3R Additive Technology Company Limited is a leading one-stop solution provider for advanced metal manufacturing and precision processing, rooted in China. Specializing in additive manufacturing (3D printing) and integrated traditional metalworking technologies, we deliver high-quality custom metal parts and end-to-end manufacturing services to global industrial clients across aerospace, automotive, medical, electronics, energy, and other high-demand sectors.Our Core Capabilities & Offerings
We cover the full lifecycle of metal manufacturing, with comprehensive services and products including:
1. Additive Manufacturing (3D Printing) Technologies
Selective Laser Melting (SLM) & Selective Laser Sintering (SLS): Advanced metal 3D printing for complex lightweight structures (e.g., lattice/hollow parts) with >90% material utilization.
Metal 3D Printing Prototypes & Production: Custom metal prototypes, 3D printed moulds, and end-use parts for rapid R&D and small-batch production.
Industrial Metal 3D Printers: Supply of professional-grade metal 3D printing equipment for in-house manufacturing needs.
2. Precision CNC Machining & Manufacturing
CNC Machining / CNC-Fertigung: Multi-axis (including 5-axis) CNC milling/turning for micron-level precision components (tolerance down to ±0.001mm).
CNC Manufacturing: Full-process CNC production for precision parts, covering prototype manufacturing and mass production.
Laser Cutting: High-precision laser cutting for metal sheets and custom components.
3. Metal Forming, Casting & Forging
Metal Injection Moulding (MIM / Metallspritzguss): High-volume production of micro-precision metal parts (e.g., 5G connectors, medical implants) with tight tolerances (±0.1–0.3mm).
Casting Solutions: Sand casting, die casting (Druckguss), precision casting (Präzisionsguss), and precision die casting for large/complex metal components.
Forging Services: Cold forging (Kaltschmieden) and custom forging work (Schmiedearbeiten) for high-strength structural parts (30%–50% higher strength than castings).
Tube Bending (Rohrbiegearbeiten): Weld-free CNC tube bending for automotive cooling/exhaust pipes, energy transmission pipelines, and medical tubing systems.
4. Surface Finishing & Advanced Processing
Polishing Services: Mechanical/chemical polishing, ultrafine polishing (Feinstpolieren), and mirror finishing (Ra ≤ 0.02μm) for medical/optical/aesthetic metal parts.
Polishing Equipment: Supply of metal polishing machines (Metallpoliermaschinen) and polishing apparatus (Poliergeräte).
Powder Metallurgy (Pulvermetallurgie): Near-net shaping for high-efficiency, low-waste metal parts (e.g., micro-motor components, sensor cores).
Powder Coating (Pulverdecklackierung): Corrosion-resistant surface coating for durable metal components.
Welded Parts (Schweissteile): Custom welded metal components for structural applications.
5. Specialized Materials & Precision Components
Metal Powder (Metallpulver): High-purity metal powders for additive manufacturing and powder metallurgy.
Titanium Alloys (Titanlegierungen) & Titanium Parts (Titanteile): Medical-grade and aerospace-grade titanium components for high-performance applications.
Precision Parts Manufacture (Präzisionsteilelieferung): Custom precision metal parts tailored to client specifications (supports 2D/3D drawings in STEP/IGS format).
Rapid Prototyping: Fast prototype development for product validation and R&D acceleration.

Industry Applications
We provide tailored metal manufacturing solutions for core industrial sectors:
Aerospace: Lightweight 3D printed components, high-strength forged parts, and precision CNC machined parts (compliant with AS9100 standards).
Automotive: Forged/cast structural parts, MIM sensor components, and tube bending for exhaust/cooling systems.
Medical: FDA-compliant 3D printed implants, MIM dental components, and precision polished medical devices.
Electronics & 3C: Micro-precision MIM/CNC parts for 5G connectors, foldable devices, and consumer electronics.
Energy: Forged wind power spindles, precision cast pump bodies, and corrosion-resistant tube bending for oil/gas/nuclear applications.
