Description
Technical field
The present invention relates to a kind of parts of 3D printer, particularly a kind of filament cassette for 3D printer.
Background technology
3D printer, is a kind of based on mathematical model, utilizes powdery metal or plastic or other material, constructs the equipment of three-dimensional body by the mode of successively printing.Wherein a kind of 3D printer is to supply with moulding material with the form of filament to extruder head, moulding material is heated to molten condition in electrically heated mode in extruder head, and three-dimensional body is printed in mode in layer in extruder head moves the extruder head producing according to 3D printer host path relative to substrate.This moulding material is to be wound in filament cassette with the form of filament, in the time that the silk of the complete filament cassette of every printing is expected, need to change filament cassette, makes 3D printer continue to print.
The existing printer of 3D is cheaply mainly to adopt the filament cassette of describing as in the background technology of the notification number patent documentation that is CN1216726C, referring to Fig. 1, on reel 01, be wound with silk material 02, this reel 01 is mounted in the rotating shaft 011 of filament cassette installing rack of 3D printer, thereby can realizes the printhead 03 that silk material 02 is offered to 3D printer.In use, silk material 02 is pulled out from reel 01, make the filament being straightened by the conduit 04 of being made by the less material of frictional resistance, until filament is supplied to a pair of feed roller 0321 and 0322 being driven by motor 033 on printhead 03, under the driving of feed roller 0321 and 0322, silk material 02 enters extrusion head 031, in extrusion head 031, is extruded and is removably deposited in substrate through the silk material that is heated into molten condition; The controller of this 3D printer moves in the X-Y plane of level by controlling printhead 031, controls substrate in the motion of vertical Z-direction simultaneously, thus in layer print three-dimensional body; In addition, the controller of this 3D printer is also being controlled feed roller 0321 and 0322 and is being supplied with to extrusion head 03 speed that silk is expected.For cost-saving, the controller of 3D printer cannot calculate in filament cassette silk material surplus cheaply, so cannot reminding user to replace filament cassette in the time not having silk to expect in filament cassette; Design the model of three-dimensional body in computer aided design system time, can go out according to a preliminary estimate corresponding silk material use amount, but due to the silk material surplus of being unable to estimate out in filament cassette, so cannot judge in filament cassette, whether remaining silk material is enough, may cause the not enough needs of silk material in print procedure to change filament cassette and affect print progress and print quality; Because the silk material 02 in reel 01 is in relaxed state, be unfavorable for the control of feed roller 0321 and 0322 subtend extrusion head 031 for silk speed and dynamics; Due to the uncanned protection of this reel 01, for ABS thermoplastic etc. to moisture-sensitive shaped material, silk material easily with airborne contact with moisture, easily become tide, affect print quality.
For the sealing problem of above-mentioned filament cassette, the patent documentation that is CN1216726C at notification number has been announced a kind of filament cassette, comprise that one for holding the dry air-tight chamber of the reel that is wound with silk material, the silk material outlet of being drawn by chamber, silk material feed arrangement and prevent that air from entering the retention device in chamber.By dry air-tight chamber and retention device are set, can effectively prevent that in filament cassette, silk material becomes damp problem.
