5 Useful Tips to 3D Print with PLA Filament

One-Minute Read:

PLA (polylactic acid) is a widely used 3D printing filament made from renewable resources such as corn, sugarcane, tapioca, and starch.

It is popular for prototyping, jigs, fixtures, and demonstration models because it is easy to use, requires minimal post-processing, and produces fewer toxic emissions.

This article explains what PLA is and shares five practical tips for better print results: use the right print temperature, watch for stringing, make sure layers adhere properly, adjust for low viscosity when needed, and keep the filament dry during storage.

Together, these tips help improve print quality, part strength, and overall printing consistency when working with PLA filament.

What is PLA Material?

Polylactic acid, also known as PLA, is a high-performance thermoplastic polyester created from renewable resources.

Corn, sugarcane, tapioca, and starch are some of the natural ingredients used to make this product.

PLA is one of the few materials that can be composted in an industrial setting. This implies PLA decomposes more quickly.

PLA plastic is extensively used in a variety of sectors, and it’s a good material for beginners because it requires little maintenance and minimum post-processing.

Furthermore, because this additive printing material has a low thermal contraction, the product doesn’t deform and remains stable at high temperatures.

5 Tips To 3D Print Objects Effortlessly With PLA

It is important to understand how to use the PLA filament before you start additive manufacturing.

So, we have come up with this guide, which will help you use PLA filament while printing without any significant issues. Here are our top 5 tips.

1. Control The Temperature

It is critical to use the correct temperature while printing with PLA material. An ideal temperature is 195°C. This will increase your chances of success while you 3D print.

You can adjust the temperature in 5-degree increments until you get to the desired print quality and strength that complement each other.

There are a few PLA plastics that can be produced at a lower temperature, as they contain a higher percentage of pure resin with fewer contaminants.

So, to improve the sticking, you must heat the construction plate to 60 degrees.

2. Keep An Eye Out for Stringing

Stringing means that the temperature of the 3D printer is too high. The extruder will leak out the PLA filament when moving between different areas of the printer, hence causing stringing.

So, when this happens, you will have to decrease the temperature. Until the extruder stops leaking the filament, you can continue to decrease the temperature by 5 degrees per step. 

3. Ensure The Layers Are Adhering

If the printing temperature is too low, the filament will not stick to the preceding layer. This will result in a rough-looking and uneven feeling surface.

It could also indicate that the part is weaker and hence can be more easily separated.

If this happens, increase the printhead temperature by five degrees at a time until the printing looks perfect, and the line segments are just right for each layer.

As a result, when the job is finished, the part will be stronger.

4. Viscosity Should Not Be Low

Some PLA filaments may have a lower level of viscosity as compared to other varieties of PLA material. As a result, leaks will be more frequent, even at lower temperatures.

If this is the case, you should raise the retraction by a few millimetres.

Although you may alter the retraction distance in printing software, it is preferable to seek professional assistance in this situation.

5. Keep The PLA Filament Dry

It is important to store PLA filament in a cool and dark place. Make sure it is packed away in a sealed bag before storing it, as it will help preserve the PLA material’s quality for a longer period.
