Resin(SLA/DLP/LCD) 3D Printing

The surface quality in 3D printing varies greatly as there are many factors to affect it such as layer thickness, print speed, part orientation and ect. This article discusses how to improve surface quality in 3D printing by optimizing part orientation. We put the same model in different positions in ChiTubox which form a certain angle with the vertical plane as 0 degree, 30 degrees, 45 degrees and 90 degrees. Except 90 degrees, the models are positioned in a square and rhombus at each degree angle because those two shape have different cross-sections during the 3D printing process. Download ChiTuBox:  https://www.chitubox.com/download.html So we get 7 models in total, numbered 1-7 (0°Square Orientation, 0°rhombus Orientation, 30°Square Orientation, 30°rhombus Orientation, 45°Square Orientation, 45°rhombus Orientation, 90°Orientation). In general, the angle is preferentially 45 degrees. But it still needs to be tested. In the following content, we’ll evaluate the...

There are different factors that can directly affect how fast a resin 3D printer can complete a 3D model. Choosing the right speed for your print is particularly beneficial to boost your print success and improve manufacturing efficiency. But controlling the print speed can be quite a challenge, especially if you are new to 3D printing. The first thing you have to know is the factors to affect the print speed of a resin(SLA/DLP/LCD) 3D printer. Print Technology The benefit that both DLP and LCD share, when compared to SLA, is print speed. The two technologies are typically able to produce parts faster. Because DLP/ LCD 3D printers flash a single image of each layer across the entire platform at once, while SLA flashs a single point. source: robotsinthesun.org source: 3ders.org DLP/ LCD 3D printers offer speed that often comes at a cost of precision. SLA, in turn, is more precise but relatively slow. 3D Printer The pre-fixed speed of the 3D printer is something w...
