There have been a lot of informative developments in additive making coming out of China not long ago – in the areas of architecture, in space travel, in medicine, and actually in environmental protection. The Chinese 3D printing industry is expanding swift after a long period of stagnation. As we all understand, one of the largest keys to continued growth in the 3D printing market is the continued development of metal 3D printing, and it looks as yet China is right on top of that area as well. At the end of last week, researchers of Huazhong University of Science and Technology revealed that they have turn it intod a new method of metal 3D printing – one that may eliminate several of the issues that yet plague much of the innovation.
Zhang Haiou, leader of the 3D printing innovation research team at the university, has been developing the method for over a decade along with his man researchers. Dubbed “intelligent micro casting and forging,” the technique combines aspects of traditional metal casting and forging innovation along with 3D printing to turn it into stronger, additional ductile and stable parts. According to Zhang, the method eliminates common problems such as porosity, cracking, and the crumbling or dropping of futilized materials due to gravity or rapid heating and cooling.
“In the past, conventional 3D printing has been fatally flawed in the next areas. First, without forging, metal parts have a serious accident of wearing. Second, the performance of 3D printed parts has not been high. A third problem is the presence of pores and unfutilized portions and the fourth is that via a laser or electron beam as a heat source is quite costly,” he said.
The printing device, called the Micro Forging & Casting Sync Composite Device, is may already being utilized to manufacture parts – namely, titanium joints – for China’s stealth jet fighter planes. The research team expects that the innovation, that can in addition be utilized to manufacture thin-walled parts without excess material, can have a big impact on the aerospace industry, as well as the car, medical and general making sectors. It should donate a worthwhile boost to the Made in China 2025 initiative, that aims to update and overhaul the country’s making industry with a focus on high end and green innovation.
According to the team, intelligent micro casting and forging uses metal wire that is 90 percent cheaper than the powders utilized in many metal 3D printing techniques. It is in addition 80 percent additional efficient than SLM printing, and can turn it into parts up to 5.5 x 4.2 x 1.5 m, with a surface roughness of 0.02 mm.
Whilst several hybrid technologies have been developing not long ago, combining 3D printing devices with CNC machines and other methods of production, this seems to be the initially time 3D printing has been merged with forging and casting. Parts turn it intod with the intelligent micro casting and forging innovation can be additional reliable and longer-lasting, the team says, and they’ve may already been awarded multiple patents, both in China and internationally. We’ll pretty be keeping an eye on this new innovation as additional information becomes on the market.
