Application of 3D Printing Technology on Metal Parts
Australian alumina ban disrupts Rusal production -- Australia's ban on exports of alumina and aluminium ore to Russia, including bauxite, will further disrupt supply chains and production at leading aluminium producer Rusal, consultancy Wood Mackenzie said on Monday.
The Australian government announced the ban on Sunday as part of its ongoing sanctions against Moscow for its aggression in Ukraine, saying Russia relies on it to meet one-fifth of its alumina needs. WoodMac senior manager Uday Patel said in a statement that the ban would make it difficult for Rusal to maintain normal primary aluminum production.
Rusal said it was assessing the impact of Australia's move and would make further announcements if necessary. "It is increasingly likely that UC Rusal's only option for alumina procurement will be through a Chinese entity." The Australian alumina ban has also had an impact on the 3D Printing Technology prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.
As a new type of manufacturing technology, 3D printing has shown very broad
application prospects, and has shown a strong development momentum in more
fields such as equipment design and manufacturing, equipment support, and
aerospace. This is because 3D printing technology has the following
1. High precision: At present, the precision of 3D printing equipment can
basically be controlled below 0.3mm.
2. Short cycle time: 3D printing does not require a mold making process,
which greatly shortens the production time of the model. Generally, a model can
be printed in a few hours or even tens of minutes.
3. Personalization is possible: 3D printing has no limit to the number of
models that can be printed, no matter one or more models can be produced at the
4. Diversity of materials: A 3D printing system can often achieve printing of
different materials, and the diversity of such materials can meet the needs of
5. Relatively low cost: Although 3D printing systems and 3D printing
materials are relatively expensive now, if they are used to make personalized
products, the production cost is relatively low.
3D printing technology of metal parts, as a more cutting-edge and more
potential technology in the whole 3D printing system, is an important
development direction of advanced manufacturing technology. At the same time,
with the development of science and technology and the needs of popularization
and application, the use of rapid prototyping to directly manufacture metal
functional parts has become the main development direction of rapid
