3D printing, also known as additive manufacturing, is an innovative technology that turns a digital model into a physical object, layer by layer.
To learn more about the different machines, check out our range of 3D printers.
This revolutionary method is gaining traction across many sectors, from industrial prototyping to customized object creation.
What is 3D printing?
3D printing involves creating three-dimensional objects by successively stacking layers of material, typically plastic, but also metal, resin, or other substances. This technology relies on a digital model designed using computer-aided design (CAD) software.
Unlike traditional machining processes that remove material, 3D printing adds material, layer by layer, to bring a digital model to life.
Today, this technology is becoming increasingly accessible, finding its way into both hobbyist workshops and industrial production lines.
How does a 3D printer work?
The 3D printing process consists of several key steps:
- Designing the 3D model: It all starts with creating a digital 3D model using modeling software such as Blender, Fusion 360, or Tinkercad. You can also download ready-to-print models from platforms like Thingiverse.
- Slicing the model: The 3D file is then sliced into thin layers using a software called a “slicer.” This software generates a code (G-code) that will guide the printer.
- Layer-by-layer printing: The printer successively deposits layers of material – plastic, resin, powder, depending on the technology – until the final object is formed.
The main 3D printing technologies
There are several 3D printing methods, each suited to specific needs:
| Technology | Principle | Common Materials | Applications |
|---|---|---|---|
| FDM (Fused Deposition Modeling) | Melting and extruding thermoplastic filament | PLA, ABS, PETG | Prototyping, home use |
| SLA (Stereolithography) | Curing liquid resin with a laser | Photopolymer resins | High precision, jewelry, dental |
| SLS (Selective Laser Sintering) | Laser sintering of powdered material | Nylon, TPU | Technical parts, small series |
| DLP (Digital Light Processing) | Photopolymerization with a light projector | Liquid resins | Jewelry, dental prosthetics, miniatures |
| MJF (Multi Jet Fusion) | Binder jetting and thermal fusion | PA 12, PA 11 | Functional parts, serial prototyping |
| LCD (Masked Stereolithography / MSLA) | UV light curing through a masked LCD screen | UV resins | Miniatures, prototyping, home use |
| DMLS (Direct Metal Laser Sintering) | Direct laser melting of metal powder | Aluminum, titanium, stainless steel | Aerospace, tooling, implants |
| WAAM (Wire Arc Additive Manufacturing) | Metal wire deposition via electric arc (similar to MIG welding) | Steel, titanium, aluminum | Large metal parts, heavy industry |
Why is 3D printing so appealing? Its strengths… and countless applications
3D printing is attracting a growing number of users, both professionals and hobbyists, because it is revolutionizing design and production methods. Here’s why this technology continues to gain traction:
Extreme customization
Each part can be tailor-made – dimensions, shape, function… It’s the perfect tool for unique projects or small production runs.
Lower costs and faster turnaround
Need to create a prototype or final part in just a few hours, with no tooling or intermediaries? 3D printing makes it possible – and at a lower cost.
Unlimited complexity
Organic shapes, internal lattice or hollow structures – once impossible to manufacture – are now easy to produce.
Local and sustainable production
Producing on demand, locally, reduces inventory, waste, and transportation. 3D printing supports a more responsible and sustainable approach.
Main application fields of 3D printing
| Sector | Examples of Use |
|---|---|
| Medicine | Custom prosthetics, dental implants, surgical tools, tissue printing (bioprinting) |
| Aerospace & Automotive | Lightweight parts, performance improvement, rapid prototyping or spare parts manufacturing |
| Architecture & Design | Models, furniture, lighting, custom decoration |
| Education | Educational models, research projects, science communication |
| Industry | Tooling, functional parts, on-demand production |
| Hobbies & DIY | Custom figurines, cosplay accessories, gadgets, everyday objects |
