1 . Layering module
This module consists of :
•
The roller
The roller can move in a straight line using the carriage :
•
Maximum position: 355 mm
•
Maximum speed: 200 mm/s
•
Accuracy: <1 mm
And rotate :
•
Maximum speed: 5 turn per second
The combination of different movements of roller and carriage are adjustable for carrying out actions of layering such as
spreading, smoothing and compacting . The layer thickness of powder differs depending on the material properties (particle
size, flowability...) and on the desired part characteristics.
•
The scraper
Its geometry enables to carry the powder from the feeding piston to the sintering piston .
•
Feeding piston
This piston contains the volume of powder that will be used for sintering . Its characteristics are given below:
•
Dimensions: 100 x 100 mm
•
Powder volume: 2 liters
•
Stroke: 200 mm
•
Maximum speed: 20 mm/s
•
Positioning accuracy: ± 5 µm
•
Sintering piston
The parts are manufactured on a sintering plate, located on the sintering piston . Its characteristics are:
•
Dimensions of the sintering plate : 100 x 100 mm
•
Useful stroke: 80 mm (with a sintering plate of 10 mm thick)
•
Maximum speed: 20 mm/s
•
Positioning accuracy: ±3 µm
•
Tamping unit
The compacting element translates in order to clog the feeding piston, then, the piston rises to compact the powder .
2 . Collecting tank
It recovers all non-sintered powders and residues of sintering that have to be treated within
external recycling system .
