Three-dimensional printer with a supporting element insertion apparatus

1. A method for forming a three-dimensional (3D) printed object, said method comprising:

forming, by a 3D printing device, a plurality of layers of the 3D printed object and a channel that extends through the plurality of layers, wherein the plurality of layers is formed of a first material;

identifying, by a sonar system or a light detection and ranging (LIDAR) system in the 3D printing device a specific location within the plurality of layers where the channel is located; and

inserting, by an insertion apparatus in the 3D printing device, a supporting element into the channel at the identified specific location, wherein the supporting element extends through multiple layers of the plurality of layers, and wherein the supporting element is formed of a second material that differs from the first material.

2. The method according to claim 1 , wherein inserting the supporting element further comprises inserting the supporting element while the supporting element is in a fluid state, and wherein the supporting element is to harden alter the supporting element has been inserted into the channel.

3. The method according to claim 1 , wherein the supporting element is a solid, elongated member and wherein inserting the supporting element further comprises inserting the supporting element to be frictionally fit into the channel.

4. The method according to claim 1 , wherein the supporting element is a solid, elongated element and wherein inserting the supporting element further comprises inserting the supporting element with an adhesive into the channel.

5. The method according to claim 1 , wherein the supporting element has helical grooves and wherein inserting the supporting element further comprises inserting the supporting element through application of a screwing action on the supporting element.

6. The method according to claim 1 , further comprising:

forming another plurality of layers while forming another channel that extends through the another plurality of layers, wherein the another plurality of layers is formed of the first material, and wherein the another channel is offset with respect to the channel;

identifying, by the sonar system or the light detection and ranging (LIDAR) system, a particular location within the another plurality of layers where the another channel is located; and. inserting another supporting element into the another channel at the identified particular location, wherein the another supporting element extends through multiple layers of the another plurality of layers, and wherein the another supporting element is formed of the second material.

7. The method according to claim 1 , wherein forming the plurality of layers is performed by a first material deposition apparatus in the 3D printing device, wherein the first material deposition apparatus is separate from the insertion apparatus that inserts the support element.

8. The method according to claim 1 , wherein forming the plurality of layers further comprises forming the plurality of layers through fused deposition modelling printing.

9. A method comprising:

forming by a three-dimensional (3D) printing device, a plurality of layers of a first material and a channel formed within the plurality of layers, wherein the first material is to form part of a 3D printed object;

identifying, by a sonar system or a light detection and ranging (LIDAR) system in the 3D printing device, a specific location within the plurality of layers where the channel is located; and

controlling a supporting element insertion apparatus to:

move to the identified specific location of the channel; and

insert a supporting element into the channel at the identified specific location, the supporting element being formed of a second material that differs from the first material.
