Description
Technical field
The present invention relates to a kind of part of 3D printer, particularly to a kind of filament cassette for 3D printer.
Background technology
3D printer, is that one kind is based on mathematical model, using powdery metal or plastic or other material, by successively print
Mode constructs the equipment of three-dimensional body.One of which 3D printer is to supply moulding material to extruder head in the form of filament, becomes
Section bar material is heated to molten condition in electrically heated mode in extruder head, and extruder head will produce according to 3D printer main frame
Three-dimensional body is printed in the path of extruder head opposed substrate movement in the way of in layer.This moulding material is the shape with filament
Formula is wound in filament cassette, when every silk having printed a filament cassette, needs to change filament cassette, makes 3D printer continue to beat
Print.
The 3D printer of existing low cost is mainly the background skill of the patent documentation being CN1216726C using such as notification number
Filament cassette described in art, referring to Fig. 1, is wound with silk 02 on reel 01, this reel 01 is attached to the silk of 3D printer
In the rotating shaft 011 of magazine installing rack, thus can achieve the printhead 03 that silk 02 is supplied to 3D printer.Using process
In, silk 02 is pulled out from reel 01, makes the filament being straightened by the conduit 04 being made up of the less material of frictional resistance,
Until filament is supplied to a pair of the feed roller 0321 and 0322 driven on printhead 03 by motor 033, in feed roller
Under 0321 and 0322 driving, silk 02 enters extrusion head 031, in extrusion head 031, the silk quilt of heated one-tenth molten condition
Extrusion is simultaneously removably deposited in substrate；The controller of this 3D printer passes through to control printhead 031 in the X-Y plane of level
Interior motion, controls substrate to move in vertical Z-direction simultaneously, thus in layer print three-dimensional body；Additionally, this 3D printing
The controller of machine also control the speed that feed roller 0321 and 0322 supplies silk to extrusion head 03.In order to cost-effective, low
The controller of the 3D printer of cost cannot calculate silk surplus in filament cassette, so cannot when there is no silk in filament cassette
User is reminded to change filament cassette；In computer aided design system during the model of design three-dimensional body, can go out according to a preliminary estimate
Corresponding silk usage amount, but the silk surplus due to being unable to estimate out in filament cassette, so cannot judge remaining in filament cassette
Silk whether enough, may result in the not enough needs of silk in print procedure carry out changing filament cassette and affect print progress with
Print quality；Because the silk 02 in reel 01 is in relaxed state, it is unfavorable for feed roller 0321 and 0322 to extrusion head
031 control supplying silk speed and dynamics；Due to this uncanned protection of reel 01, for ABS thermoplastic etc. to moisture-sensitive
Section bar material, the silk easily contact with moisture with the air, easily become tide, impact print quality.
For the sealing problem of above-mentioned filament cassette, disclose a kind of silk in the patent documentation for CN1216726C for the notification number
Magazine, including one be used for accommodating the reel being wound with silk air-tight chamber is dried, the silk drawn by chamber exports, and silk is entered
To device and prevent air enter within the chamber retention device.Air-tight chamber and retention device are dried by setting, can be effective
Prevent in filament cassette silk to become damp problem.
