3D Printing Hack structurally uses vase mode

Conceptually, FDM 3D printing is quite a simple process: you define a set of volumes in 3D space, then the slicing software cuts the model to increasing heights, works where the inner and outer walls are, and then fills. A very small amount of internal volume to bind the walls together and to support the upper layers attached at the end.

But you will find quite quickly, that when models get bigger and more complex, print times can quickly explode. One strategy for larger models with normal size but very low structural requirements is to use the so-called ‘Dani mode’, which outlines the object in a thin, vertical spiral. But it allows a weak construction project and only limited modeling complexity. With that in mind, here [Ben Eadie] One-of-a-kind halfway house techniques (video, embedded below) that may seem useful for saving some printing time and material.

This solid shape is mostly cut so that supporting ribs are made in the walls of the shell

The idea is to use vase mode printing, but manipulate the model’s shell, add a partial cut-through slot around the perimeter, and critically, add a slot that goes all the way.

First you need a model that has an inner shell that follows the approximate shape of the outside, which you can create by hollowing out a solid, leaving a small thickness. The width of the slot is equal to half the thickness of the size of the nozzle and by closing the slots at the same distance from the outer shell, the vase mode can be used to trace the outline of the shape, complete with supporting ribs between its inner and outer walls. The level.

Since the slot is narrower than the extrudate, the slot walls will be joined together in a rigid rib, binding the walls of the object to each other, but critically, allowing it to be printed in a continuous spiral without any conventional infill. This is an interesting idea, it may have some merits.

There are other ways to harden printed parts, such as using surface textures, but if you want to have a little fun with the thin shell, you can hack G-code to make something really interesting. Size.
