HP MJF4200: the professional 3D printing solution
We are pleased to announce that our printer family has grown. In addition to the familiar FDM and SLA printing technologies, we can now also offer MJF 3D printing from Hewlett Packard HP. The HP MJF4200 printer will be available from the beginning of May and is ready to bring your ideas to life in PA12 material.
The process
Multi Jet Fusion (MJF) is a new powder-based 3D printing process. It produces high-resolution, precise 3D objects with low porosity and high surface quality. Unlike selective laser sintering (SLS), MJF does not use laser radiation at all. Printing is carried out using an inkjet print head. Two different binder liquids on the surface of the powder bed bring the workpiece into the correct shape.
MJF uses infrared lamps as an energy source, which continuously expose the printing surface to light. The powder particles to be fused are moistened with a heat-conducting liquid (fusion agent) via the print head. The particles absorb the heat from the lamps and fuse with each other and with the layer below. To prevent the powder particles from fusing with each other beyond the intended area, a heat-inhibiting liquid (detailing agent) is applied around the contour of the component at the same time. This gives the 3D object a uniform and smooth surface.
Advantages and innovations you can expect:
• The HP MJF4200 is a plastic powder printer that impresses with its speed and consistent quality. Printing in powder eliminates the need for cumbersome support structures, resulting in better results and new possibilities. Infrared lamps generate the energy required for fusion.
• With a build volume of 380x284x380, large objects, prototypes, and small series can be printed quickly, cost-effectively, and with consistent quality.
• PA12 is a robust nylon material that is equally suitable for mechanically stressed and fine, filigree objects. The material also has high impact resistance and excellent chemical resistance to oils, fats, alcohol, gasoline, and cleaning agents.
• For post-processing and finishing, the material can be machined and refined by slide grinding and dyeing. For dyeing, the object is primed and painted, allowing any color mixture to be achieved. Alternatively, dyeing can be carried out in a bath, but this offers only limited color options.
