Abstract

Exemplary production methods for producing a paint plant component, e.g., for producing a component of a color changer, a color valve, or a spray device, are disclosed. According to the exemplary illustrations, the paint plant component may be produced in a rapid prototyping method. The exemplary illustrations also include a paint plant component that is produced accordingly.

First claim

The invention claimed is:

1. A method, comprising:
producing a component by rapid prototyping, wherein the component comprises a metal, a media-conveying through-line arranged to pass a fluid, and has at least one cavity filled with a support structure filled at least partially with a material having a lower mass density than metal; and
smoothing the surface of the component with surface-smoothing post-machining.

2. The method according to claim 1 , wherein the component is at least one of substantially free of dead space and substantially free of undercuts.

3. The method according to claim 1 , comprising the following method steps in the context of the rapid prototyping:
a) applying a first material,
b) solidifying the first material at predefined locations in order to form the component, the applied first material being only partially solidified,
c) removing the non-solidified portion of the first material,
d) applying a second material,
e) solidifying the second material at predefined locations in order to form the component, the applied second material being only partially solidified, and
f) removing the non-solidified portion of the second material.

4. The method according to claim 3 , wherein the different materials are applied by a print head that has at least one dedicated nozzle for each material.

5. The method according to claim 4 , wherein the rapid prototyping includes one of the following:
a) stereolithography,
b) selective laser sintering,
c) polyamide casting,
d) laser generation,
e) fused deposition modeling,
f) laminated object modeling,
g) 3D printing,
h) contour drafting, and
i) PolyJet.

6. The method according to claim 1 , wherein the component is produced by a combination of the rapid prototyping and a material-removing process.

7. A method, comprising:
producing a component by rapid prototyping, wherein the component comprises a shell made from a high-strength polymer, and a media-conveying through-line serving for passage of a fluid; and
subjecting the through-line to a surface-smoothing post-machining, wherein the surface-smoothing post-machining is one of pickling, honing, lapping, treatment with CO2 pellets or CO2 snow, and passing particles through cavities or channels in the painting plant component, the particles being suspended in a carrier liquid or contained in a carrier gas, the particles being selected from a group consisting of granules, beads, spheres, shaped parts or dust made from glass ceramic, aluminum oxide, polymers, nutshells, organic substances, sand or minerals.

8. The method according to claim 7 , wherein the rapid prototyping includes forming each of a plastic part and a metal part of the component.

9. The method according to claim 7 , wherein the component is selected from a group consisting of:
a) a color valve for a painting plant,
b) a component of an atomizer,
c) a component of a color changer,
d) a component of a metering pump,
e) a scaled-down model of a robot,
f) a scaled-down model of a painting booth,
g) a scaled-down model of a painting line,
h) a scaled-down model of a painting plant,
i) a scaled-down model of an atomizer,
j) a media-conveying part of a robot,
k) a robot component,
l) a channel or a pipe,
m) a component of a sealing device, and
n) a manifold for all colors from the color changer to the energy chain.

10. The method according to claim 7 , wherein the component is at least one of substantially free of dead space and substantially free of undercuts.

11. The method according to claim 7 , comprising the following method steps in the context of the rapid prototyping:
a) applying a first material,
b) solidifying the first material at predefined locations in order to form the component, the applied first material being only partially solidified,
c) removing the non-solidified portion of the first material,
d) applying a second material,
e) solidifying the second material at predefined locations in order to form the component, the applied second material being only partially solidified, and
f) removing the non-solidified portion of the second material.

12. The method according to claim 7 , wherein
the through-line is formed in such a way that the through-line is substantially free of kinks,
the through-line is formed in such a way that the through-line is continuously curved at least over a portion of its length, and
the through-line is formed in such a way that the fluid in the through-line flows in a laminar manner.

13. The method according to claim 7 , wherein at least one of the following materials are applied in the rapid prototyping:
a) polymers without fiber filling,
b) powder-based polymers,
c) electrically conductive or non-conductive polymers,
