VoxeljetAG, a high-speed, large-size 3D printer and on-demand component service provider, announced the first high-speed sintering (HSS) process 3D printing system.Previously, voxeljet's 3D printers were mainly used for mold and pattern making applications.Now, with the latest HSS technology, voxeljet will be able to produce end products directly, further entering the thermoplastic market.
HSS is based on the same technology as voxeljet's core technology, binder injection.The new process involves depositing small layers of polymer powder, such as PA12 or TPU, and then selectively depositing infrared absorption fluids on the surface of the powder that needs to be sintered by the inkjet printer head.No liquid is used in the printing process, which minimizes the cost of consumption.The building area is then exposed to infrared light, and the liquid absorbs energy, melting and sintering the powder underneath.The process is repeated layer by layer to create functional plastic parts.
According to the introduction, the new HSS process can print parts with similar properties and quality with selective laser sintering, multi-jet fusion or injection molding.Users can produce multifunctional and fully functional prototypes such as supports, enclosures, and other functional components.Combined with excellent surface quality, sharp and clear edge, and the details of the actual resolution, using HSS technology printing can be directly used in automobile parts, industrial equipment and the function of the application of consumer goods.
Voxeljet's chief executive says the new high speed sintering process provides customers with great flexibility through technology and parameters that they can tailor to their specific needs.In addition, materials and new module printing software will provide more customized options for customers.Voxeljet's industrial printers are capable of achieving high quality print resolution, which is consistent in whatever level of printing.Because of the wide print width of the print head, the printing rate on large platforms is likely to increase significantly in the future.Compared with other additive manufacturing processes, this process is more efficient.
