Resin(SLA/DLP/LCD) 3D Printing

Support structures are always needed in SLA/DLP/LCD 3D Printing which are one of the most important safeguard for successfully producing 3D printed parts. Support structures are used for avoiding deformation and crumbling. As the support structures are produced as an inseparable part of the whole print, post-processing is necessary to remove the visual marks left on the part. Support Structures in Top-down & Bottom-up 3D Printing Support structures in top-down and bottom-up 3D printing are not the same: In top-down 3D printing, support structures are similar to FDM. They are needed for producing accurately overhangs and bridges. As they are no peel force/separation force (Click here to know more about peel force/separation force:  How to Eliminate Z-axis Lines Caused by Peel Force/Separation Force? ) during the 3D print process, the part can be oriented in any position. In top-down 3D printing, the most crucial factors to consider is to minimize the amount of suppo...

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...

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...
