How to choose LCD and DLP in the field of 3D printing?

DLP technology has a special advantage in that it can scale the model proportionally. That is to say, for the same model, if you print a 20cm model and a 2cm model, the precision of their finished products will not be significantly different. They can make models with small volumes but high requirements for details, but to be honest, the application range is relatively small. Another advantage is that the light source intensity of DLP is relatively high, so the curing speed will be faster and the relative printing speed will be faster.

The disadvantage is that printers using DLP technology are generally smaller in size and require replacement when the light source is depleted, resulting in high replacement costs


The advantage of LCD technology lies in its wide range of applications, which can basically meet the requirements of common 3D printing fields. Compared with DLP machines, it can have a large printing format, increase the number of prints in one go, and save time and cost. In the past, the accuracy of LCD may have been slightly lower than that of DLP, but now LCD can reach resolutions of 6K and 8K, and printing columns and circular holes with diameters of 0.2-0.3mm is not a problem. The difference between LCD and DLP is on the micrometer level, which can be ignored because the human eye's perception of millimeter level resolution is very low, let alone on the micrometer level. In terms of printing speed, LCD is indeed slower, but due to the increase in light intensity, the gap is currently very limited.

The disadvantage is that the LCD screen has a lifespan of around 2000 times. If the usage frequency is high, it is replaced almost once a year, which is much cheaper compared to replacing the light source with DLP.

Overall, DLP is more expensive, with higher accuracy, faster printing speed, but smaller size, fewer prints at once, and expensive replacement of light sources. LCD is cheaper, with relatively lower accuracy and printing speed, but it is larger in size and can print more at once, making it relatively cheaper to replace the LCD screen.
