DLP 3D printing technology can be said to be one of the relatively high standard technologies in 3D printing technology today. Compared with the most commonly used SLA 3D printing in the past, it has a relatively large printing accuracy, printing speed, and work stability. promote. The following is a simple comparative analysis from the three aspects of DLP 3D printing and SLA 3D printing.
1. Printing accuracy
In the past, when it comes to the printing accuracy of 3D printing, many people will think of SLA 3D printing technology. With the development of 3D printing technology, DLP 3D printing technology is also popular because of its better printing accuracy and printing speed. The printing accuracy is 4 times higher than that of traditional SLA, and it has been used in the dental medical industry to print some dental products and auxiliary dental treatment products.
2. Printing speed
One of the biggest differences between SLA and DLP is speed. The different ways of additive polymerization also make their speed far apart. SLA 3D printing is a dot-like aggregation method, which is usually very slow. While DLP 3D printing can cure the entire surface of the layer at one time, there is not much difference between the contour and the inner area, and it does not need to be cured again. For example, for the same 3D printing model file, using a DLP 3D printer, if it takes 30 minutes to complete the printing, then using an SLA 3D printer, it may take 4 hours. In contrast, the printing speed of the two can be intuitively compared. .
3. Work stability
For mass production, both SLA 3D printers and DLP 3D printers can be used for industrial mass production, but compared to SLA printers, DLP 3D printers have fewer moving parts in the work. Therefore, its The failure rate is lower, and stable model printing can be maintained. In general, the performance of DLP 3D printers on the market has been optimized and upgraded, and it is smarter and more stable than SLA 3D printers.
