Unlock your manufacturing potential with Arcam EBM metal 3D printing
Metal additive manufacturing is revolutionizing the way the industry approaches the production of complex parts, and Electron Beam Melting (EBM) Technology developed by Arcam (now part of GE Additive) is leading the way. The technology harnesses the precision of electron beams in a high-temperature vacuum environment to transform metal powder into fully dense, high-performance parts. For industries that demand uncompromising structural integrity, including aerospace, medical implants and energy, Arcam EBM is rewriting the rules of design and manufacturing.
How Arcam EBM is changing metal manufacturing
At its core, Arcam EBM uses a focused electron beam to melt and fuse fine metal powders, building parts layer by layer. Unlike laser-based methods (SLM/DMLS), EBM operates in a vacuum at temperatures close to 1,000°C, allowing it to:
- Reduce residual stress: High-temperature environments minimize thermal gradients, virtually eliminating deformation and cracking of large or complex geometries.
- Excellent material properties: Parts reach close to theoretical density (>99.9%), and mechanical properties often exceed those of forged equivalents.
- Efficiency improvement: Due to the electron beam’s rapid scanning capabilities and ability to melt multiple points simultaneously, build speeds reach 55–80 cubic centimeters per hour.
- Recycled powder: The unmelted powder undergoes minimal degradation under vacuum and heat, allowing for high reuse rates (>95%), significantly reducing material costs.
Why industries choose Arcam EBM
aerospace: Titanium alloy (Ti6Al4V) machined by EBM offers excellent strength-to-weight ratio, fatigue resistance and thermal stability – enabling lighter aircraft engines with complex internal cooling channels not possible with conventional milling.
Medical orthopedics: This technology creates porous titanium implants (such as spinal cages) that mimic the natural porosity of human bone. This promotes osseointegration while maintaining robustness—bioefficiency verified as an FDA/CE certified product.
Energy and Automotive: Inconel 718 components are designed to withstand the extreme temperatures of turbine blades and exhaust systems. Production cycles are reduced from months to days without compromising durability.
Pushing the boundaries of materials science
Arcam EBM supports advanced alloys tailored to specific needs:
- Titanium grade: Ti64, TiAl (titanium aluminide), lightweight and heat-resistant.
- Nickel superalloy: Inconel 625/718 corrosion resistant parts.
- Refractory metal: Tantalum is chemically stable.
The material’s versatility allows engineers to optimize designs for stress distribution, thermal management, or biocompatibility without the constraints of traditional manufacturing.

Frequently Asked Questions (FAQ)
Question 1: How does Arcam EBM compare to SLM/DMLS?
EBM utilizes electron beams (not lasers) and operates in a high-temperature vacuum. This reduces residual stresses, enhances ductility, enables faster builds, and minimizes post-processing such as stress relief. SLM excels in detail; for larger, thicker parts, EBM dominates in robustness.
Q2: What are the typical tolerances and surface finishes?
Original EBM parts have tolerances of ±0.2–0.5%. The finished surface range is Ra 20–35 μm. Shot peening, machining or electrochemical polishing allows fine-tuning of smoothness to meet hydraulic, biomedical or cosmetic needs.
Q3: Is Arcam EBM cost-effective for mass production?
Yes, especially for aerospace and medical equipment in quantities of 500-5,000 pieces. The powder reuse rate exceeds 95%, and the material cost is reduced by about 40% compared with SLM. Layer heights up to 200 µm significantly reduce build times.
Q4: Which industries benefit the most from EBM?
Highly demanding industries take advantage of its strengths: aerospace (turbine components, fuel nozzles), orthopedics (implants), energy (heat exchangers) and motorsport (lightweight drivetrain components).
Q5: Can Honglaite process customized materials such as tungsten or cobalt-chromium alloy?
Absolutely. Our facilities can accommodate specialty alloys (including GRCop-84 copper and tool steel) with customized thermal profiles. Contact us to discuss material requirements and validation protocols.
Q6: How does Hualite ensure quality?
Each batch undergoes spectroscopy, CT scanning, tensile/impact testing and surface analysis. We carry out ISO 13485/9001, AS9100 certification for our products and provide material test reports (MTR).
