Correspondingly, in 120 can be, at least according to the applying position of described required anchorage force and the concrete value control one noncontact formula bracing or strutting arrangement of size, at least one parts described are provided the same reactive force applying position and size in described print procedure, or, the condition at least met needed for the applying position of described required anchorage force and size, controlling a noncontact formula bracing or strutting arrangement provides at least one parts described in described print procedure and applies position and size meets the reactive force of described condition.

Can selection of land, control described noncontact formula bracing or strutting arrangement, in described applying position, at least one parts described applied the reactive force of described size.

In the present embodiment, the described reactive force that at least one parts described are provided by described noncontact formula bracing or strutting arrangement does not produce based on the contact of described noncontact formula bracing or strutting arrangement and at least one parts described. Can selection of land, described noncontact formula bracing or strutting arrangement does not contact with at least one parts described, further can selection of land, described noncontact formula bracing or strutting arrangement does not contact with other parts of described object. For example, the described reactive force that described noncontact formula bracing or strutting arrangement provides is it may be that the impulse force of gas or suction, and electric field is to the reactive force etc. of the electrical forces of electrified body, ultrasonic wave or light wave.

The present embodiment is by the printer model file according to an object, determine applying position and the size of the anchorage force that at least one parts in described object are required in the print procedure of described object, and control a noncontact formula bracing or strutting arrangement and in described print procedure, at least one parts described are provided the reactive force meeting described required anchorage force, provide the scheme that a kind of auxiliary 3D prints, specifically, the anchorage force of noncontact formula is utilized to replace the supporting structure printed to be supported by parts at least in part, save printing time and printed material, and avoid excision supporting structure to the impact of object outward appearance.

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

In the present embodiment, can selection of land, described printer model file includes but not limited to: the shape of described object, material, printing order. That is, in the printer model file of an object, at least describe the shape of described object, material and printing order. Specifically, the shape of described object comprises: form the structural relation between the shape of each part of described object and each part; The material of described object comprises: the material forming each part of described object; The printing order of described object comprises: the printing order forming each part of described object, namely first prints which part which part rear.

In the present embodiment, owing to there is stress between each several part adjacent in an object, correspondingly, it is possible to according to mutual stress, described object is divided into multiple parts (Parts). Owing to the stress between each several part adjacent in an object may change along with print procedure, can selection of land, the division of described middle parts of objects part also may change along with print procedure.

Wherein, some parts may need to support in print procedure, and some parts may not need to support in print procedure. Can selection of land, the present embodiment, at the described printer model file according to an object, before the applying position at least determining the anchorage force that the parts in described object are required in the print procedure of described object and size, also comprises:

According to described printer model file, it is determined that described object needs at least one parts described in support in described print procedure.

For example, for each parts, the center of gravity of these parts can be determined according to the shape of these parts, material, further, at least according to the structural relation of the adjacent each parts of the center of gravity of these parts and this parts and these parts, and the printing order of these parts and each parts adjacent with these parts, it may be determined that these parts are the need of support.

In the present embodiment, owing to there is stress between each parts adjacent in an object, and the printing order of each parts has successively, and therefore, in the print procedure of described object, each parts may all can change the need of anchorage force and required anchorage force. Can selection of land, it is necessary at least one parts of support change with described print procedure. Correspondingly, if at least one parts described change with described print procedure, and the anchorage force needed at least one parts described determined in 110 changes with described print procedure, then controlling described noncontact formula bracing or strutting arrangement in 120 provides, at least one parts described in changing with described print procedure, the reactive force met with the anchorage force needed for the change of described print procedure.

Can selection of land, the applying position of the anchorage force that at least one parts described are required in described print procedure and/or size change with described print procedure. For example, the applying position of described required anchorage force changes with described print procedure, or, the size of described required anchorage force changes with described print procedure, or, applying position and the size of described required anchorage force all change with described print procedure.

A kind of schematic diagram that Fig. 2 A, 2B are respectively in the application in print procedure not anchorage force needed for parts in the same time. It should be noted that, only with two vertical dimensional plane signals in Fig. 2 A, 2B, and do not mean that the restriction to the application. Fig. 2 A is the part object that a moment (representing with t1) prints out in the print procedure of described object that the printer model file according to an object is determined, Fig. 2 B is the part object printed out in another moment in described print procedure (representing with t2) determined according to described printer model file, t2 > t1, the part object printed out in t1, t2 moment includes parts 1 and parts 2.

