Makerbot is known for the high standards met by its products. Its PLA filament is no exception, as it’s pretty much the best PLA available on the market. This filament ensures high quality outputs at a reasonable price. Unfortunately though, this excellent filament is only available with a 1.75mm diameter.
Ranked in these QuestionsQuestion Ranking
Pro Above average mechanical parameters
Since this filament was designed to be used with high-end, expensive Makerbot hardware, its mechanical parameters exceed the standards for regular PLA plastic, as shown in the raw datasheet of the material. It's properties are very well balanced; the filament is quite ductile, meaning tensile strength is a bit higher than that of standard PLA, while maintaining the same high material elasticity. While it isn’t a groundbreaking filament, you can be assured that there is no aspect of this product that can be considered substandard.
Pro Has proven its value with the 3D printing community
As most Makerbot products, this filament has earned some popularity within the 3D printing community. While Makerbot recommends this filament with their own 3D printers, plenty of people have used this filament for non-Makerbot printers and are quite satisfied with the quality of the results.
Pro Health risks are lower than with ABS
3D printing PLA poses fewer health risks than ABS.
Pro No heated bed required
Using a PLA filament does not require your 3D printer to have a heated bed.
Pro Available in 10 different colors
This filament is available in 10 different colors, all of which offer consistent quality and looks.
Pro Proper packaging protects filament from mechanical damage, air and humidity
Makerbot’s packaging keeps the filament inside safe from damage The thick cardboard box protects from mechanical damage while the vacuum-sealed film (together with an included silica pack) keeps the filament safe from air and humidity. This is very important, as filaments absorb water extremely fast.
Con PLA's applications for 3D printing are quite limited
In terms of 3D printing applications, PLA is very limited. While it’s great for general prototyping and poses fewer health risks, it cannot withstand hot or humid environments: it degrades dramatically when exposed to direct sunlight, high temperatures (above 60ºC) or water. It is way less durable and flexible than materials like ABS and lacks chemical resistance. You need to be aware of what the limits are when using this material.
Con Impossible to be used with a 3.0 mm extruder
If your printer has a 3.0 mm extruder, you won't be able to use this filament, since it only comes in 1.75mm form. For Makerbot, this is justifiable, since all of their hardware uses 1.75 mm.
