Resin(SLA/DLP/LCD) 3D Printing

3D Model: Siperman Resin: LCD Rigid Resin GS-B11 Slicer: ChiTuBox  V1.5.0 Model Source: https://www.thingiverse.com/thing:3306294 In ChiTuBox, there is a related parameter about support tips called "contact shape". You can choose "none" shape or "shepre" shape as shown below. Now let’s test the effect of these two shapes on the support removal and the surface quality of the object. Download ChiTuBox:  https://www.chitubox.com/download.html First, let’s deal with the "shepre" shape (label as No.1). According to the last test ( Improve Surface Quality in 3D Printing by Optimizing Part Orientation ), we put the sipderman in ChiTubox which form a certain angle with the vertical plane as 30 degrees to receive relatively good surface quality. The support structures are automatically generated by ChiTuBox, but then we manually adjust some. To ensure successful 3d printing and show how contact shapes affect support removal and surface quality, a...

Photocuring (SLA/DLP/LCD) 3D printing is one of the most popular 3D printing technologies which can create prototypes with very high quality, fine features (thin walls, sharp corners, etc.) and complex geometric shapes. Although this technology has so many advantages, the 3D models may still be very rough if you are not familiar with slicing, printing skills, etc. In fact, the quality of 3D printing has a lot to do with the equipment, materials and slicer. We can improve the quality of 3D printing by just adjusting the following settings. Download ChiTuBox:  https://www.chitubox.com/download.html Layer height (mm) As the name implies, layer height is the exact height of each cured layer. Layer thickness not only affects the speed (printing time), but aslo the quality of each print. The number of layers required to create an object determines the printing speed and thus the printing time required. The thinner the layer thickness, the longer it takes to make a 3D printed objec...

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...
