Description

A kind of 3D printer wire rod fast-drying device
Technical field
The present invention relates to 3D printer fields, and in particular to 3D printer wire rod fast-drying device.
Background technique
3D printing technique comes across mid-term the 1990s, experienced development in more than 20 years, which has been employed In multiple fields such as space flight, building, medicine, electronics.Now with 3D printing with more and more extensive, more and more materials It is developed and applies to print, it is also higher and higher to the required precision of printout.Many commonly-used material such as PA, PLA etc. inhale Aqueous preferable material, due to exposure for a long time in air, can absorb makes the material printed generate bubble compared with juicy, Extreme influence is brought to the precision and mechanical property of printout.Therefore a kind of 3D printer wire rod fast-drying device, which becomes, needs It wants.
Summary of the invention
In order to realize the flash baking of 3D printer wire rod, the present invention provides a kind of 3D printer wire rod flash baking dresses It sets, good drying effect, it is small in size at low cost, it is compact-sized and simple.
Of the invention is achieved in that: a kind of 3D printer wire rod fast-drying device, including heating mechanism and drying machine Structure, the heating mechanism include: that resistance wire is uniformly and intimately wound on copper pipe, are filled between the gap of the resistance wire thermally conductive Silicone grease, accompanies temperature sensor between the resistance wire and copper pipe, the insulation adhesive plaster is coated on outside resistance wire, is consolidated by heat-shrink tube It is fixed;The drier includes: that hothouse is formed among drier main component and the mating connection of drier end cap, described dry Dry room is placed with water-absorbing sponge, and the hothouse is quick detachable, and water-absorbing sponge is replaceable, and the ferrule fitting connects drier master Body part and copper pipe, quick connector connect drier end cap and Teflon pipe, and the ferrule fitting and quick connector are concentric, institute Teflon pipe connection spray head is stated as discharge nozzle.The resistance wire and temperature sensor and the master control borads such as single-chip microcontroller or red rabbit connect It connects, realizes the adjusting of heating temperature.This drying unit can be placed independently and is also connected and installed on printer by connector.Copper Tube bottom end can be used as feeding inlet, can also connect Teflon pipe by installation cutting ferrule quick connector, be used as by the Teflon pipe Expects pipe is suitable for certain special 3D printer designs.
Compared with prior art the beneficial effects of the present invention are:
1. may be implemented under higher heating temperature, since the present invention is in such a way that resistance wire winds copper pipe shorter Drying functions are completed in heating time, can on one side dry, while print, the time is saved, because the present apparatus has structure simply skilful Wonderful, small in size, easy to operate, low manufacture cost, advantage easy to repair are not only suitable for technical grade 3D printer and are also suitble to desktop 3D printer.
2. the present invention carries out wire rod drying using water-absorbing sponge, drying effect has been not only acted as, moreover it is possible to " wipe to wire rod Silk ", keeps wire rod cleaner after herein, reduces the impurity in printout.
With reference to the accompanying drawings and detailed description, the present invention is described in further detail.

Specific embodiment
A kind of 3D printer wire rod fast-drying device, including heating mechanism and drier, the heating mechanism include: Resistance wire 2 is uniformly and intimately wound in 1 on copper pipe, and heat-conducting silicone grease, the resistance wire 2 are filled between the gap of the resistance wire 2 Temperature sensor 9 is accompanied between copper pipe 1, the insulation adhesive plaster 3 is coated on outside resistance wire 2, is fixed by heat-shrink tube 4;It is described dry Dry mechanism includes: drier main component 603 and drier end cap 601 is cooperatively connected it is intermediate form hothouse 602, it is described dry Dry room 602 is placed with water-absorbing sponge, and the hothouse 602 is quick detachable, and water-absorbing sponge is replaceable, and the connection of ferrule fitting 5 is dry Dry mechanism body part 603 and copper pipe 1, quick connector 7 connect drier end cap 601 and Teflon pipe 8, ferrule fitting 5 and fast Connection-peg 7 is concentric, and the Teflon pipe 8 connects spray head as discharge nozzle.The resistance wire 2 and temperature sensor 9 and monolithic The connection of the master control borads such as machine or red rabbit, realizes the adjusting of heating temperature.This drying unit, which can be placed independently, is also pacified by connector Loaded on 3D printer.1 bottom end of copper pipe can be used as feeding inlet, can also connect Teflon pipe by installation cutting ferrule quick connector, By the Teflon pipe as feeding pipe, it is suitable for certain special 3D printer designs.
When print job starts, wire rod is inserted into through spray head from copper pipe bottom, can be set at spray head or at copper pipe bottom Stepper motor feeding is set, when 3D printer works, wire rod can at the uniform velocity pass through drying unit, and specific print speed determines feeding Speed, and then the duration that wire rod is dried has been codetermined with the length of copper pipe, it can be by the way that different add be arranged for different materials Hot temperature reaches best drying effect.
So that it is sufficiently absorbed water by PA material bubble 24 hours in water by experiment, obtained after without drying and processing Printing effect is very poor, generates a large amount of bubbles, and printout cannot form;150 degree of heating temperature, copper pipe length 30cm of setting, spray head 0.2 mm of aperture is dried the PA material sufficiently to absorb water by the device, microscopically observation printout, is generated without bubble, So solves air bubble problem when printing.Similarly, for other materials, suitable temperature and print speed are set, can be solved Bubble is led to the problem of when certainly printing, reaches good drying effect.
