PLA Print Quality Hacks

We assume you are already taking proper care of your filament (if not, check out Filament Care page). Now you want to improve the quality of your print? Follow the suggestions below to increase PLA print quality.


3D CAD Models

A little helpful advice that we have learned along the way, make sure to check that your 3D CAD model is watertight before calling it complete. Watertight basically means that there are no holes in your part’s surface. If you were to fill your part with water, would there be any leaks? Following this little suggestion will help ensure proper printing of your model.



When using ProMolt 3D filament, start off at a print temperature of 210°C. If the filament looks like it is leaking filament or your prints look stringy, then decrease the temperature in increments of 5°C until this no longer occurs. If the filament is not properly adhering to each previous layer and your prints look rough, then increase the temperature in increments of 5°C until this no longer occurs


Layer Height

Decrease layer height to increase the quality of your print. But be aware: this will increase the time of your print


Active Cooling

Use a fan during printing to actively cool recently extruded PLA material, which will improve overall finished print quality. This active cooling process not only allows for lower layer heights and sharper printed corners, but can also improve the strength of the part by strengthening the binding between layers.


Printing Surfaces

The best base surface quality will come from using a heated bed, but this is also one of the more challenging techniques to master. Clean the glass with denatured alcohol, heat the bed to 70°C, and place the extruder close enough to the glass where the PLA is sticking but not blocking the PLA extrusion process.
