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 Print job preparation can be a time consuming task. Editing, adding supports and slicing your build jobs in a way that they actually print can be challenging. Though there are lots of slicer softwares on the market to help us simplify the jobs, those specialized for SLA/DLP/LCD 3D printers are scanty — let alone tools with stability and powerful functions. Here we listed 2020 top SLA/DLP/LCD slicer software for 3D printers for your information. Hope you’ll find the perfect fit to continue or start your totally new print journey in 2020 with your favorite SLA/DLP/LCD 3D printers.

Adding support is always a headache when it comes to photo-curing SLA/DLP/LCD 3D printing. A lot of times, there will be problems about support structures appearing in the 3D printing process more or less. A typical situation is that parts of the support structured are missing or even broken. How to solve this situation? Improper Parameters Most of the time, the missing or broken support structures are caused by improper parameters, mainly related to those following parameters. Contact Depth of Top The deeper the contact depth, the deeper the support tip inserts into the model. We need to confirm that the contact depth is deep enough to win the tug of war between the build plate and the FEP film in the bottom of the vat. With luck, it may result in deformation or misrun in the joint part between 3D model and the broken supports. If you are unlucky, there is only the raft/bottom and support structures on the build plate while the model is not printed successfully at all. Also...

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...
