In the present embodiment, the described active force that described contactless bracing or strutting arrangement provides described at least one parts does not produce with contacting of described at least one parts based on described contactless bracing or strutting arrangement.Alternatively, described contactless bracing or strutting arrangement does not contact with described at least one parts, and further alternatively, described contactless bracing or strutting arrangement does not contact with other parts of described object.For instance, the described active force that described contactless bracing or strutting arrangement provides can be, the impulse force of gas or suction, the electric field force of electric field to electrical body, the active force of ultrasonic wave or light wave etc.

The present embodiment passes through according to the printer model file of an object, determine at least one parts in described object in the print procedure of described object required support force apply position and size, and control a contactless bracing or strutting arrangement to described at least one parts, provide the active force that meets described required support force in described print procedure, the scheme that provides a kind of auxiliary 3D to print, particularly, utilize contactless support force to replace at least in part the supporting construction of printing to support parts, time-write interval and printed material have been saved, and avoided the impact of excision supporting construction on object outward appearance.

The method of the present embodiment is described further below by some optional implementations.

In the present embodiment, alternatively, described printer model file includes but not limited to: the shape of described object, material, page order.That is to say, in the printer model file of an object, at least described shape, material and the page order of described object.Particularly, the shape of described object comprises: form the shape of various piece of described object and the structural relation between various piece; The material of described object comprises: the material that forms the various piece of described object; The page order of described object comprises: form the page order of the various piece of described object, first print rear which part of which part.

In the present embodiment, between the each several part due to adjacency in an object, there is stress, correspondingly, can described object be divided into a plurality of parts (Parts) according to mutual stress.Because the stress between the each several part of adjacency in an object may change along with print procedure, alternatively, the division of described middle parts of objects part also may be along with print procedure changes.

Wherein, some parts may need to support in print procedure, and some parts may not need to support in print procedure.Alternatively, the present embodiment described according to the printer model file of an object, at least determine parts in described object in the print procedure of described object required support force apply position and size before, also comprise:

According to described printer model file, determine described at least one parts that need support in described object in described print procedure.

For instance, for each parts, can determine according to the shape of these parts, material the center of gravity of these parts, further, at least according to the center of gravity of these parts, with each parts of this members abut and the structural relation of these parts, and these parts and with the page order of each parts of this members abut, can determine whether these parts need to support.

In the present embodiment, between each parts due to adjacency in an object, have stress, and the page order of each parts has successively, therefore, in the print procedure of described object, whether each parts need support force and required support force all can change.Alternatively, need at least one parts of support to change with described print procedure.Correspondingly, if described at least one parts change with described print procedure, and the required support force of described at least one parts of determining in 110 changes with described print procedure, control described contactless bracing or strutting arrangement in 120 and provide the satisfied active force that changes required support force with described print procedure to described at least one parts that change with described print procedure.

Alternatively, described at least one parts in described print procedure required support force apply position and/or size changes with described print procedure.For instance, the position that applies of described required support force changes with described print procedure, or the size of described required support force changes with described print procedure, or apply position and the size of described required support force all change with described print procedure.

Fig. 2 A, 2B are respectively in the application in print procedure not a kind of schematic diagram of the required support force of parts in the same time.It should be noted that, in Fig. 2 A, 2B, only with vertical two dimensional surface, illustrate, and do not mean that the restriction to the application.The part object that in the print procedure of described object a moment (with t1 represent) print of Fig. 2 A for determining according to the printer model file of an object, the part object that in described print procedure another moment (with t2 represent) print of Fig. 2 B for determining according to described printer model file, t2>t1, the part object constantly having printed at t1, t2 includes parts 1 and parts 2.

