At present, spherical tantalum powder has achieved stable mass production, and the product has received unanimous praise from 3D printing enterprise users!

Sep 05, 2023

The Stardust Technology research team has conquered multiple key technologies for tantalum powder preparation and developed high-quality spherical tantalum powder for 3D printing using plasma spheroidization technology. The product has the characteristics of high purity and low oxygen, high sphericity, narrow particle size distribution, excellent flow performance, good batch stability, etc. It can fully meet the requirements of mainstream metal 3D printing technologies such as selective laser melting forming (SLM), electron beam selective melting forming (EBSM), etc. Using EOSM290 selective laser melting forming to print tantalum metal samples, the relative density is up to 99.8%, the tensile strength is greater than 650MPa, the yield strength is greater than 550MPa, and the elongation is greater than 25%. The comprehensive mechanical properties are excellent. The product has reached the target of foreign similar powder products, and the price can be reduced by 30% - 40%. It can replace imported similar powder, meet the urgent needs of domestic biomedical, aerospace, oil and gas exploration, nuclear industry and other fields, and has significant economic and social benefits.
