Quand I looked around a room filled avec PLA impressions, I craved something new et plus challenging, so my gaze shifted to PETG filament. Le first step I took was exploring their différences. Ce est my experience from PLA to PETG.
vous do not devez a science degree to become an expert in imprimante 3Ds et filament d’impression 3D types. With our help, vous va get one step closer by understanding all vous devez to saurez sur PETG filament et PLA filament.
PETG ou PLA : Definition
To explain le différences, let us look at le basic filament definition for each material below.
Qu’est-ce que PLA?
PLA filament est a biodegradable type of plastic. Quand vous heat it up in votre imprimante 3D nozzle, it becomes flexible et once it cools down it va maintain its new shape. It est often made of ecologically friendly materials et has a reputation as being parfaites for beginners.
Qu’est-ce que PETG?
For personnes looking for a plus solid material that can withstand high temperatures or est suited for usage extérieur, PETG filament est a idéal alternative to PLA. Beginners va also be able to use it without issue, et plus avancé personnes can experiment avec settings to get a strong et durable print.
PETG ou PLA : Advantages
Every PETG filament est different, so today we va be looking specifically at Geeetech PETG filament, et examining those advantages compared to PLA filament in particular. vous might have lisez that PETG est stronger que PLA, but it est also idéal for impression 3Ds that use complex geometry, such as multiple bends or thin vases for instance.

PETG ou PLA : Disadvantages
Unfortunately, PETG est not a filament d’impression 3D that only offers up positives. Some users have experienced poor results avec their impressions because PETG est susceptible to humidité. Ce can be fixed by either storing le filament in sealed containers when not in use, or by drying le filament before use. Ici est a guide of 3d filament stockage et drying.
PETG ou PLA : Printing
Cheap filament pour imprimante 3D can lead to poorer models et imperfections, as well as bad adherence to le printer bed itself, maybe even ruining votre print altogether. So remember to look out for a trusted manufacturer avec good reviews when purchasing votre filaments.
Print Settings
Since le PLA melting point est typically around 150 to 160 °C, we va at least devez that temperature for our nozzle. Different manufacturers use slightly different ingredients et mixtures so for Geeetech filament, le below values can be used as recommendations for PLA filament:
| Extrusion nozzle temperature | 185°C - 215°C |
| imprimante 3D hot bed temperature | 25°C - 60°C |
| Fan speed | 80% - 100% |
| Fan speed for le first 1-2 layers | 25% - 50% |

For PETG filament, vous can use le below recommendations:
| Extrusion nozzle temperature | 220-240°C |
| imprimante 3D hot bed temperature | 80-90°C |
| First Layer Print Speed | 20 mm/s |
| Print Speed | 40 - 50 mm/s |

Print Quality
Le above paramètres d’impression should fournir vous avec good print qualité as a base point. It est a good idea to also check le description of le modèle vous sont impression, if vous download it from a public website. There vous va typically find conseils et astuces for settings to further improve votre print qualité. Of course, le qualité et surface of le impressions can also be changed through post-traitement.

PETG ou PLA: Pricing
Using Geeetech filament as an example, there est not much difference in le price:
|
1 kilogram of Geeetech PLA filament |
$9.79 |
| 1 kilogram of Geeetech PETG filament | $9.49 |
PETG ou PLA: Applications
Let us look at les deux types of filament d’impression 3D et some new applications in qui they have seen adoption in recent times.
Le Applications of PETG Filament
Since PETG filament est a durable material that can resist extreme temperatures et environments. Enhanced Geothermal Systems (EGS) has recently adopted it to meet le demands of that industrie. Ce est just one example of comment PETG est being used in cutting-bords heavy industries.
Le Applications of PLA Filament
PLA filament est biodegradable, but not really recommended or suitable for usage extérieur as PETG. Ce has led to innovations where PLA est used to help avec medicine stockage, food packaging et other areas where safety est critical et eco-friendliness helps le material see new adoptions regularly.

Conclusion
At le end of le day, nombreux impressions sont possible avec les deux PETG filaments et PLA filaments from Geeetech, et PLA est especially idéal for beginners et indoor projets, while PETG est a logical next step for personnes nécessitant a filament for plus demanding projets or impressions that va use a filament d’impression 3D to be used outdoors. Quand to use PETG ou PLA therefore relies on each specific project et it can be a good idea to have stocked up on les deux materials.
