Say hi to eSUN eResin-PLA Pro for black white screen LCD printer

Recently, mainstream printer manufacturers are promoting their own black and white screen 3D printers. This type of 3D printer has more advantages over conventional color screen LCD printers and will lead the market trend.

 

The advantages of conventional color screen 3D printers compared with black and white screen 3D printers are shown in the figure below.

In summary, the advantages of black and white screen LCD 3D printers are very obvious compared with conventional color screen LCD 3D printers, with higher light transmittance, 4 times the printing speed, and 5 times the screen life. However, when the photopolymer resin suitable for conventional color LCD printers used on black and white screen LCD 3D printers, the prints are prone to have residues, films, kelp, etc., and even incompatibility issues.

 

 

With the emergence of a large number of black and white screen LCD printers, users are calling for a suitable black and white screen resin. In response to the needs of users and fans, eSUN has launched this [eResin-PLA Pro bio-based high-precision resin] that is suitable for black and white screens in combination with the future development trend of LCD printing.

In 2017, eSUN was the first in the world to apply bio-based PLA polyols to LCD 3D printing, which reduced the odor and skin irritation of traditional photopolymer resins, and had a certain degree of biocompatibility, improved safety, which promoted the shift of LCD photopolymer resins to environmental resins and the popularization of LCD 3D printing.

 

eResin-PLA is safe and environmentally friendly, with high printing accuracy, good hardness, and scratch resistance; it has good hydrophobicity, dry surface, and is not easy to absorb moisture.

eResin-PLA Pro, in addition to retaining the characteristics of bio-based, low odor, and good hardness of eResin-PLA, it’s greatly improved in printing accuracy.

 

[eResin-PLA Pro bio-based high-precision resin] has low odor, good toughness, more balanced mechanical properties, fast printing speed, high precision, high resolution, and full texture. It can be adapted to small-size and large-size black-and-white LCD printers, as well as regular color screen LCD printers.