As shown in Figure 2 A, at t1 constantly, 2 pairs of parts 1 of parts produce stress N1 at adjoiner, N1 is no more than the maximum stress of the 2 pairs of parts 1 of parts that determined by structure, material etc., and the gravity of parts 1 is G1, and the distance of the adjoiner of the center of parts 1 and parts 1 and parts 2 is L1, the moment that is the gravity of parts 1 is G1*L1, therefore,, in order to guarantee equalising torque, the t1 constantly moment of the required support force T1 of parts 1 should equate with the moment G1*L1 of the gravity G1 of parts 1; In addition, take vertical two dimensional surface as example, suppose that the component of stress N1 on x axle is component on y axle is the t1 constantly component of the required support force of parts 1 on x axle is component on y axle is further contemplate the t1 pressure P 1 of printing head to the parts 1 of printing constantly, suppose P1 vertically downward,, in order to guarantee the stress balance of parts 1, N1, G1, T1, P1 need meet: constraints based on above-mentioned equalising torque and stress balance, can determining means 1 applies position, direction and size at the constantly required support force T1 of t1; Further, constraints based on above-mentioned equalising torque and stress balance, a plurality of support force T1 may can be determined, a plurality of support force T1 that apply position, direction and/or vary in size, correspondingly, can therefrom select a support force T1, alternatively, select a support force T1 who makes stress N1 minimum.Need to illustrate, in some possible scenes: P1 is 0, such as after parts 1 have been printed; And/or N1 is 0, such as parts 1 without other parts of adjacency, other parts of parts 1 adjacency while all also not starting to print; And/or parts 1 directly contact with print platform, except above-mentioned various power, parts 1 may also be subject to the support force of print platform.In addition, if without the direction of considering support force T1, constraints that can be based on above-mentioned equalising torque, can determining means 1 applies position and size at the constantly required support force T1 of t1.

As shown in Figure 2 B, at t2 constantly, 2 pairs of parts 1 of parts produce stress N2 at adjoiner, N2 is no more than the maximum stress of the 2 pairs of parts 1 of parts that determined by structure, material etc., and the gravity of parts 1 is G2, and the distance of the adjoiner of the center of parts 1 and parts 1 and parts 2 is L2, the moment that is the gravity of parts 1 is G2*L2, therefore,, in order to guarantee equalising torque, the t2 constantly moment of the required support force T2 of parts 1 should equate with the moment G2*L2 of the gravity G2 of parts 1; In addition, take vertical two dimensional surface as example, suppose that the component of stress N2 on x axle is component on y axle is the t2 constantly component of the required support force of parts 1 on x axle is component on y axle is further contemplate the t2 pressure P 2 of printing head to the parts 1 of printing constantly, suppose P2 vertically downward,, in order to guarantee the stress balance of parts 1, N2, G2, T2, P2 need meet: constraints based on above-mentioned equalising torque and stress balance, can determining means 1 applies position, direction and size at the constantly required support force T2 of t2; Further, constraints based on above-mentioned equalising torque and stress balance, a plurality of support force T2 may can be determined, a plurality of support force T2 that apply position, direction and/or vary in size, correspondingly, can therefrom select a support force T2, alternatively, select a support force T2 who makes stress N2 minimum.Need to illustrate, in some possible scenes: P2 is 0, such as after parts 1 have been printed; And/or N2 is 0, such as parts 1 without other parts of adjacency, other parts of parts 1 adjacency while all also not starting to print; And/or parts 1 directly contact with print platform, except above-mentioned various power, parts 1 may also be subject to the support force of print platform.In addition, if without the direction of considering support force T2, constraints that can be based on above-mentioned equalising torque, can determining means 1 applies position and size at the constantly required support force T2 of t2.

Comparison diagram 2A, 2B can find out, due to t2 parts 1 constantly than t1 parts more than 1 constantly the first half, in the gravity increase of parts 1 and center of gravity, move, be G2>G1 and L2>L1, therefore, parts 1 are greater than parts 1 in the moment of the constantly required support force T1 of t1 in the moment of the constantly required support force T2 of t2, correspondingly, than parts 1 t1 constantly required support force T1 apply position, direction and size, parts 1 apply position, direction and/or size and can change the constantly required support force T2's of t2.

In the present embodiment, alternatively, described according to the printer model file of an object, at least determine at least one parts in described object in the print procedure of described object required support force apply position and size, comprising:

According to the printer model file of an object, determine at least one parts in described object in the print procedure of described object required support force apply position, size and Orientation.

At least according to described required support force apply position, size and Orientation, control a contactless bracing or strutting arrangement and to described at least one parts, provide the active force that meets described required support force in described print procedure.

Wherein, the direction of the required support force of described at least one parts changes with described print procedure alternatively.

In the present embodiment, described contactless bracing or strutting arrangement has multiple implementation.

In a kind of optional implementation of contactless bracing or strutting arrangement, described contactless bracing or strutting arrangement comprises and is arranged on print area a plurality of ultrasonic transmitters around.Wherein, described print area refers to the region that at least one printing head in 3D printer can move at print procedure.

In the optional implementation of this contactless bracing or strutting arrangement, correspondingly, control described contactless bracing or strutting arrangement and in described print procedure, described at least one parts are applied to described support force and also have multiple implementation.

In a kind of optional implementation of control, describedly at least according to described required support force, apply position and size, control a contactless bracing or strutting arrangement and to described at least one parts, provide the active force that meets described required support force in described print procedure, comprising:
