What are the benefits of the "shell-pulling" function of light-cured 3D printing?

① Reduce the consumption of consumables.

(2) After hollowing out, the cross section changes from a large area to an outer ring, which will of course increase the cleaning difficulty when printing in a large area. If the interior of the model is not cleaned, it is easy to produce cracks after long-term storage.

Basically, all light-curing slicing software supports the function of discharging, but according to different software, the discharging algorithm may be different and the internal shape of discharging is also different.

The wall thickness is not detailed. The smaller the detail size, the thinner the inner surface, which is more suitable for the fluctuation of the outer surface, generally the same as the wall thickness, and simplifies the inner surface.

Internally, it is naturally a hollow inside the model, and outwardly, a layer of shell is wrapped outside the model to make a mold. Through advanced settings, we designed a large tolerance, a large angle, and a very simple inner surface. Increasing the percentage of smooth core will increase the complexity of inner surface. In addition, for some larger models, we may need lattice structure, you can learn about it.

After hollowing out, it is naturally punched, otherwise the internal resin will not flow out. Finally, it is best to keep the hole pile and fill the hole after printing. After the model is cleaned, it needs to be left for a period of time, and then the hole is filled after the internal alcohol evaporates. Generally speaking, LCD will expand, so it is necessary to polish the hole pile to supplement it.
