As a special service "Fossies" has tried to format the requested source page into HTML format (assuming markdown format).
Alternatively you can here view
the uninterpreted source code file.
A member file download can also be achieved by clicking within a package contents listing on the according byte size field.
Useful 3D printing tools
- surface area
(if you gold plate for eg, or use expensive paint :))
- degenerate geometry
- solid geometry
- non-contiguous normals (bad flipping)
- basics - stray verts, loose edges
- degenerate faces, bow-tie quads
- visualize areas of low wall thickness.
- visualize overhangs (some printers have this as s limit).
- areas of low wall thickness.
- sharp/pointy surface.
- add text on an object (common tasks - lots of people want this to add a name to personalize items)
- Rig sizes (rings also common item to make)
- nice UI with format select and output paths for the print.
no need to recode re-use existing exporters, maybe recode some in C if too slow.
Integration with toolplating
(the thing that gets the model into printer commands)
- Use a sliver, like slicer, skeinforge, cura, kissslicer, netfabb, ….
…not sure yet exactly how this would work, but we could have a
Print button and it would send the file off and print :).
- Normals are important
- Self intersections can be ok.
Some printer software already prevents solid areas from taking too much space by filling with non-solid grid.
(So we may not have to care about solid shapes so much)
For extrusion printers like makerbots it is really hard to print “overhangs”…
because they build “from the bottom up” they can’t for instance make an arm sticking out of a character sideways
