Resin(SLA/DLP/LCD) 3D Printing

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...

Usually, it is impossible to avoid using 3D printing support structures for overhangings and bridges as it might affect the quality of your print. When selecting the suitable support settings, your print have achieved half of success. But do you know what's the best support settings for resin 3D printing? The name of support settings maybe differ according to various slicers. In order to have a better understanding of those settings, let's take Chitubox as an example. Download ChiTuBox:  https://www.chitubox.com/download.html The support settings of ChiTubox, as illustrated below. 1. Raft Raft is the first layer which is also called attachment layer as the primary purpose of a raft is to help with bed adhesion. The raft is printed directly on the platform, then the object and support are printed above the raft. The exposure time for the rafe is at least 10 times the regular exposure time to make sure that any potential gap between the build platform and va...

When it refers to resin 3D printers, the resolution, printing size and accuracy are often discussed but difficult to understand. What’s resolution in 3D print world? What’s the relationship between resolution and printing size? Are accuracy and resolution the same one? When considering final dimensional part accuracy, what matters most: X, Y or Z? Don't be frustrated. In the following content, let's figure out those concepts. Resolution and Printing Size Resin 3D printers including Stereolithography (SLA), Digital Light Processing (DLP) and Liquid Crystal Display (LCD), use different light sources to project a complete profile of a layer. Source: robotsinthesun.org   Source: 3ders.org Thus, Resolution(width x height), is the fixed number of pixels displayed by a laser when using SLA, a projector when using DLP, an array of LEDs shining through an LCD when using LCD. The fixed nature of the build vat with liquid photopolymer results in a related build are...
