Why My Support Structures are partly missing or broken in SLA/DLP/LCD 3D Printing?

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...

Design Considerations for Support Structures in SLA/DLP/LCD 3D Printing

Photocuring 3D printing is often used for presenting intricate objects with accurate details. Most times, we need to add support structures for overhangings and bridges. Also to increase the adhesion to the build plate, prevent warping and avoid the prints being floated around in the vat, SLA/DLP/LCD 3D printing require the use of support structures in almost all cases. Support structures in SLA/DLP/LCD 3D printing is like thin ribs whose small tips are very thin and slightly touch the part to save resin material and make them easier to remove. The usage of support structures deeply impact the print quality after post-processing work and printing success rate. So when designing support structures in SLA/DLP/LCD 3D Printing, there really is a lot to consider. Take full advantage of slicer software For most designers especially the green hand, it's perplexed to detect when and where the support structures are needed. If there is a experienced mentor to give some reasonable sug...
