“Electron Beam Welding Technology is a thriving trend in the metal forming market.”

What are the upcoming technology trends in metal forming/ metal cutting? 

Cold Spray Additive Manufacturing (CSAM) is one technology co-developed with Australia’s CSIRO to capitalize upon and add value to Australia’s abundance of titanium reserves which can be termed under the upcoming technology trends in metal forming. CSAM is based on the deposition of metal powders at supersonic speeds to create industrial scale parts and complex surface coatings. Titomic of Australia leverages this patented process and material science to create high performance products and solves complex engineering challenges utilizing automation and additive manufacturing. 

3D Printing of Ceramic parts: Zirconia, HAP, alumina materials have been recently launched using laser SLA 3D Printing technology, made out of ceramic slurry developed in France by the company 3D Ceram. 3D Ceram is one of the leading providers of this technology in the 3D Ceramic Printing industry. 

What are the latest offerings in the market with respect to standard format laser machines? 

The latest offerings in the market, CSAM technology, are well equipped with advanced offerings, some of them listed below: 

• Creates parts at high speed, drastically reducing end-to-end production time without any need for an inert environment, no size constraints and minimizes post-production machining. 
• Large-scale manufacturing properties featuring dissimilar metals and composites. 
• Viable input costs to rival traditional manufacturing 
• Allows the manufacture of near-net shape parts, meaning parts are additively manufactured near their final tolerance (near-net shape) and may be machined by up to 10 percent along with drastically reducing lead times, machine time and material waste. 

Incorporated in 2014, Titomic was created to commercialise Titomic Kinetic Fusion, or TKF or (CASM), based on the deposition of metal powders at supersonic speeds to create industrial scale parts and complex surface coatings. Titomic leverages this patented process and material science to create high performance products and solves complex engineering challenges utilising automation and additive manufacturing. Some of the capabilities of TKF are listed below: 

• Prototyping, short runs and scalable volume along with Large Production Volumes 
• Low Material Cost than all AM / 3D Printing, less Material than conventional methods, faster production than conventional and AM 
• Machined or rough surface finishes along with medium fabrication costs. 

The applications that are possible through this technology serve a wide variety of sectors such as aerospace, research, defense, biomedical field and diversified industries such as electronic insulation, heat exchangers, foundry cores, medical tooling etc. 

Since 2017, after its integration into the Sinto group, 3DCeram has chosen to develop a range of 3D printers for technical ceramics, with 4 models, meeting the specifications of customers from industry, research centers and laboratories, etc. 

3DCERAM SINTO, today, is specialized in three areas:
