How to Finish 3D Prints and Make Them AWESOME!

So 3D Prints are like ogres. They have layers. Those layers are very difficult to get rid of if you don't know what you are doing. Through this process of getting rid of the layers the print will become single colored and you will have to paint it if you don't like how it came out. Today in this tutorial I am going to show you how to get rid of those layer lines and paint a 3D Print.

You will need the following for this tutorial.

  1. A 3D Print.
  2. Spray Primer.
  3. Modeling or acrylic paint.
  4. Brushes.
  5. Paint thinner (Optional)
  6. Clear Spray Paint (Optional)
  7. Wire Brush (Optional)


    Lets get started!

Step 1: Primer!

  1. Put 2 - 5 coats of primer to cover the whole 3D Print.
  2. (Optional) If you have ever put 2 - 5 coats of primer on a 3D print, chances are that won't be enough to get rid of all the layer lines. To get rid of the layer lines entirely or at least mostly entirely since there will be always layers on it no matter how noticeable they are, you will need to brush primer on the spots that need it with a paint brush. The reason you do this over putting primer on the entire thing is that you don't want to get rid of too many details on it other wise you won't tell what the model is very well.

    TIP: I have glass jars filled with spray paint, a lid, and two or three small bearings or nuts in them. The reason for this is all I have to do is shake the can enough to not break it but mix the paint similar to shaking a spray paint can and that gives me paint to put on my brush for primer and not have to spray my brushes with a can.

Step 2: Wire Brush the Print (Optional)

You can wire brush the 3D Print for better paint adhesion but this is optional.

Step 3: Now for the FUN Part!

Next you need to paint the 3D Print. This will take time and patience to get good at. You can use paint thinner or Clorox wipes to clean up any mistakes. Or you can paint over the mistakes. It's all your choice. Just understand you won't get this right the first time so don't feel bad.

Step 4: Protective Coating (Optional)

Once when your print has dried for 24 hours now is the time to put a clear coat of spray paint on it.

Step 5: Enjoy!

Once when all the paint has dried it's done! Congrats! Please feel free to ask question or comments below if have any. I enjoy feedback. Thanks!
