Recently, Puris's metallurgical and powder technology combined with ExOne's binder injection technology, printing out the world's largest commercially available complex titanium metal parts. The metal part is about 19 x 11 inches (48 X 48 x 28 cm), with a cross section thickness of 0.375 inches and weighs about 31 pounds.
Puris is a pioneer in the development of spherical titanium powder atomization technology, ExOne is the world's leading manufacturers of industrial grade 3D printers.
Adhesive injection technology
When the titanium powder is heated, it will change the properties, such as the reduction of the powder combustion and the increase of the oxide content. Companies exone binder spray technology can under room temperature condition printed parts, to avoid stress accumulation and chemical and microstructural changes of other metal 3D printing technology in common residual stress, these are the key to making the business components.
In addition, the technique is able to eliminate the accumulation of residual stresses, which significantly reduces the time required for manufacturing components. Machine time is expensive, so it also means that the cost of the reduction and production cycle reduction.
High performance alloy powder
Puris think metallurgy expert team is the true wealth of a nation, they have been busy for the high quality metal powder to develop innovative technologies and processes to be used in aerospace, automotive, medical care, petroleum and natural gas industries.
In addition to titanium powder, the large parts also used Inconel Inconel) powder, in addition to the largest and the most important significance lies in the parts are very dense, and the powder than the commonly used 3D printing powder more economic.
