PLA Filament

Filament called lactic polyacid, or PLA, as it is generally known among users of 3D printers, is created from biodegradable or renewable resources such as corn starch. This material does not emit noxious gases, so it is used in food packaging.

Objects printed with PLA filaments are much more fragile and have a much shorter shelf life, because they are biodegradable materials and their properties are lost faster.

Nor will it be possible to perform a post-processing of the piece such as, among others, molding, drilling or painting parts. The objects manufactured with this filament support worse temperatures than other materials since the PLA has a main disadvantage, is its low thermal resistance (60-70) ºC. This makes this plastic material little useful for those parts that need to withstand high temperatures.

The PLA when it is fused generates a pleasant and non-toxic smell, since the PLA is made from corn. This makes it ideal for prints in homes and especially in surroundings frequented by many people.

Another advantage over ABS is that it does not require a warm bed so that it has good adhesion and can be printed.


ABS Filament

The styrene acrylonitrile butadiene filament, or ABS, as commonly known among users of 3D printers, is a petroleum-derived thermoplastic. This material has properties that endow the piece with a greater hardness compared to one made in PLA, is able to withstand temperatures below -20ºC and above 80ºC.

It is much more rigid, resistant to chemical attacks, hard and stable at high temperatures, in addition, can suffer a post-processing after printing among others can be machined, polished, sanded, file bored, painted or glued without major setbacks.

ABS becomes the most versatile option when creating your own objects in a 3D printer by many users, although this filament requires having the printer ready, as it requires a warm bed to adhere to the surface, which is the PLA does not need.

Another disadvantage of ABS against the PLA is that it emits toxic gases when it is melted, giving an unpleasant smell in the environment.
