Push for Large Size Metal AM Parts

Melbourne based Australian startup developed Titomic Kinetic Fusion (Cold Spray of powder)) to produce load-bearing 3D forms from metallic and non-metallic powder feedstock. The 2 co-inventors, Mr. Jeff Lang and Professor Richard Fox, explored IP spraying metal powders at supersonic speeds onto a scaffold to build a 3D object. This was found to be a patentable application. The CSIRO patent was licensed and a new company, Titomic, was established to commercialize this technology.

Why Titomic Kinetic Fusion

• At least 5 times faster than fastest Metal AM method out there.
• Fuse dissimilar metals for large seamless structures with enhanced engineered properti.
• Stronger structures without welding, folding or bending weak points.
• Production volumes without extensive production tooling.
• Industry-leading build rates, faster manufacturing time & speed to market.
• More efficient use of energy and resources, saving production costs. 

  Observations

• As this is a cold-welding operation, it is to be seen that what is the smallest feature it can print.
• Accuracy of manufactured parts.
• Extensive post processing may require.
• More accurate features may require machining.
• Company is targeting large size parts specific to Aerospace applications where cost of Titanium is a concern. Big portion of the metal is lost when applying subtractive methods for manufacturing.

Additive Helping Subtractive

Milling Tool Body Manufactured by Additive 

Tool manufacturer SANDVIK COROMANT showcased a Milling cutter body (Light Weight CoroMill 390) manufactured by additive.

Advantages:

• Light Weight.
• Shorter tool body length.
• Better tool life.
• Silent Tools™ damping technology offers high productivity
  when machining with long overhangs. 

According to Sandvik "When designing lightweight CoroMill® 390, material has been

tactically removed to create the optimal cutter design for minimizing mass. This makes it more compact and significantly lighter than a conventional cutter"

Applications:

• Lightweight CoroMill® 390 is designed for long reach face milling, deep shoulder and side milling, cavity milling and slot milling.
• To be used at depths more than four times the cutter diameter combined with Silent Tools™ milling adaptor.
