Can you paint PLA 3D printed objects?
Whether you have chosen to sand your model and apply filler or you are simply painting a rough PLA model printed at high resolution, a few layers of primer/filler will fill any small surface imperfections before painting.
What’s better PLA or ABS?
PLA is stronger and stiffer than ABS, but poor heat-resistance properties means PLA is mostly a hobbyist material. ABS is weaker and less rigid, but also tougher and lighter, making it a better plastic for prototyping applications.
Can PLA be sanded?
Poorer quality PLA isn’t as easy to sand as higher quality. So if you are going to sand PLA, you’ll save yourself hassle printing with high quality filament. Now to the sanding. To start, you’re going to need a selection of fine grit sandpapers.

Does acetone affect PLA?
Acetone is a popular choice for removing 3D-printed parts from the build plate and clean up. It is true that acetone dissolves PLA at a certain level. While there isn’t one particular solvent that does the job for all types of PLA filament, it is possible to get good results with some other solvents.
Can 3D printed plastic be painted?
Both acrylic and water-based paints work as well, but several layers may be needed. Please, do not use any harsh paints because some chemicals may degrade your models or react with the 3D printing materials.
What is a good primer for plastic?

One constant that is commonly found in most surface smoothing methods for PLA is sandpaper. You can gradually move through a variety of different grit sizes to obtain a smoother surface. It works, but repeatedly grinding down your print with sandpaper can be a timely and exhausting exercise.
Why are my 3D prints not smooth?
The best way to fix 3D printed walls that are not smooth is to identify over-extrusion or under-extrusion issues that you are experiencing and tackle them by changing settings such as retraction or lowering printing temperature. Fixing vibration issues can solve walls that are not smooth.
