At present, the mainstream technologies used by the UV curing 3d printer on the market are SLA, DLP and LCD, among which LCD is the most common UV curing 3d printer on the market. At present, let's talk about the advantages and disadvantages of the current LCD light curing 3d printer:



First of all, advantages:

1、 The LCD light curing 3d printer has high printing accuracy. Generally, it uses a 4K or even 8K resolution transparent screen, which can easily reach the accuracy of 100 microns, and is technically superior to SLA technology. As far as the current situation is concerned, if the industrial level is not considered, only the DLP can be compared with the LCD in terms of accuracy;
2、 The price is cheap. LCD is an open source technology. At the same time, the components on the device are much cheaper than SLA and DLP. It is the most cost-effective light curing 3d printer at present;
3、 It is easy to get started and maintain. There is no such projection module as SLA's laser galvo or DLP. LCD can be assembled with a high-resolution light transmission screen and Z-axis module. Its architecture is simple and maintenance is easy;
4、 Consumables are universal. The LCD uses 405mm ultraviolet light. Theoretically, like DLP technology, the consumables used are basically compatible with universal resins. Apart from the resin consumables dedicated to SLA, there is no need to worry about the difficulty of purchasing the corresponding consumables when using the LCD light curing 3d printer.
5、 The printing speed is fast. Compared with SLA, the point forming is different. LCD and DLP are both surface forming. No matter how many objects are printed, they are printed at the same time;

Then talk about the disadvantages:

1、 Key components of LCD: less selectivity of light transmitting screen; At present, the LCD light transmission screen must have good light transmission to the 405 light source, and also need to withstand several hours of high temperature baking. Therefore, the light transmitting screen is the most frequently replaced part among all components of the LCD light curing 3d printer;
2、 The overall print forming size of LCD is too small. Generally, the forming size of LCD printing is 192 * 120mm or 288 * 162mm, and the printing height is mostly 100 to 500. Compared with FDM or industrial light curing 3d printer, the overall forming size of LCD is too small.
