Manually adding support to a creation ??

softfoot

I have a project where a lot of the support material added by Slic3r is
not really needed and is very difficult to remove, but there is one area
where it is essential.

Rather than turn on "support" in the slicer is there a library or other
cleaver way to add support using OpenSCAD ??

Regards,
Dave

superslicer is a fork of slic3r and has support blockers built in, or
the opposite, you mark where you want supports, (and you can adjust
overhang thresholds, etc,which also may be  possibe in slic3r.) When you
say difficult to remove, is that because it is stuck fast to the model,
or because you can't remove it prior to running the slicer?

In difficult cases where the auto-generated support material is too
much or goes into places where I don't want to, I generate columns or
blocks where there should be support in OpenSCAD and export as
separate STL. Doing it in OpenSCAD allows you to use all the
parametric information you have anyway available.

Then I use the Slic3r-derived Prusa Slicer and import the support STL
as a 'support enforcer' and use the setting to only generate support
for support enforcers.

I often add support in my models myself, to minimize materials. I add a
boolean variable called Support and then can turn it on or off at will.

Thanks, I'll have a look at SuperSlicer

The problem is that Slic3r puts supports in places where it is
difficult/impossible to remove after printing.

I had a look at slic3r's options and it has an option to only support
from the base plate which eliminates supports inside structures, it
seems to do the job on the item I am trying to print :-)

I just wondered if anyone had created a "support" library.

Many thanks all
Dave

Yes I do the same. I suppress the support in assembly views but enable it when making the STL

I add the support manually because a library that did it automatically would tend to put it in the same places a slicer would.
