When printing models with flat bases, we can ensure adhesion to the platform by positioning that model so the flat base is flush with the platform.
Many things we want to print however, will not have flat bottoms or might have overhanging features that may not connect to resin in a previously printed layer. For example, in the picture below, we can see the left side of the surgical guide is flush with the platform and would adhere. At this orientation, the lower edge of the right side would not have any material to attach to. This bottom edge is an overhang, and needs a support structure to be able to print.
The icon on the bottom of the row on the left side of the window in RayWare opens the Support Generation Tab. There are two settings on this tab.
We strongly recommend all new users only use the default settings for support structures, and use support structures on all models unless they are designed with a flat bottom specifically to print support-free.
Density:
This setting modifies the number of pillars per square inch. Raising this ensures there are more contacts between the pillars and the model.
Strength:
This modifies the diameter of each generated pillar. Thicker pillars will leave more of a mark against the model but this will allow for printing larger, heavier models.
New users should leave these settings on default. Certain fast printing resins, like Surgical Guide and Ortho Clear do not print well on low strength settings. NextDent IBT should only be used with h/h settings if supports are necessary for your model.
Edit Support Mode:
This allows for fine tuning the exact placement of your support structures so important details can be preserved.
With this mode activated, our cursor will change and will highlight individual pillars when moused over. Clicking a pillar when Red will delete it.
Also if you hover over the model, you will see a small bubble. Clicking the model will create a pillar in contact with the model at the place of the bubble. If the bubble turns red, that means there was an obstruction preventing a pillar being placed in that location.
When using manually edited supports, it is a good practice to use the "View Print Job" function in Rayware to confirm your parts are fully supported.
