Powder-Bed Fusion Technologies

Choose the Right Additive Process for Your Medical Devices

Both Electron Beam Melting (EBM) and Direct Metal Laser Sintering (DMLS) offer distinct manufacturing advantages. Greyack medical Co., Ltd evaluates your implant geometry and mechanical specifications to deploy the optimal technology.

Electron Beam Melting (EBM)

Utilizing high-power electron beams in a vacuum environment (GE Arcam EBM Q10plus), EBM maintains an elevated build temperature. This inherent thermal control stress-relieves components directly during production, minimizing residual stress and eliminating the risk of micro-cracking.

Ideal for high-volume press-fit acetabular cups & femoral components.

Build volume stacking for maximum batch output efficiency (200 x 200 x 180 mm).

Easy support removal reducing post-processing cycle times.

Direct Metal Laser Sintering (DMLS)

Combining precise laser optics with fine atomized metal powders, DMLS (DMP Flex 350) yields high-fidelity surface resolution, micro-detail accuracy, and exceptional mechanical density. It prints seamlessly in Ti64, CoCr, and 316L stainless steel.

High resolution for thin-walled surgical tools and complex robotics components.

Generates intricate conformal lattice geometries directly integrated with solid substrate.

Generous build envelope (350 x 350 x 350 mm) for R&D or serial production.

Enhanced Osseointegration

Engineered Porous Lattice Structures for Bone Ingrowth

Modern orthopedic implant design relies on advanced porous structures to achieve superior clinical outcomes. Additive manufacturing replaces traditional plasma spray coatings with monolithic, interconnected porous titanium structures manufactured in a single process step.

At Greyack medical Co., Ltd, our engineers utilize state-of-the-art lattice generation software to match target porosity, pore size distribution, and elastic modulus. This minimizes stress shielding while encouraging robust cell proliferation and long-term implant fixation.

Elimination of Delamination Risk: Porous layers are fused directly into the structural core.
Customized Anatomical Porosity: Tailored pore diameters (300–800 microns) for optimal vascularization.
Biocompatible Alloys: Certified Ti-6Al-4V ELI and Cobalt-Chrome powder bed stock.

Frequently Asked Questions

Additive Manufacturing Questions from OEM Sourcing Teams

Which 3D metal printing technologies does Greyack Medical utilize for medical components?

Greyack medical Co., Ltd operates both leading powder-bed fusion platforms: Electron Beam Melting (EBM) via GE Arcam Q10plus and Direct Metal Laser Sintering (DMLS) via DMP Flex 350. This dual capability allows us to select the optimal additive technology based on implant geometry, material specification, and surface finish requirements.

What materials are certified for additive manufacturing of orthopedic implants?

We manufacture additive components using medical-grade Titanium alloys (Ti-6Al-4V ELI), Cobalt-Chrome (CoCr), and 316L Stainless Steel, all thoroughly validated for mechanical strength, biocompatibility, and chemical cleanliness under ISO 13485 standards.

How do 3D printed lattice structures benefit orthopedic osseointegration?

3D additive manufacturing allows the creation of monolithic porous lattice structures that mimic natural cancellous bone. These engineered surfaces promote rapid bone in-growth and osseointegration, eliminating the risks of delamination associated with conventional plasma spray coatings.

What quality documentation is provided with 3D printed medical parts?

Every shipment includes full powder traceability, chemical certification, mechanical test results, density verification, CMM inspection reports, and validated post-processing heat treatment/passivation records suitable for inclusion in FDA 510(k) and MDR regulatory submissions.
