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.

In general, the angle is preferentially 45 degrees. But it still needs to be tested. In the following content, we’ll evaluate the...

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...
