supports are required. This angle results from the material, the height of the
layer, the application width and the temperature. It is especially important to
adjust the support structures accordingly to ensure optimal printing results,
especially for large 3D prints. The principle was introduced by a set designer
and is widely established in the 3D printing industry.
② The principleofproportionality
In addition to the requirement for supports, the principle of proportionality should
also be taken into account. Although a further development has taken place in
the area of the column algorithm, an intelligent addition of columns is not yet
possible. Therefore, when adding supports, users must think for themselves.
Experience shows that removing the supports becomes difficult if too many
supports are used, too few supports can lead to instability of the model on the
other hand. Since REXprint offers a manual adjustment function, users can add
the appropriate number of supports according to their needs and experience.
Column types
Linear support shape: This type of support is suitable for models with large
overhangs.
Timer functionality Full support improves model stability. However, it is not so
easy to remove the supports from the surface and this has a negative effect on
the print quality.
Supports in tree format: This type of support is suitable for models that have
small overhangs. (For such models it is recommended to print a base plate)
Timer functionality Less support material is required for this type of support and
they can be easily removed. Compared to the linear prop type, however, the
tree format props offer less stability. Therefore, it is recommended to add further
supports manually after the automatic creation of the supports in tree format, if
necessary.
