01 — POWDER FUSION PROCESS
How Selective Laser Sintering Works
SLS fuses fine polymer powder particles using a precision laser beam. Unfused powder supports the part during printing, enabling total geometric freedom without support structures.
01
Chamber Preheating
The build chamber is preheated to optimal processing temperature before sintering begins.
02
Laser Sintering
A high-precision laser scans the 2D cross-section, sintering particles together into solid polymer.
03
Powder Recoating
A counter-rotating roller spreads an ultra-uniform new powder layer (typically 100–120 µm).
04
Support-Free Build
The surrounding loose powder cake naturally suspends overhangs, allowing complex interlocking geometry.
05
Depowder & Blast
Controlled cooling followed by automated bead-blasting and dye finishing for a uniform satin exterior.
02 — KEY ADVANTAGES
Key Advantages of SLS 3D Printing
When mechanical strength, complex fluid passages, and real-world durability are paramount, SLS Nylon delivers without compromise.
GEOMETRY
100% Support-Free
Manufacture internal conduits, complex lattice structures, hollow manifolds, and assembled-in-place ball joints without post-process support marks.
DURABILITY
Engineering Nylon PA12
True engineering thermoplastic properties. High impact resistance, excellent elongation at break, and chemical resistance to oils and fuels.
EFFICIENCY
3D Nesting & Batching
Dozens or hundreds of different parts can be packed across the entire 3D build volume, reducing unit costs for low-to-medium batch runs.
ISOTROPY
Near-Isotropic Strength
Laser thermal fusion creates exceptionally uniform tensile strength in all build axes, eliminating the Z-axis weakness common in standard filament printing.
03 — MATERIAL SYSTEM
Industrial SLS Polymer Formulations
Vadivam 3D provides verified industrial polyamide grades for rigorous mechanical and thermal applications.
STANDARD NYLON
Nylon PA12 (Polyamide 12)
Balanced mechanical profile with high tensile strength, excellent resistance to environmental degradation, and long-term fatigue life.
REINFORCED
Nylon PA12 Engineering Properties
High-performance polyamide engineering material offering elevated tensile strength, dimensional stability, and long service life.
FINISHING
Bead-Blasted & Black Dyed
Standard raw SLS parts have a fine grainy white/grey texture. We offer media blasting and deep matte black chemical dyeing for consumer finish.
