Some models don’t benefit very much from hollowing since the dimensions of the model don’t allow for much hollowing, unless you reduce your wall thickness. It concerns me when I see people injecting PLA, PetG or ABS molds because their heat deflection temperature and melting temperature are below the standard temperatures. We are going to demonstrate this point with this Moai print. Create a 3D resin print that is hollow and includes 2 drainage holes at least 5mm in diameter. Some people still choose to hollow their miniature models since the amount of resin you save definitely adds up when you are printing several miniatures. Depending on your 3D printer, when you print a hollow object it could trap resin inside the print as the layers are solidified by the laser below the liquid. If you do decide to hollow out your model, 3mm minimum wall thickness in VeroWhite is a good place to start. The critical factor with upside-down resin printers is the print adhesion and supporting structures, preventing a part from falling down due to gravitational pull. This works great for many resin 3D printer users. Solid vs Hollow. 3d prints of stretch goals will be charged as add-ons and not included! Here is how the hollowed model looks on the inside. The "self-supporting" or "safe" zone does not require any support to print the model. After filling your resin model, pour a few drops of your original resin then cure it with a UV light to harden and seal it up properly. It's perfect to create hollow prints since the resin maintains the part's strength without being brittle. Creating a hollow model means that you need to design your object with "walls". That depends on the slicer sw that you use. Under the Edit menu, there are more tools to be found: for instance, to split your 3D model into parts, or to hollow it out and generate holes for liquid resin to drain out, all in one go.
