SLM

Selective Laser Melting

SLM printing, or Selective Laser Melting, is an advanced metal 3D printing (Additive Manufacturing) process that uses a high-power laser to completely melt and fuse fine metallic powder layer-by-layer to build complex, high-density, functional metal parts from CAD data, offering high precision and strong mechanical properties for industries like aerospace and medical. It's a form of Powder Bed Fusion (PBF), creating strong parts with near-full density, ideal for intricate designs and tooling without traditional molds.

Features:

High Strength & Durability: Prints fully dense metal parts with excellent mechanical properties
Complex Geometries & Lightweight Designs: Ideal for lattice structures, internal channels, and topology-optimized parts
Wide Range of Metal Materials: Stainless steel, aluminum, titanium, and nickel-based alloys
Scalability for Prototyping & Production: Efficient for both single parts and batch manufacturing

Available Materials:

Stainless steel 316LAluminum AlSi10MgTitanium Ti6Al4V grade 23Tool steel 1.2709Project-specific metals available upon request

Applications:

Aerospace & Automotive – Lightweight, high-strength componentsMedical & Dental – Custom implants and biocompatible partsTooling & Engineering – Wear-resistant tools and functional prototypesEnergy & Industrial – High-performance parts for extreme conditions
