How is resin 3d printing different from lcd 3d printing?


Asked by Eliseo Schmitt on Dec 09, 2021 FAQ



Resin 3D printing involves either Stereolithography or Digital Light Processing technologies. They’re very similar — as is LCD 3D printing — with only subtle differences in the use of projectors vs lasers. Read our article here comparing SLA vs DLP.
In fact,
Resin 3D printers use liquid resin and some science to print. Compared to FDM printers, they’re a lot more accurate, more expensive, and admittedly a lot cooler to watch. Additionally, the final product is much stronger and sturdier. Resin 3D printers are available in three different 3D printing technologies: LCD, DLP, and SLA.
Next, LCD 3D Printers use an LCD display module to project a certain light pattern which is then used to cure resin in the resin vat. LED light is used as the light source while the LCD screen controls the light pattern. Light is emitted from the LED lamp. It then passes through an LCD screen and is absorbed by the resin.
Similarly,
More recently, low cost LCD 3D printers have become popular, offering better quality than FDM 3D printers can for the same price. These resin 3D printers use LCD panels using LED lights to cure resin in a similar way to DLP 3D printers.
Subsequently,
There is resin 3D printing which includes SLA, DLP, and LCD 3D printing, as well as FDM 3D printing and SLS 3D printing.
