- Slicing such a 3D model for printing may be computationally difficult. Imagine all the curves to analyze on a full-size knitted surface. Slicing may take an enormous amount of time or even crash less robust slicing software. In fact, the authors report the elapsed time to generate several of their models, the longest duration being 33 hours! Wait, it gets worse: the generation was done on a dual Intel Xeon X5690 CPU @ 3.46 GHz with 48 GB RAM. Not exactly your typical home machine.
- The resolution of a given 3D printer may not be sufficient to resolve the fine details of a stitch mesh. In other words, all that computation may not result in anything other than a roughly textured print surface.
