Polylactic Acid For 3D Printing

As an environmentally friendly and high-performance 3D printing material, PLA has outstanding performance in many fields. The following is a detailed introduction to the relevant situation:

1. The core advantages of PLA materials Outstanding environmental protection characteristics: PLA is made of renewable plant resources such as corn and sugarcane. It can be naturally degraded into carbon dioxide and water under industrial composting conditions. It can effectively reduce the "white pollution" caused by traditional plastic 3D printing materials to the environment, which is in line with the current green and environmental protection development concept. Excellent printing performance: PLA has a low melting point (about 150-160℃), good fluidity during 3D printing, easy to shape, and not prone to warping during printing. It can ensure that the printed product has high precision and good surface finish, and can meet the appearance and size requirements of most products. 
Rich color selection: We provide a variety of PLA materials, including common basic colors such as red, yellow, blue, black, and white, as well as some special gradient colors, fluorescent colors, etc. You can choose the right color according to your needs to make the printed product more personalized. 
Safety is guaranteed: PLA materials are non-toxic and non-irritating. They will not release harmful gases during the printing process. They are friendly to human health and the working environment. They are especially suitable for making products that come into contact with the human body, such as toys and daily necessities. ​

2. 3D printing scenarios suitable for PLA materials​
Prototype production: Whether it is a conceptual prototype in the early stage of product design or a functional test prototype, PLA materials can quickly and accurately convert design drawings into physical models, helping you to intuitively understand the appearance and structure of the product, and facilitate timely design optimization.​
Crafts and cultural and creative products: With rich colors and good formability, PLA materials are very suitable for making various crafts and cultural and creative products, such as ornaments, key chains, decorative paintings, etc., which can well show the details and artistic sense of the products. 
Education and scientific research: In the field of education, PLA materials can be used to make teaching models to help students better understand abstract knowledge; in the field of scientific research, it can be used to make experimental samples, small equipment parts, etc., to facilitate research work. ​
Personalized customized products: For example, customized mobile phone cases, accessories, small household items, etc., PLA materials can meet your needs for product uniqueness and let you have exclusive items. ​

3. Related parameters and precautions for 3D printing of PLA materials​
Main printing parameters: It is recommended to set the nozzle temperature at 190-210℃, the hot bed temperature at 50-60℃ (adjusted according to the specific model and product), and the printing speed can be selected between 30-80mm/s according to the product accuracy requirements.​
Note: PLA materials are highly hygroscopic and need to be sealed during storage to avoid moisture affecting the printing quality; if the material is damp, it is recommended to dry it before use (generally dry it at 60°C for 2-4 hours). After printing, the product should avoid being exposed to high temperature for a long time to prevent deformation.
