Now more common in 3D printing technology, PLA is a great 3D printing material and widely used, but it does have some drawbacks. For example, PLA has been criticized for being a bit too brittle and for absorbing some moisture.

Some might say that the next-generation alternatives to the PLA material are PETG or ABS. in general, both are stronger and more durable than PLA, but ETG and ABS don't work as well as one might think during the printing process, and the ease of use is not as good as that of PLA. nowadays, the next-generation that has emerged as the next-generation of PLA is PLA +, or PLA Plus, and PLA+ takes up the ABS.

Regarding the current PLA+ printing materials, UJOYBIO3D sells Elite PLA filament and Hyper PLA+ Filamento on behalf of the differences and advantages and disadvantages of PLA and PLA+, so that you can easily select the right printing filament for you.

Elite PLA filament series

UJOYBIO3D's Elite PLA filament series is a biodegradable thermoplastic polymer made from renewable resources with several easy-to-print material properties. These include low melting temperatures, good bed and layer adhesion, and a virtually non-existent odor that is virtually non-toxic.

Although in UJOYBIO3D mall, we order this series as Elite PLA Filament series, but the actual current series of finished product parameters and the quality of the market ordinary PLA + series have better places, so that the table of comparison parameters are our Elite PLA series and the United States brand Nanovia PLA series, Chinese brand SUNLU PLA+ series:

Filament parameters	UJOYBIO3D Elite PLA	Nanovia PLA	SUNLU PLA+
Tensile Strength	24.88MPa	No Required	58MPa
Tensile Modulus	2104MPa	No Required	2150MPa
Elongation at Break	2.4%	2.6%	3.6%
Flexural Strength	70.7MPa	58MPa	53MPa
Flexural Strength	2630MPa	No Required	2150MPa
Charpy impact strength	14KJ/m2	No Required	No Required
IZOD Impact Strength	13KJ/m2	No Required	35KJ/m
Density	1.32G/CM3	1.24 G/CM3	1.23G/CM3
Melt Flow Rate*	5-8G/10MIN	7–9G /10MIN	No Required
Heat Distortion Temperature	55℃	55 – 60°C	50℃
Printing Temperature	210-220℃	190 – 210          °C	205-215℃
Bed Temperature	N0/40-60℃	50-70℃	50-60℃
Printing Speed	300~500mm/s	50-100mm/	50-100mm/
Recommended Printing Temperature	220℃	No Required	No Required

 As you can see from the above table, the quality parameters of our Elite PLA series products, in some cases, have exceeded the performance of the other two, so the PLA quality of UJOYBIO3D can reach the PLA+ level of other brands.

Despite these qualities in the vast majority of PLA materials, PLA-printed parts exhibit several drawbacks, including brittleness and poor temperature resistance, and these are due to the relatively lower melting temperature of PLA materials. These characteristics result in PLA printed objects being less than ideal when used under pressure, whether it be temperature, physical loading conditions, etc.

Advantages of PLA materials

1. environmentally friendly:

PLA is made from plant-based raw materials and is biodegradable, making it an environmentally friendly material.

2. Printing ease of use:

Lower printing temperature (generally 190-220°C), lower requirements for printers.

Low thermal shrinkage, not easy to warp, suitable for printing large-area flat models.

3. No irritating odor:

The printing process will not produce obvious harmful gases and toxic odors.

4. good surface quality:

Printing surface is smooth, easy to spray or subsequent processing.

PLA material disadvantages

1. general mechanical properties:

PLA hardness but brittle, impact resistance is not strong enough, relatively hard when it will break.

2. Poor heat resistance

The heat distortion temperature is low (generally at 50-60°C, i.e. 160-180°F), and it is easy to soften or deform under high temperature.

3. Easily aging after long time use

In high humidity environment, it will absorb moisture and degrade, and the strength will decrease.

Applicable scenes of PLA material

Used for decorative parts, model displays, educational products, toys and other applications that do not require high mechanical properties.

Hyper PLA+ filament series

UJOYBIO3D's Hyper PLA+ filament series is a big improvement on PLA, the ordinary PLA+ on the market than by adding other materials (such as TPU, ABS or other additives) to improve performance. In UJOYBIO's R&D team, the company uses advanced technologies such as biodegradable polymer materials, material synthesis and modification technologies, and clean energy to produce Hyper pla + filament, which is made from high quality plant-based starch materials, with optimized polymerization process, by regulating the catalyst type and dosage, the material ratio and dosing method, the polymerization temperature, and other process conditions, to achieve high molecular weight, narrow molecular weight distribution of PLA + material continuous preparation, in the printing process emits low smoke content, and no irritating odor. Therefore, PLA+ materials produced by UJOYBIO have the following characteristics.

PLA+ Advantages

1. Higher strength and toughness

PLA+ is usually more impact resistant than ordinary PLA, the bending strength reaches 77.7MPa, not easy to break, the tensile strength is 66.1MPa, the elongation at break is 21MPa, the ductility is better, and the toughness is 60% higher than that of ordinary PLA+ materials in the market.

2. Better heat resistance

Some PLA+ can remain stable in environments above 70°C, suitable for printing parts that require high temperature resistance.

3. More stable printing results

Compared to the pla series, the pla+ series has a lower warpage rate and fewer drawing problems, with speeds up to 500mm/s and a high print success rate.
