The embodiment of the invention provides a 3D printing consumable recycling method which is suitable for a powder spreading type 3D printer.
Referring to fig. 1, the method includes the following steps:
s1: applying a first magnetic field to a target slice layer, wherein the target slice layer is covered with the remaining first color printing consumables that are not bonded;
s2: applying a first acting force to the remaining first color printing consumables, so that the remaining first color printing consumables move along the horizontal direction and are subjected to a Lorentz force opposite to the gravity;
s3: and when the gravity and the Lorentz force received by the remaining first color printing consumables are consistent, applying a second acting force to the remaining first color printing consumables to enable the remaining first color printing consumables to operate in a preset direction until being recovered.
Specifically, a magnetic field is applied to the printing device, and the magnetic field covers the currently printed target slice layer. The applied magnetic field can enable the charged residual first color printing consumables to be subjected to Lorentz force when moving in the magnetic field along the horizontal direction under the action of the first acting force, and the direction of the applied magnetic field is controlled, so that the Lorentz force applied when the residual first color printing consumables move along the horizontal direction is opposite to the gravity direction; and controlling the magnetic induction quantity of the magnetic field to ensure that the Lorentz force on the first color printing consumable material is equal to the gravity. And then applying a second acting force to the rest of the first color printing consumables to enable the rest of the first color printing consumables to run along a preset direction until the rest of the first color printing consumables are recovered.
In one embodiment, the first force is generated by applying a gas flow. Because the powder spreading printing is carried out by using more printing consumables than the actual consumption amount, the residual printing consumables which are not bonded are certainly blown in the air by the air flow, and the direction of the applied air flow is controlled to control the movement direction of the printing consumables to be vertical to the direction of the magnetic field on the horizontal plane, so that the charged printing consumables are subjected to the Lorentz force opposite to the direction of gravity in the magnetic field.
When the gravity that receives and the lorentz power size unanimous with gravity reversal when remaining printing consumables, printing consumables in aerial a certain position atress balance, suspend in the air, adjust recovery unit's height this moment, make its and printing consumables atress balanced position's highly uniform, exert the second air current to printing consumables, blow in recovery unit with the printing consumables of suspension. Preferably, the direction of the second air flow coincides with the direction of the first air flow.
In one embodiment, the second air flow is the same as the first air flow, and the printing consumables are suspended in the air and horizontally move into the recycling device along the direction of the first air flow under the driving of the first air flow.
In one embodiment, the second air flow and the first air flow are generated by the same pneumatic control device, wherein the first air flow is low in intensity, the movement speed of the printing consumables which are blown up by the first air flow and move in the horizontal direction is low, and when the stress balance is achieved, the second air flow with high intensity is applied to blow the printing consumables into the recovery device quickly.
In one embodiment, the second air flow and the first air flow are generated by different air control devices, wherein the first air flow is low in intensity, the movement speed of the printing consumables which are blown up by the first air flow and move in the horizontal direction is low, and when the stress balance is achieved, the second air flow with high intensity is applied to blow the printing consumables into the recovery device quickly.
Above-mentioned embodiment makes electrified surplus printing consumables keep the stress balance state on a certain height under lorentz force and action of gravity through applying magnetic field and first effort, then makes surplus printing consumables move to recovery unit along predetermineeing the direction through applying the second effort, the effectual recovery that realizes the printing consumables is favorable to the cyclic utilization of printing consumables, avoids extravagant.
Example two
Often can use the printing consumables of multiple different colours when 3D prints in order to make printing consumables ability cyclic utilization, need retrieve printing consumables classification. It is considered that in the magnetic field, if the amount of charge of the printing consumable tape is different, the magnitude of the lorentz force received is also different. Utilize this characteristic, exert the electric charge of different electric quantities to the printing consumables of different colours, realize the separation of different colours printing consumables under the inconsistent condition of size that receives lorentz power to realize the categorised recovery of different colours printing consumables.
According to the formula F ═ B × q × v (where F is lorentz force, B is magnetic induction intensity, q is moving object charge amount, and v is moving speed of the moving object), it can be seen that, in the magnetic field with the magnetic induction intensity of B, when the moving speeds of the printing consumables are the same, the printing consumables with larger charge amount are subjected to larger lorentz force. Take the printing consumables of different electric quantities because receive the lorentz power of equidimension not, can be in aerial layering, thereby for example the printing consumables that the electric quantity is little reach the force balance at a certain position at first and suspend in the sky, and the printing consumables that the electric quantity is big then can continue to rise, with the printing consumables layering that the electric quantity is little, exert the second effort to the printing consumables that the electric quantity is little this moment, make it operate until being retrieved along predetermineeing the direction.
Consequently can change the magnetic induction intensity in magnetic field according to the electrified volume of the printing consumables of different colours, let the printing consumables of different colours reach force balance (gravity and lorentz power) in the different high position one by one, then retrieve the printing consumables of different colours one by one.
The magnitude of the magnetic induction can be calculated by the following formula:
F＝B×q×v，
wherein F is Lorentz force, B is magnetic induction intensity, q is moving object electrification amount, and v is moving speed of the moving object.
G＝m×g，
Wherein G is gravity, m is the mass of the moving object, and G is the acceleration of gravity.
When F is G, B × q × v is m × G;
therefore, B is (m × g)/(q × v).
M, g and q of the printing supplies are determined values, and the value of v can be calculated according to the first airflow intensity, so that the value of B can be determined.
