Metal sintering

plasticautomotivefor the energy sector

Overview
Norck delivers selective laser sintering (SLS) services to produce precision, support‑free parts for functional prototypes, tooling and low‑volume production. SLS enables complex geometries, consolidated assemblies and durable mechanical performance for industrial applications.

Norck's Engineering Edge
Norck provides engineering support focused on manufacturability and repeatable performance, including material selection, process parameter optimization and part validation to meet application requirements.

Capabilities

• Industrial, support‑free printing for complex and consolidated geometries
• Durable nylon materials (PA11, PA12) and engineered blends such as glass‑filled and flame‑retardant grades
• Post‑processing: depowdering, dyeing, polishing and surface finishing
• Scalable workflow from quick‑turn prototypes to low‑volume manufacturing
• Design for Additive Manufacturing (DfAM) support to reduce material and improve performance
• Process optimization of laser energy density, layer height and build strategy for accuracy and finish
• Quality controls including dimensional inspection and mechanical testing

Materials Commonly Used

• PA11
• PA12
• PA GF (glass‑filled nylons)
• PA FR (flame‑retardant nylons)
• Ceramics
• Glass

Advantages

• Batch printing capability to produce many parts per build
• No support structures required, enabling internal features and consolidation
• Produces rigid, functional parts suitable for testing and end use
• Multiple finishing and coloring options via post‑processing

Disadvantages

• Extended cooling time required after build completion
• Post‑processing often needed to remove excess powder and improve surface quality
• Recycling and reuse of some powders require specific handling and reduce available yield

How SLS Fabrication Works
SLS builds parts layer‑by‑layer from a powder bed: the 3D model is sliced, each powder layer is deposited and selectively fused by a laser. After the build, parts cool in the powder bed before extraction; typical post‑processes include depowdering, surface smoothing, dyeing and mechanical finishing to meet dimensional and aesthetic requirements.
