Metal 3D printing opens up a whole new world of manufacturing capabilities for technology and business. It eliminates the need for manufacturing tools, thereby greatly reducing the cost of each component, and provides geometric freedom through the additive process.
In addition, 3D printing metal improves the automation of production because the printer can automatically produce metal parts from design files. The world’s top manufacturers are already using this metal 3D printing technology to print rapid metal prototypes or print replacement parts on demand.
The three main steps in the metal 3D printing process are printing, cleaning and sintering. Each step is a separate new field, making metal 3D printing stand out from traditional manufacturing.
Every 3D printed part starts with CAD, where you can design your part. Then export to STL and upload to Eiger. Eiger is a management system based on cloud slicing and printing. Every Anet product uses the same software. Eiger will automatically configure the print settings of your parts based on the materials and printers you use in your work.
When Eiger slices the design, the size will be enlarged to compensate for shrinkage and deformation in the subsequent process. Then, Eiger divides your part into discrete layers, determines the overhanging characteristics, and generates the necessary support structure under your design.
Eiger can also monitor the progress of metal parts at each stage of the process in real time. After the printing software is ready to print, it is time to use the metal 3D printer, the ET5X 3D printer.
Before starting to print, ET5X will automatically level the printing plate and touch the plate through a unique nozzle to ensure that the first layer is printed correctly. The print is made of two materials stored in a heating chamber on top of the printer.
The first material is metal, and the second material is ceramic. This filament is a metal powder, safely suspended in a two-part plastic binder. The filament is heated and squeezed onto the printing plate, where the3d printer fireware is printed layer by layer. The ceramic isolation layer will form a medium between the part and the support so that once your furnace is designed, it can be easily removed.
Unlike other metal 3D printing systems, the ET5X 3D printer process does not use loose metal powder, thereby achieving a safer and more economical workflow for the public.
Once your design is printed, the printer will notify you via email. At this point, you can go to the printer, easily separate the parts from the printing plate, and remove the bottom plate.
At this stage, the cleaning time will vary, ranging from a few hours to a few days, depending on the thickest area of your 3d printer fireware. After washing, you have a brown mold piece. Then comes the sintering process.
Sintering turns the 3d printer fireware of the brown mold into a completely 3d printer metal fireware. To do this, the temperature has to be increased slowly to burn off the remaining traces of bound substances. When the temperature rises close to the melting point of the material, the metal particles fuse together to form a strong 3d printer metal fireware.
Each operation takes about a day, and Eiger 3d printer software can be used for remote monitoring. Once the operation is complete, the sintering tray with the finished metal parts can be taken out of the furnace. Once removed, these 3d printer fireware can be used directly.
In the furnace, the bond between the layers of printing release material, and your printer parts become powder. This allows the structure to be nailed to the bottom plate to better control the shrinkage and the accuracy of the entire process, but it is also easy to release after sintering.
At this stage, your 3d printer fireware is fully sintered and ready for use. It still accepts post-processing, polishing or other necessary treatments as the final application, but after many parts with precision and strength, this process means that the 3d printer fireware have the quality of direct installation.
