Printing of parts using Multi Jet Fusion technology
This innovative additive manufacturing technology allows the manufacture of prototypes or functional parts in a fast and cost-effective way, allowing to have very agile 3D printing services.
Multi Jet Fusion printing consists of depositing a layer of powdered material on which injection heads will “draw” the geometry to be manufactured, using a product or melting agent instead of ink. Then, a light source will accelerate the fusion or polymerization process.
Multi Jet Fusion 3D printing technology does not use lasers to fuse the material. The part is “printed” layer after layer without waiting for the previous layer to fuse. By fusing together and not layer by layer, we get totally integral, solid, functional and strong parts.
This saves both time and energy consumption. Once the piece is finished, the vacuum is made, eliminating the remains of material notmelted, leaving very reduced post-processing tasks.
Advantages of 3D Multi Jet Fusion printing
The advantages of Multi Jet Fusion technology can be summarized in one sentence: Functional parts in record time.
Other notable aspects of this type of printing are:
Printing on rigid and flexible plastic materials
For example PA12 (nylon) or TPU (thermoplastic polyurethane)
High Isotropy
That is, the material properties remain constant, regardless of the geometry of the design to be printed.
Low porosity
Thanks to the reduced granulometry, it is possible to obtain parts with very low porosity
Reduced delivery times
The Multi Jet Fusion technology, by requiring little post-production, allows much faster deliveries than other 3D printing techniques.
Multiple and articulated parts
The high resolution offers the possibility of creating several parts at the same time, being able to generate articulations between them, such as hinges, slides, etc.
High resolution 3D printing
Just as when we have a design on screen we speak of a pixel as the element that will determine its resolution, in Multi Jet Fusion printing, we speak of “voxel” as the factor that measures the resolution or degree of finishing of the piece.
In fact, as we mentioned before, the piece is printed by ink-jet heads (hence the multi jet) with a horizontal resolution similar to that of an inkjet printer.
The third dimension or height of the voxel, is provided by the thickness of the base material, which would be equivalent to the paper in our simile. The layers of this material can be around 80 microns. A record that will give your pieces a very high precision.
Parts manufactured with different finishes and properties.
Multi Jet Fusion 3D printing allows for different properties in certain
zones thanks to the application of different chemical agents.
Besides the agent that generates the fusion of the particles, others allow to modify the roughness, the elasticity or even the degree of transparency
Materials
There are two materials available for printing parts by Multi Jet Fusion. Both are plastics widely used in various industries, with very interesting properties, while allowing their alteration through the application of the agents mentioned above.
TPU Thermoplastic Polyurethane
Polyamide PA12
