Method for Increasing the Green Strength of 3D-Printed Metal Components by Modification of Metal Powder

- Abstract
- 3D printing of metal components is a growing industry where the demand of highly precise and complicated geometrical metal structures are met. Höganäs is with its Digital Metal department one of the few companies that do 3D-printing by powder bed ink-jet technique. In this technique a binding material is needed in order to retain the designated structure until sintering.
In this project a 316 L gas atomized stainless steel metal powder was modified in its surface structure by using two materials, (a binder and a surface modifying material “Surfmod”), and used to make TRS-bars and print components. It was shown that it is possible to increase the binder and Surfmod contents of TRS-bars and printed components. By testing the green...

By testing the green strength, (GS), it was proven that in a lab environment it is possible to create TRS-bars with the help of modified powders that have a higher GS than the TRS-bars made from non-modified powders. In order to achieve a higher GS for printed parts further testing is needed. (Less) - Popular Abstract
- In this report an investigation has been conducted on the possibility to make the printing process of 3D metal objects in a more effective manner. Today the ink-jet powder bed 3D printing of metal components, demands elaborate post-processing operations that could go quicker if the printed objects were to be more robust. In lab-scale it has been proven that printing stronger parts than as of today is possible, but has yet to be proven in a printing operation.
