Inks with different colors can be combined to produce a very large array of colors, in a similar way to a 2D inkjet printer. However, parts are printed without heat so there is no differential cooling and therefore no warping. Despite the advantages of binder jetting, there are also some challenges associated with the process. This inkjet is guided by a 3D model to selectively apply a binder to a thin bed of powder in the shape of a part layer. What are the disadvantages in utilizing traditional manufacturing enterprise? TheMetal Binder Jettingis a process comprising several manufacturing steps and requiring several associated equipment (printing machine, mixer, powdering machine / sieving, ovens, sintering furnace, post-processing equipment). These can even be combined with each other, so that, for example, models made of stainless steel and plastic are conceivable. Then, a carriage with inkjet nozzles (which are similar to the nozzles used in desktop 2D printers) passes over the bed, selectively depositing droplets of a binding agent (glue) that bond the powder particles together. Due to the lack of heating, parts have very good dimensional accuracy. The selection criterion used was the number of articles found in the literature review dealing with the AM technology evidenced and also because they are the same additive technologies referenced as the most popular in the industry (3D Hubs, 2016 3D Hubs. Second, no support structures are required for the metal binder jetting process, since printed parts are surrounded by loose, unused powder. Ultimately, powder bed fusion uses lasers or electron beams to melt and fuse different powder materials. It is almost impossible to predict which dimensions will be most affected, and the shrinking is not equal all over the part. This cookie is set by GDPR Cookie Consent plugin.
