Abstract

Disclosed is a control device for a 3D printer, which controls the 3D printer including a supply unit for supplying a forming material and a degradable agent, and a printing unit for printing a 3D object. The control device includes a display unit and a controller. The display unit outputs screen information for setting a use period of the 3D object. The controller controls the addition amount of the degradable agent, based on the set use period.

First claim

What is claimed is:

1. A system comprising:
a three-dimensional printer for printing a three-dimensional object, the three-dimensional printer including a body and a supply unit for supplying a forming material and a degradable agent formed inside the body; and
a control device communicatively coupled to the three-dimensional printer, the control device comprising:
a display unit for displaying screen information for setting a use period of the three-dimensional object;
a controller for determining an amount of the degradable agent to be added to the three-dimensional object based on the set use period and for generating a control signal for controlling the three-dimensional printer, the control signal being indicative of the determined amount of the degradable agent;
communication unit for transmitting the control signal to the three-dimensional printer; and
a memory for storing data of a printed three-dimensional object,

wherein the controller controls the display unit to display discard information for discarding the printed three-dimensional object based on the stored data;
wherein the forming material is composed of at least one of a first edible material or a second inedible material, and the degradable agent is composed of a plurality of degradable materials, and wherein the controller generates the control signal to control the three-dimensional printer to print the three-dimensional object with some of the plurality of degradable materials based on the first and second materials;
wherein, the display displays an available period of the three-dimensional object, the available period calculated based on the use period and a size or capacity of the three-dimensional object set by a user when the three-dimensional object is set to be formed of a biodegradable material degrading as time elapses, and wherein the controller determines the amount of the degradable agent to be added to the three-dimensional object based on the available period of the three-dimensional object and the use period set by the user.

2. The system of claim 1 , wherein the controller controls a size of the three-dimensional object based on a remaining amount of the forming material and the use period.

3. The system of claim 2 , wherein the screen information includes a control image for setting a number of three-dimensional objects, and
wherein the controller generates the control signal to control the number of the three-dimensional objects, the size of the three-dimensional object and the use period of the three-dimensional object.

4. The system of claim 1 , wherein the screen information includes a control image that includes a shape corresponding to the three-dimensional object, and
wherein at least one of a shape and a size of a portion of the three-dimensional object is changed based on a touch input applied to one area of the control image.

5. The system of claim 4 , wherein the control image corresponds to a portion of a photograph obtained by imaging an object.

6. The system of claim 1 , wherein the control device further comprises a camera for obtaining an image of an object,
wherein the controller sets a size of the three-dimensional object based on the image of the object obtained by the camera.

7. The system of claim 6 , wherein the memory further stores standard information of the imaged object,
wherein the controller sets the size of the three-dimensional object based on the standard information.

8. The system of claim 1 , wherein the display unit further displays a shape selected by a user, and
wherein the controller sets an internal structure recessed to correspond to the shape from one surface of the three-dimensional object.

9. The system of claim 1 , wherein the memory further stores information on a function and a shape of the three-dimensional object,
wherein the display unit further displays a function setting window including information on at least one function to allow the function of the three-dimensional object to be selected, and
wherein the controller generates the control signal to control the three-dimensional printer to print the three-dimensional object in a shape corresponding to the function selected by the function setting window.

10. The system of claim 1 , wherein the controller determines an amount of a degradation prevention material to be added to the three-dimensional object for suppressing the degradation when the three-dimensional object is set to include the first material based on the available use wherein the control signal generated by the controller is indicative of the determined amount of the degradation prevention material.

11. The system of claim 1 , wherein the display unit further displays an age input window for receiving a user's age when a component of the three-dimensional object is composed of the first material.

12. The system of claim 11 , wherein the controller changes a printing number of three-dimensional objects and a size or capacity of the three-dimensional object based on the user's age.

13. The system of claim 11 , wherein the controller determines an amount of an additive to be added to the three-dimensional object based on the user's age,
wherein the additive includes at least one of a vitamin element or a digestive element, and wherein the control signal generated by the controller is indicative of the determined amount of the additive.

14. The system of claim 11 , wherein the display unit further displays a password input window for receiving a password input by the user when the component of the three-dimensional object is composed of the first material, and
wherein the controller activates a locking function of limiting control of the three-dimensional printer when the input password does not correspond to a previously set password.

15. The system of claim 1 , wherein the display unit further displays a text input window for receiving a text formed on an outer surface of the three-dimensional object.

16. The system of claim 1 , wherein-the discard information includes a position where the printed three-dimensional object is discarded.

17. The system of claim 1 , wherein the stored data of the three-dimensional object include at least one of a printing date of the three-dimensional object, a material constituting the three-dimensional object, a use period of the three-dimensional object, or a use of the three-dimensional object.
