1 . Layering module
This module consists of :
•
The roller
The roller can move in a straight line using the carriage :
•
Maximum position: 400 mm
•
Maximum speed: 400 mm/s
•
Accuracy: <1 mm
And rotate :
•
Maximum speed: 3.7 turn per second
•
Accuracy: <5°
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: 140 x 140 mm
•
Powder volume: 3.85 liters
•
Stroke: 198 mm
•
Maximum speed: 20 mm/s
•
Positioning accuracy: ± 5 µm
•
Sintering piston
The parts are manufactured on a sintering plate (positioned on a plate support), located on the sintering piston. Its
characteristics are:
•
Dimensions of the sintering plate : 140 x 140 mm
•
Useful stroke: 100 mm (with a sintering plate of 15 mm thick)
•
Maximum speed: 40 mm/s
•
Positioning accuracy: ±3 µm
2 . Collecting tank
It recovers all non-sintered powders and residues of sintering that have to be treated within
external recycling system.