As shown in Figure 2 A, in the t1 moment, parts 2 to parts 1 adjacent place produce stress N1, N1 is no more than the parts 2 determined by structure, material etc. to the maximum stress of parts 1, and the gravity of parts 1 is G1, and the distance at the adjacent place of the center of parts 1 and parts 1 and parts 2 is L1, namely the moment of the gravity of parts 1 is G1*L1, therefore, in order to ensure moment equilibrium, the moment of the anchorage force T1 needed for t1 moment parts 1 should be equal with the moment G1*L1 of the gravity G1 of parts 1; In addition, for two vertical dimensional planes, it is assumed that the component of stress N1 in x-axis isComponent in y-axis isThe component of anchorage force needed for t1 moment parts 1 in x-axis isComponent in y-axis isFurther contemplate t1 moment printing head to the pressure P 1 of the parts 1 printed, it is assumed that vertically downward, then in order to ensure the stress balance of parts 1, N1, G1, T1, P1 need to meet P1: Based on the constraint condition of above-mentioned moment equilibrium and stress balance, it may be determined that parts 1 are in the applying position of the anchorage force T1 needed for the t1 moment, direction and size; Further, based on the constraint condition of above-mentioned moment equilibrium and stress balance, may can determine multiple anchorage force T1, namely multiple anchorage force T1 that position, direction and/or size are different are applied, correspondingly, can therefrom select an anchorage force T1, can selection of land, select an anchorage force T1 making stress N1 minimum. Needs illustrate, in the scene that some are possible: P1 is 0, such as after parts 1 have printed; And/or, N1 is 0, when such as parts 1 all also do not start to print without other adjacent parts, other adjacent parts of parts 1; And/or, parts 1 directly contact with print platform, and except above-mentioned various power, parts 1 may also by the anchorage force of print platform. In addition, if without the need to the direction considering anchorage force T1, then can based on the constraint condition of above-mentioned moment equilibrium, it may be determined that parts 1 are in the applying position of the anchorage force T1 needed for the t1 moment and size.

As shown in Figure 2 B, in the t2 moment, parts 2 to parts 1 adjacent place produce stress N2, N2 is no more than the parts 2 determined by structure, material etc. to the maximum stress of parts 1, and the gravity of parts 1 is G2, and the distance at the adjacent place of the center of parts 1 and parts 1 and parts 2 is L2, namely the moment of the gravity of parts 1 is G2*L2, therefore, in order to ensure moment equilibrium, the moment of the anchorage force T2 needed for t2 moment parts 1 should be equal with the moment G2*L2 of the gravity G2 of parts 1; In addition, for two vertical dimensional planes, it is assumed that the component of stress N2 in x-axis isComponent in y-axis isThe component of anchorage force needed for t2 moment parts 1 in x-axis isComponent in y-axis isFurther contemplate t2 moment printing head to the pressure P 2 of the parts 1 printed, it is assumed that vertically downward, then in order to ensure the stress balance of parts 1, N2, G2, T2, P2 need to meet P2: Based on the constraint condition of above-mentioned moment equilibrium and stress balance, it may be determined that parts 1 are in the applying position of the anchorage force T2 needed for the t2 moment, direction and size; Further, based on the constraint condition of above-mentioned moment equilibrium and stress balance, may can determine multiple anchorage force T2, namely multiple anchorage force T2 that position, direction and/or size are different are applied, correspondingly, can therefrom select an anchorage force T2, can selection of land, select an anchorage force T2 making stress N2 minimum. Needs illustrate, in the scene that some are possible: P2 is 0, such as after parts 1 have printed; And/or, N2 is 0, when such as parts 1 all also do not start to print without other adjacent parts, other adjacent parts of parts 1; And/or, parts 1 directly contact with print platform, and except above-mentioned various power, parts 1 may also by the anchorage force of print platform. In addition, if without the need to the direction considering anchorage force T2, then can based on the constraint condition of above-mentioned moment equilibrium, it may be determined that parts 1 are in the applying position of the anchorage force T2 needed for the t2 moment and size.

Comparison diagram 2A, 2B can find out, owing to the parts 1 in t2 moment are than parts more than 1 upper part in t1 moment, the gravity of parts 1 increases and moves in center of gravity, i.e. G2 > G1 and L2 > L1, therefore, parts 1 are greater than the moment of parts 1 at the anchorage force T1 needed for the t1 moment in the moment of the anchorage force T2 needed for the t2 moment, correspondingly, compared to parts 1 in the applying position of the anchorage force T1 needed for the t1 moment, direction and size, parts 1 can change in the applying position of the anchorage force T2 needed for the t2 moment, direction and/or size.
