PLA vs. ABS: Which Filament Is Better?

By
The term "3D printing" refers to an additive manufacturing process that can be utilised in a variety of contexts. It has been demonstrated to be extraordinarily useful for a wide variety of applications, including rapid prototyping, toys, medical devices, and plenty more. One of the most important things to think about when it comes to the process of designing and planning for your following 3D printed part or prototype is the type of 3D printer filament that you will use. The question of whether PLA or ABS filaments are more suitable for an application tends to be at the centre of the decision-making process for a significant number of designers.
When it comes to 3D printing, PLA and ABS are two of the most common types of filaments that are currently being used. In this blog, we take a more in-depth look at what PLA and ABS filaments are, as well as their key properties, and try to determine which filament would be best for your part or prototype.

What exactly are PLA and ABS filaments?

Polylactic Acid is what "PLA" stands for. Sugarcane and cornflour are two examples of the biodegradable sources that are used to create PLA, which is a thermoplastic material. PLA, which is a type of bioplastic, is frequently utilised for a diverse range of purposes. Because it is more rigid than ABS and nylon, PLA is frequently used in the process of 3D printing. PLA has a low resistance to heat and chemicals as a tradeoff for its other desirable properties.
Acrylonitrile Butadiene Styrene is what "ABS" stands for. Injection moulding is a typical application for ABS, which is a thermoplastic material. When compared to PLA, ABS possesses more desirable mechanical properties, in addition to being more durable, lightweight, and long-lasting. When it comes to 3D printing, ABS is a more difficult material to work with than PLA.


PLA vs. ABS 3D Printing Accuracy?

The accuracy of parts that are 3D printed is typically determined by the level of difficulty of the model being printed as well as the specific calibration of the printer being used. In addition, PLA and ABS filaments enable the creation of components that have a very high degree of dimensional accuracy. In point of fact, for interlocking components that are printed with PLA or ABS, tolerances of 0.5 millimetres and a minimum wall thickness of 1-2 millimetres are very much doable while still ensuring that the components have sufficient strength. It is also important to point out that because the printing temperature for PLA is lower than that for ABS, the material is less likely to warp after it has cooled. When it comes to the production of intricate features and sharp corners, PLA is therefore superior to ABS in this regard.

Knowing the Durability of PLA and ABS Filaments

PLA and ABS filaments have tensile strengths that are actually quite comparable to one another. Because of this quality, they are fantastic candidates for rapid prototyping. ABS is favoured by some engineers over PLA due to its superior ductility, despite the fact that both materials have comparable tensile strengths. ABS possesses greater flexural strength and elongation before it begins to break down, in comparison to PLA. As a consequence of this, ABS is an excellent choice for the production of the final part. If, on the other hand, you only need a filament for prototyping purposes, PLA is an excellent option because appearance is more important than performance in this case. To summarise, PLA filament is an excellent option for use in the production of parts that will not be subjected to significant amounts of physical force. On the other hand, the ABS filament is the material of choice if the application you are developing needs to be resistant to external physical forces.

Which Is a Better Choice for Your Application: PLA or ABS?

Choosing between ABS or PLA filaments for your 3D printed prototype or part depends on the specific requirements and use case for your application. It is by no means a one-size-fits-all decision and you should carefully weigh all the factors involved in each filament in order to make the best decision.
If aesthetics is one of your top priorities, PLA filaments are a good choice especially if your part has intricate or complex features. These characteristics make PLA ideal for prototypes. Additionally, toys, containers, and architectural mockups contain PLA.
For parts that need to be stronger and more heat-resistant, ABS is preferable. Additionally, ABS filaments are more resistant to corrosion compared to PLA filaments. ABS is great for applications involving moving parts, as well as for printing products such as phone cases and suitcases.
In terms of cost, there is not much difference between PLA and ABS filaments. Their pricing is some of the most economical amongst 3D printing material. For example, 10 meters of PLA and ABS each cost around five dollars. Color, brand, and shipping costs determine the price of PLA and ABS filaments.


In summing up, the decision regarding whether to use PLA or ABS filament is ultimately determined by the particular requirements and preferences of the user. It is generally agreed that PLA is the easiest filament to work with due to its lower printing temperatures, reduced likelihood of warping, and pleasant odour while being printed. On the other hand, ABS is known for its strength, durability, and resistance to heat, which makes it more suitable for functional parts due to these characteristics.
In addition, polylactic acid (PLA) is a material that is better for the environment because it is both made from renewable resources and is capable of biodegradation. On the other hand, ABS is not biodegradable and is derived from fossil fuels; as a result, it is not considered to be environmentally friendly.
In the end, both types of filament have their perks and drawbacks, and selecting one over the other will be determined by the requirements of the printing job at hand. It is essential to properly calibrate the printer and use the appropriate settings in order to achieve the best results, regardless of the type of filament that is selected to be used.

G-Code is an important part of 3D printing. Without it, your 3D printer wouldn't be able to print anything. Even now, a lot of people don't know what it is or how it works. In this blog, I'll talk more about what G-Code is and how it fits into 3D printing. By the end of this blog, you should know more about G-Code and how it works in the 3D printing process. What does G-Code mean? G-Code is a programming language that is used to control modern manufacturing equipment like CNC machines, 3D printers, and Laser Cutters. It is a list of commands that tell the machine how to move and what to do, like extrude material or change the temperature of the print head or change the bed temperature . In 3D printing, the slicer software takes your 3D model (an STL or OBJ file) and turns it into a set of instructions that the printer can understand. This is called G-Code. The instructions are then sent to the printer, which follows them layer by layer to make the final 3D-printed obj...
