PLA vs PETG, what is best?
What is best PLA or PETG?
More and more people are moving towards using PETG instead of PLA, so in this blog post we are going to look at why! Which is best PLA or PETG?
PLA (Polylactic Acid) is a polyester plastic and is a consumer favourite for 3d printing, for most first-time printer’s PLA is the go to filament to test and play before venturing on to more difficult materials.
PETG stands for “Polyethylene terephthalate glycol-modified” and the normal reputation is that it is as easy to print as PLA but has the physical properties of ABS, which sounds perfect!
PLA vs PETG Summary:
- PETG is more expensive than PLA.
- PLA normally has a wider range of colours.
- PLA is slightly easier to 3D Print than PETG. This is due to PLA being more forgiving when it comes to settings
- Both PETG & PLA, have minor shrinkage during cooling.
- Both are considered to be food-safe, however the tiny gaps between layers can harbour bacteria.
- Both are user friendly, however PETG is more durable, stronger and is impact resistant.
- Technically, you don’t need a heated bed to print both materials. Although I would recommend one.
- PETG is more heat resistant than PLA.
So in summary if you are a beginner PLA is a safe choice, but if you are feeling adventurous and want to make usable parts PETG is your best bet.
