PLA (polylactic acid) filament is a common 3D printing material, which is favored by 3D printing enthusiasts for its environmental protection, ease of use and multiple color options. Among them, the 1.75mm diameter PLA filament is the most popular specification. This article will introduce the characteristics of 1.75mm PLA filament in detail to help readers better understand and use this material.

Environmental protection property

The main raw material of PLA filament is renewable resources such as cornstarch or sugar cane, which makes it more environmentally friendly than traditional petroleum-based plastics in the production process. The biodegradability of PLA material also means that it has less impact on the environment after waste. In addition, PLA produces a relatively small odor during the printing process, unlike some other materials (such as ABS), which can produce pungent odors, so it is more suitable for use in closed environments such as homes or offices.

Ease of use

The 1.75mm PLA filament usually does not require a heating bed when printing, or only requires a lower temperature, which reduces the difficulty and energy consumption of printing. Its printing temperature is generally between 180C and 230C, which is relatively low, reducing the burden on the printer and extending its service life. Due to the good thermal stability of PLA material, it is not easy to deform or crack during the printing process, making the printing success rate high.

Mechanical property

Although the mechanical properties of PLA filament are not as good as engineering plastics such as ABS, it still has a certain strength and toughness. PLA material is suitable for making some models or prototypes that do not need to bear too much force, such as display models, cultural and creative products. Its hardness is moderate, easy to carry out subsequent cutting, drilling and other processing.

Color and surface effects

PLA filament has a rich choice of colors, from standard colors to fluorescent colors, transparent colors, etc., to meet the needs of different users. In addition, the surface effect of PLA prints is usually smooth and does not require too much post-processing to obtain a better appearance. This makes PLA an ideal choice for making appearance or display pieces.

Precision and detail

The 1.75mmPLA filament can achieve high printing accuracy and is suitable for the production of more complex models. Due to the low shrinkage rate of PLA material during the curing process, the dimensional accuracy of the model can be better maintained. This makes PLA excellent when making precision parts or works of art.

cost-effectiveness

PLA filament has a relatively low cost and is an ideal starter material for beginners and small studios. In addition, due to its ease of printing and low failure rate, the overall cost of use is further reduced. The wide availability of PLA materials also means that users can easily purchase PLA filaments in a variety of brands and qualities.

Application field

1.75mmPLA filament is widely used in the fields of education, prototyping, art creation and home decoration. In the field of education, PLA has become the material of choice for 3D printing courses in schools due to its safety and ease of use. In prototyping, PLA can help designers quickly realize design concepts and carry out design verification. In the field of art creation and home decoration, the colorful and malleable nature of PLA provides a rich creative space for artists and designers.

limitation

Although PLA filament has many advantages, it also has some limitations. For example, PLA has poor heat resistance and generally begins to deform at around 60C, which is not suitable for making parts in high temperature environments. In addition, the mechanical strength and wear resistance of PLA are not as good as some engineering plastics, limiting its use in some industrial applications.

1.75mm PLA filament is an environmentally friendly, easy to use and versatile 3D printing material suitable for a wide range of application scenarios. Its printability, low cost, and rich color options make it ideal for beginners and professional users alike. However, when choosing PLA as a printing material, it is also necessary to consider the limitations of its heat resistance and mechanical properties to ensure that it is suitable for specific application needs. With reasonable selection and use, PLA filaments can play a huge potential in the field of 3D printing.
