Downfalls of PLA and Why it can be difficult to Paint 

Why is it difficult to paint PLA? One of the main reasons is that PLA is a thermoplastic. This means that it becomes soft and moldable when heated and hard when cooled. When you try to paint PLA, the heat from the brush can cause the PLA to deform.

Another reason why painting PLA can be difficult is that it doesn’t have a very smooth surface. The unevenness of the surface can make it challenging to get an even coat of paint without any streaks or lines.

Tips and tricks on how to paint your PLA print effectively.

PLA models are a great way to add some personality to your 3D prints, but they can be a little tricky to paint effectively. Here are some tips and tricks on how to get the best results when painting your PLA prints:

– start with a white primer coat – this will help the paint adhere better and give you a more even finish;

– use thin, even coats of paint – too much paint will make it difficult to achieve a smooth finish;

– be patient!

How to paint your PLA models:

1. Prepare the model

The first step is to prepare the model for painting. This involves cleaning the model and removing any dust or debris. You can use a damp cloth or a brush to clean the model. Once the model is clean, you can use a primer to help the paint adhere to the surface.

2. Choose the suitable paints

Many different types of paints are available, so choosing the right ones for your project is essential. If you are painting a model that will be used outdoors, you will need to use weather-resistant paints. If you are painting a model that will be displayed indoors, you can use any paint that you like.

3. Apply the paint

Once you choose the right paints, you can apply them to the model. It is crucial to apply the paint in thin coats. This will help to prevent the paint from cracking or peeling. You can use a brush or a sprayer to apply the paint.

4. Let the paint dry

Once you have applied the paint, you need to let it dry completely. This can take several hours or even overnight. Once the paint is dry, you can apply a clear coat to protect it.

5. Add details

Once the paint is dry, you can add any details that you like. This could include adding decals, weathering, or even painting in some of the details that were not included in the original model.

6. Enjoy your finished product

Once you finish painting your model, you can enjoy it for years. Your model will be a unique and beautiful piece of art you can cherish forever.
