How to use support structures I made myself (import as STL in Cura)

Recommended Posts

I like to design support structures in Rhino and Magics. Once I have finished them, I usually import them into a build processor to create the print files (incl metal printers, like 3DS ProX300 and SLM280).

Now I like to print on an Ultimaker 2 or 3, with support material in the second extruder.

QUESTION: how to import my support structures in Cura ? As regular object, however assigning 2nd extruder ?

To align objects as you wish, they need to be adjusted in your 3D package so that they all share a common pivot point.

Once in Cura, load each model part separately. Then click on a part and then, in the tab on the left side, click on the icon that looks like 3 hour glasses.

This is your 'per model' settings. You can select each extruder per model as well as select most other settings that would be found in the custom tab. Speed, support, etc. Remember that most can use the common settings, so be sure that you do not overly replicate the settings.

Once all model parts have their individual settings, then select by holding down shift and clicking on each model, or use CTRL+A (Select all) or use the select all option in the edit drop down. After that, then (with all model parts still selected) go back to the edit drop down and choose "Merge Models". this will align all selected model parts and use the pivot point to align them and then group them.

To adjust the settings, if you change your mind or think of something, you have to ungroup (In the Edit drop down) and then make your change(s). Then you go back and merge them again.

No need to ungroup. You can also Ctrl-click (or Command-click) an individual object that is inside a group. Ctrl+Shift-click also works to select multiple objects, even in different groups.

Thank you. I will try this.

1) So you do not recommand to use another environment for this (like Craftware)

2) One cannot use surfaces without volume (so no thickness) to print something as thick as a single line ? Minimal width would be the diameter of the nozzle ?

Tnx !

However, as well as select most other settings that would be found in the custom tab  ... what is to you the custom tab ?   The setting that are specific for each individual extruder ?

In the 'per model settings' they are "Per Model" regardless of the extruder. For instance, you can change the speed of each model and such. Each model can have its own support settings (from within Cura) such as overhang and all. But, in the materials grouping there are only two of the 25 or so available settings: Default Printing Temperature and Flow. Some things must remain common as it is currently designed.

I am guessing it is the mathematical relationships as mentioned by ghostkeeper of Team Ultimaker in another thread (variable Layer Heights on a print), so you will not always find all the custom settings in the per model area.

But the simplest thing, as you have requested is to be able to tell your support models to use the extruder with the PVA filament and leave the rest to the common settings on the right hand side of the interface.

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
