WE HAVE THE RIGHT PLASTIC POWDER MATERIALS FOR HSS

HIGH SPEED SINTERING


Evonik had already delivered the first powder material of the VESTOSINT® brand for the additive manufacturing market in 1996, thus setting standards that currently apply to 3D printing of plastic materials.


HSS FOR FLEXIBLE PRODUCTION OF FUNCTIONAL COMPONENTS

High speed sintering is a physical binder-jetting process that allows the tool-less production of functional prototypes as well as final consumer parts. The HSS process combines the advantages of two existing additive processes: selective laser sintering and binder jetting. While laser sintering, already allows many powder materials to be sintered into functional prototypes today, binder jetting impresses with its high printing rates in terms of size and speed of the construction site. High Speed Sintering thus allows the economical processing of larger plots and a wider selection of materials. 

In the HSS process, a thin layer of plastic granulate, such as PA 12 powders, is applied on to a heated building platform. An inkjet print head then moves over the entire surface of the platform and moistens the areas of the construction site with infrared light-absorbing ink, on which the prototype is to be produced. The building platform is then irradiated with infrared light. The wetted areas absorb the heat, which sinters the powder layer underneath. However, the unprinted powder remains loose. After sintering, the building platform is lowered by one layer thickness. This process is repeated until the assembly of a component is completed. The sintered parts are then cooled down in a controlled manner in the installation space before they can be removed and unpacked. In contrast to laser-based processes, the entire building platform can be printed in just one go, which enables a constant layertime time, irrespective of the size and complexity of the parts. Inert gas atmosphere is also not necessary for the HSS printing process. 

VOXELJET UNVEILS NEW 3D-PRINTING TECHNOLOGY

HSS printers from voxeljet offer unprecedented open sourcing possibilities. With the new ProPrint control software, users can program and insert customer-specific macros in just a few steps to adapt the printer to the desired material parameters and process operations. In addition, the software can also be used for individual process data mining, enabling the recording and evaluation of a wide variety of process data as required. Moreover, the user can process different powder materials, as the powder material does not necessarily have to be purchased from voxeljet. 

The HSS technology from voxeljet allows the interaction between material and machine to be optimized and thus the offering of the best possible material. The providing of an open machine with such a high degree of flexibility in terms of material possibillities and a rapidly adaptable process such as Binder Jetting is, definitely a unique selling point. In addition, The wide range of materials is trend-setting for this technology.
