🧠 What is 3D printing?

The3D printing is a manufacturing method that works by superposition of layers of material, from a digital model. Unlike traditional (subtractive) manufacturing, here, we adds material only where needed.

This technology is used both in industry and in the DIY and the model making, because it allows create quickly personalized, functional or decorative objects.


⚙️ How does a 3D printer work?

Here are the basic steps :

  1. 📐 Creation or download a 3D file (often in STL format)

  2. 🧠 Digital cutting of the model via a slicer which converts it into G-code

  3. 🖨️ Layer by layer printing, depending on the technology chosen (FFF, SLA, etc.)


🚀 The most used 3D printing technologies

  • FFF/FDM : Melted plastic filament (ideal for beginners and model making)

  • ALS : Liquid resin solidified by UV light (accuracy +++)

  • SLS/PBF : Powder fusion (for technical parts)

  • Material jet : Deposition of micro-drops (very high resolution)


🎯 Why is 3D printing ideal for model making?

The answer is simple: total creative freedom. No more compromises! Thanks to 3D printing, you can:

  • Create unique or missing pieces

  • Carry out ultra-detailed dioramas

  • Print custom accessories

  • Repair or reproduce broken elements

🧡 It’s more than a tool: it’s an extension of your imagination.
