## Abstract

A 3D printing device includes at least one printing nozzle for a layer-by-layer application of a printing material provided for the production of a component to be printed along a direction of application (R). The 3D printing device has a temperature control device that is configured and provided both to cool and warm already applied printing material in the region of the printing nozzle.

## Claims

### Claim 1

A 3D printing device comprising:
at least one printing nozzle configured to provide a layer-by-layer application of a printing material for the production of a component formed by printing along a direction of application; and
a temperature control device configured to cool and warm already-applied printing material,
wherein the temperature control device includes,
a ring-shaped support including a number of sections and extending around the at least one printing nozzle,
a first plurality of temperature control elements configured for cooling the already applied printing material, and
a second plurality of temperature control elements provided for warming the already applied printing material, wherein the first and second plurality of temperature control elements are provided on each of the number of sections of the ring-shaped support.

### Claim 2 (depends on 1)

The 3D printing device of claim 1, wherein the temperature control device is configured to generate at least one fluid flow with a warmed fluid and at least one fluid flow with a cooling fluid for warming and cooling the applied printing material, respectively.

### Claim 3 (depends on 2)

The 3D printing device of claim 2, wherein the first and second plurality of temperature control elements include at least one outflow opening for the warming fluid and the cooling fluid.

### Claim 4 (depends on 3)

The 3D printing device of claim 3, wherein the at least one outflow opening includes a first outflow opening for generating warming fluid flow provided to warm the printing material and a second outflow opening for generating a cooling fluid flow provided to cool the printing material.

### Claim 5 (depends on 3)

The 3D printing device of claim 3, wherein the temperature control device includes at least two supports wherein the at least two supports include the ring-shaped support.

### Claim 6 (depends on 2)

The 3D printing device of claim 2, wherein the temperature control device includes at least one valve configured to control at least one of an inflow of different fluids and an inflow of a fluid via different fluid paths.

### Claim 7 (depends on 6)

The 3D printing device of claim 6, wherein the at least one valve is further configured to control an inflow of a warmed fluid via a fluid path of the different fluid paths that is different than another fluid path of the different fluid paths of the inflow of a cooling fluid.

### Claim 8 (depends on 1)

The 3D printing device of claim 1, wherein the temperature control device includes at least one emitter configured to warm the already applied printing material.

### Claim 9 (depends on 1)

The 3D printing device of claim 1, wherein the temperature control device includes an electronic control system configured to control warming or cooling depending on the direction of application in which the printing nozzle is shifted.

### Claim 10

A 3D printing device comprising:
at least one printing nozzle configured to provide a layer-by-layer application of a printing material for production of a component to be printed along a direction of application; and
a temperature control device including,
a first ring-shaped support,
a second ring-shaped support, the first and second support extending around the printing nozzle,
a first plurality of temperature control elements provided for cooling already applied printing material, and
a second plurality of temperature control elements provided for warming the already applied printing material, wherein the first and second plurality of temperature control elements are provided on each of the first and second ring-shaped supports of the temperature control device.

### Claim 11 (depends on 10)

The 3D printing device of claim 10, wherein the temperature control device includes an electronic control system configured to employ different temperature control elements of the first and second plurality of temperature control elements depending on in which direction of application the printing nozzle is shifted.

### Claim 12 (depends on 10)

The 3D printing device of claim 10, wherein the first ring-shaped support is arranged concentrically with the second ring-shaped support.

### Claim 13 (depends on 10)

The 3D printing device of claim 10, wherein the temperature control device includes a third ring-shaped support.

### Claim 14 (depends on 13)

The 3D printing device of claim 13, wherein the third ring-shaped support includes outflow openings for an inert process gas.
