PLA vs PLA+: Differences
Both PLA and PLA+ are popular in the 3D printing industry. While they share many similarities, each has its distinct characteristics. In this article, we'll compare PLA with PLA+ to help you decide which is correct. We'll also evaluate the top 3D design software to help you make an informed decision when entering the world of 3D.
PLA refers to polylactic acid, a biodegradable thermoplastic derived from renewable resources like cornstarch. There are several advantages to PLA. However, PLA+ improves upon it in several ways.
What is PLA and What Are Its Characteristics?
PLA is a biodegradable and bioactive thermoplastic made from renewable resources like cornstarch or sugarcane. It is one of the most popular materials used in 3D printing for several reasons:
1. Biodegradable: One of the most significant advantages of PLA is that it is compostable at industrial composting facilities. This makes it a more environmentally friendly option compared to other plastics.
2. Low melting point: It has a low melting point of around 180-220°C, making it easier and safer to work with, particularly for 3D printing beginners.
3. Odorless: Unlike some other materials that emit a strong odor when melted, PLA is relatively odorless, which is a plus for home or classroom use.
4. Strength: PLA is relatively strong but is more brittle compared to materials like ABS or PETG. It's sufficient for many applications but may not be suitable for mechanical parts or items that will be exposed to high stress or heat.
5. Food Safety: Some grades of PLA are considered food-safe, although it's essential to consider other factors like the safety of the 3D printer and dyes used in the filament.
What is PLA+ And It's Characteristics
PLA+ is an enhanced version of PLA filament. While both are derived from organic materials like cornstarch or sugarcane, PLA+ goes through additional processing or includes additives that make it different from its standard counterpart. It has the following characteristics:
1. Increased Strength: PLA+ is generally tougher and has a higher tensile strength compared to regular PLA. This makes it more suitable for applications where additional durability is needed.
2. Better surface finish: Objects printed with PLA+ often have a smoother, shinier surface finish, which can be aesthetically pleasing and may reduce the need for post-processing.
3. Reduced brittleness: One of the drawbacks of standard PLA is its brittleness, and PLA+ addresses this issue by being less prone to cracking under pressure.
4. Improved Layer Adhesion: The enhanced formulation of PLA+ often leads to better layer adhesion, making it less likely for prints to delaminate.
5. Heat resistance: While PLA+ doesn't drastically improve heat resistance, it can perform slightly better than standard PLA under elevated temperatures.
Difference Between PLA and PLA+
1. Durability
PLA+ is more durable than PLA. Due to improved layer-to-layer adhesion, PLA+ prints are more resistant to stress-related failure. Because of this, printing valuable parts or products that need more strength with PLA+ is preferable.
2. Flexibility
When compared to PLA, PLA+ is more malleable. This is because PLA+ can be bent without breaking, thanks to its increased elongation at break. In contrast, PLA is less plastic and more rigid. PLA+ is the superior material for printing flexible phone covers and hinges.
3. Surface Finish
Improved layer adhesion gives PLA+ a smoother surface finish than PLA. There are fewer clear layer lines on the surface of the printed object thanks to the enhanced adhesion between the layers. The feeling of PLA is similarly smooth, though the layer lines may be more noticeable.
4. Printing Temperature
Compared to PLA, the temperature range for printing with PLA+ is much broader. Since PLA+ requires a higher printing temperature, faster printing speeds are possible without sacrificing print quality. In contrast to PLA, which can be printed at temperatures between 190 and 220 degrees Celsius, PLA+ requires temperatures between 200 and 240 degrees Celsius, which may necessitate a more advanced 3D printer with a heated bed.
5. Cost
There is a significant price difference between PLA and PLA+. Because of its accessibility and popularity, PLA is frequently used in 3D printing. It makes it more accessible and less expensive than PLA+. Due to its scarcity and relative novelty, the cost of PLA+ tends to be higher than that of PLA.
6. Printing Speed
With its enhanced layer adhesion and higher printing temperature range, PLA+ allows faster printing speeds than PLA. In other words, PLA+ allows for shorter printing times than PLA. Finding the optimal speed at which to print without sacrificing quality is, of course, crucial. The maximum printing speed for PLA is 60mm/s, whereas the maximum for PLA+ is 100mm/s.
7. Post-Processing
PLA+ is simpler to process than PLA. It has better layer adhesion and a smoother surface finish, making sand, paint, and polish easier. Post-processing PLA is also possible, albeit it may take more work to get the desired look. The improved surface quality of PLA+ facilitates post-processing, resulting in a sleek and refined appearance.
8. Environment-Friendly
PLA and PLA+ are eco-friendly since they are produced using renewable resources and decompose in the environment. However, PLA is better for the environment than PLA+ because it uses less energy during production and can be recycled more easily. Both PLA and PLA+ originate from either cornstarch or sugarcane, although the latter also incorporates additional materials. In comparison to PLA+, the production of PLA uses less energy, making it a more eco-friendly choice.
9. Odor
Due to its higher printing temperature range, PLA+ may emit a more pungent smell than PLA while printing. Although this odor is harmless, it could be unpleasant, so good ventilation in the printing area is essential. Both PLA and PLA+ emit an aroma described as mildly syrupy. It's harmless; however, it might be more evident because of the increased printing temperature required by PLA+.
10. Storage
PLA+ absorbs more moisture during storage than PLA. It becomes fragile and difficult to print on if it gets wet. Therefore, appropriate storage is essential. PLA is similarly susceptible to moisture damage, though it absorbs less of it than PLA+ does. Both PLA and PLA+ benefit from being stored in a dry, relaxed environment, free of humidity. Both should be kept in airtight containers with desiccant packs.
Your 3D printing project's needs will dictate whether you use PLA or PLA+. Regarding strength and flexibility, PLA+ is the superior material, but PLA is the ideal material for surface finish. Both PLA and PLA+ are biodegradable and good for the environment. However, PLA is more eco-friendly. When deciding between PLA and PLA+, consider factors like printing speed, post-processing, odor, and storage needs.
