3D Printing Spray Painting Process Revealed: Creating a Perfect Surface!

3D printing spray painting, in simple terms, is to spray color on the surface of 3D printed models to achieve the purpose of beautifying, protecting and improving the texture of the model. This process can not only enrich the visual effect of the model, but also enhance its durability and practicality.

Overview of painting steps:

• Model preparation: First, make sure the surface of the 3D printed model is flat, without obvious defects and support structure residue.

• Surface treatment: Use sandpaper or grinding tools to polish the model to improve the adhesion of the paint.

• Primer spraying: Spray a layer of primer to enhance the adhesion and uniformity of subsequent paint layers.

• Color spraying: Spray the required color layer by layer according to design requirements.

• Detail processing: Finely spray specific areas to highlight the characteristics of the model.

• Protective paint spraying: Finally, spray a layer of protective paint to increase the gloss and wear resistance of the model.

There are many types of 3D printing spray paint, including glossy paint, matte paint, etc. Glossy paint is bright in color, suitable for showing the vitality and modernity of the model; matte paint gives people a low-key and calm feeling, suitable for some models that need to highlight the texture. Different types of spray paint have their own characteristics, and can be selected according to specific needs.

Common problems and solutions for painting

Question 1: What should I do if an orange peel effect appears on the surface of the model after painting?

Answer: For example, you print and spray paint a car model, and after finishing it, you find that the paint surface of the car body is not very smooth, and there are some small bumps, just like orange peel. This is because the paint is not evenly leveled when spraying. To avoid this, you can try to use multiple thin spray techniques, waiting for a few minutes after each spray to let the surface dry before spraying the next time. If the orange peel effect has already appeared, you can gently sand the surface of the car body with fine sandpaper above 1000, and then spray it again to get a smoother effect.

Question 2: After using for a period of time, the color of the painted model begins to fade or change. What should I do?

Answer: Suppose you have a carefully painted anime character model. After it has been placed in a display cabinet for a while, you find that the color of the model begins to fade and is no longer as bright as when it was first painted. This may be caused by the long-term exposure to the light in the display cabinet or the high ambient temperature. To solve this problem, you can consider replacing it with an LED cold light source to reduce heat generation, and regularly wipe the surface of the model with a soft cloth to remove dust. If the color has faded significantly, you can consider repainting it, or consult a professional at JLC3DP for help.

Question 3: If the paint on the model surface is cracked or peeling, how can I repair it?

Answer: For example, you have a 3D printed building model. After a period of display, you find that the paint on the corners of the model is cracked and peeling. This may be because the primer was not properly handled when spraying, or the paint layer was sprayed too thick. To fix this problem, you need to use a small brush to clean the cracked or peeling paint layer, then re-sand, apply primer, and spray paint using multiple thin sprays. If you are not familiar with these operations, it is recommended that you consult the professionals of JLC3DP for help.

Question 4: If a painted model is accidentally scratched or bumped during daily use, how can it be repaired?

Answer: Suppose you have a carefully painted drone model, and it is accidentally scratched by a sharp object during daily use, or it is bumped against a hard object during transportation. In this case, you can use a paint similar to the color of the model to do a partial touch-up. Before touch-up, make sure the surface of the model is clean and dry. After touch-up, keep the model ventilated and let the paint dry naturally. If the scratches are deep or the bumps are serious, it is recommended that you send it to a professional place for overall repair or repainting.
