GENERAL MACHINE OPERATION

The manufacturing process takes place as follows:
• 

Processing of the CAD file with 

ProX DMP Manufacturing

, standalone software, in order to slice the part as a series of 

superimposed cross-sections. Creation of the manufacturing file (*.FAB2, or *.FAB3 files), used by the ProX

®

 DMP metal 

printers . 

• 

Preparation of the machine, loading of the sintering plate and purging the chamber .

• 

Uploading the *.FAB2 or *.FAB3 file onto the machine.

• 

Dispensing a powder layer on the sintering plate (Layering cycle) .

• 

Fusing the metal powder into a solid part using a focused laser beam (Sintering cycle) .

• 

Repeated execution of layering and sintering cycles until the part is produced .

• 

Unloading the part and possible post-processing and finishing in order to obtain the desired characteristics.

INTENDED USE

Laser sintering operations are performed on metal powders only .
Each metal powder should only be used after checking the information provided by the supplier, the material safety data 

sheet (MSDS) and any applicable regulations .

Limitations relating to the manufacture of 3D objects by laser sintering

Before manufacturing a 3D object, please ensure that none of the following criteria are met :

• 

A 3D object with at least one of the layers covering more than half of the total surface of the sintering plate,

• 

3D object with an undercut angle< 45 ° compared to the horizontal surface of the sintering plate,

• 

3D object where its minimum thickness is 5 times smaller than its height,

Without being exhaustive, these criteria represent the majority of cases to be checked before manufacturing a 3D object by 

laser sintering .

Conditions relating to the Layering

During the manufacturing process, the roller must not disturb any of the previous sintered layers . This is why the correct 

conditions required for the manufacturing of layers is given in the following diagram .
