As an improvement, being equipped with bucket torsion shaft and powder tilting table in rack two, it is equipped in powder cylinder blanking port
Material toggling roller guarantees going on smoothly for material toggling, feeding and stirring work.The overall dimensions for reducing three-dimensional printer are improved and are beaten
The size of stamp type, the desktop grade color three dimension suitable for minimized office place print.
As an improvement, powder cylinder assembly to be mounted on to the downside of cylinder molding device, make full use of in original three-dimensional printer
Idle space reduces the space of powder storage, conveying and recycling in three-dimensional printer, makes entire three-dimensional printer interior arrangement
It is more compact.
As an improvement, the ball screw inside cylinder molding device is not moved in Z-direction, ball screw own rotation is driven
Ball-screw is moved freely in Z-direction, so that moulding cylinder inner piston and thermal insulation board be driven to go up and down, is mounted on molding for powder cylinder
Steric requirements is created on the downside of cylinder.
As an improvement, the powder cylinder blanking port respective side in power spreading device is equipped with blanking channel, power spreading device completed
When powdering works, extra powder then returns to powder cylinder from blanking channel, convenient for the recycling of powder, improves the utilization of powder
Rate reduces the overall dimensions of three-dimensional printer also instead of the waste material cylinder of original three-dimensional printer two sides.
