What exactly is 3D printing?
✓ Essential definition:
3D printing is an additive manufacturing technology that creates three-dimensional objects by layering successive layers of material (plastic, resin, metal, composite) according to a 3D digital model. Unlike subtractive manufacturing (machining, laser cutting), 3D printing adds material layer by layer, virtually eliminating production waste.

Fundamental principle of 3D printing
The 3D printing process is based on a simple yet revolutionary principle: transforming a digital 3D file (STL, OBJ, 3MF) into a tangible physical object. The 3D printer deposits or solidifies material layer by layer, with precision reaching 0.05 mm depending on the technology used. To understand each step of the process in depth, consult our detailed guide on how 3D printing works.
This additive method radically opposes traditional subtractive techniques where material is removed from an initial block (milling, turning, cutting). 3D printing enables creation of complex shapes impossible to machine, with material waste nearly zero (generally less than 5%).
From home printer to PAMI3D large format
While domestic 3D printers are generally limited to volumes of 20×20×20 cm, large-format 3D printing pushes these limits dramatically. PAMI3D has equipment capable of printing up to 110×110×170 cm in a single piece, and can assemble even larger elements for architectural, industrial, or event projects.
This exceptional capacity opens infinite possibilities for professionals: 1:1 scale automotive prototypes, giant 3D POS displays for trade shows, immersive architectural models, personalized scenic decors... All with professional finishes (painting, powder coating, customization) guaranteeing exceptional rendering.
Large-format 3D printing in progress - FDM technology filament deposition layer by layer
How does a 3D printer work?
✓ Simplified operation:
3D printing works in 4 steps: creating 3D file (CAD or scan), slicing (digital cutting into thin layers 0.1-0.3 mm), layer-by-layer printing through melted material deposition (FDM) or resin polymerization (SLA), then finishing. Duration: 2 hours to 5 days depending on size and complexity.
The 3 major 3D printing technologies
FDM - Fused filament deposition
FDM (Fused Deposition Modeling) technology is the most widespread and the one mastered by PAMI3D for large format up to 170 cm. A plastic filament (PLA, PETG, ABS, TPU) is heated to 180-260°C then deposited layer by layer by a mobile nozzle.
Advantages: Economical, fast, wide choice of materials, ideal for large format
Applications: Prototyping, POS displays, architecture, industry
SLA - Resin stereolithography
SLA (Stereolithography) technology uses a UV laser to polymerize (solidify) a photosensitive liquid resin layer by layer. Exceptional precision up to 0.025 mm for ultra-fine details and smooth surfaces.
Advantages: Extreme precision, smooth finish, complex details
Applications: Jewelry, dental, detailed models, aesthetic prototypes
SLS - Selective laser sintering
SLS (Selective Laser Sintering) uses a powerful laser to locally fuse a powder (Nylon PA12, TPU) layer by layer. No support required, unfused powder naturally supports overhanging parts.
Advantages: Resistant parts, no supports, complex shapes
Applications: Functional parts, tooling, small industrial series
