Multi Jet Fusion 5210 technology

HP 3D MJF 5210 technology has the following principle of operation :

1. The HP MJF 3D printing process begins with a thin layer of polymer powder particles ;
2. The deposited dust comes preheated and brought to a temperature of about 165 ° C ;
3. One roller scrolling on the Y axis distributes evenly the dust all over the countertop, going to create 80 µm layers (called layer );
4. On the axis X a trolley consisting of 3 print heads and two fusion modules with a single step releases the two agents ;
5. This process involves two different types of agents:
   – Melting agent ;
   – Detail agent ;
6. L’ fusing agent comes applied where the dust particles are meant to fuse together leaving the rest of the powder unaltered so as to create a support structure with the remaining non-melted powder which encapsulates the part;
7. Instead, the detail agent is applied to the edges of the part to modify the casting process and create fine details and smooth surfaces;
8. While the fusing and detailing agents are deposited from the heads, i two lamp modules bring the temperature of the section of the part with the newly deposited agents to one temperature between 182 ° C -186 ° C . The reaction that generates heat with agents and dust , allows you to form a complete layer at each passage of the carriage on the X axis
9. The process then comes repeated until it forms a fully functional part.
