High Strength Nylon

Selective Laser Sintering

SLS produces strong models. It uses Polymide which is a Nylon material. The maximum build size for SLS printing is 320 x 320 x 600mm. We only run our SLS machine twice a week as it requires a full build in order to operate cost-effectively as a consequence the lead time on SLS is longer than the other printing technolgies we use.

Technology

Selective laser sintering is used to build your design with this material. The models are printed layer by layer by a laser that draws thin lines in the powder, which melts and bonds it together in order to form a thin layer of the model. After a layer is printed, a new layer of fresh powder is spread over the surface by a roller. The printer has a print chamber that is heated to just below the melting point of the powder; the laser beam adds the extra energy to melt the powder, forming a solid model. After a print job is finished, the result is a big block of heated powder with the printed models contained inside.

    

Multi Jet Fusion (MJF)

Multi Jet Fusion or MJF is an additive manufacturing method invented and developed by the company Hewlett-Packard (HP). It creates parts additively thanks to a multi-agent printing process.

In this process a fusing agent is applied on a material layer where the particles are destined to fuse together. Then a detailing agent is applied to modifiy fusing and create fine detail and smooth surfaces. To finish, the area is exposed to energy that will lead reactions between the agents and the material to create the part. 

When the printing process is complete, the build box is removed from the printer. An operator carefully extracts the parts from the build box and removes the remaining powder thanks to brushes and air blowers.

Multi Jet Fusion 3D Printers

At 3D Printing Studios we are using the HP Multi Jet Fusion 3D 4200 printer to 3D print your part in Multi Jet Fusion PA 12.  The machine has a maximum building size of 380 X 284 X 380 mm for raw printing. Layer thinkness between is between 0.07mm to 0.12mm. Accuracy is +/- 0.2mm.