In one embodiment, the different color printing consumables include at least first and second color printing consumables. Before printing, applying charges with different electric quantities to a first color printing consumable material and a second color printing consumable material (the electric quantities are kept unchanged in the printing process), and after printing of a layer of slices is finished, applying a first magnetic field and a first acting force to the printing device, wherein the first magnetic field enables the first printing consumable material to reach stress balance at a first position, and applying a second acting force to recover the first color printing consumable material; and then, applying a second magnetic field and a third acting force to the printing device, wherein the second magnetic field enables the second color printing consumables to reach stress balance at a second position, and applying a fourth acting force to recover the second color printing consumables. In this embodiment, the first force, the second force, the third force, and the fourth force are all generated by applying an air flow. Referring to fig. 2, the specific steps are as follows:
s11: applying a first magnetic field to the printing device;
and controlling the magnetic field device to generate a first magnetic field, and applying the first magnetic field to the printing device, wherein the magnetic induction intensity of the first magnetic field can ensure that the first color printing consumables are stressed in a balanced manner when in the first position.
S12: applying a first air flow to the printing device, wherein the first air flow blows printing consumables of different colors into the air and moves in the horizontal direction in the first magnetic field;
the first air current of appllying blows the printing consumptive material of all different colours aloft and along the horizontal direction motion, because the electric quantity of first colour printing consumptive material and second colour printing consumptive material is inconsistent, and the lorentz power that receives is inconsistent, and two kinds of printing consumptive materials can divide from top to bottom gradually.
S13: when the gravity borne by the first color printing consumables and the Lorentz force opposite to the gravity are consistent in magnitude, applying second air flow to the first color printing consumables, wherein the second air flow blows the first printing consumables into a recovery device;
when the gravity that first colour printing consumables received and the lorentz power size that is the reverse with gravity are unanimous, first colour printing consumables are in first position atress equilibrium, adjust recovery unit's height, make it unanimous with the height of first position, then to first colour printing consumables applys the second air current, will first colour printing consumables blows into in recovery unit.
S14: applying a second magnetic field to the printing device;
the magnetic field that will print the device changes magnetic field by first magnetic field into second magnetic field with the back is retrieved to first colour printing consumptive material, changes magnetic induction, and the magnetic induction in second magnetic field can make second colour printing consumptive material atress balanced when the second position.
S15: applying a third air flow to the printing device, wherein the third air flow blows printing consumables of different colors into the air and moves in the horizontal direction in the first magnetic field;
s16: when the gravity borne by the second color printing consumables and the Lorentz force opposite to the gravity are consistent, applying fourth air flow to the second color printing consumables, wherein the fourth air flow blows the second color printing consumables into a recovery device;
when the gravity that the second colour printing consumables received and the lorentz power size that is the reverse with gravity were unanimous, the second colour printing consumables is in second position atress balance, adjusts recovery unit's height, makes its highly uniform with the second position, then it is right the fourth air current is applyed to the second colour printing consumables, will the second colour printing consumables blows in recovery unit to accomplish the categorised recovery of first colour printing material and second colour printing material, be favorable to printing material's cyclic utilization.
And after each layer of slice printing is finished, applying a magnetic field and air flow to the printing device, and after printing consumables are recovered, stopping applying the magnetic field and the air flow to print the next layer of slice until the whole printing process is finished.
Illustratively, the printing consumables include a white printing consumable W and a black printing consumable K, the charge applied to the white printing consumable is + e, the charge applied to the black printing consumable is +2e, and the white printing consumable W and the black printing consumable K are respectively solved according to the formula B ═ m × g)/(q × v) and are BwAnd BK。
Firstly, applying magnetic induction B to a printing devicewAnd applying a first air flow, under the action of which the white printing consumable W is set in position HwThe stress balance is achieved; because black printing consumables K electrified volume is the twice of white printing consumables W, under the condition that quality and speed are the same, the lorentz force that receives is the twice of white printing consumables W, consequently black printing consumables K still rises under the lorentz force effect when white printing consumables W reaches force balance, wait until after white printing consumables W and black printing consumables K have obviously separated, adjust recovery unit to with H printing consumables KwAt the same height, a second air flow is applied to blow the white printing consumables W into the recycling device; and then closing the air control device and the magnetic field device, and waiting for the rest printing consumables to fall back to the printing device.
Then, the magnetic induction of the magnetic field is converted into BK，Applying a third air flow to the printing device, and setting the black printing consumable K at the position H under the action of the third air flowKThe stress balance is achieved; adjusting the recovery device to HKAt the same height, a fourth air flow is applied to blow the black printing consumable K into the recycling device. Thereby completing the recovery of the printing consumables with two different colors.
In another embodiment, the printing supplies comprise more than two different colors, different electric charge quantities can be applied to the printing supplies of different colors, and the printing supplies of different colors are recovered one by one according to the magnitude sequence of the electric charge quantities of the printing supplies of different colors during recovery. For example, the printing consumable with the minimum charge is recycled first, and the printing consumable with the maximum charge is recycled last; or the printing consumable material with the largest charge amount can be recycled firstly, and the printing consumable material with the smallest charge amount can be recycled finally. Preferably, the printing consumables with the largest charged amount can be recovered first, so that the printing consumables with the larger charged amount are subjected to the larger upward lorentz force, the higher the upward movement speed is, the easier the printing consumables are separated, and the printing consumables can be recovered first.
