Hello all, I find that the printed parts are not very resistant to shear and bending when forces are applied 90Âº to the direction of the print (or the Z-axis). In other words, if you print a cylinder standing vertically, and you bend it, it will break quite easily. This, of course, has to do with the bonding between the layers. I was thinking it might be useful to heat treat the parts to fuse the layers. Has anyone tried this? To avoid deformation due to it's own weight, the parts most be supported in a media that wont stick to the hot (and soft ABS) and be easy to remove if some particles stick.
Sand will support well, is inexpensive but I think it will stick to the ABS and will be hard to remove. Perhaps some silicone granules or powder, or perhaps leave the parts floating in hot wax near the "annealing" temperature of the ABS. There are water soluble waxes available that melts at quite high temperatures that would make the post processing of the parts easy.
When I find time, I will do some tests and see how it turns out. Need to look into what temperature is optimal.
Has anyone tried this or given it any thought?
