in which objects are made layer by layer, based on a digital model. Most often it uses plastic materials, but there are also variants with metal, resin and other materials.

For hobbyists, the most common choice is FDM technology , where plastic filament is melted and applied layer by layer until the finished object is created.

2. How does a 3D printer work?

The printer works by melting the plastic filament and applying it precisely according to the given coordinates. The key parts are:

  • Hotend – melts and extrudes the filament
  • Extruder - pushes the filament into the hotend
  • Heating pad - enables better adhesion of the model
  • Stepper motors – move the head and platform in three axes (X, Y, Z)
  • Control panel – controls all printer functions

Modern printers, such as those from the Bambu Lab series, come with pre-calibrated systems, automatic leveling and Wi-Fi connectivity, making it much easier for beginners to take their first steps.

3. What do you need to get started?

3D Printer – A model that is easy to use, has automatic leveling and multi-color support is recommended.
Filament - PLA is the easiest to work with, does not require a closed chamber and has good print quality.
Software (slicer) – used to prepare models for printing.
Computer or phone - for processing models, sending files, controlling and monitoring the printer's operation.

Printers like the Bambu Lab A1 Mini offer an excellent balance between price, simplicity and quality, with additional features such as multi-colour printing and automatic calibration.

4. Model preparation software

In order for the printer to know what to print, you have to send it the so-called G-code file. That file is created using slicer software.

  • Modeling (optional):
    • Tinkercad – a free, simple tool for beginners
    • Freecad
    • Fusion 360 – a more advanced tool for technical models
    • Blender
  • Slicer software:
    • Bambu Studio - recommended software for Bambu Lab printers, simple and powerful
    • Cura or Orcasslicer - popular tools for other FDM printers

In the slicer you set:

  • Layer height and model fill (quality)
  • Printing speed
  • Support
  • Extruder and substrate temperature
  • Colors (if using the AMS system)
  • Many other parameters

5. Where to find models?

If you don't want to make your own models right away, you can download ready-made sites such as:

  • Printables.com
  • Thingiverse
  • MakerWorld – the official platform of the Bambu Lab community

6. The first printed item - step by step

  1. Choose a model - e.g. cable holder or simple decoration
  2. Import it into slicer - use Bambu Studio or other software
  3. Adjust parameters - use recommended values for PLA
  4. Send the file to the printer - via SD card, USB or Wi-Fi connection
  5. Start the press - follow the first layer and check if the model is well adhered to the substrate
  6. Finish and remove the model - let the base cool before removing

7. The most common mistakes and how to avoid them

  • The model does not stick to the surface.
    Solution : Wash the substrate with warm water and soap or wipe with alcohol. Be sure to use adhesive spray or glue and turn on the " brim " option
  • Stringing
    Solution : Reduce the temperature of the extruder, dry the filament before use, change the " retraction " parameters
  • Crumpled layers or deformations
    Solution : Make sure the nozzle is clean and use a quality filament
  • Improper printing in multiple colors
    Solution : If using an AMS system, check that all filaments are inserted correctly and colors are correctly assigned in the slicer

8. Next steps

Once you've mastered the basics, you can:

  • Learn 3D modeling and make your own designs
  • Experiment with different materials (PETG, TPU, ASA...)
  • Upgrade the printer (eg additional AMS module, upgrade nozzles)
  • Share your work on platforms like Printables and MakerWorld
