Make Metal Parts Faster & Cheaper Than Ever with Electron Beam Additive Manufacturing (EBAM®) Systems or Services

3D printing has had an undeniable impact on the manufacturing world. Parts made faster, with less material waste, reduced machining time, and shorter time-to-market are just some of the benefits attainable with 3D printing (a.k.a. Direct Digital Manufacturing).

Metal Additive Manufacturing with Sciaky's EBAM<sup>®</sup> Technology

Sciaky’s Electron Beam Additive Manufacturing (EBAM) is a one-of-a-kind metal additive manufacturing technology that delivers on the key benefits mentioned above and excels at producing large-scale, high-value metal parts. It’s no secret that large-scale forgings and castings can take many, many months to complete. EBAM, on the other hand, can produce high quality, large-scale metal structures, up to 19’ in length, made of titanium, tantalum, and nickel-based alloys in a matter of days, with very little material waste.

In addition, the EBAM process can be used in any phase of the product life cycle: from rapid prototypes and production parts to repair and remanufacturing applications.

How does EBAM® work?

additive manufacturing CAD finish

Here’s the short version: Starting with a 3D model from a CAD program, Sciaky’s electron beam (EB) gun deposits metal (via wire feedstock), layer by layer, until the part reaches near-net shape and is ready for finish machining. Sciaky’s IRISS® (Interlayer Real-time Imaging & Sensing System) is a patented Closed-Loop Control that provides consistent part geometry, mechanical properties, microstructure, metal chemistry and more from the first part to the last. Gross deposition rates range from 7 to 20 lbs. (3.18 to 9.07 kg) of metal per hour, depending upon the selected material and part features. When it comes to producing large, high quality metal parts, no other metal additive manufacturing process in the world works faster -- or is more cost-effective -- than EBAM.

Plus, with an EBAM dual wirefeed system, you can combine two different metal alloys into a single melt pool, managed with independent program control, to create “custom alloy” parts or ingots. You also have the option to change the mixture ratio of the two materials, depending upon the features of the part that you are building, to create “graded” parts or structures. Furthermore, you can alternate between different wire gauges for finer deposition features (thin wire) and gross deposition features (thick wire). These unique benefits are exclusive to the EBAM dual wirefeed process and are not available with any other metal additive manufacturing process in the market.

How Large of a Part can you Build with EBAM®?

Wondering what the most effective size range for EBAM parts is? Parts and structures up to 19 ft. x 4 ft. x 4 ft. (5.79 m x 1.22 m x 1.22 m) – or round parts up to 8 ft. (2.44 m) in diameter – can be produced with Sciaky’s EBAM machines. While large-part metal additive manufacturing is our specialty, EBAM can also be effective for smaller-scale parts and applications, too. In general, parts starting around 8 in. ³ (203³ mm) and larger are the best candidates for the EBAM process.


Materials

The best material candidates for EBAM applications are weldable metals that are available in wire feedstock. These materials include:

  • 2319, 4043 Aluminum
  • 4340 Steel
  • Zircalloy
  • 70-30 Copper Nickel
  • 70-30 Nickel Copper

 



Benefits of Choosing EBAM for Additive Manufacturing

  • Reduces material costs, lead times, and machining times (as much as 80%) vs. conventional manufacturing
  • The fastest, most cost-effective Additive Manufacturing process in the market for producing large metal parts
  • IRISS® Closed-Loop Control Technology ensures process repeatability and traceability (real-time adaptive control)
  • The widest range of material options for large-scale metal applications
  • The Big Metal Experts: Sciaky offers the largest build envelope in the world for 3D printed metal parts
  • The widest range of commercially-available metal Additive Manufacturing systems (in terms of work envelope scalability)
  • EBAM’s exclusive dual wirefeed process allows you to feed two different metal alloys into a single melt pool to create parts made of custom alloys; It also allows designers to vary alloy mixtures to produce graded parts; Graded parts can also be produced by switching from thin wire (fine deposition) to thick wire (gross deposition) feedstock
  • EBAM works exceptionally well with refractory alloys and produces significantly less material waste (a big cost-savings advantage!) – Plus, wire feedstock is significantly less expensive than powder feedstock, it is easier to store, and it isn’t highly flammable like some powder feedstocks
  • With EBAM’s pure vacuum environment, the process doesn’t require the use of Argon or any inert gas for part shielding
  • Start 3D printing parts in as little as 12 minutes; While EBAM pump down times can vary by chamber size and application, it is still, by far, the fastest metal AM process in the market when you consider EBAM’s industry-leading deposition rate
